Double-Hung Windows For Landmark Townhouses

Open AWD: Experts in Historic Window Replacement

For over 14 years, Open AWD has been trying to right this wrong by supplying first-class Double-Hung Windows to homeowners and architects seeking to restore landmark projects to their original beauty.

The United States is a country where landmark buildings are highly esteemed yet it’s not uncommon to see neglected brownstone townhouses scattered throughout New York, Boston, or San Francisco.

Take, for example, an old townhouse in Brooklyn Heights. The owner is tired of drafts and leaks, and they would like to replace them. No element of renovation – or even construction – is harder than choosing which windows are right for your home, and there is much to consider. 

Open AWD: Your Partner in Landmark Renovations

NYC Landmark Preservation Commission Logo

In many towns and cities, there are areas where double-hung windows are required due to each city’s historic zoning regulations. In many cases, only double-hung windows are permitted, and local landmark commissions strictly enforce this.  It is crucial to understand your local zoning regulations before ordering anything. 

Windows and doors on the front facade should be designed to complement the architecture of the building and the surrounding subtly and effectively. You can read more on some design options for double-hung windows below.

The Case for Double-Hung Windows

True Double-Hung WIindow

The original design and functionality, combined with the modern capabilities of the IGU double-circuit seals and hardware, are both classic and modern.

Single-Hung Window

Based on our opinion and our research,  people often only use the lower sash. As a result, if the upper sash is rarely used, a single-hung window is a much better idea. In terms of soundproofing and energy efficiency, it will require less hardware and, as a result, will come with a lower price.

Simulated Double-Hung Window

We developed a combination of traditional-looking windows and technical European style. Because of their construction, simulated-hung windows can actually be more energy-efficient than true double-hung windows. This is because they have more moving parts, which increases the likelihood of air leaks. The sliding sashes allow air to enter or escape, especially if the windows are older and have not been properly maintained or weatherstripped. A huge difference is a sach multipoint locking system where the sash is pressed tightly against the frame along the entire perimeter and does not slide along the guides in the frame. This allows us to achieve the best thermal and sound proofing performance. We use limiters, which ensures safety; all our windows comply with the New York code requirements.

Insect screens are available for any opening types.

Considerations Beyond Style

The main advantage of using wood for landmark windows is that it can be customized to match the exact measurements of the original window. Firstly, there’s wood, a classic choice with various types such as Scandinavian pine, ash, and oak. Also, we use teak, mahogany, and other exclusively sorted woods.
However, it’s important to understand that a wooden window with glass is always a wise choice.

Cladded wood Double-Hung Windows

For a more modern look, a combination of wood with metal cladding can provide both coziness in the inside of the house and style on the outside. Seamlessly blending with the architecture, wood-clad metal windows are also resistant to environmental challenges.

You can learn more about this type of windows and the available hardware by downloading the detailed catalog here.

Industrial style. Hardware solution of Double-Hung Windows

Balances:  Balances are mechanisms within the window frame that help counterbalance the weight of the sash, making it easier to open and close the window smoothly. There are various types of balances used in single-hung windows, including block-and-tackle, balances (also known as coil spring balances). 

The world of windows can be daunting and overwhelming with technical jargon and many, many different parts to choose from. With this guide, we’re going to introduce you to some of the more common types of window balances, explain how they function and give a brief overview of how to replace them. If there isn’t a direct replacement, as is common, we will discuss newer, modern technology that you can convert your windows to. 

Balances: Traditional double-hung windows are counterweighted, using two window balances concealed within the window frame. The weight of the balances help offset the sash’s weight, making it easier to open and close the window.

What is a Double-Hung Windows Balance?

A window balance (sometimes called a sash balance, window spring, or window “balancer” is a somewhat hidden window component sitting inside the window frame. Window balances are only found in double-hung or single windows and counterbalance the weight of the sash assisting you with opening and closing your windows. Window balances are found in both residential and commercial windows. 

