What Influences the Price of Folding Doors? 

Many people mention that prices for folding patio doors range from $800 to $1200, but this changes a lot.  

But don’t worry, we are going to explain all the factors included in the price so you can know how much it costs to install them.   

Factor 1: Aperture Size  

First you need to consider the size of what you need. The larger the opening, the greater the number of panels needed and, therefore, the higher the cost.  

For example, standard systems typically have:  

• Heights from 7′ to 10′  

• Widths from 9′ to over 18′ wide  

• Configurations ranging from 2 to more than 20 panels, reaching up to 20 meters wide.  

But, this is one hundred percent custom, as they can be much smaller or even have somewhat odd angles to account for in the lengths.  

In addition, some configurations include a daily–use door for convenience without the need to open the entire system, so it’s taken as a different panel.   

Factor 2: Frame Material 

The frame of a door (which can have different thicknesses, depending on the project) is an essential part of the construction and therefore an important part of the final price.  

The material has a significant influence on the final price:  

•  Aluminum: The most economical, light and resistant option, and undoubtedly the favorite for homes and businesses. There are thermally broken options for greater energy efficiency and weather resistance.  

• Fiberglass: A mid-range alternative with good insulation. 

• Natural wood: More expensive but with great aesthetic value  

• Steel: Not as common due to weight, but some projects require it.  

 ✅ Usually the combination of glass and aluminum is the most economical and functional choice for most home and business projects. 

Factor 3: Glass Types and Finishes 

Glass defines not only aesthetics, but also thermal insulation and safety. You can choose between: 

• Double or triple glazing for better insulation  

• Tempered or laminated glass for safety and security  

• Decorative or UV-treated glass 

👉  Glass type and custom options can increase the cost by 10% to 30% depending on the type of glass or finish selected. 

Factor 4: Additional Customizations 

As we mentioned, if you need non-standard sizes or configurations, the price will go up. Custom doors are ideal for unique architectural projects, but they require more production time and a higher investment.   

Usually, this cost is considered from the beginning of the project and customizations are offered by dedicated companies such as PRL Glass & Aluminum.
