Insulating Render and Plaster

Insulating Render/Plaster provides a highly breathable (vapour permeable) insulation solution for internal and external walls. It is particularly useful for upgrading the thermal performance of older homes where it is essential to preserve breathability in order to avoid damp and mould problems.

ProofTherm is formulated with mineral insulating aggregates and uses a hydraulic lime based binder, making it suitable for heritage building work as well as every day insulation upgrades.



Ultra-lightweight aggregates create an aerated screed that reduces heat flow through the floor, creating warmer rooms that cost less to heat.
