Insulated (Double / Triple) Glass Unit (IGU)

IGUs’ are basically multiple layered glass panes that have very dry air or inert gas between the glass panes. The glass panes are hermetically sealed.

Any use of two thick nesses of glass tempered or laminated for safety, separated by an air space, within an opening, to improve insulation against heat transfer and/or sound transmission. In factory-made double-glazing units the air between the glass sheets is thoroughly dried and the space is sealed airtight, eliminating possible condensation and providing superior insulating properties.

The most critical component of an IGU is the desiccant, which removes humidity from the cavity to prevent condensation within the IGU.

BENEFITS:

There are many benefits of utilizing insulated window and door products in your home. They not only lower one’s energy costs, but also make homes cozier by improving comfort, decreasing condensation, as well as, diminish the effects of fading. Insulated units are also highly effective in reducing unwanted sound transmission.

In the summer, heat is transmitted through the glass and is absorbed by the walls, furniture, floors, etc. By using window and door products with a low solar heat gain coefficient, the solar radiation coming into one’s home is decreased. This reduces the amount of heat entering the home, thereby improving one’s homes’ comfort level and lessening the amount of energy needed for cooling during warm weather months.
Moreover, during the cooler seasons, insulated products create warmer interior glass surfaces, reducing frost and condensation from forming.

Another benefit is that during daylight hours, sunlight is transmitted through the glass and is absorbed by the walls, furniture and flooring. Many materials, such as carpet, curtains, upholstery, artwork and wood may fade upon exposure to sunlight. Window glass selection influences the type and intensity of ultraviolet (UV) rays, which causes fading and degradation.
