Natural Anhydrite Used for Soundproofing by Rigips
In the latest issue of the General Construction Journal (34/2025), a new innovation in building materials has been introduced: the Rigidur screed elements. Manufactured by Rigips, a brand under Saint-Gobain, these elements have been designed to meet sound, heat, and fire protection requirements.
The Rigidur screed elements, when combined with the sound insulation fill from 30 mm, achieve a fire resistance class F90. This non-combustible material falls under building material class A1, ensuring safety in construction.
One of the standout features of these elements is their ease of use. They can be laid quickly and cleanly, without the need for screed honeycombs, a binder, or subsequent compaction by tamping. This makes the installation process more efficient and less messy.
For wooden beam ceilings, which typically offer minimal sound protection, the Rigidur screed elements provide a significant improvement. With a construction height of 100 mm, this combination results in an impact sound insulation value of 27 dB.
The leveling layer of the Rigidur screed elements is settlement-stable at fill heights of 15 to 150 mm, allowing for the compensation of floor unevenness. This feature, combined with the interlocking property of the material when distributed and leveled, forms a mechanically bonded leveling layer.
The Rigidur screed elements are also versatile in terms of floor coverings. According to the processing guidelines as tested combinations, all common floor coverings can be used with these elements.
Moreover, the laying of cables and pipes in the floor is possible with this combination. This makes the Rigidur screed elements a practical choice for modern construction projects.
Rigips recommends using Rigidur sound insulation fill, a sound insulation mat with Isover Akustic EP 3 insulation boards, and Rigidur screed elements for improved impact sound insulation. This recommendation underscores the company's commitment to providing comprehensive solutions for sound insulation needs.
While no new information was provided about the bulk density, the material's suitability for wooden beam ceilings, non-combustibility, interlocking property, settlement-stability, or the requirement for specific sound insulation mats and screed elements, the General Construction Journal 34/2025 marks an exciting development in the world of building materials.
For those interested in staying updated on this topic, it is recommended to follow Rigips and related publications for future announcements and developments.
