Application

For use on existing or new, residential and non-residential high-rise buildings up to and over 18 m in height in the UK. The System can be designed for a 30 or 60-year service-life durability as required.

Description

The System is suitable for installation on external sheathed light gauge steel frame (LGSF) supporting walls and has a drained cavity behind the MW insulation. For use on existing or new, residential and non-residential high-rise buildings up to and over 18 m in height in height in the UK.


Cavity system consisting of EuroClass A1 components, mechanically fixed back to the inner sheathing board to create the designed cavity width with the insulation board fitted directly to the A1 fillets.


CS1 Fillet Strips are vertically orientated and mechanically fixed through sheathing board into SFS frame. This forms a minimum 15 mm drained cavity between the sheathing boards and the insulation layer. MW insulation in slab form is mechanically fixed through the plastic- coated glass-fibre reinforcing mesh embedded in the basecoat layer, into the sheathing boards. The System is completed with one of two available render finishes.
