Good surveying is essential to ensure a trouble free successful installation, also to avoid costly remakes caused by incorrect measuring.
When surveying it is the surveyor’s responsibility to determine that the structural openings and surrounding areas are in a state of good repair and provide the correct dimensions for manufacture.
It is not possible to provide full comprehensive surveying instruction to cover every eventuality, the following basic notes are for on-site surveying guidelines:
1. On arrival, before removing any existing window frames, check that the replacement frames size is the same as the existing window frames. When checking the sizes, ensure that the new frame has a 5mm expansion gap around the perimeter.
2. Once you’re sure your measurements are correct, proceed to remove the old window frames.
3. Run a sharp blade around the inside perimeter of the window to break the bond between frame and the plaster. This will also minimise the damage to any interior decoration.
4. Remove as much glazing as possible, this will help to reduce the weight and allow easier handling.
1. Remove any packaging from the new frame and screw the cill onto the bottom of the frame. Make sure you select a screw that will not penetrate the inner skin of the frame.
2. Be sure to seal the ends of cill and frame assembly to prevent moisture from tracking along the cill and into the brickwork.
3. Carefully position the new frame into the aperture. Centralise it and insert packers underneath to level it and maintain the 5mm expansion gap.
4. Check that frame is both level and plumb, then drill fixing holes into the frame sides. These should be drilled approximately 150mm from the top and bottom corners and approximately 600mm in between (a minimum of 2 fixings per side)
1. Commence glazing the frame, ensuring that appropriate glazing platforms are fitted around each aperture. These centralise the glass and allow free passage of water to run to the drainage slots.
2. Place each pane into position, noting that where opening casements are hinged from the sides they should have the glass packed at diagonally opposing corners to hold the casement square.
3. As each pane is positioned, the beading can be installed using a nylon mallet and tapped securely into place. It is recommended that horizontal beads are installed first and that the beads are refitted to their original position.
1. Clean the external surfaces to remove the dirt and grit.
2. Apply a strip of masking tape to the frame perimeter. Apply a smooth bead of silicone sealant between the frame and brick work. Before the sealant sets, remove the making tape to create a neat finish.
3. It is important to remember to seal the below the external cill.
4. Once the area has been cleaned of all debris, step back and admire your newly fitted Eurocell window.
