ROCKWOOL has published a whitepaper exploring how to identify and mitigate fire risks for flat roofs functioning as additional social or practical spaces of a building, including for solar installations.
The Flat roofs: The functional fifth façade paper explores the fire safety implications of modern multifunctional roofs and discusses best practices for identifying and mitigating the risks. It also explains the role of the guidance provided in approved documents, including Approved Document B (ADB) for fire safety, and examines potential limitations of such advice for non-standard flat roof circumstances and scenarios.
Lisa Stephens, Product Manager – Building Envelope, ROCKWOOL UK, said:
While the use of flat roofs as functional spaces is not a new concept, the practice has become more and more popular in recent years, especially in increasingly crowded urban areas. Now, flat roofs don’t just house plant and building services but energy efficiency infrastructure and social spaces too.
The information in the whitepaper will help those involved in the design and installation of flat roofs to make responsible choices when selecting materials to enable a modern flat roof to be multifunctional, safe and long-lasting. It offers practical advice to simplify specification whilst going above and beyond legislative requirements.
This whitepaper considers implications such as greater footfall and the impact of penetrations from building services and cabling on compartmentation and fire resistance.