There are four common window balances found in residential windows. We’ll introduce them to you from the oldest to the newest.

Cord and Weight (Chain and Weight)

Double Hung window details Drawing

The cord and weight balance system was the first type of balance system installed in sash windows. If your home has older wood windows they may operate with a cord and weight or chain and weight balance system. 

Fun Fact: Prior to the invention of this counterbalance system, the operable sash had to be propped open with sticks, hinge systems↗

How do cord and weight window balance systems work? 

Windows with cord and weight balance systems have a box built into each side of the window (the jambs) where cast iron or lead weights are suspended. The weights are attached to a cotton cord that extends up the jamb, over a pulley, and onto the operable sash. 

In order to counterbalance the weight of the window, the weight in the jambs has to match the weight of the sash. Equal weight creates a perfect balance and allows the window sash to move smoothly.

Rope and Pulley Double-Hung Windows Balances

In order to counterbalance the weight of the window, the weight in the jambs has to match the weight of the sash. Equal weight creates a perfect balance and allows the window sash to move smoothly.
Rope and Pulley Window Balances
This is the original window balance system. This type of window balances uses large weights to counterbalance the sash. These weights are hidden in cavities beyond the jambs. The weights are connected to ropes or chains and travel up and down as the sash is raised or lowered. The most common problem with this type or balance system is that the ropes will fray and break over time. The most common solution to this problem is to simply replace the chains. Depending on your window you may be able to upgrade to a newer balance system.

Constant Force/Coil spring

How do constant force window balances work?
Constant force window balances work by using a stainless steel rolled coil spring. The spring is similar to a tape measure that extends and coils and, like other balance systems, it’s located in a pocket in the jamb. Manufacturers use a computer program to provide the perfect counterbalance for each window based on the window’s dimensions. The window’s dimensions determine the number of coils used in the balance system.
The spring in this system should hold its tension forever, in fact, most windows with this balance offer lifetime parts warranty. This system doesn’t use cords that can wear and tear or parts that can rust.

  • This balance system rarely breaks down
  •  Usually covered by a lifetime parts warranty
  •  The spring should never lose tension

Coil Spring Double-Hung Windows Balances

Coil spring window balances are a type of constant force window balance. These balances work by using stainless steel, coiled spring as a counterbalance. This type of balance system is designed to be more durable and quieter than other balance systems. There are several parts to a coil spring balance system: the coil, the balance spring cover, the balance drum, and the pivot lock shoe. To find replacements for your balances it is best if we have pictures of your current balance system along with your sash weight.

Clock Spring Double-Hung Windows Balances

Clock Spring window balances are an older style window balance, often found in older wood windows. This type of balances is similar to the previously mentioned coil spring balances in that they use a coiled metal spring to counter balance the weight of the sash. There are a two ways these balances can be mounted in your jamb, overhead or side mounted.

6 Jambs: The jambs are the vertical parts of the window frame that help hold the sashes in place when the window is closed. They play a vital role in providing a secure seal to prevent drafts, water infiltration, and noise from entering the building.

9 Locks and Latches: Single-hung windows come with locks or latches that secure the window when it is closed. These locks are essential for ensuring the window remains shut and also provide an added layer of security to the building.

Sash locks are mechanisms located at the meeting rail that secure the two sashes together when the window is closed. They ensure a tight seal and improve security by preventing unauthorized access from the outside.
In modern double-hung windows, jamb liners are often used instead of traditional window balances. Jamb liners contain the window balances to aid in the smooth movement of the sashes.
Understanding the various parts of double-hung windows not only enriches your knowledge of architecture but also empowers you to make informed decisions when maintaining, repairing, or replacing these windows.

Whether you are preserving the historic charm of an old home or seeking to enhance the beauty of a new one, double-hung windows offer timeless elegance and functionality that continues to withstand the test of time.

