Product details
Your home, naturally insulated: Gutex Thermoflex
Thermoflex ecological wood-fibre insulation is generally very easy to install: it releases less dust than comparable insulation batts, which benefits people and cleanliness on the building site. What's more, it can be cut quickly and accurately, saving time and avoiding falls. The homogeneous structure of this flexible wood-fibre insulation batts gives it a convincing appearance; its low raw density gives it a high insulating capacity. This is complemented by its exceptional thermal resistance, which, combined with its very high heat-storage capacity, ensures the best insulation results and a comfortable indoor climate throughout the house. With a wide choice of thicknesses and formats, Gutex Thermoflex is ideal for implementing the most diverse timber construction concepts.
One panel, many possibilities: roof, ceiling, inside wall, outside wall
Thermoflex insulation blanket is the environmentally-friendly wood fibre insulation for a wide range of applications: from rafter insulation in roofs to compartment insulation in the spaces between wooden studs in internal and external walls. It is also suitable for insulating ceilings and for use in partition walls and dry construction.
Ingredients
- Untreated fir and spruce wood
- 6% Ammonium salts
- approx. 5% textile binding fibres

Storage
- Store and use insulation boards in a dry place, protected from moisture.
Cutting
- With an electric handsaw, a band saw, suitable saws for insulating materials, orGutex knife for insulating materialsthe legal provisions governing the handling of wood dust must be complied with.
Drilling
- With metal or stone drills at full speed.
- Hole saw available for holes in flush-mounted boxes or pipe penetrations.
Temperature resistance
- Can be exposed to temperatures of up to 100°C, even for prolonged periods; cannot be exposed to open flames.
- Ideally, encapsulate local heat sources such as recessed lamps, etc. with appropriate boxes.
Gutex Thermoflex between wooden studs and beams for insulating ceilings, external walls, partitions, etc.
Cutting
- With excess length and width according to the clamping table below. The excess clamping thickness is ≥ 1% of the internal width of the span.

Note:Spans may vary depending on the construction, the nature of the rafters or ceiling beams and the pitch of the roof..
Treatment
- Thermal bridges are avoided by compressing the panel.
- Taking into account the extra height when cutting, it is also possible to clamp two pieces next to each other to minimise off-cuts.
- Secure roof and ceiling insulation blankets after three days at the latest to prevent them from falling.

Treatment
- First insulate the end fields with the CW profiles facing each other.
- Adjust the wood-fibre insulation, move the profiles into their final position and fix them, then insulate the remaining panels.

Note
Filling in around 80% of timber-framed internal walls improves sound insulation, because the air space remaining in the compartments reduces sound transmission and thus contributes to effective sound insulation.
