Low Emissivity (Low-E) glass
Low-E glass reduces heat loss and protects your home furnishings, carpets, and timber floors from harmful UV rays, which cause fading over time.

Standard Low-E 272
Good thermal performance in all seasons. Reflects heat away in summer and keeps heat inside your home in winter.

Low-E 340
Ideal for warm, sunny climates with the ultimate protection from the sun, without any tinting. Plus it still keeps heat inside during winter.

Low-E 366
Superior thermal performance in all seasons. When paired with low-E i89, it can evan achieve better thermal performance than our standard triple glazing.

Low-E 180
Ideal for colder climates or homes with passive solar heating, it traps the warmth of the sun inside keeping your home cozy. Plus it still performs well against bright summer sun.

Low-E i89
A second layer of low-E added to maximise total performance, especially in colder climates.

Neat+™ Glass
Adds a layer of Neat+™ coating outside which reduces dust and grime on the glass.
Insulating glazing spacers
Insulating glazing spacers are used in all double glazed joinery to hold the panes of glass in place. In our joinery, they are also used to create an air-tight compartment for our standard argon gas filling.

Standard Intercept® Spacer
Included in all of our glazing units, the Intercept spacer is made from foam encased steel and tin, ensuring stregth and durability. Its U-shape construction allows for flexibility in response to thermal expansion in the glass.

XL Edge™ Spacer
An optional upgrade for those wanting the absolute best performance, the XL Edge™ spacer is made from a staggered stainless steel, with two sealant layers and desiccant fill.
