Particularly good for restoring older buildings or preserving heritage structures, our ecologically responsible solid wall insulation products are designed to not only protect stone and brick structures from the elements, but also regulate humidity and inhibit mould growth.

Our range of solid wall insulation includes thermal insulating plasters that not only provide excellent thermal benefits, but -when used with a finishing plaster- also a smooth finish that maintains the original features of heritage or period buildings.

Natural woodfibre and Calsitherm (made from lime and sand) insulation boards provide a straightforward installation that provides a breathable, solid layer on masonry walls. High performance and ecologically friendly, they also provide excellent moisture control and breathability.

Our solid wall insulation range includes products that are designed to be applied internally to solid walls, which allows you to preserve architectural facades whilst protecting both the internal and external structure, and products designed to be applied externally.

External wall insulation products include insulating plasters made from lime, cork, and clay, that can be applied to exterior walls. As well as providing excellent solid wall insulation to the building, it can also help walls in older buildings to dry out.

Because our products are made from ecologically friendly materials, using our solid wall insulation products provides peace of mind that your construction project is having minimal impact on the environment. In fact, some of our products, like the woodfibre Thermoroom insulation, are Carbon Negative.
