Havelock Wool PRO R22 Batt insulation - 16" OC

The batts fit really well for my 1941 built SF home. The floor above my garage is noticably warmer when walking barefoot than pre-batt install. It has muffled some of the sound from above so it doesn't sound like you're in the same room when in the garage.

The installation process itself is straightforward and the batts are well made. I tried using a drywall saw and it was really difficult to cut through the thick batts. I ended up buying heavy-duty shears based on their online video and that has worked much better! It's still hard to cut through given how thick the batts are but I take that as a good sign of the wool being packed tight as it should be.

I've also been working w/the wool w/out any itching/reactions which has been really nice vs other insulation materials. I'm not worried about my kids being around the batts either. This product is worth it as a DIYer and am extremely happy w/the cost for this high quality product.

Recently bought R20 16OC batts from Havelock wool. The product arrived on time and it good condition. The install was easy and much better than working with fiberglass. But the most thing I was impressed with was customer service. Peter and Josh were great to work with and very helpful with making sure install went smoothly, and product arrived correctly. 5 Star for sure! Beautiful product

After seeing this product on line we decided to purchase for our new home. We compared to conventional insulation and felt like we were making a responsible choice. We loved how easy it was to handle and after building the cutting jig the install went smoothly. One drawback is that we didn’t know about the R-value in the attic. We failed to calculate the depth needed to achieve what we wanted in the attic. Because we used our budget we couldn’t afford to order more so we paid to have insulation blown in. Which was lesser in comparison. If I had to do it again I would gladly buy Havelock, I would be sure to budget it.

We had to use electric sheep shears to cut the insulation easily without compressing it. The insulation knife just didn't cut it. Even though it has a tiny amount of polyester I truly enjoy the quality of the insulation. It is warm and fuzzy and definitely has sound abatement. I hope that it will transfer moisture seamlessly without causing rot as we chose not to use any form of plastic vapor barrier in our 200+ year old house whose hand hewn beams are still intact without previous vapor barrier. I tried burning the wool and it just went out! Overall an excellent product as we were able to borrow the shears and then it installed beautifully without toxicity.

In our older house in the cool and rainy Pacific NW there was no insulation in the wall shared with our single car attached garage. I wasn't looking forward to working with fiberglass, mineral wool or foam as an elderly do-it-yourselfer on an unfamiliar project. The wool batts were a pleasure to work with despite the many framing members that weren't on 16 or 24 inch centers. I would make the same choice again if I needed to despite the cost of shipping
