Description

The StoTherm Mineral Lamella System comprises render finishes onto highly durable non-combustible rock mineral fibre insulation boards. Insulation boards are adhesively fixed, with supplementary mechanical fixings if necessary, to the masonry wall. 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 EN 13501-1 :2010 and can be installed without restriction in height or proximity to boundaries.

Quick Set (QS) versions of materials offer frost resistance and wash-off protection at temperatures from +1°C, reducing potential construction delays due to cold weather - consult manufacturer for recommendations.
