NEW Wool Window & Door Insulation
Ordering details
Each Window & Door Insulation Kit comes with 2 Lbs of loose fill wool.
An ideal installation density is about 1.13 Lb per cubic foot, so each kit provides enough insulation to fill the gaps around 2-4 windows or doors depending on the size.
Add up the total volume of your gaps in cubic feet and divide by 1.13 to get a more accurate estimate of the quantity of wool required for your project.
To insulate around a lot of windows and doors, consider a larger quantity of Havelock Wool Loose Fill Insulation.
Shipping
- Small orders ship in boxes via courier.
- Pallet orders ship LTL on a freight truck. Freight shipments are typically delivered to the curb of the street or driveway, and they include lift-gate service. The freight company will contact you to make an appointment for final delivery.
Description
Wool Window & Door Insulation provides a natural solution for insulating around windows and doors, to seal gaps where temperature transfer commonly occurs, and to improve overall energy efficiency.
The wool's natural structure creates millions of microscopic air pockets that effectively slow heat movement in both directions. During winter months, this insulation prevents warm air from escaping, while in summer it blocks external heat from entering the building.
Unlike synthetic insulation materials, wool is renewable, biodegradable, and contains no harmful chemicals or VOCs. The material also has natural moisture-wicking properties that help manage condensation issues often found around windows and doors.
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.
Absorbs sound
Wool exceeds other forms of insulation as an acoustic buffer and is commonly used to naturally enhance the acoustic properties of a building.
Thermal conductivity
Wool batts are industry standard at R-3.6 per inch; loose-fill outperforms at R-4.3 per inch.
Resists fire
Wool will not support a flame below 1100ºF (593ºC). Havelock wool conforms to Class A of the ASTM E84 test.
All natural
Wool insulation is entirely renewable, biodegradable, and sustainable. It takes approximately 10% of the embodied energy it takes to manufacture fibreglass insulation.
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 types of fibrous insulation but with no special protection required.
