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.
Cardinal Low-E 272
Standard Low-E 272

Good thermal performance in all seasons. Reflects heat away in summer and keeps heat inside your home in winter.

Cardinal Low-E 366
Low-E 366

Superior thermal performance. This is our standard low-E on select products. When paired with low-E i89, it can achieve better thermal performance than our standard triple glazing.

Cardinal Low-E 340
Low-E 340

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

Cardinal Low-E 180
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.

Cardinal Low-E i89

Cardinal Neat+ Glass
Neat+ Glass

Adds a layer of Neat+ coating outside which reduces dust and grime on the glass.

Locking Hardware

Sliding and hung uPVC windows can be upgraded to feature automatic locks, which lock the window the moment it’s closed. Auto locks can be further upgraded to feature a pull-cord, which enables older people, people with limited mobility, or people in wheelchairs, to easily open and close their windows.

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
Standard Intercept® Spacer

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

Cardinal XL Edge Spacer
XL Edge Spacer
