High performance blown insulation for new builds

The honest solution to
high performance insulation

Trufill® Insulation is a high-performance insulation system. It differs from traditional New Zealand insulation systems like batts or blankets because it’s based on blown insulation.

The benefit of blown insulation is that you typically get superior installed R-Values. This means better installed performance which is achieved because the product gets around all the pipework and electrical wiring with few or no gaps.


Made from non-combustible Glasswool, Trufill® blown insulation is designed for timber frame walls, floors, skillion roofs and ceilings. The system is designed to provide high performance insulation for new build homes, completely filling the roof and ceiling cavities to create a complete thermal barrier for your home.

Ceiling Insulation

Blown at medium density for skillion and open or low for truss.

Wall Insulation

Blown at high density for typical homes or ultra for higher performance.

Midfloor Insulation

Blown at low to medium density depending on reqirements.

Underfloor Insulation

Blown at low to medium density depending on requirements.

About Trufill Insulation

Blown insulation systems have been used internationally for years but you haven’t often seen these systems in New Zealand. New Zealand insulation standards have typically been quite low compared to the rest of the world and builders haven’t needed to look outside established product solutions. Recent changes to the building code mean we’re going to see new high-performance systems introduced to meet the new requirements. Trufill’s blown insulation system is the perfect insulation solution to meet these new standards.

One of the great things about the Trufill® system is its flexibility. It can be used for insulating ceilings, walls, underfloor, midfloor and acoustic applications. The versatility of the system means it can be used across almost all types of building styles and can be blown at different densities and thicknesses to achieve a wide range of installed R-Values. Depending on the type of build, we can configure the system to suit your application.

Trufill® has a nationwide distribution network and can install your house regardless of where it is in New Zealand. If you’re worried about the pending changes to H1 or you’re looking to build a high-performance home please get in touch with us.

Wall Insulation

I have just put CosyWall into my older wooden house which was always colder inside than outside in the winter. The heat pump had to work extra hard but still had to wrap up in a blanket to keep warm.

I would recommend CosyWall to everyone for a warmer, less draft and quieter better sleep and less worry about power bills that I couldn’t pay. The staff went out of there way to do a excellent job with no stress.
