Acoustic insulation solutions for timber buildings

High-performance, sustainable solutions designed to improve acoustic comfort in floors, suspended ceilings and walls in timber buildings, for both new-build and refurbishment projects.

Timber construction combines lightweight structures, fast construction times and design flexibility. However, the lower mass of timber structures makes effective acoustic design particularly important, especially when it comes to limiting the transmission of impact and airborne noise.

Isolgomma offers dedicated solutions for different building elements, including traditional timber beam-and-board floors, CLT floors and lightweight walls. By combining efficient floor and wall build-ups with high acoustic performance, these systems help create quieter, more comfortable indoor environments. Our technical catalogue for timber structures demonstrates how impact noise can be effectively reduced, even where installation thickness is limited.

Why acoustic insulation is essential in timber construction

Timber structures have a lower mass than traditional construction systems and therefore require a specific approach to acoustic design.

Achieving high acoustic performance means considering the entire building assembly, combining resilient materials, acoustic insulation elements and decoupling systems to minimise the transmission of impact and airborne noise.

These solutions can be integrated into both CLT systems and beam-and-board structures, making them suitable for new-build construction and the upgrading of existing buildings.

Where to use acoustic insulation solutions in timber construction

Residential buildings

Solutions to improve acoustic comfort between flats, rooms and different floors of a building, reducing noise transmission by means of lightweight structures.

New-build construction

Systems compatible with contemporary buildings featuring timber floors and walls, from traditional beam-and-board structures to modern CLT systems.

Accommodation establishments

Advanced acoustic insulation solutions designed to reduce noise transmission between adjacent spaces, enhancing privacy and guest comfort in hotels, resorts, bed and breakfasts, aparthotels and luxury accommodation.

Schools

Acoustic insulation solutions for classrooms and communal areas, suitable for educational buildings of all types, from nurseries to universities. They help provide the acoustic comfort students and teachers need to concentrate, communicate and learn effectively.

The benefits of acoustic insulation in timber buildings

High impact noise insulation performance

Integrating resilient layers into floor assemblies helps reduce the transmission of noise caused by footsteps and impacts, improving acoustic comfort between different storeys.

Compatibility with underfloor heating systems

Acoustic solutions can also be integrated into floor assemblies with underfloor heating systems, maintaining high performance and the functionality of the overall build-up.

Faster construction

A high degree of prefabrication and the use of dry-assembled systems help streamline construction work and reduce on-site installation times.

Greater sustainability

Using recycled materials or materials with a reduced environmental impact makes it possible to combine acoustic performance with construction efficiency. The Isolgomma timber structures catalogue features solutions made with up to 90% recycled material.

Acoustic insulation solutions for timber floor structures

Isolgomma solutions for timber floor structures are designed to reduce impact noise in beam-and-board and CLT floor structures.

Depending on the construction system, building assemblies can be designed with a traditional or dry screed, incorporating resilient materials that decouple the floor finish from the load-bearing structure and improve the acoustic performance of the floor structure.

Timber structures

Beam-and-board floor structure with traditional screed

When to choose this solution

Ideal for upgrading traditional timber floors where improved acoustic performance is required through a floating screed system.

Installing a resilient acoustic insulation layer beneath the screed helps decouple the flooring from the supporting structure, reducing impact noise transmission.

Ideal for

  • Residential buildings
  • Traditional timber floor structures
  • Projects requiring high performance

Key benefits

  • Improves impact noise insulation
  • Decouples the floor finish from the structure
  • Improves the acoustic performance of the floor structure
  • Maintains the construction flexibility of the timber system

CLT floor with conventional screed

When to choose this solution

Suitable for buildings with CLT floor structures incorporating a conventional sand-and-cement screed.

Integrating an acoustic insulation layer into the floor assembly improves its performance against impact noise while enhancing overall indoor acoustic comfort.

Ideal for

  • New-build timber construction
  • CLT buildings
  • Residential buildings

Key benefits

  • Improves impact noise insulation
  • Enhances acoustic comfort in the room
  • Integrates the insulation into the floor structure build-up
  • Optimises the acoustic performance of CLT floor structures
Timber structures

Traditional timber beam-and-board floor with dry screed

When to choose this solution

Ideal when acoustic insulation needs to be improved in an existing timber floor while minimising the use of wet construction methods.

A dry floor assembly provides a practical solution for lightweight timber structures and is particularly suitable for renovation and refurbishment projects.

Acoustic insulation solutions for suspended ceilings

Our ceiling solutions are designed to improve the acoustic performance of timber floors by treating their underside, helping reduce noise transmission between different storeys.

Depending on the available space and structural characteristics, directly fixed or suspended ceiling systems can be used.

Vibration isolation components, sound-absorbing materials and acoustic panels help decouple the ceiling lining from the floor structure. These solutions can also be combined with under-screed acoustic insulation systems to further improve the performance of the entire floor assembly.

Timber structures

Directly fixed ceiling system

When to choose this solution

Ideal when acoustic insulation needs to be improved on the underside of a timber floor while keeping the overall ceiling build-up as thin as possible.
