External wall insulation

Lime Green’s Warmshell system is an effective and simple way to make walls warm and dry and helps keep buildings and residents healthy. The system achieves the warmest walls possible and does so sustainably and in a environmentally friendly way, with breathable lime products at its heart.

The Warmshell thermal board is normally fixed on the outside of a building, once fixed it is rendered with lime renders giving a breathable, weather-resistant wall. It is ideal for upgrading walls on many old, cold houses or for building a super-insulated wall from scratch.
