Steico Flex: The High-Performance Breathable Layer
Replace mineral wool and synthetic foams with a natural material that actively manages moisture.
Our flexible wood fibre insulation batts (such as STEICOflex) are the ultimate solution for roof rafters, timber frame walls, and suspended floors. Unlike conventional insulation that can trap moisture and degrade structural timbers, wood fibres are naturally hygroscopic—they absorb and release humidity without losing their thermal efficiency.
-
Thermal Inertia: Keeps your home cool in the blistering Spanish summer and warm in the winter thanks to wood fibre’s outstanding heat accumulation capacity (phase shift).
-
Health First: No itching, no skin irritation, and completely free of toxic off-gassing. Safe for installers and residents alike.
-
Acoustic Comfort: The dense, porous wood fibre structure offers superior sound dampening compared to lightweight synthetic foams, keeping street noise outside where it belongs.
-
Heritage Safe: Fully vapour-permeable, making it the perfect choice for breathable historic retrofits and maintaining the integrity of traditional Spanish masonry.
Steico Rigid Boards: The Solid Insulation Solution
Robust thermal protection and weather resistance in one breathable panel.
For external roof insulation, sarking, or underfloor applications, Steico Rigid Boards (such as STEICOuniversal and STEICOtherm) offer a unique combination of compressive strength and thermal performance. Manufactured from sustainably sourced timber, these boards create a continuous, thermal bridge-free envelope around your home.
-
Moisture Regulation: The natural wood fibres provide a significant moisture buffer, helping to automatically regulate the indoor climate and prevent condensation.
-
Weather Protection: Engineered with precise tongue-and-groove profiles, these sarking boards are windproof and offer excellent resistance against rain, even before the final roof or cladding is applied.
-
Carbon Negative: These boards lock away more CO2 during timber growth than they emit during manufacturing, making your build actively climate-friendly.
-
Simple Application: Can be fitted directly over rafters or timber frames, providing a highly durable, flat surface that speeds construction.
Steico Protect: The Alternative to Synthetic Facades
Forget polystyrene. Finish your exterior with robust, acoustic, and breathable carrier boards.
Standard External Thermal Insulation Composite Systems (ETICS) often rely on EPS or XPS plastic foams that effectively seal your walls, reducing the structure’s breathability. Our STEICOprotect boards offer a robust, fully breathable alternative for exterior rendering and internal plastering.
-
Direct Plastering: Specifically designed as a render carrier board. You can apply breathable, natural lime renders or clay plasters directly onto the surface without the need for toxic primers or vapour barriers.
-
Acoustic Performance: While rigid plastic foams can echo and transmit sound, Steico’s high-density wood fibre absorbs sound vibrations, drastically reducing noise transfer into your living space.
-
Robustness: Denser and more structurally sound than standard insulation panels, providing a solid, impact-resistant finish to your facade.
-
True Breathability: Ensures that your external finish layer does not trap moisture inside the walls, maintaining the full “breathable ecosystem” of your property.
