25% More Thermally Efficient

What sets Warmcore apart is its unique full-width thermal core. Unlike traditional aluminium doors, which often struggle to retain heat, Warmcore bifold doors are up to 25% more thermally efficient. This translates into better insulation, lower energy bills, and increased comfort all year round. The thermal core technology helps maintain a comfortable indoor environment while reducing your home’s environmental impact — a smart investment for anyone looking to enhance energy efficiency without compromising on style.

Secure Operation

With custom-made roller assemblies positioned deep within both the top and bottom tracks, our system offers enhanced strength and security. This design not only ensures smoother, more reliable operation but also makes the doors more resistant to tampering and wear over time. By placing the rollers securely within the frame, the overall structural integrity is improved, providing homeowners with greater peace of mind and long-lasting performance.

We understand that not every shade fits all homes, which is why we offer a selection of colour combinations, including wood grain finishes to help tailor a Warmcore bifold door to any home or style of property.

High Performance

Our Warmcore bifold doors are built for durability and all-weather performance. Each unit features triple weather sealing on all sash interlocks, offering excellent protection against the elements. Whether facing wind, rain, or cold, these doors help keep draughts at bay and ensure that the interior remains dry and warm. This level of sealing also contributes to better noise insulation, creating a more peaceful indoor space.
