fermacell® screed panels with wood fibre insulation
Sturdy base. Noticeably quieter. Built to last.
fermacell® screed elements with wood fibre insulation combine high load-bearing capacity with effective impact and airborne sound insulation in floor structures. The integrated wood fibre insulation dampens noise and is made from renewable raw materials. As a dry floor structure, the elements can be walked on quickly and are ready for covering in no time – ensuring efficient construction processes and tested floor structures with defined sound and fire protection.
High fire resistance and great versatility
fermacell® screed elements with 10 mm Wood fibre insulation layers, as a bio-based alternative to dry screed, meet the demanding requirements of modern interior design.
Sturdy and highly durable: Suitable for the renovation and modernisation of existing buildings as well as for new builds. It effectively insulates against airborne and impact noise in both solid and lightweight ceilings (e.g. timber-beamed ceilings).
Fire safety: Tried and tested F 90-Classification for timber-beam ceilings without additional layers when the ceiling surface is exposed to flame.
Compatible with various top layers: Complete freedom of choice when it comes to the final finish, as it is suitable for almost all standard floor coverings, such as tiles, parquet, designer flooring or carpet.
Assembly made easy – save time, maintain quality
The video demonstrates how to install fermacell® screed panels with wood fibre insulation efficiently and precisely – step by step, with practical tips for clean connections, secure joints and a smooth construction process.
fermacell® screed panels with wood fibre insulation are easy and efficient to install and help to reduce construction times in interior fit-out projects. The dry layered construction speeds up the time it takes for the floor to be ready for covering and ensures that installation processes on site remain clear and predictable.
The compact components are quick and easy to lay – and ready for flooring after just one day. Installation takes place without introducing any additional moisture into the structure.
Suitable for uneven or delicate subfloors in older buildings, without the need for complex levelling work.
Low profile heights starting at 20 mm can be combined with significantly lower weight. This makes it easier to use in applications where there is limited headroom and load capacity.
Wood fibre, a bio-based insulation material, is vapour-permeable and helps regulate humidity. As a result, this dry-lay system helps create a comfortable indoor climate.

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.
As wooden floorboards can continue to dry out and shrink, and there is also a risk of knots falling out, a vapour-permeable protective layer must be laid before the levelling compound is applied. In the area of the floorboards, a vapour-permeable underlay may need to be considered before installing the macell™ levelling compound. To reduce impact noise, we recommend installing the 30 mm macell® screed element with wood fibre (2 E 31).
Further information can be found in the manual: fermacell™ Floor Systems – Planning and Installation.

To achieve good airborne and impact sound insulation performance in relatively lightweight, multi-layered timber-beam ceilings, the following options are available:
Increase in the mass per unit area of the rough floor (e.g. using the fermacell™ honeycomb insulation system)
Reducing the stiffness of the impact sound insulation board, e.g. screed elements containing wood fibre or mineral fibre (whilst ensuring that the dry screed retains sufficient compressive strength)
Decoupling the suspended ceiling from the wooden beams (e.g. using a spring-loaded suspension system)
Cavity insulation using fibrous insulation materials (e.g. mineral fibre) in the area of the suspension and between the wooden beams
Further dry screed systems are described in the handbook: fermacell™® Flooring systems – design and installation shown.
Impact sound insulation boards made from wood fibre are significantly stronger than those made from mineral fibre. They retain their strength even when subjected to pressure or walked on during transport, storage and installation.
With mineral fibre impact sound insulation boards, there is a risk that the stabilising adhesive structure of this material will be irreversibly damaged when subjected to stress – for example, from foot traffic during installation – thereby compromising its strength. However, when installed with due care (e.g. using load-distribution boards made of gypsum fibre during installation), mineral fibre boards offer slightly better sound insulation. Mineral wool insulation materials are non-combustible and contribute positively to fire resistance.
In the case of fermacell® panels laminated with mineral fibre at the factory® The use of screed elements reduces the risk of damage, as there is no direct foot traffic during installation.
