New Prédalle Thermik KP1: The ultimate barrier to thermal bridges

To help them meet this challenge, the prefabrication specialist KP1 is enriching its offer of Prédalles with integrated thermal breakers*, which makes it possible to effectively deal with losses at the junction between floors and facades. It unveils its new Prédalle THERMIK, the most efficient prestressed concrete structural solution on the market.

Thanks to a total break in the floor/façade connection in the load-bearing and non-load-bearing directions, it divides heat losses by four. It makes it possible to obtain a reduced linear thermal transmission coefficient (Psi) of between 0,22 and 0,30 W/m.K for concrete constructions.

These energy savings brought by record and competitive treatment of common floor/façade connections generate other advantages for the site such as the reduction in the thickness of wall lining which thus optimizes the living space, the elimination of the treatment of balcony connections, etc.

The all-in-one answer for RE2020 buildings

Beyond the thermal aspect of RE2020, the Prédalle THERMIK also responds pragmatically to the environmental issue. Made from pre-stressed concrete, in the French KP1 factories, it intrinsically reduces the carbon weight of the building thanks to the reduction in the quantity of materials (concrete and steel) generated by this construction method: carbon gain of 30% compared to a solid slab .

For projects where the carbon impact must be further optimized, KP1 offers the THERMIK Prédalle in its eco-designed IMPAKT IC16 range. It reaches a carbon weight of 16 kg CO2 eq/m2, a gain of 33% compared to a standard reinforced concrete slab.

At the end of its annual Technical Seminar, which ended this Sunday, December 3, the Pôle Habitat FFB unveiled the winners of its 2023 Innovative Housing Challenge. In the “Low carbon structural solutions” category, the Prédalle THERMIK version of the IMPAKT range received the gold medal. A distinction shared with HIBANA, the pilot developer who experimented with this innovative system from both a thermal and environmental point of view.

The solution for all construction sites

The new Prédalle THERMIK is delivered to the site ready to install, with its thermal breakers, its connecting steels and its safety accessories integrated directly in the factory. It guarantees rapid and reliable installation. Its breakers are equipped with a protective cover to protect them from the hazards of the construction site and humidity.

THERMIK Prédalle is available in three floor thicknesses (20, 23 and 25 cm) and covers all the needs of collective housing sites and non-residential buildings insulated from the inside (offices, schools, health establishments, etc.) , whatever the seismic zone. It can be implemented on all floor levels (top of basement, upper floor and roof terrace) and all types of facades (concrete wall, concrete block masonry, brick masonry).
