Imagine a home where you feel comfortable all year round. That's exactly what Gutex wood fibre insulation materials offer. Not only do they protect against heat, cold and noise, they also promote a healthy indoor climate where you and your family can breathe easy. And they are sustainable down to the last fibre: made from PEFC-certified wood (PEFC/04-34-0006), they are durable and recyclable. Whether for your energy-efficient walls, your rain- and hail-proof roof, or your construction-safe interior design, our open-cell insulation materials diffusion and regulate humidity not only ensure the physical safety of the building, but also reduce the risk of mould inside or algae on the facades. With Gutex, you are not only insulating for today, but for generations to come: energy-efficient, environmentally friendly, comfortable and well thought-out.

If you want to build sustainably and protect the climate - even beyond the reduced energy consumption of insulation - then wood-fibre insulation is the only option, because wood is the most durable of all building materials:Using environmentally-friendly wood fibresyou also use the carbon stored there as a component of the CO2- but wood fibre thermal insulation is not only recyclable - unlike conventional insulation materials, it's also compostable, which helps to combat the growing waste mountain.
To maximise this sustainability value, we process it to environmentally-friendly standards. If you'd like to find out more about the sustainable quality of our products, take a look at our certificates and seals.
Naturally, we also provide detailed information on the benefits of our environmentally-friendly insulation materials: from energy efficiency and protection against heat, cold, noise and fire to preserving the value of your building.
Under-roof panelsUltrathermandMultiplex-topfor roof pitches of 15° and above, meet the requirements of temporary roofing up to an RDN undershoot of 8° and no further requirements without additional gluing or film covering. The panels are assigned to technical class UDP-A in accordance with ZVDH.
Z-33.47-660 and Z-33.43-942 approvals for the thermal insulation systemThermowallyou can choose a coating from more than 15 manufacturers and find all the details - brands, components, use - in the approvals.
You can use wood fibre insulation boardMultithermas an external cladding on frameworks, solid wood elements or masonry. Immediately fix the insulation panel with the ventilation batten. For the dimensioning of the fixings according to the object, please use the dimensioning service of your fixing manufacturer.
In the case of a closed façade, you don't need an additional façade strip onMultithermin the case of open-joint formwork, we recommend the use of a UV-resistant, waterproof façade sheet.
In timber-frame construction, fit the Thermowall/-gf/NF/Durioon flat wooden substrates such as solid wood walls, fit the plaster support panel, distributing it evenly according to our dowel diagrams. To fix, use the wood screwThermowallSTR H or stainless steel wide-back staples.
On mineral substrates, insulating panelsThermowallmust always be glued and doweled, for example using Gutex gluing and smoothing compound and Gutex STR U 2G screw dowels.
For more information, see the brochure "Gutex Thermowall WDVS - how to use".
You can find examples of how to insulate the upper storey ceiling in the construction proposals (link). We also recommend Stampio, our wood-fibre insulation system for the upper storey ceiling.
You can cut thinner board thicknesses or small quantities of the flexible wood fibre insulation blanketThermoflexfor larger quantities, we recommend using an electric insulation saw with a corrugated blade, such as the cordless insulation saw from Festool or the Alligator from Bosch.
When insulating above the rafters with our sub-roofing panels, the following distances between the rafters must be observed:
Product | Panel thickness [mm] | Max. length Rafter centre distance [cm] |
|---|---|---|
GutexTop multiplex | 22 | 85 |
35 | 100 | |
GutexUltratherm | 50 / 60 | 110 |
80 / 100/ 120/ 140/ 160 | 125 | |
GutexMultitherm | ≥ 60 | 90 |
You'll find the ingredients on the pages for each product under "Additional information" and on the technical data sheets under "Downloads".
Our insulation materials are synonymous with controlled quality and durability. Certificates such as natureplus or FDES environmental declaration sheets guarantee the highest standards - for peace of mind in every construction project. It goes without saying that our products comply with building regulations and with the relevant NF standards or bear the CE mark.
