Sliding Glass Doors vs. Folding Doors: The Ultimate Guide to Choosing the Best Patio Door in 2025
When it comes to enhancing your home's outdoor access, sliding glass doors and folding doors are two of the most popular options. Both provide seamless indoor-outdoor transitions, maximize natural light, and add aesthetic appeal. However, they come with different functionalities, benefits, and price points.
If you're looking to upgrade your patio or outdoor space, this comprehensive guide will break down the differences between sliding glass doors and folding doors, their costs, pros and cons, and how to choose the best option for your home.
What Are Sliding Glass Doors?
A sliding glass door (also called a patio sliding door) consists of large glass panels that glide horizontally along a track. Unlike traditional hinged doors, sliding doors don’t require additional space for swinging, making them ideal for areas with limited room.
Benefits of Sliding Glass Doors
- Space-Saving Design – Because they slide along a track instead of swinging open, they don’t require extra clearance.
- Energy Efficiency – Modern sliding doors come with double-pane glass, low-E coatings, and thermal insulation for energy savings.
- Smooth Operation – High-quality roller systems make opening and closing effortless.
- Affordable Option – Compared to folding doors, sliding glass doors are generally more budget-friendly.
Average Cost of Sliding Glass Doors in 2025
The cost of sliding glass doors varies based on size, material, and glass type:
| Size (Width x Height in Inches) | Material | Average Cost (Installed) |
|---|---|---|
| 60 x 80 | Vinyl | $1,000 - $1,800 |
| 72 x 80 | Aluminum | $1,500 - $2,500 |
| 96 x 82 | Fiberglass | $2,000 - $3,500 |
| 108 x 80 | Wood | $3,000 - $5,500 |
What Are Folding Doors?
Folding doors (also known as bi-fold doors or accordion doors) consist of multiple glass panels that fold together like an accordion. They provide a wide, unobstructed opening, making them a great choice for maximizing airflow and creating an indoor-outdoor living experience.
Benefits of Folding Doors
- Wider Openings – Unlike sliding doors, which only open halfway, bi-fold doors open up to 100% of the space.
- Luxurious Aesthetic – These doors add a high-end, modern touch to any home.
- Customizable Configurations – You can choose 2-panel, 3-panel, or even 6-panel designs depending on the space available.
Average Cost of Folding Doors in 2025
Folding doors are typically more expensive than sliding glass doors due to their complex design:
| Size (Width x Height in Inches) | Material | Average Cost (Installed) |
|---|---|---|
| 72 x 80 | Vinyl | $2,500 - $4,500 |
| 96 x 82 | Aluminum | $4,000 - $7,500 |
| 120 x 80 | Fiberglass | $5,500 - $9,000 |
| 144 x 96 | Wood | $8,000 - $15,000 |
