Greenhouse rubber glazing gasket is an essential part of many aluminium greenhouses and may need replacing periodically.

Aluminuim and glass do not sit well together so you need this flexible gasket at the point of contact between these two unforgiving surfaces. The gasket allows for a little 'give' between the glass and the aluminum which is particularly needed when we get strong winds and the greenhouse flexes.

It will be part of the original kit in a new greenhouse but if you have inherited an old greenhouse, or your existing greenhouse is old, you will need to replace the original gasket. This gasket is ideal for Halls Greenhouses and also the now discontinued AGL greenhouse range as well as many other greenhouses. This 'n' profile gasket has support flanges for the glass on either side.

It is supplied in an individual pack of 18 metres long. Three packs would be required for a complete set for a 6ft x 6ft greenhouse in most instances. If you are looking for an alternative we also sell a Universal Glazing Gasket.

How to Fit Greenhouse Gasket

Fitting them is easy once you have decided which type of aluminium greenhouse bars you have. Some have a channel into which you push the gasket which stands proud allowing the glass to sit directly onto the gasket. Other models allow you to slip the 'n' profile over the ridge allowing the glass to go directly onto the ridge protected by the gasket.

Good quality product. Only complaint was that there was not enough in one pack to do our greenhouse and far too much to warrant buying anothe rpack

greenhouse rubber seals

The only problem that I found was that the strip bundle was secured by using the strip to tie a knot around the bundle. This section had to be cut off as the sections were damaged beyond my repair skills
