Description

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.

GUTEX Thermowall-L 100 mm – Wood fibre EWI panel, R=2.55

Bio-based insulation for renovations where every centimetre counts

The 100 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 = 2.55 m²·K/W for a thickness of 100 mm, this panel meets the requirements of renovation projects where the available thickness on the façade is limited (roof overhangs, street alignment, window sills). 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 can be fitted with precision, 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

At 100 mm, wood fibre remains a viable option when space is limited on the façade: it maintains summer comfort and allows the wall to breathe. For higher performance at the same thickness, graphite-reinforced EPS will perform better, but without the thermal inertia of wood fibre.

Why choose the GUTEX Thermowall-L 100 mm (wood fibre, R=2.55)?

GUTEX wood fibre offers better thermal inertia and greater comfort in summer than EPS, as well as being bio-based; however, graphite-modified EPS retains the advantage of superior thermal resistance for the same thickness. GUTEX Thermowall-L 100 mm (wood fibre, R=2.55) TH32 graphite-grey EPS 100 mm