Situated atop a hill, this house, showcased our ability to marry architecture with nature. The house’s largest part cleverly concealed behind the hill unveiled a masterpiece. With its stone wall decorations, and windows and doors crafted from ultra-slim graphite steel profiles. The challenge of installing oversized units was handled by our certified installation company. A highlight of this project was the glazed hall. It was featuring one of the largest glass units, measuring an impressive 9 by 19 ft. In total, 39 windows and doors 2373 sq ft.

Corten Steel Portchester NY – Historical Transformation | Exterior Units

In Portchester, New York, we undertook the challenge of transforming a historic building originally constructed in 1880. The client’s request to replace the wood storefront with corten steel led to innovative solutions. Preserving the building’s historical significance while infusing contemporary design, we experimented with techniques like brashing from soft fibers. This transformation resulted in 7 windows and doors, covering 412 sq ft, showcasing our ability to harmonize innovation with historical detail.

Franklin Street – A Touch of History | Exterior Units. Landmark

The Astral Apartments, located on Franklin Street in the Greenpoint Historic District, Brooklyn, stand as a testament to architectural ingenuity and social consciousness. Erected between 1885 and 1886, this iconic structure was conceived by Charles Pratt to provide affordable housing for the labor force of his Astral Oil Works.

Spanning an entire city block, the Astral Apartments exude grandeur with their Queen Anne-style architecture, characterized by a brick and terra cotta façade. Noteworthy features include a prominent central section projecting outward, boasting a deep, three-story-high round arch recess, and a roof adorned with intricate decorative grotesques.

Beyond its architectural allure, the Astral Apartments once offered a host of amenities aimed at enhancing the lives of its residents, including a settlement house, library, and kindergarten. Additionally, it housed a branch of the Pratt Institute Free Library, serving as a hub of knowledge and community engagement.

We received a request to replace all the entry doors in this building. Some of the doors were rectangular in shape, but when viewed from the facade, we replicated the arch’s geometry, giving the illusion of them being arched from the outside. Accordingly, each profile width was adjusted to a specific opening. You can also notice that there are double-leaf doors and single-leaf doors, although their appearance is similar.

Special moldings were also used on the walls, along with additional linings. When you open the door from the inside, you do not see a bare wall but a wooden panel. All the units are made of wood and equipped with electric door closers and premium-quality hardware.

Nantucket Waterfront Residence – Coastal Elegance | Interior Units

Our project at Shimmo represented coastal elegance with a rare waterfront offering. This interior project, featuring white ultra-slim profiles (Presto XS), sliding doors, oversized fixed interior partitions, and triangle-shaped partitions, aimed to capture the breathtaking views from Nantucket to Great Point Lighthouse.

Columbia Pl – Modern Touches in a Brooklyn Heights Gem | Interior Units

Columbia Place is a regular stop on architecturally-oriented walking tours of Brooklyn Heights. It’s a quiet street, protected from the noise of the Brooklyn Queens Expressway by Alfred T. White’s apartment building.

We received a request for interior units in a single-family home that was built in 2003.

Among the units were a sliding window with fixed sidelites serving as a dining room partition and a single interior door. Units were made from Steelline profiles coated with VeroMetal. The customer opted not to install any guide parts on the tabletop, so a system of synchronous window opening was provided.

West Canton – Space-Saving solution for a Boston Brownstone | Interior Units

Our most common projects involve buildings with landmark status. Additionally, we specialize in manufacturing exterior windows, doors, curtain wall systems, interior partitions, and various types of doors.

For a recent project located on West Canton Street in a brownstone townhouse in Boston, there was a request for a folding door. The apartment owners wanted to separate the space between two dressing rooms using a partition. We crafted a folding door composed of three sections from a steel profile. The unit was powder-coated with anthracite paint and equipped with premium quality hardware.

Going Forward

As we move into 2024, Open AWD remains committed to pushing boundaries, embracing challenges, and delivering innovative solutions that outmatch our clients’ expectations.We would like to thank our dedicated team, valued clients, and partners for making 2023 a year of resilience, growth, and architectural excellence.

