Product innovation:

Large textile umbrellas for convertible roofs for climatic comfort

For more than 30 years, SL-Rasch has developed and optimized large umbrella structures that are successfully used worldwide as convertible roofs. These light translucent membrane vaults protect against sun and rain and transform outdoor spaces into architectural structures of the highest quality. If deployed during the day, the high-quality Teflon fabrics reflect more than 70 % of the irradiated solar energy. Closed at night, the area can cool down under the clear cold night sky which is appreciated on the next day. These convertible umbrella structures offer climatic comfort by controlling irradiation.
