NBT Diffutherm

The NBT Masonry Diffutherm System is for externally insulating masonry brick/block buildings where they are to be externally finished with render. Diffutherm systems use woodfibre boards over the outside of the building in a continuous layer, thus providing a high performance unbridged thermal shell, with excellent acoustic properties, in a fully breathing construction. Mineral based breathable renders are provided for the outside of the wall, along with a range of fixings, tapes and rails. Mineral plasters and environmental paints can also be provided for the inside of the building.

System Application:

• Existing buildings: Diffutherm systems are highly vapour open and hygroscopic making them very suitable for the thermal upgrading of existing solid wall buildings as well as brick-infilled traditional timber frames, all of which need to breathe. They can also be used with cavity constructions.
• New Masonry walls: Diffutherm systems can be used with both new solid wall and cavity walls.
