Bi-folding Doors

Taking open plan living to a whole new level, folding sliding doors, or bi-folding doors as they are now commonly called, have the unique ability to seamlessly connect your indoor living space with your garden. Bi-fold doors are a contemporary way to transform your home and enhance your lifestyle – allowing air and light to flood in to create stunning living areas.

Available in aluminium, PVCu or timber, our bifold doors can be manufactured folding to the left, right or to both sides, and depending on the folding option chosen, can incorporate a traffic door which can be used like a normal external door, leaving the other panels locked in place. For practical reasons most people choose to have their doors opening outwards, however, they can be manufactured to open inward if required.

Compared to windows and standard doors, bi-folding doors are more complicated. They have more moving parts and tolerances are much tighter, as a result, precision is required at all stages, from survey through manufacture, and finally the installation itself. In order to ensure long-term, trouble-free enjoyment of your doors, a meticulous installation is essential. By choosing Silika you can rest assured that your bi-folding doors will be installed by experts.

Aluminium Bi-folding Doors

We offer five premium quality aluminium bi-folding door systems – AluK, Smarts, Schüco, and the next-generation aluminium doors – Alumina by Liniar and WarmCore® from Synseal

Key features include:

  • Robust, slim aluminium sections are used to minimise sight lines, thereby maximising the glass area and visibility when the doors are closed
  • Contemporary ironmongery in a choice of colours adds to the door’s sleek appearance
  • Powder coated in a choice of over 200 RAL colours* – including a dual colour option i.e. different colours on the outside and inside. For coastal locations, the coating can be upgraded to a marine-grade finish
    • We are now able to offer a powder coated oak wood structure finish which is not only very convincing and low maintenance, but is also cost effective when compared to real timber
  • Each panel can be made to a maximum of 1200mm wide and 3000mm high, allowing you to maximise the glass area
  • Ability to offer truly expansive openings – enabling you to enjoy open plan living to the full
  • Optional tilt and turn sash for extra ventilation available on certain systems
  • As much as 95% clear opening once folded back
  • Both AluK and Schüco offer a floating/movable external corner post option allowing you to completely open up the corner of your new extension giving the feeling of limitless space
  • The combination of a thermal barrier, multiple weather seals and high performing glass maximises heat retention, increasing fuel efficiency and helping to minimise fuel bills
  • The Alumina by Liniar door is the only fully sculptured bi-folding door available and suites perfectly with the Liniar PVCu window system. In addition, as well as being available in the full range of RAL powder coat finishes, it is available in numerous woodgrain and solid foiled finishes, again offering the ability to perfectly match the finishes available for the Liniar PVCu window system. Due to its innovative design it offers extremely high thermal efficiency – resulting in superb U-values as low as 1.2 W/m2K
  • The innovative Synseal WarmCore door offers unrivalled thermal efficiency – as low as 1.0 W/m2K, together with the widest range of design styles available
  • Double glazed as standard, there are various upgrades available including triple glazing and solar control glass
  • Option of both manual and motorised integral blinds, available in a range of colours
  • Several low threshold options are available, including a Part M compliant threshold which allows easy wheelchair and pushchair access. In addition, a flush-fitting threshold is available which allows the seamless integration of two rooms
  • High security multi-point locking fitted to the main doors; all intermediate panels have concealed steel shoot bolts that engage securely into the top and bottom tracks
  • Highly stable product unaffected by extreme weather conditions
  • Low maintenance

PVCu Bi-folding Doors

We offer the market-leading Liniar range of folding-sliding PVCu doors which have been purposely designed, incorporating many innovative design features not available on other systems.

Key features include:

  • Bespoke door sash profiles result in slimmer sight lines, maximising the glazed area
  • Doors run on in-board tracks, similar to aluminium bi-folds, as opposed to the PVCu industry norm of face fixed. As a result, the door sashes sit flush with the outer frame and the running gear and hinges are concealed – only the hinge knuckles are visible when the door is closed
  • Wide range of colours and finishes available
  • Bespoke hardware available in a range of colours
  • Each panel can be made to a maximum of 1000mm wide and 2150mm high
  • Can accommodate openings up to 6 metres wide
  • As much as 90% clear opening once folded back
  • The combination of multi-chambered PVCu profiles, multiple weather seals and high performance glass results in excellent thermal efficiency with U-vales as low as 1.0W/m2K
  • Double glazed as standard, there are various upgrades available including triple glazing and solar control glass
  • Option of both manual and motorised integral blinds, available in a range of colours
  • Several low threshold options are available, including a Part M compliant double ramp threshold which allows easy wheelchair and pushchair access. In addition, a flush-fitting threshold is available which allows the seamless integration of two rooms
  • High security multi-point locking fitted to the main doors; all intermediate panels have concealed steel shoot bolts that engage securely into the top and bottom tracks
  • Excellent weather resistance
  • Low maintenance
  • Offers much of the functionality and aesthetic of an aluminium bi-fold, but at a more affordable price

* RAL Colours are internationally recognised colour standards used by professionals in industry, manufacturing, architecture and design to cover a wide range of applications including powder coating
