Description
Norfinch Glass offers Insulated Glass Units for both residential and commercial applications all across toronto, the GTA and surrounding area.
Understanding Insulating Glass Units
Insulating glass units, or IGUs, are designed to keep homes warmer in the winter and cooler in the summer.
An insulating glass unit commonly consists of two (sometimes more) panes of glass separated by a spacer material and sealed together at the perimeter. The insulating airspace is filled with air or a noble gas, such as argon or krypton inside. Each glass pane has two surfaces, so typical double-paned IGUs have four surfaces.
Components of Insulated Glass Unit (IGU)
The major components of insulated glass are:
- Desiccant: It is a drying agent used in IG to remove humidity and moisture present in between the glass panes. The most commonly used desiccants in insulated glass are silica and zeolites.
- Spacer: The spacer determines the width of the gap between the two panes of glass in an insulated glass unit (IGU). It provides a fixed gap between two layers of glass and is made of aluminum or thermoplastic material. Desiccant rests between the spacers.
- Sealants: Sealants are applied on IGU to make sure the insulated air doesn’t escape from the cavity. The most common sealant used in IGU units is butyl sealant.
- Cavity: The insulation characteristics of IG are due to the air or gas-filled cavity. Air is commonly used in the cavity of double glazing glass. Argos, krypton, or other gases that slow the transfer of heat are also used to fill the cavity.
