Sustainable roofs for business

Flat roofs are a key element of sustainable buildings. These include roofs that contribute to saving energy, energy generation, water retention and green roofs. If the versatility of roofs is taken into account during the design phase, you can build a multifunctional roof. Our sustainable roofing and energy concepts are a part of innovative buildings across the Netherlands.

Sustainable materials

Sustainability is an important principle in all our projects. We work with sustainable and recyclable materials from the best suppliers. Our skilled installers also contribute to a long lifespan.


Insulating the roof of a building is a cost-effective way of saving energy. This is reflected in the Dutch Building Decree and other government regulations. For example, new construction projects must have a minimum Rc value of 6.0 m2.K/W. In addition, from 1 January 2023, existing office buildings larger than 100 m² must achieve energy label C or better. The most common roof insulation types are PIR, rock wool and EPS. We would be happy to advise you about the best roofing type for your project.

Solar panels

Did you know a white roof combined with solar panels delivers more energy? This type of roof covering is suitable for both new roofs and renovation projects. With existing roofs, it is important to assess the condition of the roof. If the roof covering is more than 10 years old, it may be advisable to replace it first and then install extra insulation. We would be happy to advise you about the best roofing type for use with solar panels.
