Indoor Chemistry Test: Formaldehyde and VOCs during Construction

Modern homes are built more airtight than ever, and the engineered wood products that make such efficient use of our planet's materials also lean much more heavily on advances in adhesives, curing agents, moisture repellants, etc. Other building materials nowadays incorporate anti-microbial chemicals, anti-fungal and anti-termite compounds, and who knows what else (manufacturers DO NOT have to tell us what's in there, yet). The beyond-passive-house-airtight house we're building in Atlanta is an extreme example of all of this, and we'll happily be the guinea pigs to uncover the evolution of indoor chemistry from rough construction through ventilation activation, and move-in. Hayward Score has introduced us to a serious chemistry lab, Prism Analytical Technologies (http://pati-air.com) where we'll be sending the samples we take in this video. See what we're testing for, why, and how it's done.

Corbett gets serious details about indoor chemistry from Dr. Alice Delia, Laboratory Director at Prism Analytical Technologies (http://pati-air.com) about the test results from 6 samples of formaldehyde and Volatile Organic Compounds taken at the new build and the TinyLab.

FLOOD in an Airtight Tiny House

Watch Corbett and Grace deal with a 25 gallon leak from their freshwater bag in the #TinyLab. Thanks to Jim Clark for all the help mopping and drying in Phoenix that day!
