Aluminium VS uPVC

Choosing between aluminium patio doors and uPVC patio doors is an important decision. Each system has its own range of benefits and unique offerings, but there are a few key differences that make them both stand out. 

At Patio Sliders, our Decalu 163 aluminium patio doors are incredibly secure and have polyamide thermal breaks to ensure their energy efficiency remains high. Meanwhile, our Slider24+ uPVC system is number 1 for colour and is available in a wide array of woodgrain foils to match older style homes. 

Aluminium patio doors are almost unbeatable for reusability and recyclability. They are durable and long lasting while remaining lightweight and easy to operate. However, uPVC patio doors are also lightweight and highly secure and new advancements in recycling facilities allow for large amounts of uPVC to be reused as well.

At Patio Sliders by Deceuninck, we provide the best in sustainability and have invested in our state of the art recycling facility. This allows us to recycle our aluminium patio doors and uPVC patio doors, leading to a more sustainable and eco-friendly environment for all.

Energy Efficiency

All of our patio doors are exceedingly energy efficient. The polyamide thermal break within our aluminium patio doors combines with the double or triple glazing to reach U-values as low as 1.0 W/m2K for the double glazing version and 0.4 W/m2K for the triple glazing version, respectively.

Meanwhile, our uPVC patio doors are also A-rated for energy efficiency. Both systems can keep homes warm, cosy, and comfortable. Come rain or shine; patio doors can retain ambient heat within a home, letting homeowners rely less on their gas or electricity to warm their homes in the colder months. Increasing a home's energy efficiency can also have the added benefit of reducing a home's carbon footprint, as well as reducing energy consumption and bills. 

Security and Safety

At Patio Sliders, we take the security of our products seriously. Patio doors are typically used as back entrances to a home from a garden, patio, or deck. Because of this, ensuring that they can keep out unwanted visitors or intense weather like wind or rain is integral to their design.

Our Slider24+ and Decalu 163 lift and slide patio sliding doors have been rigorously tested so that they meet PAS 24 requirements. PAS 24 is a standardised series of security and safety tests that measure the security performance of windows and doors throughout the UK. The Slider24+ patio doors are also approved by the Neighbourhood Watch and are Document Q and M compliant.

Additionally, both of our patio sliding doors come with a comprehensive 10 year manufacturer’s guarantee for total peace of mind.


There is a massive variety of colours for patio doors when you choose Patio Sliders by Deceuninck. The Heritage Colour Collection has 26 colourways available from stock for our uPVC patio doors. From Chartwell green to classic cream, golden oak, or anthracite grey, our uPVC patio doors can come in almost any popular hue.

The colours used on the uPVC patio doors are built to be robust and can resist scratching or fading after exposure to harsh weather for long periods of time. The woodgrain foils can be a fantastic choice for those working on heritage property projects or for homeowners who want to enhance their security and energy efficiency without compromising the traditional look and feel of their home.

For total colour cohesion, our uPVC patio doors are available with matching ancillaries, trims, and accessories for every one of our colours.

Slim Sightlines

Patio sliding doors are mainly chosen for their ability to provide a broad entrance to a home. Our sliding doors are made with slim sightlines at the forefront of their design, and the uPVC and aluminium systems are both capable of offering slimmer sightlines than old timber systems with no compromise on security or durability.

Slimmer sightlines mean more space is left for our bespoke double glazing, leading to a more thermally efficient set of doors that also provide gorgeous, uninterrupted views. These unobstructed panes can flood homes with natural light, leading to less reliance on electricity for lighting on sunny days. 

Additionally, we’re pleased to offer our patio sliding doors with a low threshold, making them safer and easier for those with wheelchairs and pushchairs. 

Low Maintenance

All the sliding doors we manufacture are easy to maintain thanks to the modern materials that they are made of. Aluminium sliding doors and uPVC sliding doors can each be cleaned with nothing more than just a soapy sponge and warm water. The slim frames and profiles lead to fewer nooks and crannies for dirt or dust to accumulate, and unlike traditional timber, they never need to be varnished, sanded, or repainted.

Aluminium sliding doors are also capable of keeping their shape without warping, and the metal liners and rollers can ensure smooth opening and closing performance without risk of rusting or hitching.

Patio Door Costs & Price Guide

Patio door prices can vary depending on a large number of factors, such as the patio door size, number of panes, material, colour, hardware options, and more. This doesn’t even begin to incorporate things outside the doors themselves, like delivery or installation.
