Bifold Doors


Modern Bifold Doors

Modern living is about creating spaces that work for you and your family, and adapt to the needs of the moment. Bifold doors were born from this ethos, and their flexibility helps your home become a space that works for you, integrating outside living space with interiors. Open and airy on beautiful summer days, warm and insulating in the colder months, bifold doors help breathe life and light into your home.

Warmcore® bifold doors are an innovative aluminium folding sliding door system with inward or outward-opening doors up to 6m wide, with as many as seven opening sections gliding along custom designed tracks. They are 25% more thermally-efficient than traditional aluminium systems, so that when they are closed the interior retains its heat, whilst the full-glazing allows the same panoramic garden view as when they are open.

Developed around a belief that beauty doesn’t have to compromise performance, WarmCore® aluminium folding sliding doors were created to combine the desirability and durability of aluminium with unparallelled insulation. The orange thermal core, hidden away in the finished doors, delivers a new high performance fenestration framing solution known as “warm aluminium”.

With a wealth of colour, style and configuration options, you can choose the perfect warm, secure and beautiful WarmCore® door for your home to create that real WOW factor. They come with class-leading security built-in, backed by a comprehensive 10 year product guarantee, reinforced by the ERA 5 star security guarantee.

Warmer by Design

The traditional weakness of aluminium windows and doors has been the aluminium itself. While a beautifully strong and hard wearing material, aluminium is a good conductor of energy, meaning that the warmth from your home finds an easy path outside, leaving you with higher heating bills. Most aluminium systems try to overcome this inherent weakness by replacing a section of aluminium with a polyamide thermal break to lessen this heat loss.

The WarmCore® system takes this a lot further, by constructing the door around a multi-chambered thermal core to reduce cold bridging, whilst retaining outer faces of high grade aluminium, positioned to add the greatest structural rigidity. The result is an innovative “warm aluminium” frame construction, ensuring market-leading thermal performance.

Unparallelled Security

Each element of the WarmCore® door combines to ensure optimum security, and every WarmCore® door is independently certified to PAS24:2012, the benchmark in enhanced security performance requirements in the UK. Custom-made roller assemblies sit deep within the top and bottom tracks, and the extruded aluminium hinges are inherently strong and secure.

Added security features such as integral dog bolts bind the door sashes together when closed, protecting against forced entry. A custom designed door lock, available on no other door system, uses a 5 point locking system with 3 opposed hook locks and twin shoot bolts that engage fully into the aluminium top and bottom tracks, all helping keep you and your family safe and secure.
