About Bauwer Group

Lightweight, breathable thermal render and plaster effectively controls moisture passing through a stone or brick wall. Being breathable means that the render allows balanced moisture movement through the construction fabric allowing the substrate to dry naturally

Bauwer render and plaster contain lightweight Perlite which, along with low density, improves the insulation properties of the wall. The low weight reduces the stress put on structures. This is especially important when working on traditional and historical projects.

Bauwer thermal rendering products are class A rated fire resistant and non-combustible.
