Meet H1 with New R7 Single Layer Ceiling Insulation from Knauf

Knauf Insulation is transforming the way ceiling insulation is installed with a new high-performing R7.0 single layer ceiling batt. The R7.0 ceiling solution is extra thick, allowing it to be installed in a single layer with no notching, instead of the time-consuming double layering method, without compromising the H1 New Zealand building code requirements that are now mandatory for newly built New Zealand homes.

Knauf Insulation’s single layer ceiling solution, available in both their Earthwool glasswool and ecoinsulation ranges, features advanced DriTherm Technology, which is used in the manufacturing process, to provide a high level of water resistance. Both ranges are made with up to 80% recycled glass, are non-combustible, and feature Knauf Insulation’s unique bio-based binder — ECOSE Technology, which uses no added formaldehyde. Furthermore, the glasswool ranges feature TwinTech Technology, a dual forming technique that produces a smooth finish on both sides which further enhances the installation process.

With an incredible range of benefits, Knauf Insulation’s R7.0 single layer ceiling range is designed “over-wide” to deliver a deliberate knit-joint fit with adjacent batts. This provides a complete layer of unbridged insulation to meet the new H1 R-value requirements and eliminates the need for notching, while reducing the complexity of installation. Additionally, Knauf Insulation’s Earthwool glasswool and ecoinsulation products are BRANZ approved and backed by independent certification to ensure installation remains compliant with New Zealand’s H1 requirements.

The single layer glasswool insulation solution from Knauf insulation has less embodied carbon, compared to installing two layers of ceiling insulation, achieves a high R-value of 7.0 in one layer, and requires no need for cross hatching therefore saving time and money on your next project.

Keep an eye out for Knauf Insulation’s new Earthwool glasswool range at Bunnings and ecoinsulation glasswool at Carters.
