Universal Greenhouse Glazing Seal - 20 metre rolls (65 1/2 Feet) - 10mm wide 3mm thick single sided self adhesive black UV stable PVC foam (sticks to the aluminium and not the glass) 

This PVC foam is tried and tested and has been used for several years on greenhouses with no deterioration. Please beware of cheaper less dense Polyethylene foam which has not been tested fully for this application. 

4 ROLLS ARE NEEDED TO GLAZE A FULL 8' x 6' GREENHOUSE

 This will work out cheaper than 5 rolls of the narrower 6mm seal elsewhere and works much better. 3mm is the perfect thickness for glazing seal, any thicker and you may have problems fitting your glazing clips, any thinner you could end up with loose glass and draughts.

We have spent a great deal of time experimenting on the best size of seal to replace old or missing seals in used greenhouses. This seal sticks to the glazing bars of the vast majority of greenhouses and replaces rubber as well as non setting mastic seals. The 10mm width ideally fits most glazing bars and will cover the gaps left by the original seal channels. We used to sell the cheaper 6mm wide seal but often found it did not sit very well on a lot of glazing bars.

You will probably only reglaze once so it makes sense to use the best seal and buy from a company that builds greenhouses as their main business, who can advise and help with any questions you have.

The only type of seal we have found it not good for replacing is the thin "U" section type that fits over ridges on glazing bars found Halls, Eden, Juliana Palram, Vitavia and some cheaper greenhouses, please search our shop for the Halls and Eden Seals or ask us for advice, at Elloughton Greenhouses we are more than happy to help.

If you're in any doubt please ask and we'll let you know whether we think this will be suitable for you.
