Renovation of grass roof at Library of Delft with FOAMGLAS®
The library of Delft has a 5,500 m² sloping green roof, one of the first green roofs built at this scale. However, the multifunctional use of space for which this grass roof was designed turned out to be a cause of various leaks after a short time. The roofing had become damaged due to its use as a ski slope and camping site, but also due to the sliding of the grass roof and insufficient attention to proper detailing.
In 2006, the TU decided that complete renovation was the only good solution. The FOAMGLAS® insulation is completely adhered to the building, and both the insulation and the roof covering are completely stuck to each other. In this way, leakage and diffusion of moisture in the system is completely prevented.
