Wood fibre

The 60 mm thick GUTEX Thermowall is a wood fibre render-bearing panel designed for external thermal insulation (ETI). With a thermal resistance of R = 1.50 m².K/W, it is suitable for façades where space is limited and for treating specific problem areas.

Denser than Thermowall-L, it offers high compressive strength – an advantage for a render substrate subject to stress – whilst retaining the qualities of wood fibre: thermal inertia, sound insulation and vapour permeability.

The GUTEX Thermowall-L, 100 mm thick, is a wood fibre render-bearing panel designed for external thermal insulation (ETI) of masonry, concrete or solid timber substrates. With a thermal resistance of R = 2.55 m².K/W, it is particularly suitable for renovation projects where the available thickness on the façade is limited (roof overhangs, street-facing facades, window sills).

Manufactured in Germany from fir and spruce, this board offers good dimensional stability, appreciable sound insulation and excellent thermal inertia, which helps to limit overheating in summer whilst retaining heat in winter.

The GUTEX Thermowall-L, 160 mm thick, is a wood fibre render-bearing panel designed for external thermal insulation (ETI) of masonry, concrete or solid timber substrates. With a thermal resistance of R = 4.10 m².K/W, it is particularly suitable for high-performance renovations and new builds requiring a thermal resistance greater than 4 m².K/W.

Manufactured in Germany from fir and spruce, this board offers good dimensional stability, appreciable sound insulation and excellent thermal inertia, which helps to limit overheating in summer whilst retaining heat in winter.

GUTEX Thermowall-L, 180 mm thick, is a wood fibre render-bearing board designed for external thermal insulation (ETI) of masonry, concrete or timber-frame structures. With a thermal resistance of R = 4.85 m².K/W, it forms part of the eco-friendly Thermowall EWI system, combining thermal performance, summer comfort and environmental sustainability.

Manufactured in Germany from fir and spruce wood, this panel offers good dimensional stability, appreciable sound insulation and excellent thermal inertia, which helps to limit overheating in summer whilst retaining heat in winter.

The GUTEX Thermowall-L, 240 mm thick, is a wood fibre render-bearing panel designed for external thermal insulation (ETI) of masonry, concrete or solid timber substrates. With a thermal resistance of R = 6.15 m².K/W, it is particularly suitable for projects requiring very high energy performance (low-energy buildings, ambitious renovations).

Manufactured in Germany from fir and spruce wood, this board offers good dimensional stability, appreciable sound insulation and excellent thermal inertia, which helps to limit overheating in summer whilst retaining heat in winter.
