ProofTherm Lightweight Insulating Screed
ProofTherm Insulating Screed combines Perlite and Pumice aggregates to create an ultra-lightweight screed underlay with excellent insulating properties. Perlite and Pumice are naturally occurring volcanic rocks that form with a highly aerated honeycomb structure. These tiny air bubbles trapped in ProofTherm’s aggregates create a barrier to thermal conductivity and also reduce acoustic transmission. It can be used as an underlay to insulate floors at depths between 20mm and 120mm, either directly onto an existing slab/substrate or in combination with a damp proof membrane. ProofTherm insulating screed is not designed to provide a permanent wearable surface and should be finished off with a durable self-levelling screed/compound or final decorative surface.

ProofTherm offers a low-cost, effective and simple way of insulating floors to provide greater thermal comfort and increased acoustic insulation.
