Preferred by New Zealand’s leading residential building companies, ECO Insulation is renowned for its high quality, affordability, and EnergySmart’s exceptional service standards.

The new H1 regulations in New Zealand establish minimum nationwide energy efficiency standards for residential and commercial buildings. EnergySmart uses the Calculation method to identify cost-effective ways to achieve compliance, often finding savings in slab design and glazing that outweigh insulation costs. The ECO Insulation range is specifically designed to meet these requirements. EnergySmart offers a free H1 design service, including plan take-offs, cost optimization for slabs, glazing, wall depths, and insulation, as well as H1 compliance certificates recognized by consenting authorities.

Even post-consent, EnergySmart can assist with design optimization and consent variations. For those preferring to manage designs independently, EnergySmart provides a free optimization tool, with a full H1 calculator forthcoming. EnergySmart was actively involved in recent the H1 consultation, to ensures its ECO Insulation and H1 advice remains innovative, cost-effective, and aligned with compliance needs.

ECO Insulation products are renowned to be super-soft, low dust and low itch and encompass a full range of insulation solutions for 45mm, 90mm and 140mm walls, and skillion and truss roofs. Our R7.0 ceiling batt is designed to cover the bottom chord of the roof truss, and is an extremely cost effective and high-performance option, unrivalled outside of the Knauf Insulation family of products. Our skillion roof products are designed for the maximum thermal rating possible within the depth of the rafter (190mm, 240mm and 290mm) while maintaining the critical 25mm airflow gap without having to add counter battens or specialised vent strips. Our specialised perimeter insulation for use in truss roof construction maintains the required 25mm airflow gap while meeting the thermal requirements of the building code. Because we are an installing company, we understand the challenges of framing geometry and design the Eco range of products to be compliant and effective.

Our retrofit R3.6 and R4.2 ceiling products offer an excellent, durable and cost-effective solution for existing homes. Our versatile range of products provides excellent thermal and acoustic performance, making homes and businesses more energy-efficient and comfortable all year-round. Whether for a large-scale commercial project or a small residential retrofit, ECO Insulation offers tailored solutions for all needs.

Insulation is essential for creating a healthy, comfortable home by regulating indoor temperatures and preventing dampness and mold. Proper insulation improves energy efficiency, reduces heating costs, and promotes better indoor air quality.

Under New Zealand’s Healthy Homes Standards, landlords are now required to insulate rental properties to meet specific regulations, ensuring tenants live in homes that support their well-being. Additionally, the Warmer Kiwi Homes program offers subsidies for eligible homeowners, making high-quality insulation more affordable for many families and contributing to the country’s overall health and sustainability goals.
