Bi-Fold Windows

Bifold windows are a striking addition to any home, bringing the best that modern innovations have to offer. Folding neatly away, these uPVC windows offer unrestricted views and enhanced ventilation.

Thermally Efficient

All of our bi-fold windows are designed to keep you comfortable during the colder winter months. This is made possible through our cutting-edge multi-chambered design, achieving A+ standards of thermal efficiency.

Designed from Scratch 

Many other uPVC window profiles were designed using 20 year old technology - or even older. 

Designed completely from scratch in 2007, Liniar's multi-chambered bi-fold window is far more technically advanced than most other uPVC window systems available in Britain - it truly has been built for the challenges of today. 

Eco-Friendly 

As well as helping to keep more heat inside the property, Liniar bi-fold windows have always been 100% lead-free, well before legislation - you no longer have lead in your petrol or paint, so why choose to have frames containing lead? 

And on top of that, every element of Liniar uPVC bi-fold windows can be easily and fully recycled at the of end its lifetime.
