KWS51 Aluminium Windows explained

The systems can be used for punched hole, composite and ribbon window applications. Also, both new build and refurbishment schemes. The window system is fully drained either onto a cill section or with our innovative face drain cap. This includes an internal baffl e, to stop wind noise, and to minimise, the build-up of water. Creating excellent weather resistance. The window suite can be dry glazed from the inside or outside using beads for ease of fabrication and quicker glass replacement. Trickle ventilation to building regulations, can be integrated into the KWS Window System.
