Felt Collars – PHS Airtight Grommets

£4.32£30.48 inc. vat (RRP)


Airtight Grommets offer a permanent strain relief and a perfect sealing of all installation passages of your house.

Poorly finished penetrations in the airtight membrane and the vapor control layer can lead to rapid damage of the adjoining building elements and an unnecessary loss of heat and energy via the building envelope. Airtight Grommets not only reduce the heat loss of your house, but also save heat energy and prevent damage due to humidity.

What makes Airtight Grommets so special?
The various laminations and diameters allow you to seal installation passages individually according to your special needs. The felt collars consist of flexible EPDM-rubber bonded with a self-adhesive pad, carrier material (base) Tyvek with an age resistent layer of acrylate adhesive.

Important notes

  • The sleeves are delivered talc powdered. If there is insufficient gliding ability, please use the provided talc powder, in order to rework the inner sleeve or the cable.
  • The self-adhesive acrylate sleeves are safe and permanently moisture-proof. They are also suitable for gas barriers. Adhesive surfaces include wood fibreboards, OSB-boards, vapour barriers or vapour locks and sarking membrane.
  • Finally – you should pre-treat some surfaces with Gerband 6300 Airtight Primer. The surfaces must be dust-free and free of grease as well as dry and stable.
