Safe and durable
Resistant to UV radiation
Withstands extreme driving rain
Is open to diffusion
Adjusts to large temperature differences

Flexibility

Expands to find its own level and can seal against uneven surfaces, its permanent elasticity compensates for temperature-related movements of the components as well as tolerances due to construction and materials. Unlike some foams or sealants, it will not crack or split, retaining a permanent seal.

Installation

It can be applied in a single operation regardless of the weather and protects against moisture, both from the outside and the inside. It is quick and virtually foolproof to install as it has no “inside” or “outside”. It has high adhesive strength and expands more slowly than other foams so even on a hot day, it gives comfortable working time to the installer.

Finish

Once installed, you’re left with a clean black border between the frame and surrounding materials, enhancing the appearance of doors and windows.
