TIMELESS IN APPEARANCE AND ROBUST ENOUGH TO IMPRESS A QUEEN

No other PVCu 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 ModLokTM 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, ModLokTM 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.

SUPERIOR EFFICIENCY

And Liniar’s ‘top of the range’ ModLokTM 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.
