Façade Windesheim college, Zwolle

The façade comprises of large lightweight composite panels which integrate multiple functions: structure, insulation and aesthetics. Because of the lightweight structure, panels of quite large sizes could be produced, therefore ensuring time and cost savings during the assembly process. The production of the panels also happened in parallel to the process of the building being built.

Integration of functions

By combining functions such as strength and insulation in one product, a composite solution is often more cost effective than the sum of traditional solutions.


The specific weight of composites varies between 1.5 and 2.0 compared to 2.7 to 7.8 for aluminium and steel.


Typical GRP lambda values are 1, compared to 50 for steel and 237 for aluminium, which results in excellent insulation properties.
