What materials make up a self-build block?
Gablok insulated wooden blocks are made of OSB wood and EPS insulation.
OSB: wood for Gablok insulated blocks
OSB is a type of wood made from strands of wood and natural resin. It does not contain formaldehyde.
The wood chips and strands are compressed to form the 18 mm thick OSB.
OSB wood has the distinction of being stable. The categories used are classes 3 and 4. The wood of which it is made does not expand or contract any further. The timber-frame building will therefore not move over time.
EPS: insulating part of the wooden blocks
EPS stands for Expanded PolyStyrene. The polystyrene beads are placed in an oven. This contact with heat allows the polystyrene to expand to 40 times its size and volume.
It is then poured into moulds and compressed to form EPS.
The insulation consists of 2% material and 98% air. This gives it a super-insulating energy performance.
The combination of wood and EPS means that the self-build blocks are perfectly insulated.
