Thermal insulation

recycled textile fiberhemp fiberpanel

Summary
Biofib toiture is a bio-based insulation panel designed specifically for pitched roof (rafter) insulation. Made from hemp fibres grown in France and recycled textiles, it reduces thermal losses through the roof while improving occupants' hygrothermal comfort.

Composition and performance
Biofib toiture is composed of hemp fibres (cultivated in France) and recycled textiles. Measured performances include a thermal conductivity of 0.040 W/m·K (measured according to NF EN 12667) and a specific heat capacity of 1,800 J/kg·K, helping to limit summer overheating peaks and reduce winter heat loss. The product is marketed as healthy, free of volatile organic compounds (VOCs), and enhances hygrothermal comfort.

Installation and benefits for contractors

• Lightweight and easy to handle;
• Flexible, enabling precise fitting in irregular configurations (common in renovation) and maintaining insulation continuity;
• Easy to cut, non‑irritant and low dust emissions;
• Reduces physical strain on site.

Availability and positioning
Biofib toiture is available in four thicknesses: 80 mm, 100 mm, 145 mm and 200 mm. Presented as a product innovation, it was nominated for the 2026 Innovations Awards at the Paris Builders Show (category: building structure and envelope). Paired with Jetfib duo (loose-fill insulation for lofts), it completes the brand's bio-based roofing insulation range.
