Wooden self-build blocks - Belgian insulated wooden blocks

Where are the self-build blocks produced?


The added value of Gablok self-built blocks is that they are designed entirely in Belgium. Each block of wood comes from a short circuit.

Coming from the Herve and Soumagne regions in the province of Liège, we were keen to work with local companies to produce our self-build timber-frame blocks.

We are proud to work with qualified teams from Verviers and Battice: X-PACK for the graphite EPS insulating blocks and the workshop ofASBL Les Gaillettes for the OSB structures.

Each company creates a part of the blocks, which are then assembled to make Gablok insulated wood blocks.

X-PACK and molded expanded products

The insulated part of our insulated blocks is made of graphite EPS.

The basic product takes the form of styrene beads. In contact with water vapor, the beads increase in volume by 40 times their size, without the use of solvents or other adhesives.

X-PACK then places them in molds where the beads are compressed to form the insulation of the Gablok wood blocks.

Thanks to this technique, EPS becomes a hyper-insulating material composed of 2% material and 98% of the best existing insulator: air!

Les Gaillettes workshop and insulated wooden blocks

Les Gaillettes ASBL manufactures our various wood building materials, including the wood blocks in which EPS insulation is found.

OSB wood is a mixture of wood strips and natural resin. The chips are compressed to form 18mm OSB. The class 3 and 4 OSB used in our blocks contains no formaldehyde.

The big advantage of this type of wood is that it no longer works. So there's no risk of it changing shape over time, and your house will stay level.

Does the assembly of wooden blocks keep my self-build home level?

Once assembled, Gablok self-build blocks are delivered on bonded pallets, so you don't have to worry about waste on the building site.
