What are Patio Doors?
Patio doors is often a general term for any type of door that leads to a patio, but we’re talking specifically about sliding patio doors. Sliding patio doors feature large glazed panels with either one or two moving sections that slide on tracks behind fixed sections. Perfect to connect your home to your garden or as doors to your conservatory, patio doors are available in multiple designs to suit your needs.

Why Choose Sliding Patio Doors?
-
Saves Space
Unlike French doors that open out or inwards, sliding patio doors move one behind the other on a track, saving you valuable garden and living space. Our uPVC and aluminium sliding patio doors are an efficient way of saving space and providing your home with natural light.
-
Energy-Efficient
Our aluminium and uPVC patio sliding doors are an energy efficient solution for your home. Double glazing and thermal breaks in the frames help lock the heat in and keep the cold out. This helps keep your home warm, reducing your energy usage and lowering your bills in the process.
-
Safe and Secure
Our patio doors have high-quality security features as standard. They have a strong multipoint locking system secured with a 3-star rated cylinder lock. The cylinder is anti-bump, anti-drill and has a separate anti-snap guarantee for extra peace of mind.

What is the Difference Between Patio Doors and French Doors?
Patio doors and French doors both provide access to the outdoor areas of your home, but they work in different ways. Patio doors slide open on a track, while French doors are hinged and swing open either inwards or outwards.
Sliding patio doors provide a more space-saving design that can suit a wide range of property styles. French doors generally provide a more traditional and classic look and require more space to be fully opened.

Patio Door FAQs
The cost of patio doors can depend on the configuration you choose, the size of the door, the materials used and, crucially, whether installation is included. Anglian offer made to measure patio doors in aluminium and uPVC, available in various styles and configurations. Because every door is bespoke to your home, every price will be different. Speak to our design team today about your project to get started.
How secure patio doors are can depend on the manufacturer you get them through. If you get your patio doors through a supply only company, they may not include locks or have multiple options which might not all be as secure as one another. Supply and fit companies like Anglian tend to use the same high-quality locks in their doors. Our patio doors come with multi-point locking with a strong 3-star rated cylinder lock.
With regular care and maintenance, a high-quality and professionally fitted sliding patio door made from uPVC can last 20 years or more. Anglian White Knight uPVC patio doors hold the BBA accreditation, which means they can last more than 35 years with regular care. You can expect your aluminium patio doors to last 30 years or more with low level regular maintenance. This is due to their strength and long-lasting finish, powder coated to resist the elements and fading.
When buying a sliding patio door, make sure you have an idea of what the dimensions of your current doors are, as this will have the biggest impact on cost. It’s also worth thinking about what style you’d like, whether that’s French doors or sliding patio doors, both to suit the style of your home as well as work practically with your space. The material you choose is very important too, affecting affordability, energy efficiency and longevity.
The difference between a double door and a patio door is that most ‘double doors’ open outwards, while patio doors slide one behind the other. Double doors that usually open outwards are known as French doors. Patio doors don’t take up any extra internal or external space, as the doors slide neatly behind one another.
