Description

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.

GUTEX Thermowall-L 180 mm – Wood fibre external wall insulation board, R=4.85

Bio-based insulation that combines thermal performance with summer comfort

The 180 mm thick GUTEX Thermowall-L panel is a wood fibre insulation board suitable for rendering, designed for environmentally friendly external thermal insulation (ETI) systems. Manufactured in Germany from fir and spruce wood, it can be installed on masonry, concrete or timber-framed walls, in both new-build and energy-efficient renovation projects. With a thermal conductivity of 0.037 W/(m·K) and a thermal resistance of R = 4.85 m²·K/W for a thickness of 180 mm, this panel offers high-performance insulation whilst maintaining good thermal mass. This heat storage capacity improves comfort in summer by limiting overheating, a benefit sought after by tradespeople and façade specialists involved in demanding energy-efficient renovation projects. Its bio-based composition, combined with its permeability to water vapour, promotes humidity regulation within the wall and contributes to healthier façades over the long term. The panel forms part of the complete Thermowall system, which includes fixings, a mesh framework and approved renderings for reliable and durable external insulation. Measuring 1200 x 400 mm and designed for edge-to-edge installation, it fits precisely, minimising thermal bridges at the joints. Its mechanical resistance to compression and tension makes it a reliable substrate for mineral or organic façade finishes compatible with the system. This panel is designed for construction companies, façade specialists and timber builders seeking a high-performance, durable and environmentally friendly external thermal insulation solution, for both new-build and energy-efficient renovation projects.

Our ITE expert’s opinion

GUTEX wood fibre insulation offers a real boost to summer comfort thanks to its thermal inertia – a benefit that customers who are sensitive to summer heat will appreciate. In practice, it is slightly more difficult to cut than EPS: make sure you use a suitable blade.

Why choose GUTEX Thermowall-L 180 mm (wood fibre, R=4.85)?

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