A straightforward guide to help you get to grips with what’s changed and how ROCKWOOL solutions can help you meet and exceed the new requirements
Changes to Approved Document L 2021 came into force in England on 15 June, spelling big changes to thermal regulations for both new and existing buildings.
To help you get to grips with what’s changed and how ROCKWOOL solutions can help you meet and exceed the new requirements, we’ve created a straightforward guide to Approved Document L 2021.
All you need for thermal performance
We’ve analysed the changes and broken them down into easy-to-digest information for Volume 1: dwellings and Volume 2: buildings other than dwellings, giving you a side-by-side comparison versus the 2013 edition. You’ll also find required u-values at-a-glance, whether you’re working on a wall or warm roof, and a link to our u-value calculator to work out the required thermal performance for your individual project.
Insulation specification
Easy and interactive, use our Approved Document L guide to navigate to the applications you need and find suggested substrate constructions to help meet or exceed the new thermal regulations. We’ve also advised how to use ROCKWOOL insulation alongside other commonly specified materials to help achieve the updated demands.