Innovative Design and Cladded Wood CONSTRUCTION in The Heart Of Brooklyn

Nestled in the heart of Brooklyn, our recent project at property on the 2nd Place offers residents stunning views of historic Carroll Gardens, and is complemented by the tranquility of the area’s unique townhouses. We were delighted when asked to come on board and join the project. In collaboration with architects, our goal was to seamlessly integrate the cladded wood windows and metal panels, and create a visually cohesive unit that blends harmoniously with its surroundings.

Front view of cladded wood window with section drawing construction.

Innovative Waterproofing in Cladded Wood Window Construction

The residents’ prior encounters with window leaks served as a strong reminder of the importance of delivering a high-quality solution. Given the house’s recent construction, our primary objective was to ensure a long-term resolution to this issue.

One of the key challenges during the project was placing all the windows outside the load-bearing walls. This engineering solution is designed to increase the structural integrity and aesthetics of the building. However, it required careful planning to ensure effective waterproofing and thermal insulation.

That dedicated team of engineers has carefully designed the waterproofing system, taking even the smallest details into account. Additionally, the aluminum wall panel located between the windows has a layer of 2″ extruded polystyrene foam for thermal insulation, which provides ample insulation.

A typical cladded wood window profile is made of Scandinavian pine with aluminum cladding. The windows, painted white on the inside, perfectly complement the interior. Additionally, this profile is highly popular among developers. The timeless black external aluminum overlays lend the building a classic feeling.

On the first floor, we have an arch-shaped window, adding a unique element to the facade.

15,000 SQ. Feet of Custom-Made Curtain Wall System In Manhattan Showroom

In 2019, Open Architectural Windows and Doors was contacted by a team of architects to design a custom-made curtain wall system, as well as windows and doors, for a project in Manhattan. The project, which consisted of 15,000 sq ft of glass, was for a car showroom. We had completed a wide range of commercial, residential, and high-value projects before, but never a car showroom. After we met with the client and got a better understanding of what they were looking for, we were very excited to join the project.

Choosing The Perfect Showroom Сustom-Made Curtain Wall System

Front View of The Manhattan Showroom before the Curtain Wall Installation

When we first met with the client, they had originally been looking for an aluminum custom-made curtain wall system. Aluminum systems are relatively common for showrooms. However, because the showroom was located at the edge of Manhattan close to the water, it was subject to more stringent guidelines. New York City has specific guidelines governing a structure’s capacity to withstand high winds.

While aluminum could be used for a project like this, it would not be possible to achieve the kind of slim profiles that would be possible if steel were used. For example, you might need a mullion with a depth of up to 12 inches to ensure that it is able to securely keep the IGUs in place. Even at that, aluminum would require steel reinforcements inside the mullion to provide the requisite strength. It would take far bigger and thicker aluminum mullions to keep the IGUs in place. In that sense, slim profiles are not easily attainable with aluminum.

Steel, on the other hand, is much stronger, and provides a wider range of possibilities. This becomes an important issue in projects where oversized IGUs (or jumbo glass) is used. The main challenge we had to overcome was achieving the requisite mullion strength in order to hold the IGUs in place and withstand high wind load. We were able to use 6 inch deep profiles for vertical spans of up to 24 feet.

After much discussion, our client was very pleased to go forward with a steel curtain wall system. In addition to this, they asked us to design all of the metal paneling around the showroom as well as two custom-made awnings for above the doors. Once the steel for the curtain wall went into production, we began finalizing the oversized IGUs.

What Are Oversized IGUs or Jumbo Glass?

Oversized IGUs, also known as jumbo glass, are simply IGUs which are larger than standard-sized IGUs.

They are often used in buildings with modern designs or in retail spaces, such as shops, museums, and showrooms because they offer better, uninterrupted views.

They provide greater freedom for the architect, far more natural light, as well as a greater sense of openness within a space. This is why they they are standard in modern showrooms.

