Expert Window Installers in Richmond Hill, ON

In general, two thicknesses of glass separated by an air space within an opening to improve insulation against heat transfer and/or sound transmission. In factory-made double glazing units, the air between the glass sheets is replaced by Argon or Krypton gas or mixture of them and the space is sealed airtight, eliminating possible condensation and providing superior insulating properties.

Two or more sheets of glass with an inner layer of transparent plastic to which the glass adheres if broken. Used for safety glazing and sound reduction.

Microscopically thin, virtually invisible, metal or metallic oxide layers deposited on a window or skylight glazing surface primarily to reduce the U-factor by suppressing radiative heat flow. A typical type of low-E coating is transparent to the solar spectrum (visible light and short-wave infrared radiation) and reflective of long-wave infrared radiation. In other word Low-E stands for low-emissivity. Emissivity is a measure of how much a glass surface transfers radiant heat. Glasses with this type of coating called Low e Glass.

The percentage of moisture in the air in relationship to the amount of moisture the air could hold at that given temperature. At 100 percent relative humidity, moisture condenses and falls as rain.

A strip of resilient material such as rubber or soft PVC for covering the joint between the window sash and frame or door gaps in order to reduce air leaks and prevent water from entering the structure.
