"Ecological construction products and insulation from a single source."

The STEICO Building System – Nature 2.0

Load-bearing capacity, precision, energy efficiency - modern timber constructions place special demands on wood as a building material. Where traditional timber reaches its limits, engineered wood products offer new possibilities for future proof constructions.

For more than 35 years, STEICO has been refining the natural material wood into innovative high-tech materials for timber construction. While retaining the positive properties of wood as a natural product, the result is the unique STEICO construction system: ecological, healthy to live with, innovative.

Laminated Veneer Lumber (LVL)

STEICO LVL (Laminated Veneer Lumber) is one of the most resilient wood-based materials available. Whether in modern timber construction or for industrial applications: STEICO LVL impresses with its strength, resilience and dimensional stability.

STEICO LVL consists of several layers of approx. 3 mm thick softwood veneer glued together. This creates an almost homogeneous product with the highest strengths - much more resilient than naturally grown wood.




The concept of the I-joists is simple: High load-bearing capacity - less material. Two LVL flanges are joined by a specially developed hardboard. This creates a very load-bearing joist that is significantly slimmer than a solid beam. Slimmer load-bearing structures in the roof and walls offer more space for insulation materials and thus increase energy efficiency with the same component thickness.


Wood-fibre insulation materials

STEICO manufactures an extensive range of wood fibre insulating materials from fresh coniferous wood - from façade insulation and flexible cavity insulation to sarking boards. Wood fibre insulating materials not only protect against cold in winter, but also against heat in summer. They offer safety from wind and rain and, due to their diffusion openness, a high level of moisture protection.


Air injected insulation

STEICO air injected insulation is made from natural wood fibres. STEICO air-injected insulation is convincing in terms of quality, cost-effectiveness and outstanding insulating properties. Permanent settlement resistance and simple processing are the distinguishing features of these insulating materials.


STEICOmulti sealing system for the building shell

A tight building shell is an essential prerequisite for energy efficiency and functionality. The STEICOmulti sealing system is the comprehensive complete system for air and vapour sealing as well as weather protection. With the accessories such as adhesives and sealants, the connection of the membrane range to each other and to bordering building components succeeds safely and reliably.

Wall and roof constructions with the STEICO Building system

CO2 saving wall constructions

STEICO wall constructions are particularly energy-efficient and make a significant contribution to climate protection through CO2 storage.


Roof constructions which protect against cold AND heat

STEICO roof constructions combine energy efficiency with a healthy indoor climate. They offer the leading summer heat protection of all common insulation materials.


STEICO quality - independently certified

PEFC (Programme for the Endorsement of Forest Certification Schemes)

The PEFC certification (Programme for the Endorsement of Forest Certification Schemes) certifies that STEICO only uses wood from responsible forestry. You can find more information about STEICO certification at


IBR (Institut für Baubiologie in Rosenheim)

The IBR is one of the most respected testing institutes in Germany. The IBR test seal certifies that STEICO products are harmless in terms of building biology – they contribute to healthy homes and a feeling of well-being in the home.

IBU (Institut Bauen und Umwelt)

The Institute for Building and the Environment (IBU) prepares environmental declarations (EPDs) of eco-label type III in accordance with ISO and CEN standards. With the preparation of the EPDs, STEICO provides comprehensive information on the environmental impact of the ecological products over their entire life cycle.


The Keymark certification stands for the high quality of the STEICO range. The uniform European certification mark for standardised products documents the compliance of products with European norms and quality standards.


The STEICO construction system is certified as a component according to the standards of the Passivhaus Institute Dr. Wolfgang Feist. This means that the planner can draw on a large number of defined construction details. This means that passive houses can be built particularly easily and economically with the STEICO construction system.
