New Build Insulation

High-performance insulationfor your new Canterbury home.

Building new in Canterbury means meeting some of the highest insulation standards in New Zealand. Climate Zone 3 requirements under the updated H1/AS1 code are significantly tougher than they were, roof and ceiling insulation now needs to reach R 6.6, up from R 3.3. We work with builders across the region to deliver TruFill insulation that meets and exceeds these requirements.

Why Loft

No gaps.
No compromises.

Loft is a high-performance blown insulation system purpose-built for new construction. Unlike traditional batts that are cut and friction-fitted between framing, often leaving gaps around wiring, plumbing, and awkward junctions, Loft is blown into place and fills every void completely. That means no gaps, no compression around services, and a consistent R-value across the entire surface. In practice, a blown system outperforms batts of the same rated R-value because the real-world installation is more thorough. For Canterbury's cold winters, that difference matters.

What we insulate

One package.
The whole home.

We provide a complete insulation package for new builds: ceiling insulation to meet the new R 6.6 requirement, wall insulation to R 2.6 or above, underfloor insulation for timber-framed floors to R 2.5, and acoustic insulation between bedrooms, bathrooms, and living areas. Having a single insulation provider for the entire build simplifies scheduling, reduces coordination headaches for your builder, and ensures consistent quality throughout. We also handle mid-floor insulation for two-storey builds where thermal and acoustic separation between levels is important.

What you get
  • Ceiling insulation to meet the new R 6.6 requirement
  • Wall insulation to R 2.6 or above
  • Underfloor insulation for timber-framed floors to R 2.5
  • Acoustic insulation between bedrooms, bathrooms, and living areas
  • Mid-floor insulation for two-storey thermal and acoustic separation
  • Single trusted provider for the entire build
Working with your builder

On site at the
right stage.

We've been insulating Canterbury homes for over 20 years, and we understand how build schedules work.

01

Specification

We work with you or your builder to specify R-values and product selection that meet H1/AS1 Climate Zone 3 requirements, with documentation ready for consent.

02

Schedule with builder

We coordinate directly with your builder or project manager so we install at the right stage, after services are roughed in but before the linings go on.

03

Loft install

Our team blows Loft into ceilings, walls, and floors, filling every void around wiring and plumbing for a consistent R-value across the surface.

04

Sign-off

We provide product specifications and R-value calculations for the building consent process, and leave a clean site for the lining crew to follow.

“Canterbury Insulation slot straight into our build programme. One call, the whole house insulated to spec, R-value documentation in our hands for consent. They make the linings stage so much easier.”
