TECHNICAL ADVICE
How Much do Aluminium Patio Doors Cost?
When designing a new extension, sliding doors will often be one of the main focal points, possibly covering your entire wall with glazing… But how much do they cost?
Many factors affect how much aluminium patio doors cost. You may find a small set of sliders for around £4,500.00 ex VAT, and you can also select a large triple track slider north of £15,000.00 ex VAT.
Cost is certainly a major factor, but always consider the value they will bring to your home, and what’s important to you. Below we have listed the key factors to consider when specifying how much your sliding aluminium patio doors cost.
Factors Influencing Cost
Sightlines
One of the most sought-after features in modern patio doors are slim sightlines. The slimmer the interlocks (the vertical bars between glass panels), the more light you allow into your home. Slimmer profiles are generally more expensive, because they require advanced engineering to minimise frame width yet maintain structural integrity. For example, sightlines can vary from as thin as 20mm to as thick as 117mm, with thinner profiles often commanding a higher price.
Thermal Efficiency
While slim frames are beautiful, they may not always offer the best thermal performance. If energy efficiency is a priority, you might want to consider doors with better u-values, which indicate better insulation performance. Investing in thermally efficient doors can lead to savings on your energy bills in the long run.
Glass Options
The glass you choose is just as important as the frames. Toughened glass is the minimum requirement in sliding doors, but you may wish to opt for:
Laminated Glass
A step up from toughened glass, with great thermal performance and applied wherever safety is a concern.
Solar Control Glass
Ideal for south-facing properties, this glass reduces heat gain.
Laminated Solar Control Glass
Can be specified for the best of both
Design and Aesthetics
Sliding doors can be specified with one, two, three or four doors sliding, and how the doors function is as just significant as their appearance. Specify them with a flush track, for a seamless finish with your internal floor level. Be sure to engage us early in your design process to really perfect this detail.
What to Ask for When Specifying Sliding Doors
When you’re ready to specify how much your aluminium patio doors cost, make sure to discuss the following:
-
Desired sightlines and how they will impact both the look and performance of your doors.
-
The level of thermal efficiency required for your home.
-
Any specific security needs that might necessitate upgraded options.
-
The type of glass that will best suit your home’s orientation and your personal comfort needs.
While aluminium patio doors cost a lot in some cases, understanding the various factors that influence this cost allows you to make an informed decision that balances aesthetics, performance and long-term value. There are certainly cheap options out there, but it really is worth specifying doors that will meet your needs well into the future.
