During the Renovation & Transformation 2025 trade fair, together with Schakel & Schrale, we are showing what the bio-based and smart renovation of monumental roofs can look like. After a successful first day, we are still on hand today and tomorrow to give visitors an exclusive look at our solution for Bimsbeton: our own Duplicor® Bimsbeton replica.
Monumental appearance, modern performance
Many monumental buildings in the Netherlands feature Bimsbeton - a material popular in the last century for its easy workmanship. It is commonly found in buildings from the 1920s and 1930s; think train stations or factories. Meanwhile, the then-innovative concrete has become obsolete due to its weight, poor insulation and susceptibility to damage. Now you can choose to keep repairing the original Bims concrete, but that's carrying water to the sea. Our Duplicor® Bims concrete replica offers a durable and aesthetically identical alternative, approved by the Rijksdienst voor het Cultureel Erfgoed.
What makes this solution special?
- Lightweight: thanks to a core of recycled PET foam.
- Thermally insulating: improves the property's energy label.
- Constructively efficient: no replacement or reinforcement of rafters required.
- Historically responsible: while maintaining the original appearance.
A proven collaboration
Together with Schakel & Schrale, we have already applied this innovative solution in the renovation of the Tramremise on Lekstraat in Amsterdam; a building dating from 1927 of which a total of approximately 10,000 m² of roof is currently being replaced with Duplicor® replica “Bims concrete elements”.

From past to future
Our goal is clear: to harness the power of composite materials to future-proof existing buildings - without compromising their character. Thanks to the Duplicor® Bims concrete replica, listed buildings can meet today's requirements with the aesthetics of old: from insulation and weight, to durability and appearance.
Curious? We would be happy to tell you more.
Visit us at the trade fair and discover how we, together with Schakel & Schrale, are making a difference in monumental Netherlands.
Will we see you there?
