Thermal Bridging and Insulation
Heat escapes through shortcuts.
Find them before they cost you.
Track the sneaky paths heat takes through structures and learn to design envelopes that stay warm, efficient and condensation-free without guesswork.
Cold spots will vanish from the envelopes you detail.
- Hunt the cold spots — find where heat leaks through balconies, lintels and junctions
- Understand insulation properly — know what different materials actually do and where they belong
- Defeat hidden condensation — prevent the trapped moisture that rots buildings from inside
- Detail warm junctions — design the tricky corners that make or break performance
- Meet efficiency targets — deliver real comfort and easy compliance without inflating the budget
- Argue with evidence — back your envelope decisions with reasoning consultants respect

A few hours from now, you could already see differently.
Thermal bridges were red blobs in someone else's software as far as I was concerned. The course showed me where bridges form, why they matter for condensation and energy, and how detailing kills them. I now catch cold bridges at sketch design stage, before they cost anyone money.
Simple by design.

Answered simply.
Is thermal bridging really worth a whole course?
Bridges quietly wreck energy targets and grow mould on finished walls. Learning to spot and fix them is one of the highest-leverage detailing skills there is.
Do I need physics to follow this?
Just the intuition the course gives you — heat flow is taught visually, through details, not equations.
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.
What does membership include?
