Impact sound insulation panel for floor structures
Gutex Thermofloor is the durable wood fibre sound insulation board for multi-purpose floor constructions with sound insulation requirements. With a load-bearing capacity of up to 5 kN/m² (excluding dry screed elements), it provides reliable insulation against airborne and impact noise and also offers thermal insulation - ideal under wet screed, mastic asphalt or chipboard or OSB installation panels.
Benefits
- Effective insulation against airborne and impact noise for a better quality of life
- High load-bearing capacity with up to 5 kN/m2 payload (excluding dry screed elements)
- Versatile use, also in combination with underfloor heating
Nominal value of thermal conductivity λD
0,040 W/mK
Design value of thermal conductivity λB
0,042 W/mK
Product details
Optimum preparation: Gutex Thermofloor as a substrate for wet screed, mastic asphalt or dry screed elements
Thermofloor ecological sound insulation reliably reduces noise pollution and provides high levels of insulation against airborne sound and impact noise - ideal for timber and concrete beam floors. It is highly resistant and ideally suited to robust floor structures with a load-bearing capacity of up to 5 kN/m² (excluding dry screed elements). Thanks to its dimensional accuracy, it is quick and easy to install.
Thermofloor ecological sound insulation provides reliable acoustic protection and effectively reduces noise pollution - ideal for wood beam and concrete ceilings. Its high dimensional accuracy makes installation quick and easy, while its high load-bearing capacity creates a basis for durable floor structures.
- Fast, easy installation thanks to high dimensional accuracy
- Durable and robust for strong floor structures
- Durable and recyclable, made in Germany
Ingredients
- Untreated fir and spruce wood
- For a panel thickness of 30 mm, 2.0% white glue for two-layer tape bonding

Storage and processing
- Store and use Thermofloor in a dry place.
Basement
- Create a dry, level and technically flawless substrate. If necessary, install a moisture barrier in accordance with DIN 18195 under the insulation surface.
- For ceilings with wooden beams: use anti-creep paper.
Cutting
- Cut using Gutex jigsaw blades or a hand-held circular saw; comply with the legal requirements for handling wood dust.

For higher insulation structures up to max. 100 mm.Gutex Thermosafe-wdto use.
- Place the off-cut from one row of laying at the start of the next row.
- Apply a fascia strip at the same height as the entire structure.
Note
- For damp screeds, place a damp-proofing film over the soundproofing panels.
