It wasn’t until our forays in insulation began that we became aware of the relationship between duct insulation and the potential to inhale fiberglass particulate. In other words, we all worked in office buildings, shopped in large commercial buildings for years, and had no idea that extensive ducting feeding us warm and cold air across seasons was lined with fiberglass. We were not rocket scientists then, nor are we now, but you don’t need to understand the randomness of plutonium decay to appreciate that lining HVAC ducting with fiberglass is probably not a great idea. Moreover, it is not only pervasive but often required by code.
To be fair, we don’t question the efficiency advantages of insulating ducting, but fiberglass on the inside of the duct…..that just doesn’t make (common) sense.
Happily, a fix seems like incredibly low-hanging fruit. Our appetites are up and we’re hoping to eat. Also, as this is not our first attempt at disrupting an insulation market so we have added a few strategic partners so as to address necessary concerns for those currently frustrated by the space.
For any enthusiasts out there please note the testing regime is complex, expensive, and not overly precise….read annoying AF, but fear not we will stay the course and do our best to get an alternative on the market as quickly as possible.
I’m wondering what the average price would be to insulate a fairly large house, 4 bedrooms, a century and a half old, which we’re about to start renovating.
It depends on a whole host of factors – total square footage, wall cavities, desired R Value. We sell two main products – batts and loose fill (blown in) and all pricing is on the site. Generally speaking we are at least 2x the cost of fiberglass and in line with closed cell spray foam. Thanks for reaching out!
Yes!!!! Please do!! This is SO important. We are all rooting for you!!
I always think of moths going for wool. Is this a problem?
We apply a slight amount of boric acid which deters all insects, including moths. Thanks!

During my re-roof (including removing/replacing the roof deck with 0.75″ CDX plywood) I removed all the old blown-in fiberglass and cellulose insulation from the entire attic (60+ year old home). I purchased your Havelock bats for the entire attic. The next project is to install a horizontal 90%+ efficient HVAC unit in the attic (currently there is no central air in this house). I am looking for an alternative for the common insulated ‘flex’ ducting because I will not install anything with fiberglass insulation. If you are not able to provide an alternative, I was thinking to use more Havelock bats to attach (somehow) to square/rectangular metal ducting. Any opinions on this potential method/idea?
