A cement-free external wall insulation system, with outstanding durability, crack resistance and weather protection.

The efficient single-leaf construction allows for excellent thermal performance without reducing the interior space. The mechanical fixing for this system allows the correction of irregularities on masonry and panel substrates by up to 60 mm.

This EWI system can be installed to a variety of substrates and finished with Sto weather resistant, vapour permeable, synthetic renders in a range of textures and up to 800 colours. Sto Brick Slips or StoDeco Profiles can also be applied for an alternative facade finish.

StoTherm Classic is BBA certified.
