Havelock wool insulation is a high-performance, 100% natural insulation solution made entirely from renewable sheep’s wool. Ideal for both blown-in attic applications and traditional batts, it provides an exceptional thermal resistance of R-3.6 to R-4.2 per inch. Unlike synthetic materials, wool is naturally dynamic—it actively manages moisture by absorbing and releasing water vapor without losing its insulating power or favoring mold growth. It also naturally filters harmful indoor air pollutants like formaldehyde, dampens sound, and is inherently fire-resistant without toxic chemical additives, making it the ultimate clean, eco-conscious choice for a healthier building.

Key Benefits

• Active Moisture Management: Naturally absorbs and releases up to 35% of its weight in moisture without feeling wet or losing R-value, preventing mold growth.

• Air-Purifying & Non-Toxic: Binds and neutralizes harmful VOCs (like formaldehyde) to actively improve indoor air quality.

• Natural Fire & Pest Resistance: Inherently flame-resistant and treated with natural borates to repel insects and rodents without harsh synthetic chemicals.

• Superior Acoustic & Thermal Comfort: Dense natural fibers absorb sound for a quieter home while delivering high-efficiency thermal performance (R-3.6–R-4.2 per inch).
