Insulated Glass

1.Description of Insulated Glass

  Insulated glaszing glass is made of two or more pieces of glass glazing sheets which might be low e or reflective glass or normal float colored glass and use sealant gumming and aluminum spacers which was filled with desiccant together. Insulated glass/ Hollow glass/IGU/Double glazing glass with the perimeter of the spacer that gets in contact with the glass is properly sealed with primary and secondary sealants to ensure it with air/argon tight.
 

Insulated glass not only could save energy power, also it can get sound insulation. This kind of IGU can enhance a window's thermal insulation up to 3 times resulting in reduction of energy consumption of up to 75% compared to a single glazed unit.

3.Benefits of Insulated Glass

·Its excellent efficiency in solar heat insulation, greatly reduces cooling loads.

·The dry air inside the enclosure renders the surface free from misting

·More excellentefficiency will be if fill in argon or other inert gases

4.Terminology of Insulated Glass

Argon Gas: An invisible non toxic gas used in insulating units to enhance the units insulating performance (u-value). 

Bite: The dimension by which the framing system overlaps the edge of the glazing infill. 

Butyl: Shortened term for polyisobutylene. The primary seal of an insulating unit and key component in restricting moisture vapor transmission. 

Capillary Tube: A small tube factory-placed into the air spacer of an insulating unit used for balancing interior and exterior pressures during transportation over higher elevations i.e. mountain ranges or air transport. 

Desiccant: Small extremely porous beads used to absorb moisture in the sealed air spacer of an insulating unit. 

Heat Transfer Methods: Heat transfers from one place to another via convection conduction or radiation. Convection occurs from the upward movement of warm light air currents. Conduction occurs when energy passes from one object to another. Radiation occurs when heat is sent through space and is capable of traveling to a distant object where it can be reflected absorbed or transmitted. 

Shading Coefficient: Shading coefficient is the ratio of solar heat gain through a specific type of glass that is relative to the solar heat gain through a 1/8"" (3mm) ply of clear glass under identical conditions. As the shading coefficient number decreases heat gain is reduced which means a better performing product. 

U-Value: A measure of heat gain or heat loss through glass due to the thermal conductance and the difference in indoor and outdoor temperatures. As the u-value decreases, so does the amount of heat that is transferred through the glazing material. The lower the u-value the more restrictive the fenestration product is to heat transfer; reciprocal of r-value.
