ProofTherm provides a flexible, low-cost way of insulating walls and is particularly useful in the renovation and upgrading of older properties where its high vapour permeability allows the building to breathe, avoiding damp and mould problems internally. ProofTherm insulating render/plaster is 100% natural, breathable and easy to use. Suitable for use on most wall structures, it is the perfect way to refresh and renew the appearance of your property whilst protecting and insulating it for decades to come.

By insulating your external walls, you can significantly increase your home's thermal mass, which means your walls will retain heat far longer and will continue to radiate that heat back into the room long after the heating is switched off. The result is vastly improved thermal comfort, reduced damp and mold problems and healthy, comfortable living spaces. ProofTherm insulating render/plaster 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.

Questions & Answers


Can this be used on internal walls instead of normal plaster?


Yes, the product can either be used as part of a system or standalone in the place of normal plaster. 


When can I paint over it?


You should leave at least 24 hours before applying a finishing coat, ideally applying another mineral render layer before doing so. 


Can this be used on internal ceilings in a purpose built flat of concrete construction?


Unfortunately not - The product is designed to be used solely as a wall render/plaster, rather than on ceilings.


Can this product be used on interior stone walls?


Provided the stone wall is free of any loose material and any damaged sections repaired prior to installation, this should be absolutely fine, It might be worth reading up on the installation guide on behalf of the manufacturer for more information - https://www.insulationsuperstore.co.uk/user-guides-brochures/prooftherm-application-guide.html
