Havelock Wool

What it does

Havelock Wool is a premium-grade sheep wool batt insulation engineered for residential and light-commercial framed-wall construction. Made from 100% New Zealand sheep wool with no added chemicals, it delivers thermal performance, sound dampening, and humidity buffering that improves indoor air quality over the life of the building.

Pre-cut for both 16″ and 24″ on-center wood-stud framing in multiple R-values, Havelock Wool friction-fits cleanly with no itch, dust, or off-gassing — and the natural keratin in the wool actively absorbs and neutralizes airborne VOCs (formaldehyde, NOx, SO₂).

When to use it

• Exterior wall cavities in wood-framed construction
• Above-grade and basement walls
• Attics, cathedral ceilings, and exposed floors
• New construction and retrofits
• Projects where IAQ, fire safety, and natural materials matter

Key benefits

• Naturally fire-resistant — wool self-extinguishes; no added flame retardants
• Active VOC absorption — wool keratin binds formaldehyde and other pollutants
• Humidity-buffering — absorbs/releases moisture without losing R-value
• Sound absorption competitive with stone wool at equivalent thickness
• Non-toxic and biodegradable; safe to handle without PPE
• 100% sheep wool — renewable, recyclable, carbon-storing

Format

Pre-cut sheep wool batts in 16″ O.C. (15.5″ wide × 46.5″ long) and 24″ O.C. (23.5″ wide × 46.5″ long), available in R-14 (3.5″ thick) and R-22 (5.5″ thick).
