Edilteco® France's Deltivoutain + CI entrevous receives technical advice from CSTB

"DELTIVOUTAIN + CI" - for Integrated Corrector - is an interjoist with an integrated switch to reduce thermal bridges. Patented, this solution now benefits from a Technical Assessment from CSTB issued by the Specialized Group n ° 20 “Special insulation products and processes” and the Specialized Group n ° 3.1 “Floors and floor accessories” which respectively examined this process. .

This Technical Assessment, a reference document for construction professionals, certifies the correct design of the interjoist, its compliance with the requirements of each site, and guarantees the durability and efficiency of the thermal bridge corrector.

An ingenious system

Usually, breakers are independent elements, additional parts to the interjoists that professionals add to their stock. To simplify this, DELTIVOUTAIN + CI has been designed with an integrated breaker on the underside and breakable, so as to facilitate stock management and site preparation.

Efficient but above all very functional, the DELTIVOUTAIN + CI integrates from its manufacture a breakable thermal bridge corrector (UP 0,27) on the underside. This breaker is easily broken by hand.

Perfectly cut to the shape of each interjoist, the breaker is then attached to the upper part of the slab.

Designed in polystyrene (PSE), once implemented, the breaker will reduce the thermal bridge of the connection between the floor and the wall in the case of interior insulation.

The breakable breaker on each interjoist corrects the thermal bridge created in particular by the continuity of the concrete elements of the slab towards the wall chaining. It separates the current part of the floor with that of the peripheral chaining and the local interruption of the distribution slab over all or part of its thickness.

If the use of the breaker is not necessary, the breakable part remains in place and does not interfere with the implementation of the interjoist. This innovative concept of a “2 in 1” product allows craftsmen to avoid having to manage a stock of breakers on their site and generates much less waste.

Quick and convenient implementation

The implementation of DELTIVOUTAIN + CI is similar to that of conventional polystyrene interjoists, but more economical because it does not require peripheral beams and does not require false centers.

Indeed, the starting interjoist is a complete interjoist, not cut, which arises on the edge of the floor. The breakable breaker will be positioned above the interjoist so as to match the chamfer and ensure perfect correction of the thermal bridge in the longitudinal direction, on the edge of the floor. It is therefore not necessary to install a joist on the periphery of the floor as when using “traditional” longitudinal breakers.

In the transverse direction, in an identical manner, the breaker breaker will be cut to be adapted to the width of the interjoist, in order to just cover it. It will be positioned on the upper face to ensure a correction of the thermal bridge at the end of the floor.

In order to guarantee the maintenance of the mechanical performances, the interjoists have a sufficient body thickness. In the end, only one cutout will be necessary for the installation of the arrival interjoist, which like the starting one, will be placed on the edge of the floor, without adding a joist.

The use of plastic anchors will be necessary to ensure the blocking of the thermal bridge correctors during the pouring of the concrete of the slab.

The delivery of the joists is systematically accompanied by an installation recommendation plan which provides the information necessary for the installation of the breakers.

Intended for buildings and individual houses with crawl spaces, the DELTIVOUTAIN + CI will make it possible to provide both the formwork of the compression slab and the insulation of the floor. Lightweight, it is easy to install and effectively reduces thermal bridges for new work but also for renovation work.

Its qualities are numerous, but its major attraction lies in its both practical and economical aspect which protects building professionals from a double stock management of slabs and breakers and offers them the economy of structural elements that have become unnecessary.
