High performance insulation

A high performing thermal envelope is at the core of an energy efficient, sustainable, healthy home with high levels of insulation that help prevent energy loss and reduce the heating and cooling needs of a building. Insulation requirements in New Zealand are minimal compared to international levels and are currently under review, so you will want to upgrade your insulation so your new home performs to the new standards. If you want to meet Passive House requirements or are interested in sustainable building and achieving higher Homestar ratings, you will need much higher levels of insulation than those required by our current New Zealand Building Code.

Enveloped also offer experienced installation in Auckland and Christchurch - check out some of our projects. The team also understands the complexities involved in installing double layer insulation in conjunction with airtightness membranes in Passive House and high performance homes. We take pride in using the correct equipment to ensure a perfect fit and perfect performance of your insulation. ​
