Interalu attracts growth capital from Waterland to accelerate its international expansion as a market leader in sustainable climate ceilings.


Interalu, based in Wilrijk (Antwerp), has over the past 50 years gained a leading position in the market for climate ceilings for non-residential buildings. Climate ceilings control the indoor climate with the highest level of comfort by means of heating and cooling radiation. Interalu is a frontrunner within the industry in terms of technology, sustainability and circularity.

Under the leadership of the Schrauwen family, the group has become the market leader in Belgium and Interalu has created compelling momentum in France, Luxembourg and the Netherlands.

With an ambition to accelerate growth and expand internationally, Interalu has engaged Waterland to support the next phase of growth. The execution of their joint growth plans will build on Interalu's existing unique value proposition, in which the trust relationship with customers as well as innovation and sustainability are central.

Anthony Schrauwen (CEO): "With Waterland we have found a very complementary and experienced partner who can help our family business to realize the next step. Together with the entire Interalu team, I am very much looking forward to working with Waterland and supporting existing and future customers across Europe in meeting their sustainability targets."
