Green roof system Topgreen is suitable for both flat and sloping roofs with a slope of up to 45°. The substrate and sedum are located in a recycled plastic cassette. A difference with Ecopan is that Topgreen elements are laid on top of each other. Ecopan elements are laid inside each other, similar to roof tiles.

Topgreen GDS 15 sedum cassette

With the innovative GDS15 system from Topgreen, your roof will be green in no time without having to make too many adjustments. GDS 15 is suitable for use on flat and slightly sloping roofs up to 15°. We can also offer this system as a vegetated sedum cassette.

Topgreen sedum cassettes with sedum from our own nursery

In our nursery in Holten, we grow our sedum in the sedum cassettes from Topgreen. Our nursery is known for its high quality and environmentally friendly cultivation methods. By growing the sedum directly with us, we can guarantee optimal growing conditions and ensure healthy, robust plants. These cassettes are ideal for quick and easy installation of green roofs, and offer a sustainable solution for both private and commercial projects. In addition, local cultivation reduces transport distances and therefore CO2 emissions.

Pitched roofs

For pitched roofs, we also offer several systems, both vapour-open and vapour-tight. You can find more information about this on this page.
