Glazing choices are an important option to consider. Glass can enhance the way your home looks and feels, but it also adds to the warmth and thermal efficiency of your home.

It’s a good idea to work through your options to find the right glass for your home. With options to reduce UV, minimise heat loss, and increase year-round comfort, your decisions can have a significant impact on the performance of your glazing. Low-emissivity glass is now a requirement for new builds, as per clause H1 Energy Efficiency of the New Zealand Building Code. We have different glass options that meet all the R-Value requirements for all six zones.  

Some factors to consider and discuss with your manufacturer are the orientation and shading of your home, the climate and noise around where you live.  Here is an overview of our high performance glass offerings, with two Low-E glass options to choose from and AGP's insulated glass unit, The AGP System®

The AGP System®

Your windows and doors are a complete system with each component contributing to the overall performance and comfort of your home. AGP are committed to ensuring each component performs at the highest level, which is essential for a warm, comfortable, healthy home. 

That's why AGP have introduced a high performance insulated system, The AGP System®, to New Zealand homes.

Designed to deliver the ultimate thermal performance and comply with the Building Code's highest R-value.

What is The AGP System®?

Solux-E® or Solux Ultra™

Both of these low emissivity (Low-E) coatings are applied to the inside surface of the exterior glass pane, protecting it from the elements. The coating is virtually invisible. Solux-E® and Solux Ultra™ both improve the level of insulation of the home, by reflecting the heat back to the inside, reducing winter heat loss through the glass. The reverse happens during the summer helping to limit overheating.

Argon gas

An invisible inert gas which is used as an insulator to create an additional barrier to heat loss in winter and heat gain in summer, improving thermal performance.

ATS - Architectural Thermal Spacer®

A thermally improved spacer that bonds the two glass panes of your double-glazed windows and doors apart and creates an airtight bond to ensure the best gas retention of argon gas used in The AGP System®.

Bonded to glass and secondary sealant

A continually evolving formulation used to ensure durable bonding between glass panes. This creates an airtight seal for the space between panes, providing additional protection for the primary seal.


Year-round comfort and energy savings

Solux-E® has a low emissivity (Low-E) coating applied to the glass, which is virtually invisible. The Solux-E® coating reflects the heat back to the inside, reducing winter heat loss through the glass. The reverse happens during summer helping to limit overheating.

Year round comfort

Solux-E® works hard to minimise heat flow allowing you to stay warmer through winter and cooler through summer. You'll have less warm air escaping in the winter and less heat entering through the glass in summer without the need to use tinted glass, also known as Solar Heat Gain Coefficient (SHGC).

Smaller energy bills

Smaller energy bills

A more constant temperature means less energy used to heat and cool the home, providing energy savings year-round. Reduced energy consumption puts less demand on New Zealand’s power grid, reducing the environmental footprint.

Protects against fading

Protects against fading

Solux-E® reduces the amount of damaging light coming through the glass, reducing fading in soft furnishings and fabrics.

Maximises natural daylight

Maximises natural daylight

Solux-E® provides excellent light transfer and clarity, keeping the view crystal clear and the rooms in the home light and bright.


Solux Ultra™

The perfect blend of clarity, overheating control and fading protection.

Due to its superior solar control, Solux Ultra™, is the best choice for homeowners wanting to control overheating and is highly recommended for buildings with higher window-to-wall ratio (WWR).

Why choose Solux-Ultra™?

Protects against fading

Solux Ultra™ delivers an additional 10%* increase in fading control, protecting your interior furnishings to keep them looking better for longer.

Controls overheating

Stay comfortable inside with a further 23%* reduction in overheating. High insulation levels and large window areas in modern home design can result in frequent overheating. Solux Ultra™ works hard to let natural light stream in with less heat entering the home, reducing overheating and also minimising the need to use air conditioning.

Retains heat

Solux Ultra™ reflects the warm air in the home back into the house rather than escaping through the glass, retaining heat by a further 9%*. This reduces the energy needed to keep the home warm in cooler months.

Maximises natural daylight

The brilliantly neutral colour of Solux Ultra™ sets it apart from other Low-E glass and ensures you enjoy natural light and unblemished views all while delivering improved temperature and fading control.
