STEICO is the world market leader in wood fiber insulation.
The STEICO Group develops, produces and sells environmentally friendly building materials made from renewable raw materials.

STEICO positions itself as a supplier of ecological building systems and offers a unique product diversity and degree of integration. In addition to wood-fiber insulation, building components such as I-beam systems and lamibois are also the company's core business. Insulation products include rigid and semi-rigid wood-fiber boards, facade insulation and loose-fill insulation. Waterproofing membranes for building envelopes complete our offering.

All STEICO's French products are manufactured at the Casteljaloux site in Lot-et-Garonne.
The Casteljaloux plant currently has two production lines for STEICOflex semi-rigid insulation, supplying the entire French market as well as Spain with these highly sought-after panels. An LDF (Low Density Fibre) board line was also inaugurated at the end of 2022.

STEICO has increased its production capacity to meet growing demand for wood fiber insulation in France. In addition to creating jobs, the new LDF line will reduce delivery times and costs for the French market. Indeed, demand for insulation manufactured using dry processes is high, and will certainly continue to rise with the RE 2020, which favors bio-sourced materials that contribute to decarbonization.
