An attractive alternative to patio or bi-folding doors, Liniar’s range of French doors are an ideal choice where the aperture size is more limiting.
Offering a more traditional aesthetic, Liniar’s stunning range of uPVC French doors come with the same high specification and colour choices as our window range – just as you’d expect.

Available in either an ‘open in’ or ‘open out’ style to suit your living space, the Liniar French door provides your home with a beautiful and secure entrance – along with a range of patented low and ultra-low threshold options.

Ensuring you enjoy the maximum amount of natural light in your home, the fully sculptured features of the Liniar French door provides a beautiful finish.
Liniar French doors are not only lead-free and aesthetically pleasing but have been created with security in mind.
A vital component of all Liniar products is security and our doors are fully accredited to meet the necessary standards, including Secured by Design and PAS 24, plus they are fully compliant with the latest relevant divisions of the Building Regulations.
