Havelock Wool Batt Insulation
We have applied our insulating technology to traditional batts. Historically batts were made with toxic bonding agents necessary to create a low-cost insulating product with some ability to maintain shape. Our batts are made with 100% wool, no synthetic mix, and are bonded with a needle punch, not chemicals.
Unlike other forms of insulation our batts do not require protective clothing or safety equipment like respirators, gloves or heavy clothing to install: they are safe to the touch.
These characteristics have earned us the label as the ultimate in DIY insulation.
What is Batt Insulation?
Batt insulation takes a rectangular shape designed to slide into the cavity. It is the cheapest and most common type available in the market. The efficacy of batt insulation is increasingly scrutinized by industry practitioners though the ease of install will allow for its dominant usage to persist.
Benefits of Wool Batt Insulation
Our product is all-natural, renewable and sustainable in it’s production, while being compostable at the end of an extended useful life. Wool is inherently self-extinguishing and manages moisture against 65% relative humidity. Our batts perform similarly to other forms of insulation with an R-value of 3.6 per inch. Unlike others, no protective clothing is required for installation and one can argue the process is even a bit of fun.
The Ultimate in DIY Insulation
Easy to Install – Not Rigid
Batts are typically cut at 48” and may need to be stretched slightly upon removal from packaging. Unfaced batts are applied with friction. A staple may be added at the installers discretion. Wire or lightning rods may be used in a ceiling joist or with metal framing.
Composition & Materials
Havelock Wool batts have no formaldehyde or chemical bonding agent of any sort.
Our batts are comprised of 100% wool. Unlike other options, there is no synthetic mix in our products which means there is no glue or bonding agent. This greatly reduces the net embodied energy in our production process as no high heat is required. By comparison, mineral wool batts are bonded with extreme heat and the binder is formaldehyde.
Our batts are produced employing a mechanically driven needle punch. As a result, they are malleable, not rigid or difficult to manipulate. Some care should be taken in handling with an emphasis on the needled side, which should face out from the wall cavity.

*The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption.
