Why do terracotta products reduce thermal bridges?

Each new regulation forces us to rethink our building systems for ever more performance, and today, with the RE 2020, also less carbon impact. Thermal bridges are the sinews of war when we know that they represent 20% of thermal losses in single-family homes, and 18% in new isolated collective *.

Beyond the discomfort in the home, these energy losses cause high heating bills and CO emissions.₂ additional. The more well-insulated a home, the more it will have the capacity to limit thermal bridges, and therefore to keep heat inside the home.

Bio'bric terracotta: a 100% French material that is naturally insulating

The bio'bric construction solutions are made from clay; local renewable resource extracted near 9 production sites across France. Firing clay transforms the material into terracotta and gives it a strong insulating power. The high thermal performance of bricks is linked to their geometry, and in particular their cells. The more complex the geometry of the bricks, the more insulating they are.

Thermal performance in the building envelope

The higher the thermal resistance of the brick and the thermal bridges treated with accessories, the more the building envelope will be insulated. Energy losses will be significantly reduced and this will limit the thickness of additional insulation in the walls.. bio'bric thus offers a wide range of bricks ranging from a thermal resistance of 0,75 to 1,5 m².K / W. They are thus at least 4 times more insulating than traditional non-insulating masonry (Rth = 0,2 m².K / W).

Terracotta accessories for a homogeneous facade

Thermal bridges are often observed at the openings and at the junction of the floors with the facade. They cause problems of discomfort as well as risks of possible deterioration of the construction, such as the appearance of condensation and cold spots. The choice of accessories such as insulated planelles or lintels / terracotta roller shutter boxes makes it possible toobtain a 100% homogeneous terracotta facade and long-lasting performance. bio'bric offers packs combining wall bricks with its terracotta accessories to significantly reduce these breaks in insulation in single-family homes and collective dwellings.

At the start of 2020, bio'bric added the planelle supeRmax to its product range; best performance on the market with a thermal resistance of 1,7 m².K / W. Associated with the special collective brick, the bgv'costo th + (R = 1,5 m².K / W), bio'bric offers the system of excellence for the construction of multi-storey buildings: Ψ L9 = 0,26 W / m².K in concrete floor.
