Bi Fold Doors

ModLok™ bi-fold Doors

Liniar’s ModLok™ bi-folding doors offer a totally unique option, thanks to the patented exoskeleton design giving them unparalleled strength, security and durability. No other uPVC bi-folding door has been tested to over 127,000 full opening cycles; and with low U-values, PAS:24 and Secured By Design accreditation, the Liniar ModLok™ is in a class of its own – earning the accolade of a Queen’s Award for Enterprise in Innovation in 2017.

Ideal for large openings, ModLok™ bi-folds enable you to open up an entire wall of your room – creating space and letting fresh air and natural daylight flood into your home.

Stunning alternative

Whether you have a bedroom with Juliette balcony, a kitchen-diner, a conservatory or an orangery, Liniar ModLok™ bi-folding doors can provide a stunning alternative to patio or French doors. Available in wide choice of opening configurations and colours, the Liniar ModLok™ bi-fold has ultra-slim sightlines, providing rooms with a clean, modern appearance.

Safety features include the innovative low threshold option for family friendly and wheelchair use. What’s more, Liniar bi-fold doors offer high energy efficiency, combined with the best security features on the market – bringing you a modern space-saving solution for your home that will definitely give it the ‘wow’ factor.

Better for the environment

One of the most effective ways you can save energy within your home is through installing energy efficient windows, doors and roofs. Liniar frames outperform the majority of other leading brands in the UK when it comes to thermal efficiency – mainly due to our innovative uPVC multi-chambered profile design.

The thermal efficiency of a door is measured in U-values, which demonstrate how effective the door is at preventing the transfer of heat into and out of a building. The lower the U-value, the higher the doors’ effectiveness at keeping the heat inside your home when it’s cold outside.

For greater thermal efficiency, the Liniar ModLok™ bi-folding range can be fitted with triple glazing, reaching an impressive U-value of 1.0 W/m²K, which means you’ll be able to enjoy a warmer and quieter home as well as lower energy bills.

ModLok™ Bi-fold Doors

A grand design

Bi-folding doors are becoming more popular than ever before, thanks in part to their regular appearance in television home make-over and lifestyle programmes.

Timber and aluminium are often perceived as the only materials that can be used for bi-folding doors, but doors made from lead-free uPVC can actually offer many benefits:

  • Smoother operation
  • Higher thermal efficiency
  • Low maintenance
  • Exact matching with your other doors and windows

Superior efficiency

With Liniar’s foiled woodgrain-effect options, your bi-folding doors can emulate the natural look of timber and you will never have to treat, sand or repaint them. If you choose our flat grey frames, your bi-folding doors will rival any comparable aluminium range on the market, offering superior energy efficiency at a more cost effective price.

And Liniar’s ‘top of the range’ ModLok™ bi-fold doors offer even greater strength and rigidity, combining all of the structural benefits of an aluminium door set with the energy efficiency of uPVC.

All Liniar bi-folding doors are ‘bottom rolling’, not top-hung – meaning no extra stresses are placed on your building’s lintel.

Benefits

  • Low Maintenance

    You can rest assured that you won’t need to spend hours looking after your set of Liniar bi-fold doors to maintain their beauty.

    Unlike timber, you won’t need to treat or paint them each year to keep them in top condition – and that’s not all; our 10 year frame guarantee gives you the peace of mind that the colours won’t fade.

    All that is needed to keep them looking their best is an occasional quick wash with soapy water.

  • Family Friendly

    The Registered Design protected Liniar low-threshold option provides a seamless point of entrance and exit, making it perfect for family homes.

    An optional tray to seat the low threshold creates an easy-access ramp for wheelchairs and prams without the need for messy and expensive excavation.

    Ultra-low, the Liniar threshold measures just 24mm at its highest point, with silver or gold finish options to perfectly complement the door hardware.

  • Innovation

    Slim hinges with internal hidden fixings, not only maintain the sleek lines but enhance security as they can’t be unscrewed from outside.

    We wanted to offer a low threshold, without the need for expensive and messy excavation, so we designed our own clever solution.

    We’ve even designed folding keys, to avoid any problems with keys being left in the locks during operation – it’s often the small things that make a huge difference.

  • Open up Your Business

    Not just for the family home, Liniar bi-fold doors can bring a whole new dimension to your commercial or business property.

    Maximise floor space at your pavement café by opening up an entire wall in the summer months, while knowing your energy efficient Liniar bi-fold doors will also keep in the heat during the winter.

    Give your showroom a new lease of life by installing Liniar bi-fold doors for ease of access, together with the highest possible security.
