PRIMO groove welding seals are used when replacing seals in windows and doors that have lost their breath and no longer have the desired effect. Seals, especially of older types, perish over time and this results in poor insulation, which will show as an increase in your heating bill.

The cord of the welding seal ensures that you have a solid corner assembly.

PRIMO has a wide selection of different sealing gasket, where you will find a gasket for any purpose.
The majority of PRIMO gaskets are manufactured in TPE, which is a PVC-free material that is suitable for use in as out. TPE has a long durability and helps to maintain a healthy indoor climate.


When installing the Sash Rebate seal, the profile shall be cut at 45 degrees without over cut of the cord that is inside the seal.
You may use our trim shears for this purpose – you can find them under accessories for gaskets.
Then, the moulding is installed in the corner and pressed into the groove.

Most of our Sash Rebate seals are made with a hard back that significantly simplifies the installation.

Be aware that the seals are not completely pressed together when the door or window is closed as over time, they will lose their flexibility and thus impair sealability.
