Recycled Tyre Rubber Enhances Acoustic Insulation in Timber Frame Buildings

Incorporating recycled ground tyre rubber (GTR) into lightweight timber frame systems significantly improves their acoustic insulation performance.

Buildings · 2023

Key Findings

01Introducing a GTR layer consistently improved the acoustic performance of all tested lightweight timber systems.
02Different forms of GTR (granulate, rolls, sheets) and their integration with other insulation materials yielded varying degrees of acoustic enhancement.

Application

Design takeaway

Integrate recycled ground tyre rubber into the design of lightweight timber frame systems to enhance acoustic performance and promote material circularity.

How to apply

When designing timber-framed buildings, consider incorporating layers of recycled tyre rubber granulate, rolls, or sheets within the wall cavities, potentially in combination with traditional insulation materials, to improve soundproofing.

Project actions

01When researching materials, look for those that solve multiple problems, like waste reduction and improved performance.
02Consider how different forms of a recycled material might affect its application and performance.

Method & Evidence

AimTo investigate the effectiveness of recycled ground tyre rubber (GTR) in improving the acoustic insulation of lightweight timber frame building systems.

MethodExperimental comparative analysis

ProcedureThree types of GTR products (granulate, rolls, sheets) were integrated into lightweight timber sandwich systems, with variations in thickness and density. These systems were tested alongside other sound-absorbing materials (mineral wool, cellulose, wood fibre). Acoustic performance was evaluated by measuring sound pressure level differences in a custom transmission chamber and by determining the sound reduction index in an accredited laboratory for selected specimens.

ContextBuilding construction, sustainable materials, acoustic engineering

Variables

IVPresence and form of recycled tyre rubber (granulate, rolls, sheets), thickness and density of GTR, combination with other insulation materials.

DVAcoustic performance (sound pressure level difference, sound reduction index).

CVLightweight timber frame system construction, type of sound-absorbing materials used alongside GTR, testing environment (transmission chamber, laboratory).

Strengths & Limitations

Strengths

+Directly addresses a known weakness in timber construction (acoustic performance).
+Utilizes a problematic waste material (tyre rubber) for a beneficial application.

Limitations

The acoustic performance may be influenced by the specific construction details of the timber frame and the quality of the GTR material used.

Reliability & validity

The use of an accredited sound transmission laboratory for measuring the sound reduction index enhances the validity of the findings. However, the initial qualitative assessment in a custom-made chamber might have limitations in direct comparability to standardized lab results.

Think critically

Beyond acoustic performance, what other potential benefits or drawbacks (e.g., fire safety, thermal bridging, cost) might arise from incorporating recycled tyre rubber into building structures?

Design Principles

"Waste materials can be re-engineered to provide enhanced functional performance in new applications."

This research offers a dual benefit: it addresses the environmental challenge of waste tyres while simultaneously enhancing the comfort and performance of timber buildings. Designers can leverage this insight to create more sustainable and acoustically superior structures.

What This Means for Your Design

Using old tires in wooden walls makes them quieter.
