Bifold doors—also known as folding doors—have become a popular choice for homeowners and builders looking to maximize space without sacrificing design or functionality. With a panel system that folds neatly onto itself, bifold doors allow for wide, seamless openings, connecting indoor and outdoor areas, or serving as stylish interior dividers.
In this article, we cover everything you need to know before choosing bifold doors, and how PRL Glass can help you find the ideal solution for your project.
Thinking About Installing Bifold Doors? Here’s What You Should Know
Bifold doors, or accordion doors, are a growing trend for those seeking to open up spaces without visual barriers. However, there are a few key considerations to keep in mind before installing them. And we break them down for you.
Types and Materials
Bifold doors can be installed both indoors and outdoors. They’re perfect for:
- Connecting living rooms with gardens or patios
- Dividing interior spaces without building permanent walls
- Enhancing natural light and offering a sleek, minimalist design
These systems are made with weather-resistant, yet elegant materials. After all, they’re a visible design element of your home. Common frame materials include:
- Aluminum: Lightweight, durable, and modern-looking. An excellent value-for-money option
- Wood: Brings warmth and natural aesthetics
- uPVC: A budget-friendly, low-maintenance alternative
Transparent panels are typically made from glass, although low-end systems may use plastic, which is not recommended due to reduced durability and clarity.
✅ At PRL Glass, we design high-performance bifold systems using tempered glass and aluminum, perfect for residential and commercial applications alike.
Space Requirements
Before choosing a bifold system, it’s crucial to evaluate your available space. Unlike sliding or standard swing doors, bifold doors require room to fold and stack.
- Opening Space: Panels need clearance to fold and stack along the wall without obstructions
- Track Length: These systems run on top, bottom, or dual tracks. Large openings may require multiple tracks
- Custom Sizes: At PRL, we manufacture custom bifold doors tailored to the dimensions and demands of your project
Our team will measure and assess your space to ensure a perfect fit.
Operation and Key Features
The folding mechanism is what defines bifold doors and it’s essential to understand how it works:
- Opening System: Panels fold neatly to one side, saving space
- Handles and Locks: These must be secure, durable, and tested for long-term use
There are two main support systems:
- Top-Hung Systems: These are known for smoother, more reliable performances, especially in modern designs
- Bottom-Rolling Systems: Weight is supported by the bottom track—suitable for specific structural needs
Security Features
A multi-point locking system and reinforced hardware are recommended—and come built into PRL’s bifold systems.
Additionally, specialized glass can offer enhanced protection. For example, laminated or bullet-resistant glass. Or our new Battle doors, that provide added security against external threats.
Energy Efficiency
Modern bifold doors offer more than just aesthetics. They can also boost your building’s thermal performance. While most come with quality glass, high-end systems go a step further.
One standout solution is our thermally broken system. It drastically reduces HVAC costs by keeping indoor temperatures stable and blocking excessive heat or cold for long-lasting comfort.
Installation and Maintenance
Proper installation ensures smooth operation and long-term durability:
- Professional Installation: Due to their complexity, bifold systems should always be installed by trained professionals
- Routine Maintenance: Regularly lubricate hardware, clean frames, and inspect tracks to keep everything in top shape
