fermacell® screed panels with felt fibre insulation
Airborne and impact sound – for solid and lightweight ceilings.
fermacell® screed elements with 9 mm felt fibre insulation boards reduce airborne and impact noise and are suitable as a dry screed for the renovation and modernisation of existing buildings as well as for new builds – on both solid and lightweight ceilings. The felt insulation made from recycled synthetic fibres supports sustainable construction; the F 60 classification allows for enhanced fire protection within the structure. Installation is carried out using a dry method and ensures the screed is ready for finishing quickly.
fermacell® screed elements with felt fibre insulation boards can be laid quickly and cleanly as part of a dry floor system and are ready for finishing in no time. The insulation board helps to reduce construction times in renovation, modernisation and new-build projects – on both solid and lightweight ceilings.
The compact tiles make installation easy; the surface can be walked on immediately and is ready for covering in no time.
The structure remains completely dry, with no additional construction moisture; subsequent trades can begin work immediately without any drying periods.
Low installation heights and low weight help to improve sound insulation in floor structures on solid and lightweight slabs.
The insulation board made from recycled synthetic fibres incorporates recycled material into the structure and supports sustainability goals.
High sound insulation
fermacell® screed panels with felt insulation are designed for sound-insulating floor structures and can be used in both renovation and new-build projects on solid and lightweight floors.
Excellent impact sound insulation for lightweight and timber-beam ceilings: Felt fibre insulation has excellent vibration-damping properties and is particularly suitable for renovation projects involving surfaces that are acoustically sensitive or prone to vibration.
Suitable for specific applications:
Suitable for dry rooms in zones 1, 2 and 3, e.g. offices, medical practices and corridors without heavy equipment – a tried-and-tested solution for refurbishment projects and selected new-build applications.Fire protection in a certified structure up to F 60:
In certified designs, fire resistance ratings up to F 60 are possible. Higher ratings can be achieved by incorporating additional system components.

FAQ
You can find clear answers to the most frequently asked questions in our FAQ section.
Insulation materials used for additional thermal and sound insulation, as well as for levelling the surface beneath fermacell® screed elements, must be approved by fermacell® James Hardie®. Our approved insulation materials possess the necessary strength and are tailored to the properties of the screed elements and the required load-bearing capacity. A list of suitable insulation materials can be found here.
Further information on impact sound insulation can be found in the handbook "fermacell™ Floor Systems – Planning and Installation" and in our list of insulation materials. For exposed timber beam ceilings, the fermacell™ honeycomb insulation system is recommended, amongst other solutions, for effective impact sound improvement.
Standard formats
Tiles and natural stone slabs with a maximum edge length of 330 mm may generally be used on all fermacell® screed elements.
If impact sound insulation boards made of mineral wool or fermacell® screed elements laminated with mineral wool are used, natural stone or terracotta tiles are not permitted.
Tiles are laid using the thin-bed method on fermacell® gypsum fibre screed panels. When using fermacell™ Flex adhesive, a primer is not required. Tiles can be laid on fermacell® Powerpanel TE using either the thin-bed or medium-bed method. When using fermacell™ Flex Adhesive, a primer (e.g. fermacell™ Deep Primer) is required.
Large-format tiles
fermacell® screed elements are suitable for laying stoneware tiles of any size. Certain specifications must be strictly adhered to during installation. Further information on this can be found in the tile list.
Further necessary information can be found in our handbook: "fermacell®™ Floor Systems – Planning and Installation", as well as in the document: "Installation Guidelines for Tiled Flooring on fermacell Floor Systems". Only approved systems may be used for bonding. Please refer to the same document for further guidance.
fermacell® screed elements are suitable as a substrate for the direct bonding of multi-layer parquet in accordance with DIN EN 13489 (e.g. pre-finished parquet elements) and mosaic parquet in accordance with DIN EN 13488. The latter must be laid in a pattern (e.g. herringbone or cube pattern), as this allows the parquet floor to expand in different directions in the event of swelling.
Mosaic parquet must only be installed in a different direction or using other solid wood species and types of parquet with the adhesive manufacturer’s approval. You can also find information on parquet adhesives in our list of recommendations.
Further information can be found in our handbook: "fermacell® Floor Systems – Planning and Installation".
A variety of resilient floor coverings can be laid over fermacell® screed elements, such as carpet, laminate, cork, PVC, linoleum, elastomer and LVT design flooring.
You can find more detailed information on this in the technical documentation: "Installation guidelines for resilient floor coverings on fermacell™ floor systems".
Thanks to the stepped joint, fermacell® screed elements can be used to create a secure (mechanical) bond even in the area of doorways.
