Natural Anhydrite Offered for Acoustic Insulation by Rigips
In the latest issue of the General Construction Journal 34/2025, the Rigidur Estrichelemente, a product from the renowned manufacturer Saint-Gobain, takes centre stage. This innovative material, designed to cater to sound, thermal, and fire protection requirements, is making waves in the construction industry.
The Rigidur Estrichelemente is associated with Rigips, a name synonymous with quality in the industry. This material, when distributed and leveled, forms a mechanically bonded leveling layer, providing a solid foundation for various floor coverings.
One of the standout features of the Rigidur Estrichelemente is its settlement-stability. It demonstrates this stability at fill heights ranging from 15 to 150 mm, making it an ideal choice for a variety of construction projects.
The material's special structure and grain size distribution contribute to its unique properties. It is suitable for use in wooden beam ceilings, offering a solution for both new construction and renovation of existing buildings.
The Rigidur Estrichelemente also offers a solution for compensating floor unevenness and accommodating the installation of cables and pipes in the floor. In combination with Rigidur Schalldämmschüttung, it provides a flexible and efficient solution.
The Rigidur Estrichelemente is a non-combustible material, belonging to building material class A1. All variants of the material achieve fire resistance class F90 at 30 mm, ensuring safety and peace of mind for builders and homeowners alike.
The material's bulk density is approximately 1600 kg/m³, making it a practical choice for a wide range of construction projects.
In combination with specific products, the Rigidur Estrichelemente can significantly improve impact sound insulation. For instance, in a timber beam ceiling building, it can provide an improvement of 27 dB at a construction height of 100 mm when used with Isover Akustic EP 3 insulation boards and Rigidur screed elements. The manufacturer of the acoustic filling material responsible for this impressive improvement is ISOVER.
The prefabricated floor elements can be laid quickly and cleanly with the Rigidur Estrichelemente, contributing to the efficiency of construction projects. With its versatility, reliability, and performance, the Rigidur Estrichelemente is undoubtedly a game-changer in the construction industry.
