Conserving energy is a priority for you, and for us. We provide a wide variety of high performance glass options that will help increase your home’s energy efficiency.
- Low-E Argon – Saves on energy. Increased thermal performance by combining a Low-E coating, argon gas and a warm edge spacer. The Low-E coating helps to reflect your home’s heat back inside and the argon gas is a great insulator.
- Energlas® – The standard in glass performance. Our most popular glazing option dramatically reduces heat loss and infiltration of harmful UV rays. It uses a high performance warm edge spacer, one pane of Low-E coated glass and one cavity filled with argon gas.
- Energlas Plus® – The ultimate in high performance & energy efficiency. Technology at its best. It is an ultra high performance energy efficient triple glazed system using warm edge Super Spacer, two panes of Low-E coated glass, and two cavities filled with argon or krypton gas.
- High Solar Gain (HSG) Glass comes standard with all three options to allow the sun’s warmth in your home year round.
- Low Solar Gain (LSG) Glass is best for keeping the cold out and is optimal for north facing windows.
Other Glass Options*
- Tempered – Tempered glass is a type ofsafety glass, it undergoes heat treatment to increase its strength. If it does break it shatters into small pieces that are less likely to cause harm.
- Sound Reducing Laminated – Sound Reducing Laminated glassis another type ofsafety glass that reduces outdoor noise by up to 50%. The glass is held together by an interlayer to improve its safety
- Architectural Glass – We offer a wide variety of glass options to fit projects of any size and makeup. Unique offerings include specialty privacy glass, float glass, solar control glass, and safety glass

Glass Performance Ratings
- Energy Rating (ER) – The higher the better. A measure of energy efficiency for a window or door. This number is calculated by combining heat loss and air leakage loss with gains from solar heat. The higher the number the better.
- U-Factor – The lower the better. Indicates the rate of heat loss through a window or door. The lower the U-Factor, the slower heat transfers from a warm area to a cold area, and the better the unit insulates. U-Factor is the inverse of the R value.
- R-Value – The higher the better. Indicates the thermal resistance of a window or door and is the inverse of U-Factor. There are two R-Values referenced in the industry; Center of Glass R-Value and whole Window R-Value.
- Solar Heat Gain Coefficient (SHGC) A measure of the amount of solar radiation that enters a building through a window as heat gain. It is important to remember that an LSG unit will block unwanted sun (in summer months), but it will also block wanted sun (in winter months). Condensation Resistance Measure of how well a product resists the formation of interior condensation. The higher the number the more effective the product is at preventing condensation.
- Insulated Glazed Unit (IGU) – Made up of two or three glass panes separated by chambers of air or an inert gas. This results in decreased heat transfer compared to single pane units.
- Glazing – A pane of glass set or made to be set in frames (Triple glazed is three panes of glass to improve energy rating).
- Low Emissivity (Low-E) Coating – A thin, virtually invisible metallic layer that reflects heat back to the same side of the glass it originated from. This increases a structure’s ability to retain heat.
- Warm Edge Spacer System – Raises the temperature of the glass near the frame, decreasing heat loss. Also functions to remove any moisture between the panes of glass. We offer three types of spaces: Intercept®, Ultra®, and SuperSpacer®
