Havelock Wool - Loose-Fill Wool Insulation - R15 - R60
Experience Superior Insulation with Havelock Wool
Loose fill (also known as blow-in) wool insulation is a natural, eco-friendly material made from sheep's wool, offering excellent thermal performance and sound absorption. It effectively regulates temperature, maintaining warmth in winter and coolness in summer, while also managing moisture to prevent mold growth. Easy to install, this biodegradable insulation contributes to sustainable building practices and enhances energy efficiency in homes and commercial spaces.
Flexible, Full Coverage
Blow-in wool fills gaps, voids, and irregular spaces with ease. It creates seamless insulation around wiring, pipes, and framing for more complete coverage than rigid or batt formats can provide.
"This worked out great for me. I have had minimal exposure to fiberglass insulation and this is SO MUCH better to work with. I highly recommend." - Harold
Better Air with Fewer Toxins
Wool helps trap airborne chemicals like formaldehyde and VOCs while regulating moisture and resisting mold. It supports healthier indoor environments without added adhesives or synthetic binders.
Frequently Asked Questions
What is blow-in insulation?
- Blow-in insulation is a loose-fill material applied using an insulation blower to fill cavities in walls, floors, and attics. It conforms to uneven or hard-to-reach spaces for full coverage.
Where can I use blow-in wool insulation?
- Blow-in wool is ideal for closed cavities, attic floors, hard-to-access areas, and retrofits where traditional batts do not provide a complete fit.
How does blow-in wool compare to cellulose or fiberglass?
- Wool offers better moisture management and air purification than cellulose or fiberglass. It also does not settle over time and does not contain added chemicals.
Does blow-in insulation require special equipment?
- Yes. Installation requires a blower, which can be rented or provided by a professional installer. Havelock offers guidance for DIY users and pros alike.
Is wool blow-in safe for indoor air quality?
- Wool actively filters harmful chemicals and does not off-gas, making it a healthier option for enclosed spaces compared to many synthetic alternatives.
Will blow-in wool settle over time?
- No. Wool fibers naturally interlock and maintain their loft, delivering long-term performance without the sagging or compression seen in some loose-fill products.
