Bifold Doors For Your Patio
Bifold doors are ideal when you want to make the garden feel like a natural extension of your living space. Rather than sliding one panel behind another as with slidingndoors, the individual glazed panels fold and stack neatly to one or both sides, allowing you to open up almost the full width of the doorway. On warmer days, this can completely change the way you use a kitchen, dining room or living area, creating one flowing space between indoors and outside.
When the doors are closed, the large glazed panels still provide plenty of natural light and wide views of the garden. Modern aluminium bifold doors combine slim sightlines with the strength needed to support larger areas of glass, giving them a clean, contemporary appearance without compromising on security or performance.
There is plenty of flexibility in the design too. The number of panels, opening configuration and direction of travel can be chosen to suit the size of the opening and how you want to use the doors. You can also choose from a wide range of colours and finishes, including different colours internally and externally.
Aluminium Sliding Patio Doors
Aluminium sliding patio doors are a good choice when you want large areas of glass, slim frames and wide, uninterrupted views of the garden. The strength of aluminium allows for larger glazed panels with narrower sightlines, bringing more natural light into the room and giving the doors a clean, contemporary appearance.
The sliding design is particularly useful where space matters. Because the doors move horizontally along their track rather than opening inwards or outwards, you can use the space immediately inside and outside the doors without allowing room for a door swing. This makes them well suited to kitchens, dining areas and rooms opening directly onto a patio or terrace.
Large panels can be configured in different ways depending on the width of the opening and how much access you want to create. Modern sliding systems are designed for smooth, easy operation, so even substantial glazed panels can be opened and closed comfortably.
Thermally efficient aluminium frames and modern double glazing help keep the room comfortable throughout the year, while robust frames and multi-point locking provide security. Aluminium is also exceptionally durable and low maintenance, with no need for regular painting or treatment.

French Doors
French doors are a classic way to open your home onto the garden, with two glazed doors that meet in the centre and open outwards or inwards to create a generous opening. Their balanced, symmetrical design works particularly well with traditional properties, although modern frame styles and colours make them equally suited to newer homes.
With both doors closed, the large glazed areas bring plenty of natural light into the room and provide a clear view outside. For everyday use, you can simply open the main door, then open the second door when you want the full width for entertaining, moving furniture or creating a more open connection with the patio or garden.
French doors are also a practical option for openings that do not need the width of a sliding or bifold system. Because there is no fixed central frame when both doors are open, they provide excellent access without requiring a particularly large opening.
Modern French doors combine the traditional appearance with energy-efficient glazing, secure multi-point locking and low-maintenance frames. They are available in a wide choice of colours, finishes, glazing options and hardware, allowing the doors to complement the style and character of your home.
Over 200 Colour Options
You have far more choice when it comes to colour and finish with aluminium windows and patio doors. At Prior Products, we offer a selection of popular colours with short lead times, including White, Jet Black, Anthracite Grey and Anthracite Grey on White. These shades suit many modern homes and extensions and remain some of the most frequently chosen options.
If you are looking for something more individual, aluminium can be powder coated in over 200 colours from the RAL colour chart. This allows you to match existing features, complement brickwork or create a distinctive architectural look. Finishes are available in matt, gloss or textured coatings, depending on the style you prefer.
There are also additional specialist colour collections available with metallic, anodised and textured finishes that bring even more design flexibility.
With such a wide choice, aluminium windows and patio doors can be tailored to suit both contemporary and traditional homes while maintaining the durable, long-lasting finish that powder-coated aluminium is known for.
What type of patio door is best?
The best patio door depends on the size of your opening, the space available and how you want to use it.
Sliding patio doors are ideal for large areas of glass without needing space for the doors to swing open.
Bifold doors can open up most of the width between your home and garden, while French doors are a popular choice for smaller openings and more traditional properties.
Patio Doors Stratford-upon-Avon
What is the difference between sliding patio doors and bifold doors?
Sliding patio doors have large glazed panels that move horizontally along a track, with one panel sliding behind another.
Bifold doors use several narrower panels that fold and stack together at the side. Bifolds can create a wider opening when fully open, while sliding doors generally give you larger individual panes of glass and fewer frame sections across the view when closed.
Are aluminium or uPVC patio doors better?
Both can provide excellent performance. uPVC is a practical, low-maintenance choice and works well for many homes.
Aluminium is particularly suited to larger doors because its strength allows for slimmer frames and larger glazed panels. The right choice will depend on the size and style of the doors, the look you want and your budget.
Are modern patio doors energy efficient?
Yes. Modern patio doors combine energy-efficient glazing with insulated frames and effective weather seals to reduce heat loss.
Replacement external doors and glazing must also meet Building Regulations requirements for thermal performance.
Are patio doors secure?
Modern patio doors are designed with security in mind, with strong frames, toughened or safety glazing where required and multi-point locking systems.
The exact security features vary between door systems, so it is worth discussing the locking and glazing specification when choosing your doors.
Do I need planning permission to replace patio doors?
Usually not, if you are replacing existing doors with doors of a similar appearance.
Different rules can apply to listed buildings, properties in designated areas or homes affected by an Article 4 Direction.
Creating or significantly altering an opening may also need additional consideration, so it is worth checking before work begins.
Do replacement patio doors have to meet Building Regulations?
Yes. Replacement external doors are controlled fittings under the Building
Regulations and requirements cover areas including thermal performance, safety glazing and ventilation. Using an installer registered with an appropriate competent person scheme provides a route for certifying compliant replacement work.
Can I replace French doors with sliding patio doors or bifold doors?
Often, yes. An existing set of French doors can potentially be replaced with sliding or bifold doors, depending on the dimensions and structure of the opening.
If you want to make the opening wider, additional structural work may be required.
Which patio doors are best for a small space?
Sliding patio doors are particularly useful where space is limited because the panels slide along their own track and do not need clearance to swing into the room or garden.
French doors require space for the doors to open, while bifolds need space for the folded panels to stack.
Can I have a low threshold on patio doors?
Low-threshold options are available on some patio door systems and can make the transition between the house and garden easier.
The appropriate threshold depends on the door system, property and requirements for weather protection and access. FENSA notes that low-threshold options can be available with bifold doors.
