Warmshell Internal is used on historic masonry and timber houses, where its ability to buffer and control moisture makes it the ideal insulation system for a comfortable, healthy home.

By installing Warmshell internal insulation to the inside of the property, it is important that as much of the internal wall is covered.

  • Existing lime plaster or a new levelling coat of Lime Green Duro

  • Woodfibre boards fixed with either WT hammer in fixings or WTS screw in depending on nature of the wall.

  • Plaster with Lime Green Solo 10mm thick, including glass fibre mesh.

  • Paint with breathable paints, such as Earthborn or Beeck.
