Rubber Glazing Seals – Windows / Doors

Rubber Glazing Seals – Product description:

The glazing seal is the rubber seal between the glass / double glazing and the window or door frame. This type of window seal is found on aluminium and old uPVC windows and certain types of doors. Over many years of exposure to sunlight the material hardens and shrinks, leaving gaps at the corners of your windows. This in turn leads to unwanted draughts. It is also very unsightly.

Rubber Glazing Seals – Size Guide

The replacement glazing seal is available in three common thicknesses; 3mm, 4mm and 6mm. If you’re not sure what thickness you need contact us using our contact form and we will send you out a free sample of each thickness to try in your windows.

Trying the replacement glazing seals

  1. With a small flat screwdriver gently pry up the existing glazing seal.
  2. Try each sample seal in the gap where the existing seal was removed. The notched section of the seal faces forwards, the smooth side faces the glass and the narrow edge faces down.
  3. Using your fingers push the seal down into the gap. If there is little or no resistance try the next size up. The seal should take a little bit of effort to push into the gap. If you can’t fit the seal in using your fingers, it is too big. Don’t force in a seal that is too big, as it can break the glass.

When you are happy with the thickness, measure the total length of seal you require. Measure the bottom of the glazed section and add 50mm. Measure one of the sides of the glazed section and add 50mm. Add the two lengths and multiply by 2. This will give you the total length of seal you need.


Bottom measures 800mm, plus 50mm = 850mm.
Side measures 1000mm, plus 50mm = 1050mm
Add both lengths = 1900mm
Multiply by 2 = 3800mm
Total to order = 4 meters

Repeat the process for any other glazed sections. It is always good to overestimate the amount of seal required, to allow for mistakes when cutting
