Elegant sliding folding doors

What is a PVCu Bi-Fold Door?


Bi-fold doors are the perfect solution to transform virtually any property, let the light flood in, seamlessly gliding open to merge the lines between home and garden, creating the ultimate living space. The Duraflex PVCu Bi-Fold is a beautiful alternative to our French or Patio Doors and has been meticulously designed for ease of fabrication and to deliver superior performance across security, weathering and durability. Featuring the highly sought-after contemporary slim sightlines, a range of low threshold options and an extensive selection of design and configuration options, it’s a hugely popular addition to the Diamond Suite. Available in our comprehensive range of foil finishes as well as featured or bevelled profile options.

Benefits of a Bi-Fold Door


A Bifold door can maximise the amount of available space and blend it perfectly with the inside and out. Often chosen by homeowners as the main feature of a new extension, it can transform your way of living. This modern design can create one large living space incorporating the outside area with a Kitchen, Lounge or Diner. Our Bifold door has energy efficient glazing that retains radiator heat. Fully reinforced frames, internal beading, 5 point locking system and slave handles with shootbolts prevent forced entry.



PVCu Bi-Fold Doors are available in an extensive range of foil finishes, from our authentic woodgrain effects such as Antique Teak and Irish Oak, to contemporary solid colour finishes such as the popular Anthracite Grey and Chartwell Green; all designed to satisfy the most discerning homeowner.

Whitegrain, Rosewood, Irish Oak, Golden Oak, Anthracite Grey, Black.

Lead doors will have lever handles available in white, gold, chrome, satin chrome & black. Slave handles and hinges are available in white, black or satin chrome. The master door is fitted with a 5 Point Locking system and the slave doors have shootbolt mechanisms.

Additional Options

Trickle vents have to be specified on new buildings or extensions but for replacement doors they are personal preference. Trickle vents help reduce condensation and allow constant airflow in the room.



All doors are double glazed. The inner pane has an obscure backing glass and the exterior pane has a decorative design.


Toughened Glass

Toughened glass is about 5 times stronger than ordinary glass of the same thickness.

Pilkington Toughened Glass is manufactured by subjecting the final glass size to a heating and cooling treatment.

A balance of high compressive stresses at the surface and tensile stresses in the centre of the glass increases its strength.
