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.
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.
Key Performance Requirements
- The primary reason for using IGUs is to cut down on thermal heat coming from outside. Thermal insulation primarily depends upon the dryness of the air inside the IGU, as well as the quality of the hermetic seal.
- IGUs work on the principle of reducing conduction and convection heat transfer across the unit.
- Insulated Glass Units(IGU) are typically extremely heavy. For example a Additionally in certain applications like structural glazing, IGUs often act as structural members of the building.
