Sheep's Wool Insulation Batts
Havelock Wool has discontinued their classic 100% wool batts. They have released a new product called Havelock Wool Pro batting, which includes a 5% Poly binder to make the batts firmer and easier to manage. We do not stock Havelock Pro batts, but we can do special orders in pallet quantities (12 bags per pallet). Please contact us.
We still stock 100% wool designed for vans... it is the same product as the classic batts. Our loose-fill product is also still 100% wool.
Please also see our LOOSE-FILL Insulation!
100% Natural Sheep's Wool Batt Insulation is a high-performance and eco-friendly alternative to conventional insulation.
- Harmful chemicals are in your walls; wool filters the air and improves indoor air quality. The amino acids in wool irreversibly bond with formaldehyde, NOₓ and SO2 on a molecular level.
- Moisture and climate control – moisture and mold happen in your walls. Wool absorbs and adsorbs it against 65% relative humidity.
- Suppresses mold and mildew – natural keratin prevents 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 our insulation devoid of harmful chemicals.
- Installs easily – blow-in and batts are installed like other mediums but with no protection required.
