Insulated Glass is a specialty type of tempered glass that resists thermal and chemical temperature. Insulated glass or “double-pane” glass can be used for both household purpose and business construction. It is compulsory by architecture codes in many ranges as a obligatory energy maintenance quota. Single pane glass has essentially NO insulating value. Insulated Glass (IG) units are air tight sealed combinations of two or more planes of glass separated by a dry airspace. Insulated glass units improve thermal performance, significantly reducing heating and air conditioning costs. Insulated glass units also reduce interior condensation in cold climates.
3/4″ and with airspace thicknesses ranging from 3/16″ to 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.
PROSPERITY OF INSULATED GLASS
There are many advantages of using insulated glass window and door products in your residence and work place. Not only lowering one’s energy costs, insulated glass units also are effective in reducing unwanted sound transmission.
- Insulated Glass can resists thermal and chemical heat.
- Insulated glass is a high protection tempered glass.
- This is used to reduces heat of daylight in summer time. The glass wall, furniture etc. absorbed heat.
- By using window and door products with a low solar heat gain coefficient, the solar radiation coming into one’s home is decreased.
- Can be applied in both residential and commercial purpose.
- It is also a decorating glass.
- furthermore, during the winter seasons, insulated products create warmer domestic glass surfaces, reducing frost and contraction from forming.
- Window glass selection influences the type and intensity of ultraviolet (UV) rays, which causes fading and degradation.
Key Performance Requirements
- Thermal Insulation: The principal logic for using IGUs is to cut down on thermal heat coming from outside. Thermal insulation initially depends upon the dryness of the air inside the IGU, as well as the quality of the hermetic seal.
- Working Principle: It works on the basis of reducing navigation and transmission heat transfer across the unit.
Dry air is a poor conductor of heat. Due to the air-gap, the conducted heat through glass is reduced significantly as it reaches the second pane.
- Structural Strength: Insulated Glass Units(IGU) are consistently exceedingly heavy. For example a Additionally in certain applications like structural glazing, IGUs often act as structural members of the building.
It is paramount that the strength (direct and shear strength) of IGUs is maintained. This strength is primarily a function of the type of spacers, number of spacer joints, type of spacer joints (corner joints Vs side joints), type & quality of the secondary sealant, and adequate quantity of the secondary sealant .
IGU’s provide better protection against fogging than a single pane of glass. However, IGU’s made without proper quality control, poor desiccant filling practices, inadequate quantities or incorrect type of desiccants, or a poor hermetic seal are more prone to fogging.
