RETROFlexTherm is preferably used for sloped roofs. The Fresnel structure allows a horizontal arrangement of the louvers and thus an excellent visual transmission. The opening angle is determined by the free selectable distance between the louvers.
Due to the renovation of the reference library of the University of Mannheim, the temperatures below the glass roof were reduced by 10K.
