Slatted roof, terrace canopy comprising the same, and a kit of parts and a method for assembling the same

Abstract

A slatted roof for a terrace canopy. The slatted roof is provided with a set of parallel slats (7, 7′), wherein two adjacent slats have a different bending resistance. The more rigid slat (7′) is intended for carrying, e.g. attaching thereto or integrating therein. of one or more desired components. These components then exert an additional load onto the more rigid slat such that both slats have substantially the same deflection. In this way, functional elements can be attached to a slat of the slatted roof without obtaining a slat with deviating deflection.
