Airtightness Training for Builders

This one day training covers air-tightness from top to bottom in a day. Starting with a short discussion on what an air barrier is, and how to define it on your project,  the day quickly becomes a hands-on class that details how an air barrier is made, how it fits at a ceiling junction, how it connects to the foundation or slab, how it works around balconies, decks, and overhangs,  and how it connects to plumbing, sprinklers and vents.

Air barriers can be placed at the interior or exterior of a building. It's not uncommon to have a section of the air barrier on the exterior and another section on the interior. Attendees will be able to experiment with ways to connect the outside to the inside and take the best advantage of project and material options. Attendees will work with a wide range of air-sealing materials and get a deep understanding of available materials, and how they perform. 

a mock blower-door test helps participants see the success (or failure) of their airtightness sealing during the class and understand how to remedy any deficiencies that are found. And, it’s fun!

About the Training

This one day class was developed in 2016 to help builders meet the City Of Vancouver requirements of 3.5 ACH50 by the airtightness experts at RDH Building Science and Small Planet Supply. Since then, over 500 builders, architects and inspectors have been trained to plan and build projects with complete air barriers. In addition to regular classes held at the BCIT High Performance Building Lab, we have created a training lab on wheels to bring the one day class to a location near you which we can bring to your BC location on request.

Builder Class Information

Classes are held on selected Saturdays and start promptly at 9:00 AM and end at 5:00 PM. Lunch is provided, so just bring yourself and work clothes you don't mind dirty, as you work on full-scale building section mock-ups. Students will receive a certificate of completion at the end of the class, and will be ready to make air-tight buildings that meet blower door requirements.

Reduced Tuition Through June 30, 2019

The regular $350 seat has also been reduced to $250 for a full day class thanks to funding from Fortis, BC Hydro, BC Housing and the Province of British Columbia. Update: We will continue to offer the $250 fee until June 30, 2019 in anticipation of continued grant funding of the course

Airtightness Training for Building Inspectors

We also offer a training for inspectors at our Small Planet Supply Vancouver location. This course is slightly shorter than the airtightness course but will give inspectors a solid background in stepcode requirements and what to look for when they inspect buildings that are working to meet the new building codes. We schedule trainings in response to consumer demand, so if you’re interested, add your information to the waiting list and we will notify you when we are scheduling our next training.