On the technical side of things, oversized IGUs provide a greater degree of thermal resistance than standard-sized windows.

Larger IGUs mean fewer joints and weak spots (which allow heat to pass through). This means greater thermal efficiency and maximum comfort.

Oversized IGUs make it easier for the architect to achieve clean, beautiful lines within the overall design. While they also create more opportunity for exposure to sunlight, any unwanted heat gain can easily be avoided by adding coatings, such as Low-E. This also controls any glare from sunlight.

Two construction workers in a suspended platform install large insulated glass units on a building facade, using scaffolding platform to access the exterior, and a suction-lift device attached to a crane to maneuver the oversized glass panels of the custom-made curtain wall system

While oversized IGUs are very visually impressive, they come with certain challenges and considerations. One of the most important is wind load. In our case, we worked closely with the engineer to determine the exact thickness to withstand high wind loads. We settled on 1/2 inch thickness, in certain areas, for the outside glass.

As of today, the largest IGUs produced in Germany are in sizes of up to 10.5ft x 61ft. Increasingly, more customers are requesting oversized IGUs for their projects.

Designing The Showroom’s Custom-Made Curtain Wall System Awning and Paneling

The architect also asked us to design two awnings as well as the exterior paneling to complement the showroom. Undoubtedly, designing the two awnings made for some of the most interesting work on this project. As you can see below, we decided on a large pane of specially-designed tempered and laminated safety glass above each door. This ensured it could withstand wind-loads as well as any other unexpected loads, such as heavy snow. Encased in a steel frame, the canopy was a striking addition to the project. We used stainless steel spider fittings to hold in place each panel of glass.

To design the metal paneling you can see around the building, we spent hundreds of hours researching and mocking up samples. We used 3D modeling software to arrive at the exact look we wanted for the panels. You can view some of the drawings as well as the final product below.

Installing The Custom-Made Curtain Wall System Glass

Workers in hard hats and safety gear use an robotic glass manipulator equipped with multiple suction pads to hold the glass securely cups to install a large glass panel on the exterior of a building where are visible  reflections of nearby buildings on the glass panel.

Designing and manufacturing oversized IGUs requires specialized machinery; installing them requires the use of spider cranes and manipulator. Logistics are a problem. Entire streets must be shut down to allow for trucks to pass through and unload. To do this, you must obtain permits must from the regional authorities. Only experienced companies are equipped to design and provide oversized IGUs for you. Similarly, only certified and licensed installers are equipped to handle such projects. All of our projects are handled by an external licensed and certified installation team we cooperate with.

Commercial Windows: Choosing The Right Windows and Doors for Commercial Properties

When it comes to designing, building, or even renovating a commercial property, it is important to ensure that you have everything covered. More often than not, windows and doors will represent the second greatest expense to a new-build, so it’s important to ensure that you pick the right ones. Whether you want to fit a series of wooden windows to re-invigorate your storefront, or have a series of custom-made bronze, copper-clad windows designed for your multi-level boutique hotel, there can be many things to choose from. And with so many Americans spending so much time at their place of work, it’s important that windows strike the right balance between comfort and performance.

From shops to hotels, from car show-rooms to museums, we have done it all here at Open Architectural Windows and Doors. So, we decided to put together a short article for you giving you insight into the three most important things to look out for when choosing windows for commercial properties–materials, aesthetics, and efficiency. We when we’re working with customers to help them figure out what what they need, we like to tell this: Form (material and style) should follow function (what do I need the window to do?)

Materials

The kind of material and style of commercial windows will largely depend on the kind of building and what it will be used for. Also, environmental factors, such as whether it is close to water or exposed to unusually high winds, and regional codes, such as whether the building or its surrounding neighborhood are historic landmarks, may also play a role in shaping your needs. For example, in coastal areas where there is both moisture and salt in the air, metal windows will hold up much better than wooden windows.

