Insulated render system based on adhesive and mechanically fixed non-combustible dual density rock mineral fibre insulation.
The StoTherm Mineral K System comprises an impact resistant render finish to non-combustible rock mineral fibre insulation boards. Insulation boards are adhesive and mechanically fixed to a masonry or suitably sheathed light steel frame substrate. Through coloured render finishes are low maintenance, weather resistant and vapour permeable.
The system has an A2-s1, d0reaction to fire classification in accordance with BS EN 13501-1 :2010 and can be installed without restriction in height or proximity to boundaries.
For insulation and render finishes to below DPC zones consult manufacturer.
Quick Set (QS) versions of materials offer frost resistance and wash-off protection at temperatures from +1°C and 95% relative humidity, reducing potential construction delays due to cold weather - consult manufacturer for recommendations.
