Make sure the frame can open and close easily when the double-glazing unit that is sealed is installed. You can alter the fit as needed by removing or adding packing. For example, if the frame is a sliding bifold door seal replacement you might need to add extra packers at the top of the hinge's side and in the opposite corners to stop the sash from getting caught or shaking when it opens.

Finally, clean the frame and remove any old glaze tape or sealant as required. Examine any imperfections and make minor repairs with wood filler or sanding if needed.

Desiccants also absorb moisture from the air, preventing mould and condensation in the frame. The spacer bar is constructed of aluminium and is an essential component of the insulation system. Aluminium not only impedes heat transfer but also keeps the edge warm of the window insulated to avoid condensation.

Be sure to check your work
