Creating comfortable & energy-efficient spaces
Selecting the right glass for your windows and doors is essential to creating a comfortable and energy-efficient home or commercial project.
Glass is the only building material that insulates us from temperature extremes, while also controlling the flow of light and heat into and out of our spaces.
When choosing glass, there are three key factors to consider: natural light, solar heat gain, and thermal conductivity.
With the right selection, you can enjoy your views and natural light while managing UV and glare. The right glass helps harness the sun’s warmth in winter and minimise its effects in summer, while also improving insulation against unwanted heat loss or gain.
Performance glass can even help overcome site limitations so you can still enjoy light and views without compromising energy efficiency.

Types of glass for windows & doors
Clear float glass (annealed)
- Colourless, distortion-free glass with high light transmission.
- Standard base product for many performance glasses.
- Provides no additional insulation or solar control.
- Shatters into sharp shards if broken.
Tinted glass
- Made by adding metal oxides during manufacturing.
- Reduces heat and glare, available in Grey, Green, Bronze, and Blue.
- Offers solar control but limited insulation benefits.
- Shatters into shards if broken.
Reflective glass
- Features a metallic coating for greater solar control and reflective appearance.
- Available in Clear, Neutral, Green, Grey, Bronze, and Blue.
- Limited insulation benefits.
Toughened glass
- Grade A safety glass, stronger than annealed glass.
- Shatters into small, less harmful pieces.
- Available in Clear, Tinted, Reflective, and Low E options.
Laminated glass
- Two or more layers bonded with an interlayer.
- Holds together if broken, reducing injury risk.
- Can provide insulation, security, and soundproofing benefits.
- Available in Clear, Tinted, Reflective, and Low E options.
Low E glass
- Features a thin metallic coating that reflects heat radiation.
- Improves insulation by reducing heat transfer.
- Available in Clear, Neutral, Blue, Green, and Grey.
Double glazing (IGUs)
- Two panes bonded with a spacer, often filled with Argon gas.
- Provides significant insulation in extreme climates.
- Can be combined with Low E, Laminated, Toughened, Tinted, or Reflective glass.
