Safe and Efficient Egress Windows for Your Home in Calgary

Egress windows are meant for escape in case of fire or other emergency and are required by the National Building Code of Canada.

 

Windows designated as egress windows must be large enough, placed correctly, and easy to open without special tools. These windows are occasionally paired with ladders or steps for an easy escape from basements and upper floors.

RVW Ltd will be pleased to help you know where you should install egress windows and to advise you as to what sort of window to use size requirements, and issues regarding installation.

What Windows Qualify as Egress Windows?

There are a specific size and other requirements for egress windows. The International Residential Code has four requirements for egress windows.

– Twenty-inch minimum opening width

– Twenty-four-inch minimum opening height

– Five and seven-tenths square feet opening free area

Forty-four-inch maximum height above the floor of the window sill.

The point of these requirements is that children will be able to get up and through the window in case of a fire and that adults will fit through the opening.

Remember that the requirements have to do with the clear space in a window opening and not the size of the frame or the glass panel. It refers to space through which you and your children must crawl to get to safety!

You Must Be Able to Open an Egress Window without Tools

During life and death, an emergency is not the time to be looking for keys for a lock or a screwdriver, plyers, or spanner. Thus a requirement for egress windows is that they can be opened in a hurry without the use of special keys or tools.

If a basement or main floor window is fitted with a security screen or bars, they must have must also be easy to open without having to go looking for tools!

The Total Open Area is Important for an Egress Window

The minimum dimensions of an egress window are twenty inches for the width and twenty-four for the height. However, a twenty by twenty-four-inch opening only has an area of three and three-tenths square feet!

The opening has to have a cross-sectional area of five and seven-tenths square feet.
