The next-generation reflective thermal insulation
R'BULL Pro 5: the 5 mm thin reflective insulation at a glance
Don’t just replace your insulation. Enhance it.
R'BULL Pro 5 is designed to complement your traditional insulation materials (glass wool, rock wool, wood fibre). When used with fibrous insulation, it helps achieve the thermal resistance levels required by RE 2020 and major renovation projects (BAR-TH-175). It is based on R'BULL reflective technology.
- Unused loft space: as a supplement, add 5.89 m².K/W to meet the 7 m².K/W requirement.
- Roof slopes: 4.89 m².K/W to be added to meet 6 m².K/W.
- Interior walls: 2.59 m².K/W to be added to meet 3.7 m².K/W.
- Ground floors: 1.89 m².K/W to be added to meet the required 3 m².K/W.

R'BULL Pro 5 in action
Much more than just insulation, an active thermal barrier that enhances your structure. View the technical cross-section of absolute performance.
- Permanent thermal bridge break
- Static thermal air gap created
- Maximum summer protection (95% of infrared rays reflected)
The Anatomy of Absolute Comfort
5 millimetres. No more. No less. The R'BULL Pro 5 takes the concept of reflective insulation to the extreme: maximum performance in the minimum of space, without compromise.
The Roof
Tiles and battens do their job in silence: deflecting, filtering, allowing the roof to breathe. This first layer lays the groundwork so that the R'BULL Pro 5 can reach its full potential from the very next layer.
The R'BULL Pro 5 Shield
Barely five millimetres thick, yet it reflects 95% of solar radiation. Two thin sheets of pure aluminium encase a high-performance core: waterproof, lightweight, unbeatable. When space is at a premium, the R'BULL Pro 5 is the answer.
The Active Air Gap
Behind every great insulation system lies a simple truth: still air is the best insulator there is. Sealed by the R'BULL, this microscopic yet crucial space transforms your roof into a true thermal barrier.
The Finish
Plasterboard on battens: the finishing touch to a clean, professional installation. And because every project has its own requirements, the R'BULL Pro 5 works perfectly with fibre insulation for a bespoke performance. See the full R'BULL range.

R'BULL Pro 5: frequently asked questions
Radiation, fire safety, compatibility with existing structures: factual answers about the 5 mm thin reflective insulation.
R'BULL Pro 5 acts on radiation, not just on conduction. Its two pure aluminium faces reflect up to 95% of infrared radiation. When combined with an unventilated air gap, it achieves an R-value of 1.11 m²K/W in accordance with standard EN ISO 22097:2023. It is designed to complement fibrous insulation, never as a replacement. Schemes such as the CEE grant and MaPrimeRénov' may be available to support this type of work.
The R'BULL Pro 5 is classified as B-s1,d0 (reaction to fire, EN 13501-1). This classification means no flame spread, very low smoke emission and no flaming droplets. It makes the product suitable for public access buildings. For the regulatory framework, see the ADEME’s position.
No. R'BULL Pro 5 complements the existing insulation. It manages radiant heat for summer comfort, whilst the wool manages conductive heat in winter. Together, they form a high-performance hybrid insulation system.
Installation is quick and dust-free. It adds virtually no height to the ceiling. At 5 mm thick, the product provides a thermal barrier and a vapour barrier (Sd > 260 m, EN 12086).
