Insulation
We are on a mission to make Wellington’s homes warm, dry and energy-efficient with quality ceiling and underfloor insulation.
Planning on getting insulation installed in your home or rental property? Our experienced insulation installers provide professional supply and installation services for homes and rental properties across the Wellington region. Whether you’re building a new property or upgrading an older home, high-quality insulation is essential for maintaining comfortable indoor temperatures, reducing energy costs and improving air quality throughout your home. Our team works with trusted polyester and fibreglass brands, including Mammoth and Pink Batts, to deliver reliable thermal performance that meets both New Zealand Building and Healthy Homes Standards. As a trusted insulation supplier Wellington homeowners rely on, we can help you choose the best insulation system for your property and budget.
We install ceiling or roof insulation and underfloor insulation, ensuring your home is protected from heat loss in winter and excess heat during the summer. Ceiling and roof spaces are among the biggest areas where homes lose warmth; installing insulation can significantly improve energy efficiency in your space, as well as the acoustics!
Thanks to the Government’s Warmer Kiwi Homes programme, and other funding partners, you could be eligible for 50-100% funding for insulation!

Heat escapes through the roof and walls of any building, and out of any gaps, tears or areas missing insulation. Heat loss increases dramatically when the temperature outside is lower than inside, as heat is drawn to cold areas. Good insulation makes homes more energy-efficient, comfortable and healthy. It makes homes easier and cheaper to heat, and adds lasting value to properties.

Insulation can be complicated. There are different materials, features and benefits on the market, and no one-size-fits-all.

Insulation degrades over time, especially insulation that is more than ten years old. Old insulation usually needs a fix-up, top-up or full replacement. Many homes in New Zealand are uninsulated or not insulated properly, for reasons ranging from pre-insulation building construction, low building code standards, poor quality materials or misunderstandings of building science.
“We like the values of the Sustainability Trust, the price was really reasonable, and the feedback we had read from other customers was great. The installers made short work of what turned out to be a pretty tricky job with our ceiling and underfloor insulation. We can’t recommend you highly enough!”
