AECB Cumbria Group: Practical Airtightness for Home Owners and Self Builders

September 25, 2019 @ 5:30 pm - 8:00 pm


At its most basic, airtightness aims to eliminate any unintended gaps or cracks in the external fabric of the building. Achieving airtightness in buildings isn’t a dark art, but those that achieve higher levels do tend to be planned, built and executed to a much higher quality level; by joining us and utilising Ecological Building Systems life size training walls we’ll aim to demystify the process, showing top tips and offering invaluable practical training in informal surroundings that will give you the confidence to have a go yourself or supervise on your next new build or retrofit project.

You’ll be trained by Ilias Igoumenidis and Fintan Wallace from Ecological Building Systems, themselves Passivhaus Designers and Tradesman. They will guide you through how to install insulation to achieve optimum results and take you through which airtightness membranes, tapes and seals to use where.

The AECB Cumbria Local Group would like to express their thanks to Ecological Building Systems for hosting this event, together with providing the materials and trainers – it’s going to be a great evening!

Please note that places are normally limited to one per email address/household/business. Please contact the organiser if additional places are needed.

This event is part of the Cumbria Green Build & Sustainable Living Festival which brings ideas, inspiration and skills to green up your home, business or even your community. For further information, please visit:
