Universal Greenhouse Glazing Seal – 25 metre rolls – 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. 3 ROLLS ARE NEEDED TO GLAZE A FULL 8′ x 6′ GREENHOUSE. 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. 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. 1 long 25 metre roll will suffice for around 20 x 24″ x 24″ glass sheets, 3 rolls will cover a full 8′ x 6′ greenhouse. 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 on some of the cheaper greenhouses. The last photograph shows this type, if your bars use this type of seal unfortunately we cannot help you currently. If you’re in any doubt please ask and we’ll let you know whether we think this will be suitable for you.
