Wooden self-build blocks - Belgian insulated wooden blocks

Where are the self-build blocks produced?

The added value of Gablok self-build blocks is that they are made entirely in Belgium. Each block of wood is locally sourced.

From the Herve and Soumagne regions, we were keen to work with local companies to create our self-build blocks for timber frames.

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

Each of these creates a part of the blocks which are then assembled to make the Gablok insulated wooden blocks.

X-PACK and expanded moulded products

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

The base product is in the form of styrene beads. When in contact with water vapour, the beads expand to 40 times their size and volume, without using solvents or other adhesives.

X-PACK then places them in moulds to be compressed and create the insulation for Gablok wooden blocks.

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

Les Gaillettes workshop and insulated wooden blocks

The non-profit organisation Les Gaillettes manufactures our various wooden building materials, including the wooden blocks containing the EPS insulation.

OSB wood consists of a mixture of wood strands and natural resin. The chips (thin strands) are compressed to form the 18 mm thick OSB. The class 3 and 4 OSB used in our blocks does not contain formaldehyde.

The great advantage of this type of wood is that it does not expand or contract any further. There is therefore no risk that it will change shape over time. Your house will remain level.

After assembly, Gablok self-build blocks are delivered on pallets, saving you on-site waste.
