Bi-Folding Doors

“Doors that blur the boundry between rooms..”


What’s it made of?
Our PVCu Bi-Folding Doors are made with Liniar’s ModLok™ multi-chambered profile. Our Aluminium Sliding Patio Doors are made with Smart’s Visofold 1000 multi-chambered profile. Or, with Liniar’s new Alumina range, have the best of both worlds: with aluminium Bi-Folds that can also be foiled to give woodgrained finishes to match your Liniar windows perfectly. Typically, they are glazed with a 28mm thick toughened sealed unit, made with a sheet of toughened float glass and a sheet of Saint Gobain’s PLANITHERM® TOTAL+ Glass.
What makes it unique?
Being a bi-folding door means you can open up your inside space to your outside space. These doors will not only look great alone, but will match the profile and colour of our windows flawlessly. Liniar’s Alumina was designed to have the strength of aluminium, but the woodgrained foiled finish of their regular PVCu windows. Bi-folding doors can go round 90deg corners to have a seamless transition between the garden and the home.
