Easy Clean Glass
When you add the optional Simply-Clean® coating to your windows, the sun will actually help to keep your windows clean. As the sun`s rays contact the coating, Simply-Clean® is activated and you won`t have to clean the windows as often.
Premium Heavy Duty Hardware
Every window comes standard with Premium Quality Hardware built to last a lifetime. Available on awning and casement windows Multi-Point locking hardware with our fold-down handles is sturdy and adds to the security of your home.
Insect Guard Fly Maze
As a standard practice, our windows have a sponge-like insect guard inside our hollow multi-chamber frames. This prevents insects from nesting or entering through a window frame.
Fusion Welded Sash & Frame
Each sash and frame is precision-mitered, then fusion welded using extreme heat and pressure. This ensures a virtually inseparable bond at every joint.
Lead-Free MultiChamber PVC Frame
Designed to draw moisture away from the window to the drains, reducing condensation and the formation of mould.
Triple Weather Seals
These seals are oversized for higher performance and built into the frame to prevent any air transfer, allowing for a completely sealed unit.
Solar Bond Paint
There are thirteen standard window colours for you to choose from. We can also custom colour match your windows, so they co-ordinate with any existing outdoor decor finishes.

Zero Defects
Our attention to detail ensures consistent quality. Rather than just examining our quality at the end point, our quality control embedded at every step of the process, ensuring premium quality for every window.
