Thermal Heart+ and Solux-E

Elegant Solutions for New Insulation Requirements

On November 2, 2023, a significant milestone was reached in New Zealand’s building industry with the implementation of the H1 clause in the Building Code. This update raised the minimum construction R-value requirements for roofs, walls, floors, windows, and doors, aiming to promote healthier homes with improved energy efficiency.

A key part of achieving these new standards is glazing, which makes up one of the largest surfaces in a home’s building envelope—the protective layer that separates indoors from outdoors.

Warm Frame vs Cold Frame

Our trusted window supplier, Vantage Windows North Shore, offers an elegant solution for homeowners: the Thermal Heart+ system paired with Solux-E low-E glass.

Unlike traditional aluminium ‘cold frames’, which conduct cold (and heat in summer) easily due to high thermal conductivity, Thermal Heart+ incorporates a polyamide thermal break. This barrier stops heat transfer through the frame, creating a consistently warm frame that contributes to a more energy-efficient home.

Solux-E Glass: Designed for New Zealand Homes

In addition to the Thermal Heart+ frame, Solux-E glass improves energy efficiency by:

  • Retaining heat in winter

  • Blocking excessive heat in summer

Many low-E glass options on the market were developed for European climates and don’t fully prevent overheating. Solux-E, designed locally by AGP, is specifically tailored for New Zealand conditions. It also includes Argon gas, reducing heat exchange and further enhancing insulation.

Why This Matters for Homeowners

Together, Thermal Heart+ and Solux-E provide a simple, elegant way to meet the new H1 healthy home standards. These solutions:

  • Improve your home’s energy efficiency

  • Contribute to a healthier, more comfortable indoor environment

  • Minimise heat loss and gain through windows
