Installation of breathable insulating cork-based plaster at Eco Refurb project in Bristol

Lucy Pedler of The Green Register @greenregister organised a very interesting demonstration today of how to install Diathonite, a thermal insulating cork-based plaster. Sean Denton of Jordaya Contracting and his team applied a liquid cork and lime based plaster at Develeco's latest Eco Refurb project in Bristol: a conversation of a former Methodist Church hall into affordable starter homes. The existing external solid stone walls have a high moisture content and conventional impervious insulation was therefore not suitable. Diathonite has high vapour permeability and excellent acoustic properties. The base coat of Diathonite is sprayed on and then over-plastered with the same mix to achieve a homogenous, self-coloured coating.
