Havelock Wool
Sheep's Wool Insulation
Description
Havelock Wool transforms raw sheep’s wool into a high-performance thermal, acoustic, and air-quality material. Soft in hand, but highly technical in behavior, it regulates temperature, manages moisture, and quietly improves the feel of a space.
Uses
Walls
Stud cavities in residential and light commercial construction. Ideal for breathable assemblies.
Roofs + Ceilings
Attics, rafters, and cathedral ceilings where thermal stability and moisture buffering are critical.
Floors
Between joists for thermal and acoustic separation.
Acoustic Applications
Studios, offices, and shared environments where sound absorption matters.
Retrofit + Restoration
A natural fit for projects prioritizing low-toxicity and vapor-open assemblies.
Specialty
Van builds, ADUs, and small structures where indoor air quality is heightened.
Why it works?
Moisture buffering
Wool fibers absorb and release moisture without losing insulating performance, helping regulate humidity and reduce condensation risk
Thermal performance
Captures air within its crimped fibers, delivering stable R-values across changing conditions
Air quality
Naturally filters indoor air and can bind harmful compounds such as VOCs
Acoustic control
Dense, fibrous structure absorbs sound and reduces transmission between spaces
Fire resistance
Inherently flame-resistant without relying on heavy chemical treatments
About Havelock Wool
Havelock Wool is a U.S.-based insulation company focused on producing high-performance building materials from natural sheep’s wool. Their insulation is made from premium New Zealand wool, processed and manufactured in the United States, combining traditional fiber with modern building science.
At its core, the company is built around a simple idea:
insulation should improve both building performance and human health.
Sustainability Details
Rapidly renewable
Made from sheep’s wool, a continuously renewable natural fiber
Biodegradable + compostable
Returns to the earth at end of life without persistent waste
Low embodied impact
Requires significantly less energy to produce than synthetic insulation materials
Non-toxic
Free from harmful off-gassing and safe to handle without protective equipment
Long lifecycle
Maintains performance for decades without settling or degradation
