Insulating Floor Screed

Insulating Floor Screed

ProofTherm insulating floor screed is a lightweight, breathable and easy to use insulating screed that is suitable for use on almost all floor structures.

ProofTherm offers a low-cost, effective and simple way of insulating floors to provide greater thermal comfort and increased acoustic insulation. Suitable for use as a base layer for underfloor heating, it reduces heat loss through the floor and can be applied manually as a “dry” screed or pumped.

ProofTherm is an inert mineral product containing zero VOC’s. Advanced manufacturing and a unique formula have enabled us to create a high-performance, lightweight and breathable insulation solution for the 21st Century.
