PRIMO groove welding seals are used to re-establish seals in primarily wooden windows and doors of older date.

The welding method was standard, in the past and today there are sealing gaskets that are much easier mounted with improved long-lasting results, especially our latest gasket with cord 6307. However, in some situations the groove welding seal is the only option for a renewal.

We recommend that you consider the possibility of switching to the newer alternative, to save you time and effort without compromising the quality of the result.
PRIMO has a diverse range of PVC-free gaskets made of TPE that are durable as seal and suitable for outdoor use. PRIMO can here, provide solutions for any purpose.


When installing welding mouldings, the profile is cut at 45 degrees and welded together. Then, the moulding is installed in the corner and pressed into the groove. Possibly using our in-rollers that you can find under accessories for gasket clamp profiles.

Be aware that the seals are not completely pressed together when the door or window is closed as over time, they will lose their ability to recoil and seal.
