Steico
Steico SE is Europe’s leading manufacturer of natural building materials. Based in Germany with a strong presence across the UK, they provide integrated solutions for the building envelope, focusing on health, sustainability, and thermal performance.
Core Product Ranges
- Wood Fibre Insulation: Their flagship range includes flexible batts (Steico Flex) and rigid sarking boards (Steico Special). These are vapour-open (breathable), helping to regulate indoor humidity and protect timber structures from rot.
- Engineered Timber: They produce high-strength I-joists and LVL (Laminated Veneer Lumber). These components allow for long spans and high load-bearing capacities while reducing the "cold bridging" often found in solid timber or steel.
Key Performance Benefits
- Summer Heat Protection: Unlike mineral wool, wood fibre has high thermal mass, which prevents buildings from overheating during the summer months.
- Carbon Sequestration: Steico products act as a carbon sink, storing CO2 captured during the tree's growth, making them ideal for "Net Zero" and Passive House projects.
- Acoustic Insulation: The density of wood fibre provides superior sound-deadening properties compared to lightweight synthetic alternatives.
Sustainability
All Steico products are FSC® or PEFC certified, ensuring timber is sourced from responsibly managed forests. Their systems are designed to be fully recyclable at the end of the building's life cycle.
