Introducing ThermalHeart+®

35-50% of a home’s heat is lost from its windows and doors. Which is why we are introducing ThermalHeart+®. A range of code-meeting, industry-leading, thermally efficient products designed and made right here in New Zealand for exactly how we live.

What is ThermalHeart+®?

It’s new thermal technology for windows and doors that almost doubles the performance of standard aluminium windows and doors1.

This versatile system of thermally efficient frames and unique AGP System® glass creates warmer, drier and healthier homes for both us and the environments we live in. When used with the innovative Centrafix™ installation option, thermal performance is further increased by over 20%2.

Not all windows and doors are created equal and The AGP System® sits right at the heart of our products’ thermal performance.

  • The ATS-Architectural Thermal Spacer®️ reduces the transfer of hot and cold temperatures
  • Argon gas creates an additional barrier to heat loss and improves insulation
  • Solux-E® and Solux Ultra™ are Low-E coatings that reduce heat loss in winter and over-heating in summer. They protect your home's interior while providing a similar clarity to clear glass.

The Centrafix™ installation method recesses the joinery into the building wall, aligning the insulation elements - wall, window frame, glazing – to prevent cold air from circulating around the frame. This New Zealand designed innovation increases the thermal performance in your home by over 20%2.
