Lock Up Windows Window Installation
Pre-installation of Windows
Windows should be stored in a clean, dry area away from lime, paint, acid, and must be protected from building materials and loose debris such as wet plaster, mortar, paint and welding splatter.
Store in a dry location, under cover where possible, to protect against damage
Carry window in a vertical position with sashes locked
Do not rack frames out of square
Prevent exposure to moisture particularly pooling and ponding
Do not remove any bands (if fitted) from double hung windows until after installation
Do not remove corner bracing (if fitted) until after installation
Factors That Contribute to Installation Problems
Installation problems such as incorrect fittings or the omission of flashings, smothered or missing weep holes, or the loss of continuity in the water barrier are the prime cause of leaks in the window assemblies.
Severity of exposure to wind is the most important factor in the specification and installation of windows and doors in openings. Components and installation practices acceptable in sheltered situations may quickly fail when exposed to the full force of the wind and rain.
Follow the windows manufacturer's installation specification for the appropriate terrain category and height of building; many manufactures' brochures provide information for sheltered buildings no more than one story high.
Handle and stack frames carefully on the site. Stand them upright on their sills (bottom of the window as installed), raised off the ground on pieces of timber or bricks. Stand them against a flat, vertical surface such as a shed and tie firmly in position.
Do not lean windows against a tree or post as they can be subject to permanent damage until installed into the building envolpe. I the site is abre, lat frames flat on top of each other with weight evenly distributed to avoide buckling and distortion.
