Extremely challenging locations

Rigidur H gypsum fibreboards are conventionally used in partition walls with extremely high requirements in terms of robustness – with single- and double-layer panelling through to double stud partition systems. Thin pre-fabricated walls with a single layer of Rigidur on each side illustrate just how effective Rigidur is in terms of preventive fire safety and sound protection. A panelling thickness of just 10 mm on each side is sufficient to meet the requirements of fire resistance category F 30. Depending on the wall construction, a double layer of 12.5 mm Rigidur boards as panelling is sufficient to achieve fire resistance category F 90. With a value of Rw,R = 62 dB, this type of construction also exhibits excellent sound protection properties.

Rigidur H gypsum fibreboards were used throughout a school building in the Hoch­sauerland region. Fitted in all staircase and corridor areas, the tough and highly scratch-resistant boards are sufficiently hard-wearing to cope even with the most chaotic school days. Thanks to their extremely high strength, the robust wall constructions can easily withstand day-to-day stresses, while their extra hard, scratch-resistant and smooth surfaces mean that they show little sign of these stresses, even after a number of years.

Thanks to the air-purifying effect, Rigidur H is also contributing to an ideal learning climate in school buildings.

Extravagant design

The standard version does not always have to be used – the latest architectural visions are proof of this. However, in drywall construction, use of the “right standard” is in­dispensable. Rigidur H boards ensure that walls and ceilings meet fire safety requirements and can easily be cut to shape directly on the construction site thanks to their suitability for precision processing. Recommended as an environmentally friendly construction material, using Rigidur H in your reception area shows you feel it is important not only to look after your own health, but also that of your guests. This reception area at Rheinzink GmbH & Co. KG is a timber structure. The exterior is clad with zinc and the interior panelled with Rigidur H.

There are virtually no right angles and the only thing the various walls have in common is the choice of panelling material, with around 1,000 m2 of Rigidur H boards used. Rigidur H boards were a logical choice for the extraordinary shape of the building designed by renowned architect Daniel Libeskind as they could be precision cut and joined together at tolerances in the millimetre range. It was even possible to combine aesthetics with fire safety: In order to achieve fire resistance category F 30, the ceiling and the walls were panelled with Rigidur H.

Modern construction and healthy products form an exceptional symbiosis.

Rigidur Flooring Elements with historical roots

Rigidur Flooring Elements offer a particularly efficient solution for maximizing comfort in both solid and wooden beam ceilings in old and new buildings. These dry floor screeds are extremely durable thanks to their extra hard surfaces and can be subjected to high single and area loads. They can be used in a wide range of applications and a wide range of Rigidur Flooring Elements is therefore available. Depending on sound protection and fire safety requirements, Rigidur Flooring Elements can also be supplied with special laminations made of mineral wool, soft wood fibres or polystyrene.

Rigidur Flooring Elements offer reliable fire protection up to category F 120 for the supporting elements in floors and/or ceilings. Their low weight per unit area of only approx. 25 kg/m2, also makes them an attractive option for use in ceilings with a low load-carrying capacity. A particularly strong argument in their favour is their short installation time thanks to the dry laying process – unlike wet screeds, no long drying times need to be taken into account and any standard type of final coating can be applied to the dry floor screed after a maximum of 24 hours.

The special advantages of Rigidur Flooring Elements have even been utilized in conversion and renovation work in previously unused historic rooms at the Herrenchiem­see palace. As the old wooden ceilings were classified as having a calculated load of 5 kN/m2,the decision was taken in favour of Rigidur Flooring Elements due to their low weight per unit area and quick processing time. Any unevenness in the basic structure was levelled out with Rigidur levelling compound and Rigidur 25 Flooring Elements then installed over an under-floor heating system. After adding an additional layer of Rigidur H 10 mm boards, the Rigidur dry floor screed was then covered with parquet flooring in keeping with the restored rooms which surely even Ludwig II would have been pleased with.

For the ultimate in performance, professionals rely on Rigidur screed elements.
