Ecoframe Concept

All the materials we use are ecological,
mostly wood-based.
Needless to say, there is no plastic used in
Ecoframe houses.
The timber-frame wood is sourced from local, sustainable forests.


These are key examples, as a full list would be too long. As always we are open to customer wishes.



Wood is a renewable resource and in its basic form makes up a large percentage of an ecoframe house.
Examples include studs, outer paneling, inner paneling, spacers, and skirting.


Oriented Strand Board (OSB) is produced by pressing small pieces of wood together. It uses almost any wood and produces a hard, strong board. We use M1certified eco-boards produced without formaldehyde. OSB Board is mostly used in the construction, but may also provide inexpensive surfaces, eg in ceilings.


We use blown insulation, either made from paper, or wood. Paper-based is the cheapest but contains relatively much salt as retardent. On the other hand, Ehta's wood chips are 100% wood but slightly less insulation value. The middle road, also in terms of cost, is Hunton's wood fiber.

Of course, even more materials are needed for a whole house, but this gives a good overview. We are always open to customer wishes and suggestions.



We use wood-fiber weatherboards as the outer skin of the insulated volume of the house. The boards are taped and provide a complete windtight skin around the house.


Fermacells fiberboard, pressed from fiber and lime, is a more ecological alternative to gypsum-board that we use for inner walls. It is much denser, thus providing better sound and fire resistance and only requires a single layer.


We source saw, and plane all posts and beams needed for the timber-frame part of an Ecoframe house.
The wood is sourced from local farmers who practice sustainable forestry. The wood, usually 20x20 cm, is dried for a year before further use.


Among other finishes, we use clay, which can be rendered straight onto the Fermacell fiberboards, given a lovely natural finish.

Clay can be used as a paint or a one or two-layer plaster of different coarseness. Clay comes in many colors and shades.
