MAPEI’S MAPETHERM SYSTEM ADDS TO THE SCENERY Two of Mapei’s complete external wall insulation and protective coating systems have been specified and installed on an impressive house renovation on the coast of Downderry, Cornwall. Contractor and client/project manager Jim Lockyer of James Lockyer Associates Ltd undertook the multi-disciplinary planning, design and specification of the project. Mapetherm EPS Plus insulation board, Mapetherm AR1 GG insulation adhesive and reinforcing render with Mapetherm Net was used over the existing masonry construction to provide thermal benefits. A new timber framed structure was added to the building and finished with a Mapetherm Thin Coat render only system; consisting of Mapetherm AR1 GG with reinforcing mesh (Mapetherm Net) and Mapetherm Plus System, which incorporates Silancolor Base Coat and Silancolor Tonachino Plus 1.2mm applied to a cement board. For a uniform finish, this is the ideal solution for a structure exposed to the extreme elements of a coastal location where mould and algae growth is prevalent. To provide a uniform finish, both systems were completed using Mapei’s protective and decorative coatings, Silancolor Base Coat and Silancolor Tonachino Plus 1.2mm. Mapei’s standard White, an off- white colour, was selected to complement the geographical setting along the coastal road. Mapei’s Silancolor Tonachino Plus is a trowel-applied, textured and coloured finish available in a range of grain sizes. It contains BioBlock® anti-mould and DropEffect® water-repellent properties, making it the ideal solution to coastal climates and those that favour damp. Mapei’s protective and decorative coatings are available in an infinite range of colours available with the ColorMap tinting system. www.mapei.com LISTED BUILDING CAN BREATHE AGAIN After more than 60 years as a school Grade II Listed Moreton House in Bideford, north Devon, has been returned to family ownership. Cement repairs and vinyl paints had caused a lot of damp to build up inside the walls. In many places moisture was trapped behind the paint. Internally, the walls are either lath and plaster or lime plastered stone. Earthborn’s Claypaint was specified to prevent future damp problems by ensuring the internal walls can breathe. Claypaint is virtually VOC free and does not give off any toxic emissions so it is safer for the health of building occupants as well as the environment. Its eco credentials include the stringent EU Ecolabel. Claypaint is available in Earthborn’s signature palette of 72 shades. www.earthbornpaints.co.uk Claypaint is a unique, clay based emulsion that maximises the natural properties of clay to create a high performance, highly breathable paint that covers exceptionally well and gives a distinctive, ultra matt finish.
