Insulated Glass Unit
Insulated glass or "double-pane" glass can be found in both residential and business construction. It is required by building codes in many areas as a mandatory energy conservation measure. And it really makes sense because single pane glass has virtually NO insulating value. Bear Glass Insulating Glass (IG) units are hermetically sealed combinations of two or more lites of glass separated by a dry airspace. Insulated glass units improve thermal performance, significantly reducing heating and air conditioning costs. IG units also reduce interior condensation in cold climates.
3/4" and with airspace thicknesses ranging from 3/16" to 7/8" having standard spacer colors of clear, bronze and black anodized, and mill finish aluminum. Maximum sizes for insulated glass units are determined by a number of considerations including thickness, weight, aspect ratio, application and load requirements.
There are many benefits of utilizing insulated window and door products in your home. They not only lower one's energy costs, but also 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.
