Havelock Wool batts are made from 100% natural sheep wool and provide a genuinely sustainable, chemical-free insulation option. Wool's unique molecular structure allows it to absorb and release moisture without losing thermal performance — making it exceptionally well-suited to New England's variable humidity climate.
Wool batts achieve R-13 to R-21 depending on thickness. They are naturally fire-resistant (self-extinguishing), have natural pest-deterring lanolin, and do not require chemical fire retardant treatment. Their moisture-regulating properties make them particularly valuable in older Boston-area homes.
