Choosing French Doors for a patio. Styles, materials and costs

French doors for a patio remain one of the most popular door types. Suitable for modern or traditional homes, available in a choice of materials, styles and aesthetics, today’s choice in French doors for a patio is better than ever.

As a leading independent source of expert guidance on French doors, here is everything you need to know about choosing the right French doors for your home in aluminium, PVCu, timber, steel and composite materials.

Why French doors make one of the best patio door choices

Designed right, French doors for a patio are one of the most affordable ways to change your dated doors. Depending on the type, they’re cheaper than a sliding or a bifold door, more functional and better for doors you use a lot in the home. And the right product can still provide the seamless connection between indoor and outdoor spaces that bifold and sliding doors make great claims to. Overall a French door, with or without matching side or top panels, creates a symmetrical, visually appealing design that enhances both aesthetics and functionality.

Unlike bifold doors, which fold away to the side and aren’t that useable in a two panel design, or sliding doors that lose you half or two thirds of your available opening, French doors provide a clear, and full opening. Opening in or out, with a choice of which door you open first. And low-threshold options for a minimal step provide smooth transitions between spaces, enhancing accessibility for everyone, from wheelchair users to families with pushchairs.

Today’s modern doors should all meet current Building Regulations in any material, but the U-Values you get will depend on the glass specification provided. Trickle vents are likely to come as standard as will toughened safety glass throughout. Colour choices are substantial across most materials, with aluminium providing the most colour options.

Your new doors will provide the same functional benefits described earlier in any material. However, each materials does come with it’s own characteristics for French doors. Let’s now explore these.

Aluminium French doors

Aluminium doors are slimmer, stronger and lower maintenance than other materials. The advantage of aluminium doors is that they are possible at wider and taller door sizes than PVCu, timber and composite French doors.

When replacing patio doors, the size of your structural opening will have an impact on the number of doors and fixed panels. Take a look at the door configuration options:

DOOR OPENING WIDTHDOOR CONFIGURATION
Up to 2 mSingle and the classic double French door works well, opening inwards or outwards. You can get away with slightly narrower options by having smaller panels.
Over 2 mDouble doors with one or two side panels work best for openings between two and four metres.
Over 4 mLarger existing or new extensions extend your options to having more than one double door set or a combination of double or single doors with side and top fixed glass panels. A good installer can help you design the most suitable option.
