New Frame Preparation

When preparing the new frame, the following points should be followed:-

If you are using fixing brackets, these should be firmly attached to the outer frame, starting at no less than 150mm from the corners and at no more than 600mm centres.

If you are to screw through the main outer frame into the structure, then the glass in the appropriate fixed light must be removed. If the window is too heavy for convenient handling, the glass units may have to be removed.

Choosing one of the longest beads first, push a sharp chisel or rigid putty knife into the bead/ frame joint at approximately the centre point. Apply force to lift the bead up and out. Starting at the end of the next bead, the remainder can now easily be removed. Make a note of the positions of each bead to ensure correct poitioning later.

Carefully remove the glass unit, taking care not to disturb the packers. Store any glass you have removed safely away from where you are working.

With sash windows it may be more convenient to remove the sash or sashes. To remove the sash from the frame, open the sash to its full extent and keep fully supported. Carefully remove the screws from the friction stays on either the sash or frame. Refitting is the reverse of this procedure. It is important to ensure that the screws locate into the original fixing holes. Finally, check for squareness of vent in frame aperture.

If a cill is required and has been supplied separately from the window, then it must now be attached. If the cill is to be fixed to the window frame with screws, always screw from the underside of the cill into the frame. It is important that fixings do not penetrate drainage channels.
