UNOCCUPIED ATTICS
BIO-BASED INSULATION - RECYCLED TEXTILE
R-VRAC is a thermal and acoustic insulation, made from cotton wool derived from textile recycling. A healthy and ecological alternative to conventional wools.
With a lambda of 0.048W/(m.K), ACERMI certified, good thermal phase shift, excellent sound insulation, and good water vapor management.
This product is installed by manual spreading or pneumatic blowing:
- on floors of unoccupied or hard-to-access attics
- on plasterboard ceilings on frameworks compliant with standard NF DTU 25.41
Its flake format allows for homogeneous distribution and limits thermal bridges. Light, soft, low-dust, and non-irritating, R-VRAC offers clean and comfortable installation.
R-VRAC

THERMAL PERFORMANCE AND COMFORT
Effective in winter and summer
With a thermal conductivity of 0.048 W/(m.K) and a thermal phase shift of 6 to 8 hours, R-VRAC provides a barrier against winter cold and blocks summer heat.
Natural humidity regulation
Thanks to the hygroscopic properties of cotton wool, your home "breathes" better, preventing condensation problems.
Excellent sound insulation
The fibrous structure of recycled cotton absorbs airborne and impact noise, providing superior acoustic comfort.
DURABILITY AND HEALTH
50-year guaranteed lifespan
Our solution is designed not to settle over time, maintaining its thermal resistance for 5 decades.
Healthy environment and natural repellent
Rated A+, R-VRAC releases no VOCs. Its composition is naturally unattractive to rodents.
EASE OF INSTALLATION
Flexible installation (spreading or blowing)
The product can be installed either manually by spreading or by pneumatic blowing to reach hard-to-access areas.
Ultra-light and easy to handle
At only 4.8 kg/m² for an R=7 resistance, it does not overload ceilings and is easy to transport on site.
ECONOMY AND LOCAL SOURCING
Eligible for renovation grants
R-VRAC meets the technical criteria for French renovation grants (MaPrimeRénov', CEE).
Short supply chain in Hauts-de-France
From sourcing to manufacturing, our insulation supports the local economy with 100% regional production.
