Wall Assemblies Explained
A wall is never just a wall.
It is a system with a job.
Peel back the layers hiding inside every wall and understand what each one does — knowledge that turns fuzzy drawings into details you can defend on site.
Wall sections will stop being guesswork for you.
- See inside walls — know every layer and exactly why it is there
- Draw with confidence — detail sections that contractors respect instead of question
- Prevent failures early — catch the mistakes that cause damp, cracks and callbacks
- Speak site language — discuss build-ups and sequencing with builders as a genuine equal
- Choose systems wisely — match the right construction to climate, budget and use
- Defend your details — answer tough technical questions without breaking a sweat

Wall sections were the part of my drawings I copied from precedent without understanding. This course built up assemblies layer by layer, explaining what each membrane and cavity actually does. I now draw wall sections from first principles and can defend every line in them.

Answered simply.
I can draw a wall but can't explain it — is that who this is for?
Exactly. You'll go from copying details to knowing what every layer does, which is the difference site teams and seniors notice immediately.
Does this cover different climates and construction cultures?
Yes — the layer logic is taught as principles first, so you can adapt assemblies to your local materials and weather with confidence.
Do I need any prior experience?
No. Every course starts from where you are and builds up step by step, in plain language.
Is this software training?
No — software changes yearly. The thinking you learn here lasts a career.
How does it work?
Short video lessons with a small practice task after each. Any device, your pace.
