Elevating Energy Efficiency with Knauf’s H1-Compliant Glasswool Insulation Products

In New Zealand's evolving construction landscape¹, meeting H1 energy efficiency regulations is critical for residential and small buildings under 300m². H1 Energy Efficiency represents the most significant advancements in energy efficiency witnessed in the past decade. As architects and designers navigate these requirements, selecting the right insulation product becomes paramount.

Knauf Insulation’s R7.0 glasswool ceiling batt offers an effective solution designed specifically for H1 compliance. With a thermal resistance of R7.0, this single-layer glasswool ceiling batt enhances the energy efficiency of residential projects, ensuring indoor comfort year-round. The innovative design of the R7.0 batt allows for continuous coverage, creating a seamless layer that reduces thermal bridging. This is essential for maximising insulation effectiveness and maintaining compliance with H1 standards.

One of the standout features of Knauf Insulation’s R7.0 glasswool ceiling batt is its efficiency during installation. Unlike traditional double-layer systems, the R7.0 ceiling batts are designed so they do not require notching which will in turn reduce the installation time by up to 40%. This efficiency translates to significant time and cost savings for installers, allowing for quicker project completions without sacrificing quality.

Furthermore, the durability of the R7.0 ceiling batt is enhanced by DriTherm Technology, a silicone treatment, which enhances the product's moisture resistance. This feature is particularly beneficial in New Zealand's varied climate, where moisture management is crucial to maintaining the integrity of building structures.

The R7.0 glasswool ceiling batt has also been certified for use in Kāinga Ora homes, reinforcing its compliance credentials and suitability for government projects. Specifiers can confidently recommend this product, knowing it meets the rigorous standards required in contemporary construction.

As New Zealand continues to prioritise energy efficiency in residential buildings, the need for compliant insulation solutions becomes increasingly vital. Knauf Insulation’s R7.0 glasswool ceiling batt not only meets H1 regulations but also streamlines the installation process, providing a robust and effective solution for specifiers aiming to enhance their projects' comfort and energy performance. For those looking to deliver high-quality, compliant buildings, Knauf Insulation’s R7.0 ceiling batt is a strategic choice that promises both efficiency and reliability.
