Double Glazing Options.

Selecting the right double glazing for your aluminium doors and windows is essential for achieving optimal performance and aesthetics. The right choice of glass can significantly improve thermal efficiency, reduce UV radiation, minimize heat loss, and enhance comfort throughout the year.

At Windowmakers, we consider factors such as building orientation, shading, local climate conditions, and noise exposure to recommend the best double glazed windows. Our technical expertise ensures you make the right decision for maximum thermal efficiency, acoustic performance, and year-round comfort for your home.

The AGP System®

Our glass is sourced from AGP (Architectural Glass Products), a sister company of APL, renowned for delivering New Zealand’s leading double-glazing technology.

The AGP System® is a high-performance double-glazed argon filled glass unit engineered for superior thermal efficiency. With precision components that minimise heat transfer and maximize natural light, it meets the highest R-value standards set by the NZBC. Manufactured with advanced automation and cutting-edge technology, it guarantees exceptional thermal performance and consistent quality.

To achieve optimal thermal efficiency, it's important that the entire window system—aluminium window frames, double glazing, and installation—work together. The AGP System® Low-E glass with argon gas, paired with ThermalHEART® thermally broken frames, provides nearly double the thermal performance of standard double-glazed windows. Additionally, the Centrafix™ installation method enhances efficiency by an extra 20%.

What makes up The AGP System®?

ATS - Architectural Thermal Spacer®

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

Argon gas

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

Solux-E® or Solux Ultra™

Solux-E® and Solux Ultra™ are low emissivity (Low-E) glass coating options, which is virtually invisible and are applied to the inside surface of the exterior glass pane, protecting it from the elements. Both options 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.

How does Solux Ultra™ compare to Solux-E®?

Solux Ultra™ is the perfect blend of clarity, effective heating control, and superior fading protection, promising to maximise the benefits of your glazing.

  • It retains 9% more warmth in the home
  • It provides 23% more control over overheating
  • It results in a 10% increase in the reduction of fading

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).

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.

Low-E Glass Options.

With over 20 years of industry expertise, Windowmakers provides expert guidance to ensure your double-glazed windows comply with regulatory standards and deliver optimal building performance. Low-emissivity (Low-E) glass is now mandatory for new builds under Clause H1 of the NZBC. As part of The AGP System®, both Solux-E® and Solux Ultra™ are engineered to meet these requirements and deliver significant benefits.

Solux-E®

Solux-E® is the standard Low-E glass coating in The AGP System®, applied to the interior surface of the exterior glass pane. It reflects heat back into the building to reduce heat loss in winter, and in summer, it helps limit overheating by reflecting external heat away.

What are the benefits?

Year-round comfort

Solux-E® optimizes year-round comfort by minimizing heat flow, helping to keep the home warmer in winter and cooler in summer. It reduces warm air escape during winter and limits heat entry in summer without the need for tinted glass, also known as Solar Heat Gain Coefficient (SHGC).  

Solux-E® lets visible light enter while reflecting the sun's heat away, offering 34% better heat reflection than standard double glazing. This helps keep your home cooler in summer whilst reducing winter heat loss by 59%. 

Smaller energy bills

A more stable indoor temperature reduces the energy required for heating and cooling, resulting in year-round energy savings. This decreased energy consumption also eases the demand on New Zealand’s power grid, contributing to a lower environmental footprint. 

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

Solux-E® offers excellent light transmission and clarity, ensuring unobstructed views and keeping your home bright and airy. 

Protects against fading

Solux-E® helps protect your home’s furnishings from fading by reducing the amount of damaging light that enters through the glass. It provides 19% better protection than standard double glazing, helping to preserve the color and condition of soft furnishings and fabrics. 

Solux Ultra™

Upgrade to Solux Ultra™ for optimal clarity, overheating control, and fading protection. With superior solar control, Solux Ultra™ Low-E glass is recommended for those seeking to manage overheating and for buildings with a high window-to-wall ratio (WWR).

Why choose Solux Ultra™?

Superior thermal efficiency

Solux Ultra™ outperforms comparable existing Low-E glass products, delivering superior thermal efficiency and ongoing energy savings. 

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%* compared to the standard Solux-E® option. 

Controls overheating

Solux Ultra™ reduces overheating by an additional 23% compared to the standard Solux-E® option. High insulation levels and large window areas in modern home designs can result in frequent overheating. Solux Ultra™ works hard to let natural light stream in while allowing less heat to enter the home. 

Year-round comfort

Solux Ultra™ optimises year-round comfort by minimising heat transfer, enhancing thermal performance in both winter and summer. It reflects warm air back into the interior, reducing heat loss, and limits solar heat gain without the need for tinted glass also known as Solar Heat Gain Coefficient (SHGC). 

Protects against fading

Solux Ultra™ enhances fading control by an additional 10%, protecting your interior furnishings from harmful light and helping them stay looking better for longer. 

Maximises natural daylight

Solux Ultra™ offers excellent light transfer and clarity, ensuring natural light and unblemished views with its brilliantly neutral colour, while providing improved temperature regulation. 

Smaller energy bills

A more stable temperature reduces the need for heating and cooling, resulting in energy savings throughout the year. Lower energy consumption also eases the strain on New Zealand’s power grid, helping to minimize the environmental impact. 

Comparing Solux-E® with Solux Ultra™

Improve your home's comfort with Solux Ultra™ Low-E glass, offering improved warmth retention, overheating control, and fading reduction.
