ProofTherm Insulating Screed is an ultra lightweight screed which can be used at thicknesses between 20mm and 300mm to provide thermal and acoustic insulation for floors.  It is supplied as a dry, bagged mix which just requires the addition of water and can be mixed and applied by hand or by machine pump.  ProofTherm screed is easy to use and doesn’t require specialist skills or training.

Typical use is for levelling uneven substrates with an insulating layer prior to the final floor finish. It is widely used in conversions and renovations of older properties and in all scenarios where weight is a potential issue.

ProofTherm insulating screed is a useful alternative where traditional floor insulation methods or products are not practical. It forms a continuous thermal barrier with no thermal bridging, reducing heat loss through the floor and helping to create a more comfortable living space.

One 25kg bag covers approximately 3.3m2 per 10mm application depth.


With a thermal conductivity of 0.088 w/m2K ProofTherm Insulating Screed provides a valuable insulating solution in all sorts of scenarios
