Description

The StoTherm Mineral M System comprises an impact resistant render finish to non-combustible rock mineral fibre insulation boards. The insulation is fixed by means of either Sto Rotofix Plus or Sto Rotofix mini helix spiral fixings. The system may be fixed to either bare concrete or masonry, previously rendered/ painted concrete or masonry, or onto a light steel framed or timber framed construction with suitable sheathing board. Through coloured render finishes are low maintenance, weather resistant and vapour permeable.

The system has an A2-s1, d0 reaction 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.
