We have today launched our guide to the use of PIR insulation in flat roofs in England. The guide has been written for specifiers, building owners, main contractors and roofing contractors and offers expert advice on the key aspects affecting the specification of PIR insulation for flat roof applications.

The document provides guidance on how to meet the latest requirements of Approved Document B (ADB) of the Building Regulations 2010 for England in relation to PIR insulation in flat roofing applications and looks at the thermal and strength characteristics of PIR to help designers understand how and where PIR can be used. 

The document also gives guidance on other properties pertinent to the use of PIR in flat roofing such as fire and thermal performance and compressive strength. It covers the use of PIR in warm roof applications, which accounts for the majority of applications and also looks to address terminology that often causes confusion, in particularly the phrases ‘balcony’ and ‘specified attachment’.

Speaking about the guide, our Chief Executive Simon Storer said “This detailed publication brings clarity in respect of how and where PIR insulation can be used following the changes in building regulations with respect to flat roofing. It also addresses questions that have been raised regarding roofing classifications as well as issues around fire performance, compressive strength and thermal performance.”

At a time when the construction industry is faced with the challenges and opportunities of operating in the wake of COVID-19, the PIR insulation industry is well poised to help deliver better performing buildings both now and in the future, as well as playing a part in helping the UK achieve its net-zero climate change ambitions.
