French Doors

Capturing European charm, Liniar's range of double French doors feature glazed panes with a signature 'floating mullion' to offer heightened standards of accessibility for wider apertures.

uPVC French Doors

Liniar uPVC French doors offer an attractive alternative to bi-folding or sliding patio doors where apertures are wider than a single door. Comprising a set of two doors, French doors open either inwards or outwards, with the central mullion (bar) in Liniar doors fixed to the ‘slave’ door to provide a wide, fully opening expanse when both doors are opened.

Liniar offers a choice of two 70mm uPVC French doors (one standard, one flush) as well as 90mm ultra energy efficient uPVC French doors, along with a fully aluminium heavy duty option.

Highly Secure

All Liniar French doors can achieve Secured By Design and PAS24 levels of security for your family’s peace of mind. And the large expanse of double or triple glazed panes, combined with Liniar’s slim, multi-chambered profiles, means Liniar uPVC French doors and aluminium French doors both offer superb energy efficiency, preventing the transfer of heat from the inside to the outside and saving homeowners money on energy bills.

If you need taller or wider French doors, or anticipate heavy-duty usage, why not consider Alumina 70mm French doors? Offering a seamless flush finish, Liniar's aluminium range of French doors can be foiled to match Liniar windows and are ideal for pairing with flush sash or Resurgence flush windows.

French Door thresholds

When it comes to access doors, the threshold is important – and Liniar offers a choice of 8 different thresholds for French doors to suit your home and your budget. Choose from a standard frame-only threshold or add an external cill, low threshold or even a Part M compliant low threshold for mobility and pushchair access – your Liniar supplier will be able to advise on the most suitable option for your home.
