Description

Steico Flex represents a fundamental shift in how we think about insulation. Where synthetic alternatives simply resist heat transfer, wood fibre actively contributes to a healthier indoor environment.

Why wood fibre insulation belongs in a healthy home:

• Hygroscopic performance: Wood fibre can absorb and release significant amounts of moisture — up to 15% of its weight — without losing insulating performance. This helps regulate humidity and prevents condensation within walls.
• No harmful emissions: Unlike some foam insulations, wood fibre contains no formaldehyde, no halogenated flame retardants, and no petrochemicals. It’s bonded with natural tree resins.
• Excellent acoustic performance: The fibrous structure absorbs sound effectively, creating quieter living spaces.
• Carbon storage: Wood fibre stores the carbon the trees absorbed during growth. Your insulation becomes a carbon sink rather than a carbon source.
• Pleasant to install: No itching, no respiratory irritation. Can be cut and handled without specialist protective equipment.

Technical performance:

Thermal conductivity of 0.038 W/mK makes Steico Flex competitive with mineral wool while offering superior moisture management. The flexible format friction-fits between timber studs and rafters, compressing slightly to eliminate gaps and thermal bridges.

Application:

Suitable for timber frame walls, pitched roofs between rafters, suspended timber floors, and internal wall insulation. Cut with a standard insulation knife or saw. Friction-fit installation — no adhesives required in most applications.
