The Alumina bi-fold door by Liniar, with its stunning design and ultra low U-Value, is a step ahead of traditional aluminium bi-fold doors.

Customers have chosen Alumina bi-fold doors for a variety of reasons. Most trust the lineage behind the Liniar name and the long line of superior products from its Derbyshire manufacturing facility, others enjoy the ability to match Alumina bi-fold doors to existing or new Liniar PVCu windows and doors with foils or powder coating, and then there’s the flexible PVCu beading, which makes glazing easier for installers while also enhancing the product’s energy efficiency.

From the warm-touch exterior and polyamide thermal break providing excellent thermal efficiency to the ability to span up to seven panes wide and mimic the appearance of woodgrain finishes with foiling, the Alumina bi-fold door from Liniar is turning heads for all the right reasons.
