The energy efficient window industry offers an array of different types of glass, each with its unique benefits and properties to get the most out of the glass. When the appropriate glass is used in combination with a supportive and energy efficient window frame, the window's thermal efficiency is enhanced. Factors such as geographical location, orientation of the house and each wall, tinting, space between the panes are only a fraction of areas that today's glass and glazing technology can help improve.
Choosing Double vs Triple Glazed Windows
Double glazing is a Canadian standard for fenestration in which the sealed unit consists of two panes of glass, each ¾" thick. Triple glazing consists of three panes of glass, making a substantial improvement in insulation capabilities. Both double and triple glazed windows can be thermally enhanced by adding gases between the panes of glass, such as argon or krypton. Triple pane windows are the ultimate solution for saving energy and reducing costs over time.

Low Emissivity Glass (Low E/LoE)
Low E is a thin and sensitive film made out of metal and is used on glass to help reduce heat radiation. The glass that has this film on it is referred to as Low E or LoE glass. The film has a slight tint and is hardly noticed, yet it has great ability to keep UV rays out while gaining solar heat. Low E glass can either increase the SHGC, or lower the U value, depending on how it is used. There are two main categories of low emissivity glass: soft coat and hard coat glass.
Soft coat glass – When using soft coat glass, the glass reflects the heat and the UV rays. Soft coat glass is used on the west, north or east sides of a house to help reflect the UV rays. This type of glass has the ability to reflect more heat back to the source and will have a higher R Value than hard coat glass.
Hard coat glass - Used for solar heat gain, and is used for windows or doors that are facing the south side of the house in order to benefit from all solar heat gain possible. Hard coat low-e will usually achieve a lower U value than soft coat low e because more sunlight penetrates through the glass. Hard coat low e is best used for homes that rely on heating from the sun.
Heat Mirror Films
Heat mirror film is used to increase energy efficiency by placing a film between two panes of glass in a double glazed sealed unit. Depending on the type of film used, heat mirror film can allow for high light transmittance and maximize thermal efficiency. Two of the most common types of heat mirror film are TC88 and SC75, which both perform well and are used according to the demands of the project.Learn more about heat film technology
