Thermobloc

50 years of experience behind a new way of building.

One block. The whole wall.

Thermobloc is an insulated concrete form block with an integrated stone finish. Stack the blocks, pour concrete inside, and the wall is done: structure, insulation, interior and exterior finishes, in a single step.

Exploded view of a Thermobloc block, layers numbered 1 to 4. Thickness: 16 in.; length: 48, 24 or 16 in.; height: 12 in.

From outside to inside

  1. Exterior finishA 2-inch layer of concrete, in the finish and color of your choice.
  2. Continuous insulation6 inches of EPS type 2 placed on the outside of the structure: no thermal bridging, and the structural concrete stays protected.
  3. Reinforced concrete coreThis is where the 30 MPa concrete is poured. Reinforcement is installed according to the engineer's recommendations, using composite rebar that creates no thermal bridging.
  4. Interior finishA finish and color independent of the exterior. This layer also serves as the interior formwork.
