System SHARK®
and seals in TPE

The SHARK ® system consists of two sealing fins that are inserted into the end of the TPE seal. The goal is to maximise the performance of Caiframe design windows in terms of air and water tightness.

The seals in TPE (thermoplastic foam) are made of a non-deformable material with a very high elasticity that provides excellent guarantees of tightness over time to thanks to its known stability properties, confirmed even at very high and very low temperatures.
