Retrotec

Our latest Flow Lab episode explores what happens when blower door testing goes far beyond residential code compliance.

Sam Myers is joined by Retrotec's Lee Canegaly, along with Michael Allen and Greg Iseral, to discuss enclosure integrity testing in industrial facilities, blast-proof shelters, server rooms, fire suppression systems, and other high-stakes environments where air leakage can have serious consequences.

They share stories from the field, explain why testing always beats guessing, and show how understanding building performance can improve safety, protect critical equipment, and solve problems that aren't always obvious.

Some of the biggest building problems leave no visible clues.

No stains. No swelling. No obvious water damage.

As Brantley May explains, hidden connections between attics, overhangs, wall cavities, and other unconditioned spaces can create serious moisture and air quality issues without showing up on the surface.

That's why building science matters.

If you're only looking for what's visible inside the home, you can miss the root cause entirely. Sometimes the best clues are found by stepping outside and understanding how the whole building is put together.

The most valuable tool you can own isn’t complicated.

It’s a blower door.

Jake Bruton has used one for 15 years, and it’s still the most informative tool in his process. Not just for testing at the end, but for learning, improving, and staying competitive.

Because when you can measure your own work, you stop guessing and start getting better.

And no, it’s not hard to use.
