With 40 years of proven on-site performance, Knauf Insulation’s Earthwool DriTherm Cavity Slabs are the built-in insulation of choice for fully filling cavity walls.
This glass mineral wool solution has been a favourite of bricklayers for many years. The slabs do not require any additional fixings to hold them in place, and can be easily cut with a trowel.
What’s more, the BBA approved slabs can also be used in all exposure zones. Only in severe exposure zones do the NHBC require that fair-faced masonry is rendered or cladded. As a high quality, non-combustible material, Earthwool DriTherm also achieves the Euroclass A1 reaction to fire rating.
