Measure the frame opening to ensure that there is sufficient room for the product and additional packing
Stud opening
Height=O/A size + adequate clearance
Width=O/A size + adequate clearance
Clearance dimensions vary between manufacturer's products. For adequate clearance refer to window manufacturer's instructions
Frames must be packed plumb, square and not twisted between the openings. Ensure the sill is fully supported; failure to do so may result in sill roll on sliding windows. sills on all windows and doors must be straight and level and should be packed and secured.
Secure aluminum windows by nailing through reveal in brick veneer applications. TImber windows should be secured by back nailing through stud, not face of frame stud. Alternatively, on cavity brick construction use galvanized building lugs located at 450 mm maximum centers.
If it is not possible to backnail, wedges should be installed between the window and the building frame to prevent opening of the frame joints when nailing is carried out.
Keep sashes closed whilst installing frames
Sill bricks should be at least 10mm clear of window frame to allow settlement in brick veneer construction.
Do not stand on the window or doors, or use them as a support for scaffolding, or slide material through the frame. It is important to prevent any damage to windows and doors during construction.
Do not permit weight of eaves or arch bars to bear on any window or door frame. (Windows and doors are not load bearing)
Remove cement mortar and plaster droppings from windows immediately, taking care to avoid scratching glass and, or frames, as permanent damage can result. Immediate attention must be given by washing off with water before material sets.
To ensure the satisfactory long term performance of sliding doors, the sill should be fully supported. Where the sill projects during construction the sill should be fully supported with temporary supports until sill bricks or tiles are installed
