Havelock Wool is a natural sheep wool insulation that actively regulates moisture by absorbing and releasing vapor without losing its insulating properties. It is chemical-free, non-irritating to install, and provides a genuinely sustainable insulation option for environmentally conscious homeowners.
Sheep wool achieves approximately R-3.5 per inch and has a unique ability to absorb up to 30% of its weight in moisture without losing thermal performance — making it particularly well-suited for older New England homes where moisture management is critical.
Absorbs and releases moisture without degrading R-value — self-regulating in variable humidity climates
No VOCs, no formaldehyde, no fire retardant chemicals — safe for occupants with sensitivities
Unlike fiberglass, sheep wool is safe to handle without PPE — comfortable for homeowners present during installation
