The membrane roof by seele covers an area of about 892sqm. It consists of four-layer ETFE film cushions, the uppermost layer of which is printed on the inside with silver dots that cover 50% of the area. This four-layer ETFE film design means several insulating layers that ensure an optimum U-value.
Combined with the printing, the result is an efficient, energyconscious solution. The reflective property of the membrane roof also reduces the heat build-up in the atrium. The printed dots ensure an agreeable, diffuse scattering of the incoming light and thus a pleasant interior atmosphere during any type of weather.
