IEG’s Window Insert is a clear, double paned polycarbonate window insert with an air tight gasket that fits snugly into the interior of an existing window opening.
It effectively creates two insulating air spaces that drastically reduce heat loss, while increasing comfort levels by keeping conditioned air separated from existing windows. It essentially makes a single pane window a triple pane.
It insulates the opening by stopping the permeating temperatures that glass cannot. The window insert slows the infiltration of solar heat gain and blocks 99% of the ultra violet (UV) radiation. When applied to a single pane window, it can improve the U-Factor by as much as 120% and the SHGC by 10%. It stops 99% of the air infiltration (drafty windows). It also has sound remediation qualities and can reduce noise by as much as 7 to 10 decibels.
The window insert costs 50-70% less than a replacement window with the same insulation value. Because of its unique gasket system, installation is simple, quick and with none of the mess and inconvenience.
IEG’s Window Insert helps your HVAC system work less to maintain the desired temperatures within your building. It allows more efficient climate control by eliminating the hot and cold air from entering or escaping.
The unique gasket around the perimeter is made of EPDM rubber and is resistant to extreme heat and cold, steam, ozone and weather conditions. It has an 85% memory retention. Because it is open and breathable, it reduces condensation. The stock color of the gasket is white but can be matched to almost any color through the extrusion process.
The polycarbonate has optical clarity and comes in various thicknesses depending on orientation and size. Stock thicknesses are .060, .118 and .150 but a variety of thicknesses are available.
The applications of IEG’s Window Insert is not limited to single windows alone. It can be applied to large window facings such as store fronts, insulating the entire “window wall”.
IEG’s Window Insert is an affordable, convenient, “super efficient” way to insulate your windows. Installation is simple, quick and does not require demolition or construction. IEG’s Window Insert will improve the comfort level of any office or building, reduce its energy consumption and save money.