Choosing The Right Material for Your Windows and Doors

As we’ve said, there is no one right material to choose for commercial windows and doors. The material you choose should be a combination of aesthetics and needs, and takes any environmental and regulatory factors into concern. Whilst wooden and vinyl windows have been a popular choice over the past several decades, more and more people are turning to materials such as aluminum, steel, and even bronze. The main reason for people choosing metals such as aluminum and steel is the fact that slimmer profiles are easier to achieve with those materials. Wood, however, remains a classic choice and is a particularly popular choice for traditional shopfronts. One increasingly popular look is wood-clad windows. This is a combination of wood and aluminum, which allows the client to keep the feel of wood indoors, and all of the protection of aluminum outside. You can learn all about these here.

Choosing The Right Glass

The process of testing the strength of glass used in windows and doors involves striking the glass with a heavy hammer to evaluate its durability and impact resistance.

Of course, windows and doors don’t just consist of frames– glass plays a very important role, too. Indeed, when it comes to choosing glass for commercial windows, two features are of paramount importance: impact and sound resistance.

Firstly, it should of course go without saying that commercial properties need to be safe and secure. After a property’s entry door, its windows are the most likely point of entry for anyone attempting to break in. With this in mind, it should be clear just how important windows are to any building’s security. Break-ins in any building can be very inconvenient for those involved. They can become even more inconvenient if there is cash or stock on the premises. Therefore, each client should also consider whether or not they will need reinforced, or breakthrough resistant glass for their property.

This involves tempered glass with extra layers of polycarbonate glazing on the exterior as well as in between each layer of glazing. When attacked with tools, the glass will never shatter, but only begin to crack under extraordinary pressure. You should also consider anti-burglary fittings on all windows. This will be more of a concern with ground level storefronts and much less so with multi-level units. You can learn more about all of these in our dedicated article on high-security windows and doors

Noise pollution can be an issue in urban areas. As a result, Open AWD strongly recommends investing in windows with quality soundproofing. Whether you own a small business, or a sprawling office development, noise pollution and soundproofing is something you need to consider. This is particularly important if a building is within earshot of traffic, car horns, low-flying airplanes, sirens, construction noise, or even loud neighbors, your home will be subject to much low-frequency (i.e. loud noises from a distance). Many windows are unable to withstand such low-frequency noise. If that’s the case, then your window might only let it unwanted noise, but could also cause vibrations, too. In this instance, you would need a lower STC rating.

Commercial Windows and Doors Aesthetics

They say don’t judge a book by its cover. But, as we’re sure you’ll agree, many people will look at a property’s facade–specifically at its windows and doors–and make assumptions about what the interior looks like. The kind of window you have, generally-speaking, should be a reflection of taste. As a result, they should provide ample natural light and comfort for those within the building. Natural light is incredibly important to any space, has many natural benefits, and can cut down on costs associated with artificial lighting. As a rule of thumb, larger windows will allow in more light and create a brighter, livelier and more inviting environment.

Windows and Doors Style

There are many different commercial window styles available. Each style comes with its own unique benefits. Some styles will suit more traditional homes better; whereas others will be more at home on more modern and contemporary buildings. There has been a trend towards more slimline windows in recent years. In our experience, this is a trend which has increased year on year. As a result of this, muntins—which were historically used as structural components to divide panels of glass within a window—have become slimmer. Ultra-slim profile windows will ultimately have quite a different impact on your facade than choosing slightly thicker, more traditional ones.

That being said, each project demands its own approach. Whilst steel is becoming more and more popular, some projects demand wooden windows and doors. For example, we re-desisned and re-fitted this storefront in Manhattan’s East Village a few years ago. As it turned out, the building had been designated a landmark by New York’s Landmark Preservation Commission. Its facade, however, had been completely plastered over in a previous renovation. A previous contractor had replaced the once beautiful windows with cheap, low-quality windows. Open AWD were contracted to redesign these. You can see pictures below and read about the entire process here.

