STEICO develops, produces and markets ecological construction products made of renewable raw materials.

STEICO is positioned as a system provider for ecological residential construction and is the only manufacturer in the industry to offer an integrated wooden construction system in which insulation material and construction components supplement each other.

These include flexible and stable wood fiber insulation panels, composite thermal insulation systems, insulation panels with a reinforcing effect, as well as cavity wall insulation made of wood fibers and cellulose. The construction elements comprise I-joists and laminated veneer lumber. In addition, the STEICO group also produces hardboards (Natural Fibre Boards) and operates in the wood trade.

The Munich-based company’s products are used in new construction and when renovating roofs, walls, ceilings, floors and facades. STEICO’s products allow the construction of future-proof, healthy buildings with a particularly high quality of living and a healthy atmosphere. STEICO’s products offer reliable protection against cold, heat and also noise, and they permanently improve the building’s energy efficiency. 


The STEICO construction system has received the recognised Passive House certification.

STEICO was the first manufacturer to have their entire range of wood fibre insulation materials certified by the FSC (Forest Stewardship Council). Thus the products are environmentally certified from the forest to the building site.
