Airtightness Champions Training (ACT) - 8 part series

The Green Register in partnership with Aldas

Booking currently suspended awaiting new dates - TBC


Upcoming revisions to Building Regulations require increased levels of insulation in walls, floors and roofs (the external envelope) to minimise heat loss, but the elephant in the room is – and has been for some time - achieving good levels of AIRTIGHTNESS to prevent expensive warm air from being lost through unwanted leakage through the envelope.

A simple study by the Institute of Building Physics in Stuttgart illustrates how much heat is lost through very small gaps-see illustration below:

This training uses Paul Jennings’ ’12 Steps to Airtightness’ to train you how to achieve effective airtightness delivery through an 8-session on-line Airtightness Champions (ATC) Programme, commencing on June 14th 2022.

- 6 x ‘live online’ 2-hour sessions
- 2 x 3-hour sessions
- Green Register Certificate in Airtightness
- supported by ATTMA (Air Tightness Testing & Measurement Association)

This course is designed to give attendees the skills and background knowledge to design and oversee the challenges of successful airtightness delivery on site, whether they work for large contractors, for smaller local builders, architects or self-builders working on their own homes.
