Installation Practices
A clear, practical guide that allows us to install our high quality uPVC and aluminium windows with ease.Before starting, carefully check the new frame measurements are correct against the survey size and the actual aperture sizes. Prepare the external cill by cutting it to size, this can be a straight cut or rebated if being fitted with projecting horns. Carefully silicone along the cill up-stand and at both ends, this is to prevent water and air leaks occurring between the cill, frame and surroundings. The frame is ready to be secured in place, fixings should be located approximately 150 in from each corner and then spaced at 600mm intervals, do not fix within 150mm of any mullions or transoms. Using suitable uPVC fixings secure through the frame into the building. It is important to use plastic packers between the frame and the building at all fixings points to ensure that the frame is not distorted when tightening the screws. Once in position, clean away any dust or dirt before removing the internal glazing beads, ensure that you don’t mix these up as they need to go back in the same positions on the frame.
