Glass options


Learn what the difference is between single, double, and triple-glazed glass, and options available with that glass, such as Low-e, Solar-Gain, Tinted coatings, as well as Argon and Krypton gas fillings.



Compareed to other glazings (which can be simply thought of as panes of glass) single-glazed glass units allow for the highest heat transfer (gain and loss) and also provides the greatest amount of daylight transmission.

aluminium frame


Two layers of glass separated by a gap of air (sometimes Argon or Krypton see below) Typically can cut heat loss in half due to the insulating pocked of air.

wood frame


Three layers of glass with two pockets of air. Provides the highest level of themal insulatoin. This insultive property can be compounded upon by using argon or krypton gas layers.

vinyl frame




A microscopically thin, metal or metallic oxide coating used to reduce solar heat gain without reducing the amount of visible light that flows through the glass. Different variations of Low-E coatings may allow more or less solar heat through (often optimized by region) and higher solar heat gain blocking Low-E will often appear slightly more tinted and block a greater percentage of visible light.


Argon Gas:

An inert gas placed between panes in double or triple glazed windows that improves the insulating properties of a window. Since the gas is a more viscous or slow-moving than the normal air filled in between the gaps the heat transferred between the panes is decreased. Keeping your home better insulated.

Gas Filling

Krypton Gas:

Working along the same principal as Argon gas. Krypton gas has been shown to perform even better than Argon. However it is often a scarce commodity in the window manufacturing market and so just like the insulating properties the price will also rise.
