About us

Castelein Sealants

A high level of in-house production has enabled Castelein Sealants in Kapellen to grow considerably in a very short period of time. We launch very competitive and high quality products directly on the market.

Our intensive cooperation with institutes such as Butgb, the University of Ghent, Efectis (fire resistant), Rosenheim and other external test centres enables us to develop high performing products and provide them with the necessary certificates.

Sealings in façades and façade construction (airtight foils, EPDM, foams and adhesive tapes) represent the main part of our turnover. In addition, we also strongly invest in insulating support systems to support the joinery and in acoustic and vibration-damping punched sealing systems.
