Glass Options

Learn how different coatings, panes and other enhancements affect the performance of your windows.


Single-Pane Glass

Simple and Cost Efficient

Due to lower costs, single-pane windows are great for garages, tool-sheds,  and other non-heated outbuildings. Also, when single-pane windows get broken, they are less expensive to repair as you only need one pane of glass. If energy efficiency is a concern, dual- or triple-pane glass options are a wiser choice.

Single-pane glass units are only available in select Ml window units.

Dual-Pane Glass

The New Standard

Dual-pane windows have become a standard within the window manufacturing world. The two panes of glass, separated by air or gas, work to help insulate the home. At MI, we are able to add enhancements and options to all of our double-pane windows including argon gas enhancement, Low-E coatings, laminated glass, and grids between the glass. All of these options offer significant performance and/or aesthetic improvements over single-pane units.

Triple-Pane Glass

Extreme Energy Efficiency

Triple-pane windows have three layers of glass that help boost energy efficiency. With two available surfaces for Low-E coatings, very little heat is transferred into or out of the home. Additionally, triple-pane glass provides better sound insulation than dual-pane or single-pane windows.

Triple-pane glass is available on select MI window series and configurations.

Spacer Systems

Efficiency Between the Panes

MI offers a variety of glass options engineered to improve the performance of the windows depending on the climate. Spacer systems serve to accommodate stress induced by pressure differences and thermal expansion. They provide a moisture barrier, preventing the passage of water and help keep the window unit from fogging. If enhanced with argon gas, spacer systems help to seal the window, ensuring that the gas won't leak from between the panes over time.


Low-Emissivity Window Coating

Low-E is a microscopic layer of metal that is applied to the inner surface of glass on dual-pane or triple-pane window units. The coating is almost invisible to the naked eye, but provides protection from UV rays that can fade carpets, damage furniture, and even harm your skin and eyes. It also helps to reflect radiant heat from entering the home on a hot day and ensures warm air will stay inside the house on a cold day.


Three Layers of Protection

Low-E3 glass employs three layers of Low-E on the glass surfaces of the window, ensuring maximum energy efficiency and minimum solar heat gain into the home. Low-E3 is a great option for meeting ENERGY STAR® requirements in all climate zones. Low-E3 glass allows more light through the window than traditional tinted glass, which helps maintain visibility while protecting the home.

Argon Gas Enhancement

Invisible Energy Efficiency

Argon is an invisible, non-toxic, and odorless gas that helps improve energy efficiency. Available in dual-pane and triple-pane window units, argon gas minimizes the amount of heat transferred through a window while simultaneously helping to improve sound transmission. Argon also helps reduce the possibility of condensation and frost in all climate, and reduces the transfer of harmful ultra-violet rays into the home.

Laminated Glass

Safety Comfort Fade Protection

Laminated glass is an amazing feature you’ll never see. Similar to a car's windshield, two pieces of glass are bonded to a PVB interlayer. When broken, the glass tends to stick to the interlayer, which is harder to penetrate. Laminated glass also blocks up to 99% of UV rays to keep your furnishings, floors, and other home textiles from fading. A dual-pane window with laminated glass also helps to reduce noise by roughly 50% over a typical double-pane. Laminated glass is also available with argon gas for added energy efficiency.

Impact Glass

Protection from the Elements

Once a home's windows are breached, internal pressure can build up, blowing off the roof and leveling the entire structure. Featuring laminated glass panes, impact glass has passed tests at an AAMA certified testing lab to ensure it meets stringent impact-resistance requirements. After being struck at speeds in excess of 35mph, the weather barrier must remain in place and continue to protect the integrity of the home.

Obscure and Rain Glass

Light and Privacy

Mainly used for decoration, light diffusion, or privacy, obscure glass has a pattern pressed into the glass during the glass making process. Perfect for a first-floor bathroom or a front door side lite, obscure glass works to allow natural light into a space while still protecting your privacy. It can also help to diffuse glare in a direct sunlight setting. Obscure and Rain glass availability varies by region.
