What are WarmCore doors?


Frequently recognised as the epitome of bifold door design, WarmCore doors are an inherently premium patio entrance style that delivers beauty without ever compromising on performance. Providing your home improvement budget allows it, once installed homeowners can immediately feel closer to the outside without conceding optimal levels of thermal efficiency. WarmCore doors expertly balance both, redefining the heat retention levels possible in wide span aluminium doors.


Prioritising thermal efficiency first and foremost

WarmCore doors take their name from the fact that they are engineered using a process known as “warm aluminium” frame construction. Carefully manufactured with polyamide thermal break integration that better works to reduce the threat of cold invading from the outside, U-values as low as 1.4 W/m2K are readily achievable. Your home will be warmer all year round, and energy bills lowered substantially.

Such high levels of thermal efficiency are usually unheard of within a bifold door system, even those engineered in high performance aluminium. This is what separates WarmCore doors from other rear entrance styles, utilising an innovative width thermal core while still accommodating additional double and triple glazing practices.

Cutting edge performance with built-in versatility

Strong, sleek, and secure, WarmCore doors are not only notable for their impressive thermal qualities, but hi-tech elegance and inherently strong construction too. Added security features such as dog bolts and integrated 5 point locking work in tandem with the aluminium frame’s natural robustness, resulting in a finished product that offers homeowners absolute peace of mind knowing that their home and family are kept safe and secure.

Each Warmcore door sash corner comes mechanically jointed for twice the strength, using a combination of internal aluminium cleats and a wrap-around corner moulding block to ensure resistance under even the most frequent usage. Whether you need them to be installed using 2, 5, or even 7 sash panel configurations to fit the widest of apertures, every unit comes supplied to meet the very best security and performance standards.

The perfect combination of style and performance

As technically impressive as WarmCore doors are designed to be, such contemporary advancements never impede the natural benefits bifold doors are known for offering. Slim sightlines and sleek frames allows for lashings of light to flood into the home, boasting wide open views of the outside to give the impression of a larger space that extends into the outside. Bifold doors operate effortlessly and seamlessly blur living spaces, WarmCore doors do this as standard.
