Changes to H1 2022

As you'll all be aware the shift to the 5th edition of the H1 documents becomes mandatory from November 1st. In this video Mark Fairbairn, National Sales and Marketing Manager, spoke with Sarah Sandland, who had run the team incorporating the H1 changes at Masterspec.

Much has been made of the changes to insulation requirements, however the task to incorporate the changes into the Masterspec specification system has required changes to over 250 work sections across all the entire CBI (Co-ordinated Building Information) Group 1 classes. Anything with an insulation performance requirement is included in the new H1 documents. It's a simple overview but contains valuable information on how to proceed.


Check out the chart below containing a summary of what's changing when.
