Erfurt KlimaTec is an energy conserving interior insulation system.

Erfurt Thermopanel / thermal fleece forms a barrier between cold walls and the air contained in a room. Heat fluxes are regulated and useful thermal energy used efficiently. As a result, rooms heat up noticeably faster and save heating energy. The manufacturer claims that rooms can be heated up to 75% faster and with less energy.

Additionally, this material is breathable and therefore suited for the prevention of mold. Furthermore, it is sound absorbing (average absorption coefficient αw=0.2) and can be used for crack bridging.
