Glass & Installations

A critical and often-overlooked aspect of windows is the window glass itself. You may be surprised to discover how many types of window glass are available and how many purposes they serve. When you choose WindowFix for window replacement, installation, or updating, you can be confident you’ll get superior windows, down to high-quality glass specially manufactured for your needs.

Glass Types

When choosing a new window or door, many people think about the style, the color, and the hardware to match. What people don’t usually think about is the type of glass. Since your home or business may have specific needs, choosing the right glass is important.

Glass Services & Information

Curtain wall glass is a non-structural combination of glass and lightweight material used for commercial buildings worldwide and in many private homes. Although often used for the exteriors of buildings, curtain wall glass can be installed anywhere for modular space separation, light or glare reduction, security and sound control, energy efficiency, and more.

Fire-rated windows meet the NYC fire code regulations mandated for businesses. Fire-rated glass protects against flames and smoke and slows the spread of fire. It also maintains integrity up to 1600 degrees, so it won’t shatter into dangerous shards during a fire.

Insulated glass is used for double-pane windows, in which two glass panes are sealed together with space between for krypton or argon gas. Insulated glass blocks heat rays from the sun and retains heating and AC, saving you money on climate control. Condensation can form when the seal between the panes breaks, but our insulated glass is guaranteed against condensation.

Also called double-pane glass, it consists of two pieces of glass, with a moisture-absorbing sealant between them. Insulated glass can only be installed into windows or openings that are prepared for this purpose.

What Causes Fog or Condensation in Between the Glass in Your Windows?
When the seal between two pieces of glass breaks, it begins to let air in. The difference between the temperature indoors and outdoors causes condensation — moisture collecting in the space between the two panes

We guarantee our insulated glass against condensation. All of our insulated glass is factory-sealed and prepared in minutes. We will install our insulated glass into your existing window at a much lower cost than buying a new window. Any shape can be cut. Most glass up to ¼” thick can be insulated or made into a double pane. Window-Fix uses a patented technology that delivers absolute performance by taking insulating glass spacers to the next level.

Low-E glass, also known as low-emissivity glass, is treated with an invisible metallic coating that lets in light but reflects heat and reduces the UV rays that fade interiors. This energy-efficient glass also keeps heat inside in the winter and prevents the greenhouse effect caused by direct sunlight.

WindowFix’s Low-E Glass solutions meet all ENERGY STAR® programs, Low-E products have established new standards for energy efficiency and year-round value. For homes, businesses, and architectural projects, Low E Glass offers day-to-day comfort and year-round energy performance. Whether you are focused on annual energy usage, views, daylighting, or glass appearance, Window Fix Low-E products deliver highly customized value.

What is Low-E Glass for Windows?
Low-emissive or “Low-E” glass is window glass that has been treated with an invisible metal or metallic oxide coating, creating a surface that reflects heat, while allowing light to pass through. Windows treated with Low-E coatings are proven to reduce energy consumption, decrease fading of fabrics, such as on furniture or window drapes, and increase overall comfort in your home.

How does Low-E Glass Work?
Low-E glass reduces the amount of ultraviolet light that enters your home, without blocking visible light. Depending on your home’s heating and cooling needs, Window-Fix offers various types of Low-E glass o allow for high, medium or low solar gain.

Super Energy Efficient Glass is the Way to be Sustainable
Serious Materials upgraded the 6,514 dual pane windows in the Empire State Building by reusing all existing glass and creating super-insulating glass units in a dedicated processing space located onsite in the building.

Triple-Pane vs. Suspended Film
The transition from single-pane glass to dual-pane (with a single-insulated unit) provided an improvement in thermal performance. The introduction of multi-chamber glass packages – created by two or three suspended, wavelength-selective thin film technology – allows for significantly improved energy savings performance, superior durability and longevity, and installation advantages over triple-pane glazing solutions, depending on location, building type, and other factors.

Extra Weight of Triple-Pane Glass Compromises Functionality, Durability, and Ease-of-Installation
Triple-pane glass units can be significantly heavier than standard insulating glass. The heavier glass requires stronger framing systems which can increase the overall cost of any building project. The extra weight can also impose strict size constraints and may affect how much glass is used in the design of a building – impacting the overall aesthetics of a structure. The general functionality of triple-pane windows is also affected by their weight. Additional stress is placed on all operable mechanisms in the window and the window hardware, wearing them out quicker.



Due to increased demand during the pandemic, WindowFix has added customized protective barrier glass systems to our products and services. Protective barrier glass can be used in a wide range of environments to reduce the spread of viruses and bacteria while maintaining a clear line of sight for conducting business.

In response to demand from business owners and the general public, WindowFix is adding to our list of products and services. We now provide protective barrier systems custom-made to our client’s needs. With the right solutions, you can maintain line-of-sight between your employees and customers while guarding against the possible spread of bacterial and viral infections via breathing, coughing, or sneezing.

We fabricate and install sneeze guards or protective barriers for:

  • Reception desks
  • Counters
  • Grocery stores, including barriers for checkout stations
  • Food display cases
  • Business offices
  • And more

Additionally, we offer interior glass partitions for numerous applications. Material options include acrylic, annealed glass, or tempered glass in framed or frameless systems.

Do you know the disadvantages of using Plexiglas as a sneeze guard? 
As more and more small businesses open, many business owners are rushing to have Plexiglas installed, not realizing the negatives behind this acrylic material. Before you choose Plexiglas for your commercial sneeze guards, consider these disadvantages:

  • Prone to discoloration and reduced transparency over time
  • Highly rigid, making it more likely to crack during drilling or upon impact
  • Susceptible to chipping
  • Not fire-resistant
  • Difficult to clean

In a partnership with Gamco, Window Fix is now offering a more elegant solution in place of Plexiglas. Our low-iron glass with anti-stain coating reduces debris buildup, making it easy to keep clean with no discoloration over time. Having high-quality, long-lasting protective barriers in place when your business reopens will help you attract and serve your customers as safely as possible.

Often requested to meet New York City Code or design specifications, WindowFix carries a full line of safety glass products that offer greater resistance against breakage and protection on impact. Safety glass protects by resisting breakage. Glass safety barriers provide security without obscuring your line of sight. Types of safety glass include:

  • Ballistic + Blast-Rated
  • Heat-Strengthened
  • Hurricane Rated 
  • Impact Rated 
  • Laminated 
  • Polycarbonate
  • Tempered
  • And combinations of…

Being based in New York City, we receive calls every day for our guidance on how to reduce sound. No window we use is completely soundproof, but there are a number of options to reduce noise significantly, even on the loudest streets and avenues in our city. One option is an interior application, or perhaps something as simple as adding a storm window. We can also configure multiple panes of glass, or varying thicknesses, to naturally and scientifically disrupt sound waves. Various STC/OITC ratings are achievable.

Why Install Soundproof Windows?
Homes typically sell better if they have a quiet environment. We have many customers that vastly improved the values of their homes by adding soundproof windows. If you have a noisy approach to your home, but a quiet environment when you enter it, it is impressive to most home buyers. Many customers credit our windows with selling their homes quicker and at a better price. Want to benefit from a quiet, peaceful home? Let our team at WindowFix install sound-reducing windows.


We offer a variety of bird safe glass, including fritted, etched, and UV patterned, which only the birds see the pattern. All of these meet the 2 x 4 rule as set forth by the American Bird Conservancy (ABC).
