New Promat slab: even more insulating

Suitable for use in renovation projects as well as in the construction of energy-efficient buildings, the Promat®-SYSTEMFLOOR 28WF tile has excellent acoustic and thermal insulation qualities. Installed at floor level, it significantly reduces impact noise or the movement of furniture.

Promat®-SYSTEMFLOOR 28WF: a floating dry screed with optimal insulation performance

Promat , a leader in the manufacture and marketing of high-performance sheet and sprayed insulation, is launching the Promat®-SYSTEMFOOR 28WF process , a new generation acoustic and fire-resistant floating dry screed, ideal for all types of structures (including Low Energy Buildings).

This ingenious system is installed on a wooden floor or a RC slab and provides additional acoustic and thermal insulation. Thus, with excellent soundproofing in terms of impact noise (moving people, furniture, falling objects, etc.) and airborne noise (conversations, television, etc.), it improves sound reduction.

Promat®-SYSTEMFOOR 28WF consists of 2 layers of stabilized magnesium mineral boards (Masterboard® M), glued together (2 x 9 mm) and a 10 mm layer of wood fiber fixed under the boards.

Supplied in 1200x600x28mm panels, it is designed to create a perfectly flat, insulating, floating screed on slabs or floors. Non-combustible (classified A1), it offers high fire resistance against top-down fires on wooden floors (REI 60) ( test report in progress).

Each board has a 50 mm reduction in width and length for a uniform, rigorous and consistent rebate assembly. This feature and its lightness (less than 15 kg) make it a particularly pleasant material for installation.

Its wear-resistant, smooth and robust surface resists shocks, punching, friction, humidity, mold, etc. and can be finished with carpet, parquet, or tiles.

The advantages of the Promat®-SYSTEMFLOOR 28WF:

• High acoustic performance

• Low thickness

• Simple implementation

• High resistance to punching

Implementation characteristics:

• Step 1: Decouple the future Promat®SYSTEMFLOOR 28WF screed from the walls and posts by installing a decoupling strip which will ensure the independence of the screed and limit lateral acoustic transmission,

• Step 2: Remove the battens that rest against the walls so that the thickness of the Promat®SYSTEMFLOOR 28 WF remains the same at all points,

• 3rd step: during installation, each board will be secured to the next by the simultaneous application of a double bead of glue in the rebate (Promat®SYSTEMFLOOR glue). Dimensional adjustments are very easy to make by simply cutting using conventional tools (panel or circular saws).

The inertia of the material is almost zero and the robustness of its assembly/bonding allows the installation of partitions a few hours later.

Application case of Promat®-SYSTEMFLOOR 28WF:

Promat®-SYSTEMFLOOR 28WF was designed to guarantee easy installation, without any difficulty or risk of error, as Alain Bartoux, Development Engineer at Promat, can attest. During the construction of new social housing in Caen, 200 m² of Promat®-SYSTEMFLOOR 28WF were installed in the bedrooms and hallways to receive parquet or linoleum flooring. Alain Bartoux emphasizes that the installation "was quick and easy because the installation instructions are just as simple!"

Promat®-SYSTEMFLOOR 28WF, an acoustic solution that is quick and easy to implement, is positioned as a major component of comfort, safety and floor insulation for new constructions or during renovation operations.
