Sealprem 21 Series foam sealants are fire-rated foam sealants manufactured from closed cell PVC with a very low density & a low force to compress. They are closed-cell structures coated with a pressure-sensitive acrylic adhesive and require 30% compression to create an air seal.
They are available in rolls, logs and gasket form.
Ideal for sealing Facades.
