The importance of window systems

The combination of products (the frame, the glass, and in some cases, the installation) that make up a window or door are considered a window system. Like any system, the way the components interact and work together has an impact on the overall performance. Altherm Window Systems offers thermally efficient solutions for each component of your window system to deliver the ultimate thermal efficiency and home comfort.

The ThermalHeart+® window system

In this system, ThermalHeart+® frames are combined with The AGP System® glass, resulting in almost double the thermal performance of the whole unit when compared to standard, non-thermally improved aluminium joinery.

The AGP System®

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® is a low emissivity (Low-E) coating that reduces heat loss in winter and over-heating in summer. It protects your home's interior while providing a similar clarity to clear glass.

Centrafix® Installation

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.
