Castelein Sealants

Self-adhesive foils for the construction industry to be used as water barrier and/or airtight finish around windows.

Castelein Sealants develops, produces and distributes air and watertight sealing products for the façade and window sector. The company produces made-to-measure sealants and delivers them just-in-time, which optimizes the construction process and greatly reduces site waste.

Since its incorporation in Belgium, the company has grown strongly in the Netherlands and Luxembourg in recent years, partly since the entry of Akiles. The strengthened cooperation between Gimv, Akiles and management is part of a new Europe growth phase, in which the company initially wishes to invest further to accelerate its current growth in France.
