Ext. wall element with timber cladding


FinnFrame-Bausystem is a Lightweight construction system with high energetic efficiency. Finnjoist, I-joist are wood-based composite columns with an I-shaped cross-sections for structural applications. The flanges are made of LVL and the web of OSB, which are glued together with structural glue. The Finnframe Bausystem enables complete solutions based on the Finnjoists, especially for energy-saving construction. High insulated wall structures, with almost thermal bridge-free construction details offer a convincing energy saving solution - from KfW funded, high efficiency houses to the Passive House Standard.

Key benefit

Combination of lightweight, strength, straightness and easy to transport and assemble for highly energy efficient buildings.

Ecological values

Kerto LVL is an environmentally friendly and engineered wood product that can be used as a construction material that stores carbon into the buildings. Wood as a building material - When choosing the building material for energy-efficient houses, the topic of CO2 savings is of paramount importance. Wood meets this requirement in a very special way, since it is even CO2 neutral. This means that it absorbs just as much CO2 When it grows as it releases after use. In principle, wood stores CO2 during its use, which would otherwise contribute to global warming. No other building material can do that.
