Sliding Doors Features & Benefits

Transform Your Home

With the help of I Want Window and Doors, we can transform your home with our incredible aluminium sliding doors that stand the test of time. Enjoy a more open space that is filled with natural light for many years to come. 

As soon as you install our aluminium sliding doors, you will experience numerous benefits. Open up your doors in the warmer months for a well ventilated space and enjoy a warm and cosy space that you can relax in in the colder months.

Energy Efficient

Our aluminium sliding doors offer extremely low U-values that ensure the heat you produce is retained for a cosy and comfortable space you can enjoy no matter the weather. 

Our large glass panes are double glazed, which works to slow down heat transfer and keep the cold breeze outside. Aluminium is highly energy efficient as it features thermal break technology, which uses low conductive materials to retain the heat.

Bespoke To You

All our sliding doors are made to measure to fit all kinds of property sizes. Depending on the size of your home will determine how many panels your doors will need. 

We offer a fully bespoke design with an unlimited colour range from RAL. You can design your doors to suit your home’s style and character. Opt for our wood grain finish if you are looking for a more traditional design.


Aluminium is highly durable and corrosion resistant, which means that your doors are protected against harsh weather conditions and strong forces whilst remaining in top condition. 

Our wide glass panes are tested to withstand strong winds and storms to keep you protected all year round.

Highly Secure

Secure locking systems that give you peace of mind that your home is safe at all times. Whilst large glass panels typically are seen to be less secure, double glazing is exceptionally durable and virtually indestructible. 

Our aluminium sliding doors from Cortizo are made with incredibly secure materials and come with advanced security systems, making them impossible to break into.

Slimline Profiles

Aluminium sliding doors feature slimline frames that allow for high levels of sunlight to flood your home, creating a brighter and lighter atmosphere. The large glass panes and slimline profiles open up your space and allow for undisturbed views so you can make the most of your beautiful garden scenery.
