uPVC Double Glazing Wedge Gasket Seal


Rubber wedge gasket glazing seal is mainly used to hold your double glazed glass unit securely in place. When installed externally on windows it also acts as a weather seal, locking out water and draughts. You won't require any adhesive or tools to install the double glazing wedge gasket, as it simply pushes in to the gap around the double glazed unit.

How do you stop a draught from a window?

The main way to stop a draught coming through your window is to install new rubber gasket seal. Overtime your old rubber seal will flatten, become hard or brittle and shrink. This will severely reduce its ability to create a quality seal. Installing a new rubber gasket seal will ensure you have a high quality seal which will stop draughts coming through your windows and doors.

How to order the correct gasket seal

The easiest and most accurate way to select the correct rubber gasket seal is buy using our sample pack. The sample pack we supply contains a short piece (approx. 100mm) of each gasket we have on offer. They will all be individually labelled with the corresponding code making them easy to identify. 

You can then test each gasket in your window or door to ensure you're selecting the best performing gasket. Please note all sample packs come in black only.
