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.

Discover for yourself why more and more people are choosing Liniar’s bi-fold doors and benefiting from these versatile and attractive home improvements – and find out more about ModLok™ technology here.
