Description

The GUTEX Thermowall-L, 120 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 = 3.05 m².K/W, it is particularly suitable for standard energy-efficiency renovations seeking a good balance between thickness and performance. 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.

GUTEX Thermowall-L 120 mm – Wood fibre EWI panel, R=3.05

Wood fibre for a balanced thermal renovation

The 120 mm thick GUTEX Thermowall-L panel is a wood fibre insulation board designed for eco-friendly external thermal insulation (ETI) systems. Manufactured in Germany from fir and spruce wood, it can be installed on masonry, concrete or solid timber walls, in both new-build and energy-efficient renovation projects. With a thermal conductivity of 0.039 W/(m·K) and a thermal resistance of R = 3.05 m²·K/W for a thickness of 120 mm, this panel meets the requirements of typical energy-efficient refurbishments seeking a good balance between thickness and performance. It retains the inherent qualities of wood fibre: good sound insulation, high thermal inertia and natural moisture regulation. Its permeability to water vapour promotes healthy and durable walls. The panel forms part of the complete Thermowall system, which combines approved fixings, laths and renders for reliable external insulation. Measuring 1200 x 400 mm and designed for edge-to-edge installation, it fits precisely, minimising thermal bridges at the joints. Its resistance to compression and tension makes it a reliable substrate for render finishes compatible with the system. This panel is designed for façade contractors, timber builders and private individuals undertaking a high-performance, sustainable and environmentally friendly external thermal insulation project.

Our EWI expert’s opinion

The 120 mm thickness strikes a good balance for renovation projects: decent performance, a reasonable thickness and a real improvement in summer comfort. Make sure you use a blade suitable for wood fibre to ensure clean cuts.

Why choose the GUTEX Thermowall-L 120 mm (wood fibre, R=3.05)?

GUTEX wood fibre offers better thermal inertia and greater comfort in summer than EPS, as well as being bio-based; however, graphite-reinforced EPS retains the advantage of superior thermal resistance for the same thickness.
