A compound for filling joints and sealing cracks to prevent leakage of water and air.
A maintenance-free material that is placed over another material for added performance or aesthetic appearance.
COMPLETE FRAME CHANGE
A method of installing a replacement window where the older window is completely removed back to the original window opening.
The altering of a gas to a liquid form. Warm air can hold more water vapor that cold air. When warm air cools, its ability to hold water vapor reduces proportionately. Excess moisture then condenses on the warm side of the glass.
A door panel that has not been assembled into a frame.
DOUBLE GLAZED (DUO-PANE)
An insulated glass unit consisting of two panes of glass with a single air space held together by an edge spacer and sealants.
Traditional styled window with a movable upper sash and movable lower sash. Provides excellent ventilation at various levels.
A window designed to meet certain measurements specified by the Alberta Building Code to allow for a person or firefighter to climb in or out in the case of an emergency such as fire.
ENERGY RATING (ER)
Is the value developed by CSA to compare overall thermal performance of a window, based upon its glazing and frame materials. The higher the ER number the better the energy performance (numbers range from 0 to 40).
ENERGY STAR FOR WINDOWS
A federal government program sponsored by Natural Resources Canada. S.I.S. carries Energy Start rated windows.
A horizontal piece of material that runs along the roof line and meets up with the soffit on the underside.
FIXED WINDOW (SEE ALSO: PICTURE WINDOW)
Fixed windows are also non-operational windows, designed to let in light and add expansive views. The difference between Fixed and Picture windows lies in the frame size.

The upright or vertical members of window and door frames.
Two or more sheets of glass with an inner layer of transparent plastic to which the glass adheres if broken. Used for enhanced safety, security and sound reduction.
A glass type consisting of a low-emissivity coating on one side. Used to reduce heat loss or heat gain dependent upon the Low-E selection. Performance of Low-E units is often enhanced with the use of non-toxic gases such as argon. Low-E glasses are recognized for their significant contribution to reduction of energy costs.
PICTURE WINDOW OR DIRECT SET (SEE ALSO: FIXED WINDOW)
A stationary non-opening window consisting of a common frame with an insulating glass unit.
Resistance to thermal transfer or heat flow. A higher R-value indicates greater insulating properties. R-value is the inverse of the materials U-value.
Opening in a wall which a window or door is installed.
The inner frame which holds the glass units in a fixed or operating window.
SDL (SIMULATED DIVIDED LITE)
A decorative bar mounted on the exterior and interior of a sealed unit that produces the visual affect of dividing the glass into smaller equal portions. A shadow bar option utilizing metal grilles inside the glass unit can further enhance the appearance towards a true divided glazed unit.
