Which New Patio Door is Best?

Do you want to maximise the daylight coming into the room?

Do you want to maintain wall space at the sides to place furniture or curtains?

Will you want to fully open up the whole wall to seamlessly integrate with the outdoors?

The size of the opening often lends itself to a particular type of door.

At Heath Windows and Doors, we will help you explore the options so that you choose the right solution that you will love for many years.

What Are You Replacing?

You have a lot of options for your patio doors. You may be led by the existing space. If you already have french doors or are replacing a window the cheapest option may be to use the existing width of the opening. For instance, changing a simple 2 door set up to a full wall width set of bi-folding patio doors may require a new lintel. Changing old sliding doors to French doors may require additional brickwork or you could choose glazed panels to fill in the extra space.

The first thing to think about is the look that you like. You’ll only do this once, so we encourage you to think carefully about what you want. We’ll advise you about the practicalities of your choice.

Aluminium Patio Doors

Aluminium patio doors are known for their durability, strength, and modern style. These doors are made from lightweight but strong aluminium frames and large glass panels that allow for plenty of natural light to enter the room.

Aluminium patio doors come in a variety of styles, including sliding, folding, and French doors, and are available in a range of colours and finishes to complement different home designs. Because of their strength and durability, aluminium patio doors require minimal maintenance and are resistant to rust, warping, and other types of damage. 

uPVC Patio Doors

UPVC patio doors are a popular choice for homeowners who want a cost-effective, low-maintenance option for their outdoor living space. UPVC stands for unplasticized polyvinyl chloride, a durable and weather-resistant material that is commonly used in the construction of doors and windows.

UPVC patio doors are lightweight and easy to install, and they come in a variety of styles and finishes to complement different home designs. UPVC patio doors require very little maintenance and are resistant to rust, rot, and fading. With their affordability and practicality, UPVC patio doors are a popular choice for many homeowners looking to enhance the functionality and appearance of their outdoor living space.

Bi-folding Doors

Bi-folding doors are perhaps the most flexible of all your choices. They can be configured to open in the centre or sides. You can do this with sliding doors too. What is unique about bi-fold doors is that they can all fold to the side to create a completely open space.

Bi-folding doors make a larger area look even grander providing a full view of the garden and seamless integration with the garden. They work equally well for smaller living areas because they make the room look bigger. No matter where these doors are installed, they give a feeling of light airiness and sophistication.

Sliding Patio Doors

Sliding patio doors provide lots of natural light with less frame to interrupt the view. They can fit into an existing space, or you can expand your opening to fit across the whole wall.

Our sliding patio door frames have been designed with safety features to prevent slamming.

Sliding Doors are usually the lowest cost option for patio doors.

If space is limited, you can arrange furniture close to the doors as they open within their own tracks. They are also convenient for opening only a small amount without worrying about the wind catching the door.

French Doors

French doors are ideal for a wide range of uses, particularly when you want to maintain a traditional feel. Beautifully suited to open up into conservatories or to make a unique design statement within your home. French doors are often the practical choice for homeowners who want to replace a window so that they step out into the garden. Typically French Doors are chosen for smaller openings but are equally effective to create a glass wall effect by using two or three sets of French Doors.

Sometimes there is no choice if pillars are already in place but sometimes our customers just prefer the traditional look of French doors.

Aluminium French Doors for Classic Style

Aluminium French Doors are a great addition to any home. French doors are popular for opening up the back of one room rather than for wider expanses. As French doors are often smaller than other patio doors, they particularly benefit from the slimmer frames, allowing more view and light.

Our French doors are completely bespoke, crafted to your precise measurements with customisable colour and handle options.

Which Material is Best for Patio Doors?

Aluminium is stronger than timber or uPVC and can support larger expanses of glass on thinner frames. This minimises the framework and looks slightly more modern. Aluminium frames tend to have a more minimal profile which also contributes to the sleeker look.

Due to the strength of aluminium, it can be used for much larger glass areas. We will usually recommend aluminium for wide sliding doors and bi-fold doors. Aluminium door frames are also resistant to flexing or twisting, and very well suited to variable temperatures as they don’t expand and contract with heat variation. This means they are a great choice for coastal locations or places where they are frequently exposed to direct sunlight.

What are French Patio Doors?

French patio doors are the same as French doors. They are a pair of doors that are often used to connect indoor and outdoor spaces in homes or buildings. They are typically made of glass and consist of two doors that open from the middle and swing outward or inward. 

French patio doors are designed to let in natural light and provide easy access to outdoor areas, such as patios, decks, and gardens. They are often used in living rooms, dining rooms, and bedrooms, and can enhance the overall appearance and functionality of a space. French patio doors come in a variety of sizes and styles to fit different architectural styles and design preferences.

Are Aluminium Patio Doors Cold?

Metal is a good conductor of temperature. If cold windows are in contact with aluminium frames the cold will transfer. In the past, aluminium windows have been thought to be cold because of this. Think back to the old Crittal windows and sliding doors of the 70s and 80s. Nowadays, most aluminium doors include a thermal break. The break is made of a less conductive material (Origin use polyamide) and sits between the interior and exterior faces of the frame to manage heat loss.

Are Patio Doors Environmentally Friendly?

Aluminium doors can be environmentally friendly from more than just a thermal efficiency point of view. Aluminium is widely recycled and many companies make their doors from recycled metal (Origin recycles 100% of all scrap aluminium produced when manufacturing their products).

Whether you choose uPVC or aluminium, be careful about cheap deals as you could pay for it in the long run.

uPVC patio doors are usually cheaper than aluminium doors, but given how long you expect them to last, a per year price isn’t very different.

Are Patio Doors Energy Efficient?

All bi-fold doors must have a U-value of at least 1.8W/m2. All of our doors meet or exceed this requirement. Bear in mind that installation can affect thermal efficiency. Some cheap Upvc products are prone to warping, which can affect thermal efficiency.
