Windows Windows are typically composed of a vinyl frame or a wood frame covered by a metal skin on the exterior. The frames of vinyl windows and the exterior metal on a metal-clad window are virtually maintenance free. Interior wood finishes should be maintained as per the manufacturer’s instructions. Weatherstripping between the fixed and opening parts of a window should be checked regularly and replaced when necessary. Clean windows yearly during moderate temperatures like the spring or fall using a solution of soap and warm water with a soft cloth. Do no use abrasive cleaners, razors or stiff brushes. Clean and lubricate hardware and tracks as recommended by the manufacturer Weatherstripping provides a flexible seal around windows to prevent unwanted air from moving in or out of your home. On windows that open outwards with a crank (casement or awning windows), the weatherstripping is usually a compressible, moulded strip of foam or rubber set against the frame towards the outside. The opening part of the window rests against the weatherstripping when the door or window is closed, forming an air and water seal. On sliding windows, the weatherstripping is usually a flexible v-strip or a brush/ bristle type and is placed between the track and the moveable window and at the point where the fixed and the sliding window meet. Felt-type weatherstripping should be avoided as it can gather at one edge of the window over time and create an air gap. Weatherstripping that has lost its resiliency will not provide an effective seal and should be replaced. Check your windows each fall and reposition or replace this weatherstripping as required. Weatherstripping will lose its flexibility if painted. What is weatherstripping and how do I maintain it? 32 ANHWP.COM • ALBERTA NEW HOME WARRANTY PROGRAM
