Frequently asked questions about the R'BULL Pro 20 Multicouches
What is the R'BULL Pro 20 Multicouches used for?
The R'BULL Pro 20 Multicouches is a 20 mm thin reflective insulation designed to supplement traditional insulation. It is installed as a sub-roof layer, on an interior wall or ceiling, on top of mineral wool, wood wool or another primary insulation. Its function is to reduce radiant heat transfer and slow down water vapour diffusion (Sd > 400 m).
What is its actual thermal resistance?
According to standard EN ISO 22097:2023, the R'BULL Pro 20 Multicouches has R = 1.32 m²K/W when installed with two unventilated 30 mm air gaps on each side. The thermal resistance of the insulation alone, excluding the associated air gaps, is R = 0.70 m²K/W. Its thermal conductivity is λ = 0.035 W/(m·K).
How is it installed with a traditional insulation?
The R'BULL Pro 20 Multicouches is installed as a supplement to a primary insulation (glass wool, rock wool, wood fibre) while maintaining two unventilated air gaps of at least 30 mm on each side of the assembly. It is this configuration that achieves R = 1.32 m²K/W. Installation follows the specifications of the European Technical Assessment ETA 22/0178.
Is it eligible for renovation grants?
In France, eligibility for support schemes (Energy Saving Certificates BAR-EN-109, MaPrimeRénov', BAR-TH-175 large-scale renovation) depends on the nature of the works, the overall insulation system and the thermal resistance threshold required by each scheme. The R'BULL Pro 20 Multicouches is designed to help reach these thresholds as a supplement to a primary insulation. See the Grants and subsidies page for details of thresholds by scheme.
Is it compatible with an RE 2020 or BBC renovation?
Yes. In France, the R'BULL Pro 20 Multicouches is used as a supplement to a primary insulation to meet the requirements of RE 2020 and large-scale renovations. Example figures for the supplement to add: 5.68 m²K/W in unconverted loft spaces to target R = 7; 4.68 m²K/W on roof slopes to target R = 6; 2.38 m²K/W on interior walls to target R = 3.7; 1.68 m²K/W on ground floors to target R = 3.
What is the difference from the R'BULL Pro 13?
The R'BULL Pro 13 is a 13 mm thin reflective insulation with 5 layers (reference BOLTHERM 235), with R = 1.60 m²K/W. The R'BULL Pro 20 Multicouches is a thicker product with 11 layers (reference BOLTHERM 820), designed to supplement insulation with two air gaps, R = 1.32 m²K/W. The Pro 13 aims for higher standalone performance, while the Pro 20 Multicouches optimises an existing insulation. See ADEME's position on thin insulation for the general regulatory context.
For compliant installation and eligibility for grants, use a qualified installer.
