The SIGNUS Guide highlights recycled rubber’s sound absorption and thermal insulation, making it highly applicable in construction
SIGNUS has released a Guide on Circular Materials Using Recycled Tyres in Construction, designed as a technical resource for industry professionals seeking to integrate recycled, high-value materials into construction practices.
This inaugural publication, directed at the construction sector, addresses “Plaster Prefabricated Elements with Rubber” and reflects collaborative efforts under the University-Business Classroom initiative, “Aula SIGNUS.”
The project, initiated in 2023 by SIGNUS in partnership with the Higher Technical School of Building Construction at the Polytechnic University of Madrid, is focused on fostering applied research into the use of recycled rubber from end-of-life tyres (ELT) within the sector.
Laboratory testing indicates that recycled rubber, when included in plaster composites, enhances material properties such as water resistance and offers additional benefits in thermal insulation and sound absorption, supporting the development of more sustainable construction solutions.
The Guide includes:
• Technical characterisation of recycled rubber powder and granules.
• Key parameters for the design of composites with plaster and rubber.
• Laboratory results on developed formulations.
• Information on the recyclability and life cycle analysis of these new composite materials.
With a practical and accessible approach, this publication is intended as a useful tool for architects, engineers, building technicians, and construction companies looking to innovate with more sustainable, circular, and efficient materials.
The Guide can be downloaded here.
