System performance

Structural performance - permanent and imposed loads


Surfaces must be sound, free from loose material and clean.

Where an adhesive system is used, the surfaces must be sound, free from loose material and clean. Where additional mechanical fixings are to be used, the substrate must be capable of sustaining the design loads.

Approved proprietary biocidal wash.

Existing substrates that show visible signs of algae and mold will require treating with an approved proprietary biocidal wash prior to any render works.

Support rails and brackets





Not required.

 For brick and blockwork substrates. 

A1 Fibre Cement Board.

For steel and timber framed substrates.


All fixings are based upon Etag and BBA certification and the manufacturers products are designed and tested to fully comply with current required certifications and testing.





MW Dual Density 036.

Dual density mineral wool slabs available in sizes up to 1200 x 600 mm and in a range of thicknesses from 40–240 mm, with nominal densities of 160/100 kg/m³ (outer/inner layer), a minimum compressive strength of 10 kPa and a tensile resistance perpendicular to the faces of 10 kPa. Slabs are manufactured to comply with BS EN 13162:2012. 


Raso Top Bio.

A biocompatible skim coating/adhesive, certified as GP mortar in accordance with the UNI EN 998-1 standard, specifically designed for applications requiring extremely high breathability. 

Additional mechanical fixings

Designed and tested to meet the current wind load and suction requirements, the system is adhesively fixed with supplementary fixings in accordance with BS EN 1991-1-4:2005. Special consideration should be given to locations with high wind-load pressure coefficients, as additional fixings may be necessary. It is recommended that a load factor of 1.5 is used to determine the ultimate wind load, in accordance with BS EN 1990:2002.
