The greenest green roof

Installing a green roof is one of the smarter choices nowadays. You extend the life of your roof, increase the value of your home and more importantly, you actively contribute to the environment. With a sedum roof, you need to burn less gas in the winter and cool less in the summer.

The sedum plant is good for biodiversity, has a positive effect on health and well-being. The sedum roofing lowers the temperature and improves the efficiency of your solar panels.

But how do you make a green roof even greener?

Even more green

Add even more benefits to your green roof. Roof gravel off and greenSand on.

greenSand around your sedum roof repels algae growth and does not discolour. In addition, you actively nourish the soil and deacidify the rainwater.

And most importantly...

You clean up CO₂

CO₂ returns to the earth via rainwater and is converted into lime by a natural process. You clean up an average of 5 kg of CO₂ per square meter of green roof. In the Netherlands we have 21 million square meters of gray roofs. The clean-up potential is therefore enormous. Time for action!
