Understanding our Glass Range

We offer a range of glass options and coatings, which are explained in more detail below.

Thermal efficiency and U-Values

Modern glazed products are designed to give you the best possible thermal efficiency. They prevent heat escaping from your home, which saves energy and keeps your heating bills down.

The thermal efficiency of a product is indicated by its U-Value. The lower the U-Value, the more thermally efficient it is.

For example:

Glazing Typical U-Value
Single glazing 5
Double glazing 1.2
Triple glazing 1.0

To achieve these low U-Values, we use:

Argon-gas-filled units

All our double and triple-glazed units are filled with Argon gas. This improves the thermal efficiency significantly, keeping the warmth inside and the cold outside.

Warm edge spacer technology

This is standard in all our double-glazed units. It insulates the inside of the frame and prevents condensation from forming around the bottom.

Glass thicknesses

In most double-glazed units, the standard thickness of each glass pane is 4mm. Float glass and toughened safety glass can be manufactured using these 4mm panes.

Optional coatings

Adding a coating to your glass can improve energy efficiency, reduce the need for manual maintenance and maintain a comfortable temperature.

Low emissivity coating

An optional, invisible coating designed to reflect heat back into your room for better heat retention. This coating alone could help you save money on your energy bills.

Self-cleaning glass

This coating uses UV rays from the sun to break down dirt on the surface of the glass, so the rain can wash it away. During dry spells, a hose down with plain water will have the same effect.

To maximise the longevity of the coating, no cleaning products should be used on the glass. The coating is supplied as standard on our roof lanterns and may be applied to other products on request.

Solar control coating

Direct sunlight on your glass builds heat in your home, creating an effect that is similar to a greenhouse.

This coating blocks infrared radiation and maintains a cooler temperature during hot weather. It is particularly helpful if your property is south facing and has large expanses of glass, such as bi-fold or sliding doors.

The coating is supplied as standard on our roof lanterns and may be applied to other products on request.

Glass for safety and security

If safety and security is a priority, we offer two further glass options.

Toughened safety glass

All our doors are glazed with toughened safety glass as standard. The glass conforms to British Standards, as denoted by the kite mark in the corner.

Toughened glass is stronger than normal glass and, in the event of a breakage, will shatter into small fragments rather than dangerous shards.

Laminate glass

This glass is used in cases where safety and security are paramount.

Laminate glass:

  • Protects against intruders
  • Acts as a safety barrier — for example, on a Juliet balcony that doesn’t have a handrail
  • Is used to create the multi-storey glass curtain walls you sometimes see in shopping centres.
  • Laminate glass also restricts the amount of UV radiation that can pass through it. The filtered light is much safer on your skin and prevents the sun’s rays from bleaching your furniture.
