Gone are the days of the itchy pink stuff. Hempitecture HempWool is an insulation building material that is good for you and our planet. With an R-Value of R-3.7/in, it outperforms our toxic competitors and is made from 92% industrial hemp fiber.

HempWool comes in various depths and widths to meet your needs.

Hempitecture HempWool is 92% hemp fiber and 8% textile polyester. The thermal resistance is identical to the most commonly used batts insulation products. Our insulation does not contain any VOCs since the product is made with no additives and is biobased. The thermal capacity of Hempitecture HempWool is superior to all insulations on the market because of its high density.

HempWool is easy to work with.

Imagine a job site where all the other trades don’t lament about the day the insulation installers come. Messy, itchy, toxic, conventional insulation isn’t a joy for any builder to be around.

HempWool is good for everyone, from the installers, to other tradespeople on the job, to the client, who gets to live in a healthy, well insulated home.
