In this episode of the In The House Podcast, a construction podcast hosted by Lonnie and

Michael, they sit down with Paul Beavers, owner and senior consultant at Pinpoint Building

Envelope Consultants, to ask a question most builders never do: is the minimum code standard

for airtightness actually good enough?

Paul has spent 36 years testing buildings, moving from a roofing business he started in college

into decades running his own consulting firm — work that today spans everything from high-end

homes to Army Corps of Engineers facilities. He breaks down why the residential industry's go-

to test, ACH50, can hide more leakage than it reveals, and walks through the building

performance test the Army Corps actually uses: pressurizing a building to 75 pascals, tracking air

movement with infrared cameras, and holding it to a leakage rate most homes never come close

to.

They also get into window and door testing — and why, nine times out of ten, the defect Paul

finds isn't bad installation, it's the window unit itself.

Then Paul gets personal, sharing what happened when he tested his own home's envelope during

the February 2021 Texas freeze: no heater, just fireplaces, and a house that only dropped three

degrees overnight. He explains the wall assembly behind that result, the ongoing debate around

closed-cell versus open-cell spray foam.

Whether you're a builder, architect, or homeowner trying to understand what's really protecting

your walls, this episode will change how you think about the word “tight.”
