Home Product News Sto helps create the right impression for Scottish school

One of the largest ever UK projects using StoTherm Classic M insulation and the Sto-Rotofix Plus fixing system has been completed in Scotland – the new Portobello High School, in Edinburgh.

StoTherm Classic M was chosen to provide high-level thermal performance for the new building. The EWI system features expanded polystyrene insulation boards and non-cementitious rendering components for impact resistance of 60 joules – up to 10 times greater than that provided by similar cementitious systems. This is a particular benefit for school projects of this type where the facade cladding may be subject to harsh treatment. The system was finished externally with a through-coloured StoSilco K silicone render for extra protection and to enhance the appearance.

Sto-Rotofix Plus was used to fix the insulation. It has a unique helical spiral fixing which allows the insulation boards to be mechanically fixed, quickly and reliably, and then easily adjusted so that a seamless facade can be created ready for rendering.
