External sun shading in exposed locations poses additional challenges. Warema’s range of Wind-Stable External Venetian Blinds extends their use to mid-rise buildings up to approximately 12 levels or applications where the acceptable wind threshold is up to 90 km/h. The wind stable profile offers the rigidity of a rolled edge slat with a unique special interlocking shape that forms a firmly braced plane against wind pressure. Furthermore two forms of guidance work in unison to securely anchor the slat ends, and a partitioning guide rail profile ensures that vacuum effects on the building side are minimized.
