How do you install Pyroplex Intumescent Fire and Cold Smoke Seals?:

Temperatures should be between 5°C and 40°C

Locate the seal in the central channel of the door leaf or frame.

Create a suitably sized groove to fit your size of intumescent seal.

Ensure that the rebate is clean and free from dust.

Remove the adhesive backing liner from the seal, then push fit it into the groove.

To seal the bottom of the door we suggest using our Surface-Mounted acoustic drop down Seals or Acoustic & Smoke Perimeter Seals.
