Summary for decision-makers

EDILTECO France launched LA CHAPE XXa Acoustique at the Batimat 2024 trade fair. This new lightweight, ready-to-use screed incorporates an acoustic underlayer that reduces the weight of structures by up to 50% compared to traditional concrete and improves the acoustic performance of buildings, meeting the requirements of sound comfort and energy efficiency.

Composed of expanded polystyrene beads, recycled rubber granules, and fibers, LA CHAPE XXa Acoustique offers optimal sound insulation (20 dB reduction per 5 cm thickness). CE certified and rated A+ for indoor air emissions, it is suitable for new construction and renovation, exclusively for indoor use.

EDILTECO unveils LA CHAPE XXa Acoustique, a lightweight and high-performance solution for long-lasting interior sound insulation.

A major acoustic advance for the interior building

Five years after the distinctive launch of LA CHAPE XXs at the Batimat trade fair, EDILTECO® France returns this year with a new innovation in the field of lightweight screeds. It is at the 2024 edition of the Batimat trade fair that EDILTECO France presented its latest advance: a complex solution integrating an acoustic underlay.
This new lightweight screed, called LA CHAPE XXa Acoustique, not only offers a significant reduction in the weight of structures, but also improves the acoustic performance of buildings, thus meeting the growing needs of professionals in the sector in terms of sound comfort and energy efficiency.

A new acoustic complex

An innovative solution, LA CHAPE XXa Acoustique is an acoustic complex combining an acoustic underlay and a ready-to-use lightweight screed. Compatible with all types of floor coverings, this complex is designed to significantly improve sound insulation.
LA CHAPE XXa Acoustique is lightened thanks to expanded virgin polystyrene beads, with controlled granulometry, coated with an additive (diameter of 2 to 3 mm). Its composition also includes fibers and SBR rubber granules (from recycled tires), with controlled granulometry, associated with selected special binders.
This fiber screed thus offers optimal mechanical properties, ideal for the renovation of difficult or sensitive supports.
Thanks to this composition, LA CHAPE XXa Acoustique makes it possible to lighten structures with a weight saving of up to 50% compared to traditional concrete.

Optimal sound insulation

Designed for indoor applications only, LA CHAPE XXa Acoustique combined with its underlay ensures complete separation of the screed from its support, walls and crossing elements. This allows a significant reduction in the transmission of impact noise. Thus, this acoustic complex effectively insulates and treats the different types of supports present in apartment buildings and individual houses. Thanks to its acoustic attenuation performance (20 dB for a thickness of 5 cm), LA CHAPE XXa Acoustique effectively absorbs impact noise such as heels, falling objects and moving furniture... It is an ideal solution for all new construction or renovation work.

This innovative screed is CE marked according to NF EN 13813: CT-C12-F3, ensuring its compliance with current quality and safety standards. Its reaction to fire is classified A2fl-s1, guaranteeing optimal safety.
In addition, it displays a level of emission of volatile substances in the indoor air of class A+ "very low emissions", in accordance with the decree of 19/04/2011, which makes it a solution that respects the environment and the health of the occupants.
