Gutex has been outfitting German buildings with wood fiber insulation for over 85 years, so it’s known and has been well-utilized for generations. But since it first appeared in North America, many have been surprised by the idea that wood can make a safe and natural insulation. A common question is: does it burn? When we met up with long-time insulation specialist, Bill Hulstrunk, he wondered just that. So we decided to film his improvised, on-site flame resistance experiment with GUTEX THERMOFIBER and the new Nature-Tech cardboard cellulose. For more information about GUTEX THERMOFIBER or other wood fiber board insulation options, go to foursevenfive.com (USA) / foursevenfive.ca (Canada).
