Blown-in wood fibre insulation for compartments and horizontal surfaces
Gutex Thermofibre has a consistently high quality like no other blown-in wood fibre insulation, making it not only the safest insulation from a building physics point of view, but also the most economical thanks to its low consumption. It can be processed very efficiently using machines, and fills compartments seamlessly and evenly - even with irregular shapes. The result is high-quality insulation and connections without thermal bridges. Thanks to the special structure of their fibres, even at relatively low densities, wood fibres develop an elastic tensile strength that enables them to support each other stably, ensuring high long-term settlement resistance.
- Blown without settling from 29 kg/m³ thanks to the structure and quality of the fibres
- Uniform, seamless insulation, even in complex lattice geometries
- High profitability thanks to relatively low use of materials

Product details
Consistently high quality, low use of materials
Thermofibre is ideal for providing uniform and economical insulation for compartments measuring approximately 15 cm wide and 8 cm deep. The minimum blowing density is 25 kg/m³ for open blowing, 29 kg/m³ for closed blowing and 38 kg/m³ for prefabrication with a blowing panel (transport safety). It has excellent flow properties and low dust content, which facilitates its application. Thanks to its low thermal conductivity and high heat storage capacity, this eco-friendly wood fibre insulation provides excellent thermal protection, while its high density and flow resistance ensure effective sound insulation. Its moisture diffusion and regulation properties also promote a healthy indoor climate. Sustainable Thermofibre poses no risk to the building, as it is made from bark-free coniferous wood and contains no fungicides or borates.
- Excellent protection against heat and cold thanks to high heat storage capacity and low thermal conductivity
- Construction-safe thanks to the absence of fungicides and borates (natureplus certified)
- Recyclable, made in Germany
Ingredients
- Untreated fir and spruce wood
