Natural Building Technologies’ (NBT) ThermoPlan Plus system has been used for Alexander House, a luxury eight-bedroom holiday home in Perthshire, Scotland.

NBT’s Thermoplan thin joint fired clay blocks were used for the walls and overclad with a layer of NBT’s Diffutherm woodfibre insulation.

The walls are finished with NBT’s natural lime render. The company says that the system gives the external walls a U-value of 0.15W/m2K and is also highly breathable and non-toxic,
which helps maintain a dry, healthy internal environment. The ThermoPlan system is also LABC registered.
