The most thermally efficient bifold door on the market

Thanks to the system’s combination of a unique thermal core and “warm aluminium” frame construction, WarmCore bifold doors are 25% more thermally insulating than most other traditional aluminium bifold door systems. U-values of just 1.0 W/M2K are readily achievable when triple-glazed, resulting in not only a warmer home, but a much more energy efficient one.

The system’s multi-chambered profile design ensures that any heat that would otherwise be able to escape your living space is successfully trapped, while also being fully concealed to never disrupt each panel’s modern aesthetic style.

Thermally efficient

Benefitting from weathertight and strong frames, aluminium bifold doors can effectively keep the heat in and cold out. Various additional hardware can be incorporated also such as and additional glazing to ensure your aluminium bifold doors always operate at peak thermal efficiency.
