Natural Wool Insulation Batting is designed to fit between vertical timber framing, or lay in a blanket form. The batting comes in a variety of forms to suit most building construction.
Sheep's wool insulation batts from Havelock Wool are made with 100% wool, no synthetic mix, and are bonded with a needle punch, not chemicals. At the end of its useful life, our wool is 100% compostable.
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. For example, tests carried out by the Central Testing Facility in Tokyo, Japan found that when formaldehyde was released into a chamber, wool was able to absorb 96% of the formaldehyde within several hours. This capability is unique to natural fibres.
Moisture and climate control
Moisture and mould happens in your walls. Wool can absorb moisture against 65% relative humidity.
Suppresses mold and mildew
Natural keratin prevents against the spread of mould and mildew.
Wool exceeds other forms of insulation as an acoustic buffer and is commonly used to naturally enhance the acoustic properties of a building.
Wool batts are industry standard at R-3.6 per inch; loose-fill outperforms at R-4.3 per inch.
Wool will not support a flame below 1100ºF (593ºC). Havelock wool conforms to Class A of the ASTM E84 test.
Wool insulation is entirely renewable, biodegradable, and sustainable. It takes approximately 10% of the embodied energy it takes to manufacture fibreglass insulation.
Inherent characteristics allow stated R-values to exceed other forms of insulation.
Natural characteristics make our insulation devoid of harmful chemicals.
Blow-in and batts are installed like other types of fibrous insulation but with no special protection required.