Explore Your Options For Commercial Windows and Doors With Oversized IGUs

Windows come in all shapes and sizes. Windows for a traditional storefront will, for example, look very different from the windows in a modern showroom.

As such, we recommend exploring all of your options for custom-sized IGUs (insulated glazing units). Standard-sized IGUs will suit many commercial properties.

However, when it comes to bigger buildings, oversized IGUS (also known as jumbo glass) are certainly more popular. This is true of buildings such as sky-scrapers, showrooms, museums, and many buildings which feature modern design. Oversized windows are often an integral part of modern architecture. They contribute massively to the overall appearance of a building. For example, take a look at some pictures of oversized windows we installed at a luxury car showroom in Manhattan. For more on oversized IGUs, read our article on them.

Color

Wood, aluminum, and steel can be finished in almost any color. This means that you can choose a color that either complements, or stands in contrast to, the building. Wooden windows can be easily painted in any color. They will, however, need to be repainted multiple times over the course of their life. Aluminum and steel are much easier in that regard. They can be finished in any RAL color. The finishing process is known as powder coating and powder-coated steel can last up to twenty years and will require much less maintenance. Metals such as bronze or copper need the least amount of maintenance. In fact, their patinated appearance will actually improve over time and continue to age gracefully.

Efficiency of Windows and Doors

Efficiency within commercial windows is always a real concern. As we pointed out, because people spend so much of their time at work, it’s important to ensure that windows are efficient. Efficient windows can maintain a cool temperature in warmer weather, and maintain a warm temperature when it’s cold outside.

U-Factor and R-Value

U-Factor (also known as U-Value) is one of the most important aspects of choosing commercial windows. It measures how effectively a window can retain heat inside a home and reduce heat loss. The lower the number, the more heat it retains. So, a window with a U-Factor of 0.20 will retain heat better than one with a value of 0.5. The climate you live in plays a very big role in determining the U-Factor you’ll need your windows to have. More on this below.

Windows have an enormous effect on a wall’s R-Value. R-Value is the rate at which a material resists heat passing through it. A high R-Value means the material (e.g. insulation) is effective at resisting heat flow. As you can see from the diagram, windows with a lower U-Factor can dramatically increase a wall’s R-Value.

Solar Heat Gain and Coatings

Solar Heat Gain Coefficient (SHGC) is the amount of heat that enters a building via its windows. Most of this heat will be natural heat (radiation) from the sun. The lower the number, the less heat it lets in. Conversely, windows with a high SHGC level will allow more heat into the building. This is a very important factor consider–particularly when it comes to larger buildings with more (and bigger) windows.

Natural sunlight bring in some much sought after sunlight and heat. However, it also brings in ultraviolet rays which cause floors, walls, and fabrics (sofas; cushions etc.) to fade over time. These rays also can cause harm to our skin. To combat this, microscopically-thin, completely see-through, metal coatings were created to lessen the impact of this. Low-E (low-emissivity) coatings use silver to reflect heat. In summer, it reflects the heat entering a house; in winter, it reflects the heat leaving. So, in essence, it functions very similarly to a thermos–it allows you to maintain the desired temperature inside. Warm when you want it to be warm; cold when you need it to be cold.

Within Low-E coatings, there are a number of different ways to adjust the amount of heat which passes through your windows. This can be achieved by adding additional layers or by altering which panels are coated. The level of protection you need will depend on your environment. Also, it will really matter whether or not your house is in the shade.

Gases

Gases also play a very important role in the overall performance of windows and doors. Traditionally, the space between panes of glass was left empty. However, advances in technology have shown certain gases (which can be denser than air) can actually reduce heat loss in your home. The most commonly-used gases are argon and krypton. Of those, the most widely used gas is argon. Argon can significantly reduce unwanted heat loss. Argon has a thermal conductivity rate 67% lower than air. In windows with argon gas, argon usually makes up roughly 95% or more, with air usually comprising 5% or less. Double and triple-glazed, argon-filled windows are some of the best performing windows available on the market.
