Blown-In Havelock Sheep Wool Insulation Is A Breeze

Installing blown-in (loose-fill) wool insulation at a professional level just got a whole lot easier. Havelock Wool is changing the game by offering blower rentals directly from Havelock. This is important because the blower they recommend most highly is not the standard model used by cellulose installers. The best part? The rental is free for the first 10 days (a refundable deposit is required.)

Why Blown-In Wool?

Sheep wool is a great choice for occupant health and indoor air quality, without the chemicals and itch of fiberglass insulation. Loose-filling, blown-in wool fits all types of cavities and can easily be blown around electrical, plumbing, and into tight corners. This makes attic installation much easier, as the blower enables quick and even coverage. At a R-value of 4.3 per inch, loose-fill Havelock Wool has a remarkable high insulation value. This gives a better sound attenuation as well: loose-fill has a Noise Reduction Coefficients (NRC) Rating of 0.95 - the highest possible rating being a 1.0.

The Process

Installing blown-in insulation is a relatively quick and clean process (though we still recommend wearing a good dust mask.) Like cellulose, blowing loose-fill Havelock requires stapling up netting against 2x framing to enclose a bay, and then inserting the blower tube through a hole to blow into the bay. It requires a bit of prep work, but we’ve found that the speed of installation more than offsets the amount of preparation needed.

Watch Josh and Cyrus walk you through the simple process from start-to-finish. The video outlines the tools needed, hopper setup, and directions for blowing in vertical walls and attics.

Given the availability of the recommended blower machine, the benefits of Havelock Wool for insulation value, air quality improvements, moisture management, and sound reduction are hard to compare.

Case Study: Harlem Passive House Retrofit From CO Adaptive

In a great example featured on the Havelock Wool blog, we see CO Adaptive using the combination of loose-filled, blown-in Havelock Wool insulation with Pro Clima airtightness and vapor control provided by INTELLO PLUS. Following the Smart Enclosure guidance for masonry retrofit projects, this brownstone retrofit in Harlem will achieve Passive House certification while retaining the finished look from 1910, when it was first constructed.

“The owners want a renovation that preserves the history of the home but that also uses design and materials to improve the layout, functionality, and health impacts. Using the Passive House (PH) standard helps guide decisions along the way. “
