Built around a belief that beauty doesn’t have to compromise performance, WarmCore® products were created out of a desire to combine the desirability, durability and flexibility of aluminium with unparalleled insulation.

Fold Doors

Depending on the opening configuration, the WarmCore® fold can be configured to open inwards or outwards up to 6 metres, with up to seven opening sashes that glide along custom tracks.

With numerous colour and configuration options, you will be making a great choice in choosing the WarmCore® fold as an energy-efficient solution for your home.

Windows

The unique full-width thermal core is key to why WarmCore® windows are thermally more efficient than traditional aluminium systems and provide an ideal solution to help you save money on your energy bills.

Available as casement or tilt-and-turn windows, and with a flush sash option that brings the outer frame perfectly level with the opening part of the window.

Entrance Doors

Revolutionising Energy Efficiency

Although aluminium is renowned for its strength and durability, it traditionally allows heat to escape easily, leading to colder interiors and increased heating bills. Many aluminium window and door systems address this issue by incorporating a small thermal break of less conductive material to reduce heat loss.

WarmCore®, however, took a groundbreaking approach from the outset. It revolutionised the window and door industry by designing a system that prioritises thermal efficiency without compromising on strength. The outer face of the profile is crafted from high-grade aluminium, strategically positioned to provide excellent structural rigidity while maximising thermal performance.
