ROCKWOOL Releases Guide to Approved Document L

Following Approved Document L (England) 2021 coming into force on 15 June 2022, ROCKWOOL has created an easy-to-digest guide to the new building regulations to support specifiers and installers in meeting and exceeding the requirements.

With Approved Document L (ADL) spelling significant changes to thermal regulations for both new and existing buildings, the ROCKWOOL Guide to Approved Document L 2021 unpacks the updates to Volume 1: dwellings and Volume 2: buildings other than dwellings, plus gives users U-value requirements with a handy side-by-side comparison against the 2013 edition.

The Guide also suggests possible substrate constructions using ROCKWOOL stone wool insulation and to support users with real-world specifications, explores how to use ROCKWOOL products alongside other commonly specified materials to help realise the updated demands.

“The changes to ADL are critical in the UK’s journey to achieving net zero carbon emissions by 2050, yet we also recognise that many in the construction industry are busier than ever,” said James Francis, Product Manager, ROCKWOOL UK.

“Our guide to ADL summarises the need-to-know information and supports with practical tools and construction approaches that specifiers can use as a basis for their project.”

Available at the link below, the ROCKWOOL Guide to Approved Document L is an interactive resource, helping users access the information they need with ease.
