with brick, it’s easy to make sustainable

Discover how brick contributes to the thermal performance of the building envelope. Reinforced Bbio: constructive solutions proven and known to professionals.

The brickmakers are convinced of the importance of the building’s energy sobriety and have long been committed to improving the thermal performance of bricks: in 20 years, their thermal resistance has been multiplied by 3.

The studies carried out show that the brick R=1 combined with a 12 cm th30 insulating lining thickness in ITI (Interior Thermal Insulation) meets the requirements of RE2020 in the vast majority of cases and allows the achievement of a Bbio on average at -10%/-15% compared to Bbiomax.

To meet more complex configurations, each manufacturer offers ranges of 20 cm bricks of R up to 1.5, thus making it possible to optimize the thickness of added insulation. Heat losses from the walls, low floors and roofs of new buildings are reduced by a reinforcement of insulation and appropriate treatment of thermal bridges.

For walls, the simple and effective answer that exists among all bricklayers is the brick with thermal resistance R ≥ 1. The R=1 m2.K/W brick is already commonly used and its implementation is mastered by companies.

Associated with the brick, many accessories ensure a global and homogeneous treatment of the envelope and particularly of the thermal bridges of the wall:

– insulated slats at the end of the floor,
– rolling shutter boxes,
– lintels,
– shuttering brick…

Gain of SHAB: the bonus of the insulating brick

The insulating structural brick of R≥1 is a load-bearing element whose intrinsic thermal performance also allows to gain living space compared to standard masonry (3% minimum, with a brick of R=1) by limiting the increase in associated insulation thicknessat constant wall R.
