Natural High-Performance Wool Insulation
Why natural wool insulation is superior to every other insulation product currently on the market:
Homes are increasingly sick. Conversely, there are few places like the New Zealand countryside where sheep dominate the landscape. The fiber developed over 1000s of years in nature’s R&D department provides an unparalleled solution to an increasing challenge in the built environment.

WHAT YOUR ARCHITECT, GENERAL CONTRACTOR AND INSULATION INSTALLER SHOULD BE TELLING YOU ABOUT WOOL INSULATION:
- Filters air and improves indoor air quality – harmful chemicals are in your walls. The amino acids in wool irreversibly bond with formaldehyde, NOₓ and SO2 on a molecular level.
- Moisture and climate control – moisture and mold happens in your walls. Wool absorbs and adsorbs it against 65% relative humidity.
- Suppresses mold and mildew – natural keratin prevents against the spread of mold and mildew.
- Absorbs sound – wool exceeds other forms of insulation as an acoustic buffer.
- Thermal conductivity – wool batts are industry standard at 3.6 per inch; loose-fill outperforms at 4.3 per inch.
- Resists fire – wool will not support a flame below 1100F; conforms to Class A of the ASTM E84 test.
- All natural – wool insulation is entirely renewable and sustainable.
- Long lasting – inherent characteristics allow stated R-values to exceed other forms of insulation.
- No off-gassing – natural characteristics make Havelock's insulation devoid of harmful chemicals.
- Installs easily – blow-in and batts are installed like other mediums but with no protection required.
Havelock Loose Fill Wool Insulation
Loose fill insulation is increasingly preferred amongst industry leaders in the built environment. Havelock Wool loose fill insulation is widely used in residential and commercial construction applications that require superior thermal, moisture and acoustic insulation.
Havelock produces their loose fill following a proprietary and repeatable manufacturing process. This yields knops, or balls, that enhance their wool’s ability to trap increasing amounts of air. This process accelerates wool’s inherent characteristics and allows them to exceed the R-values of all other insulation mediums except the most toxic: spray foam.
WHAT IS LOOSE FILL INSULATION?
Loose fill or “blown-in” insulation is a more recent entrant into the insulation market. Installation begins with a membrane placed over open stud bays, or a hole poked in an existing wall, and insulation is blown behind.
Traditional batt insulation “slumps” overtime. This creates air gaps and a drop in insulation R-value. Loose fill insulation prevents this by filling your wall cavity more completely.
Havelock Wool Batt Insulation
Havelock has applied their insulating technology to traditional batt insulation. Historically batts were made with toxic bonding agents necessary to create a low-cost insulating product with some ability to maintain shape. Their batts are made with 100% wool, no synthetic mix, and are bonded with a needle punch, not chemicals.
Unlike other forms of insulation, Havelock's batts are easy to handle. They 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 them the label as the ultimate in DIY for home insulation.
WHAT IS BATT INSULATION?
Batt insulation takes a rectangular shape and it is designed to slide into the cavity of your interior walls. 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.
