119 | A Natural Alternative to Fiberglass Insulation

Today we're talking about something toxic hiding right under your nose… inside the walls in your home, in fact.

The nasty pink fiberglass insulation contains formaldehyde and binding agents that release harmful VOCs into your home for years. Those tiny glass fibers can become airborne, causing respiratory issues, skin rashes, and eye irritation. Studies link long-term exposure to fiberglass to serious health conditions.

But what if there's a better alternative that's been around for thousands of years? Something that won’t harm you, your family, or the planet. A material that naturally regulates moisture, reduces noise, resists fire, and actually helps clean your indoor air.

We explore why wool insulation is superior for homes and commercial buildings. Joining us is Andrew W. Legge, founder of Havelock Wool, who's passionate about New Zealand wool and creating positive change in the building industry.
