Homogen80

Structure

Homogen80 is an 80 mm thick softwood chipboard. The board is made up of several layers which therefore achieve an independent mechanical strength. The surface layers also form a good base for direct surface finishes. The boards are produced in sizes up to max. 537 x 203 cm and can be fitted (glued) together to form larger panels by means of tongue-and-groove joints.

Design process

The design is not bound by any production-related module. The project can be designed as required and subsequently divided into elements in conjunction with the manufacturer. The stability and homogeneity of the raw material leaves plenty of scope for cutting elements to almost any size, with openings of virtually any shape.

The system is very similar to traditional solid construction, or rather "heavyweight prefabrication", in respect of its structure, design options and building performance properties. The mass of the chipboard results in a heat storage capacity that creates similar interior climate conditions to a building of solid masonry or concrete.

Loadbearing behaviour: The direction of span is irrelevant.

Shaping: The material can be shaped during the production process.

Applications: The system must be combined with other systems at the floors and roof. The load-carrying capacity of the chipboard as a horizontal flooring element is inadequate over conventional spans.

Facade: It is possible to build a compact facade structure without adding a vapour barrier.

Insulation: The insulation is attached externally.

Surface finish: The surface of the chipboard is such that it can be rendered, plastered, wallpapered or tiled directly. The dimensionally accurate construction is beneficial to carrying out cutting work directly from the drawings.
