GUTEX Thermowall-L 200 mm – Wood fibre external wall insulation board, R=5.40

Enhanced insulation for the most demanding energy projects

The 200 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 timber-framed walls for new-build projects or energy-efficient refurbishments. With a thermal conductivity of 0.037 W/(m·K) and a thermal resistance of R = 5.40 m²·K/W for a thickness of 200 mm, this panel meets high energy performance requirements whilst retaining 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, an important criterion for tradespeople and façade specialists involved in comprehensive energy-efficient renovations. The panel forms part of the complete Thermowall system, featuring approved fixings, lathwork and renders, for reliable external insulation from start to finish. Measuring 1200 x 400 mm and designed for edge-to-edge installation, it is fitted with high dimensional accuracy, minimising thermal bridges at the joints between panels. Its resistance to compression and tension makes it a reliable substrate for the render finishes specified within the system. This panel is designed for construction companies, façade specialists and timber builders seeking high-performance, bio-based external thermal insulation, suitable for projects aiming for a high level of energy efficiency, in both new builds and refurbishments.

Our ITE expert’s opinion

At this thickness of 200 mm, the balance between thermal performance and summer comfort offered by wood fibre is particularly appealing for energy-efficient refurbishments with high standards. Bear in mind the weight of the panel, which is heavier than an equivalent EPS panel: make sure you plan for handling it.
