MBC Timber Frame Ltd.

Ever wonder what an airtightness test on a new build looks like? Here’s a sneak peek into one of our latest airtightness tests in Cheltenham.

At MBC, our High-Performance System is guaranteed to achieve an air change rate of 3.0 AC/HR, while our Passive House System achieves 0.6 AC/HR. These levels of airtightness make every MBC project compatible with MVHR systems, should the client choose to install one, helping to deliver exceptional energy efficiency, indoor comfort, and overall building performance.

This project, which uses our High-Performance timber frame package, achieved a fantastic result of 1.15 AC/HR - significantly exceeding the guaranteed rate of 3.0 AC/HR.
