BBA Agrément Certificate
Certificate type
A highly durable external wall insulation with mineral fibre boards and mineralic render, providing excellent fire protection and thermal performance.
Application
Suitable for fixing 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. For new build or refurbishment projects. Can be installed without restriction in height or proximity to boundaries.
To fix insulation to masonry, concrete and panel backgrounds, a range of Sto-Rotofix fixings are available. Spacing and number of fixings to suit substrate and wind load conditions.
Finishes
Render - Stolit, StoSilco, StoLotusan
Architectural Elements - StoCleyer B brick slips, StoEco shapes, StoDeco panels or profiles
Range of intelligent facade paints
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.
Impact loading (ETAG 004):
- Single layer standard mesh - Category II.
- Single layer Armour mesh + single layer standard mesh - Category I (with StoArmat Classic Plus reinforcing coat).
Consult manufacturer for details and recommendations.
