Beautiful Woods

Eight species of sustainably grown woods are available to choose from.

Interior finish

Bring out all the beauty of your wood joinery with your choice of finishing Ultra Stain, or show a bit of modern flair with a painted Ultra Coat interior. Both Ultra Stain and Ultra Coat are so tough, they resist scratching and marring, and so superior, they provide advanced protection against moisture.

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. Reflects heat away in summer and keeps heat inside your home in winter with 95% UV protection.

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.

Obscured and decorative glass

Decorative grilles

Make your windows uniquely yours by upgrading to a divided light, removable wood, or between the glass grilles. Our divided light and removable wood grilles are available in a range of profiles and exterior finishes to suit your home. Maintenance free between the glass grilles are available in 16mm or 25mm contour or 16mm flat profiles.
