Envirowool

Wool is the Way

Envirowool is proudly supplied and installed exclusively in the Southland, Western Southland, Northern Southland, Eastern Southland, and Central Otago areas. Our team is committed to delivering high-quality insulation solutions tailored to the specific needs of homes and buildings in these regions.

For centuries, wool has been known for its superior warmth, yet synthetic insulation still dominates the market. That’s changing, and Envirowool® is at the forefront with one of the purest wool insulation products available.

Why Wool?

Wool is nature's own insulation, offering natural temperature regulation, moisture absorption, and breathability. Unlike synthetic alternatives, wool is renewable, biodegradable, flame-retardant, and non-allergenic. It actively absorbs and releases moisture, creating a healthier, drier, and more comfortable indoor environment.

Wool is also naturally fire-resistant, with a high ignition threshold and self-extinguishing properties, making it a safer choice for insulation.

Why Insulate?

Insulation is essential for maintaining a comfortable and energy-efficient home. Without proper insulation, up to 40% of heat loss occurs through the ceiling. Envirowool® helps prevent this, leading to a warmer home, lower energy costs, and a reduced carbon footprint.

A well-insulated home is also healthier, reducing dampness and mould, which can cause respiratory issues. Our product is ideal for asthma and allergy sufferers, thanks to its pure, non-allergenic New Zealand wool composition.

We provide insulation removal, top-ups, and full installations. Our aeration technology ensures optimal loft and coverage, even reaching small spaces through existing timber.

Why Envirowool?

Envirowool® is made from 100% pure, sustainably sourced New Zealand wool. We work closely with Christchurch-based suppliers to handpick the best wool for superior insulation performance. Our insulation provides high loft, density, and excellent thermal properties, ensuring long-term effectiveness.

As a subsidiary of BJ Carter Builders & Insulators, we bring over 50 years of experience in the building industry. Our team consists of qualified tradespeople who understand the structural dynamics of homes, ensuring expert installation.

Even the best insulation won’t perform well unless it’s installed correctly. That’s why we thoroughly assess each project and ensure insulation is applied safely and effectively. We also remove old insulation with powerful extraction systems, replacing it with fresh, high-quality Envirowool®.
