A Beginner’s Guide to the Types of Aluminum Sliding and Folding Windows

Bi-Fold Windows: Opening Up Space

How do they work?

Bi-fold windows consist of multiple panels that are hinged together and designed to fold in on themselves as they slide along a track. When fully opened, the panels stack neatly and compactly to the side of the opening, creating a wide and unobstructed entrance.

Bi-fold windows:

• are a great option for small spaces
• can be fully opened to allow fresh air and natural light to flood into the home
• are aesthetically pleasing
• are available in a range of sizes and configurations, so they can be tailored to your client’s needs

Drawbacks? Bi-folds:

• are relatively expensive
• offer worse air tightness and thermal performance
• require maintenance of the tracks
• have a risk of complaints due to their complicated mechanism
• are better suited for public places and houses located in warmer climates

Lift-and-slide Windows: Ideal for Large Openings

How do they work?

Lift-and-slide windows operate by lifting the sliding panel off its track, which allows it to move effortlessly along the rails. When the panel is lowered back onto the track, it locks into place, creating an airtight seal.

If your client has a large opening in their estate, such as a patio or balcony, introduce them to lift-and-slide sliding windows. They:

• slide open horizontally, allowing for a wide opening and unobstructed views
• achieve excellent thermal performance and can be fitted with microventilation for added airflow
• are easy to operate and maintain
• can have a low or even thresholdless design, making them accessible to people with mobility issues
• are a good solution for investments with not the highest budget

Basic Slide Windows: Budget Solution

How do they work?

Basic slide windows work by sliding horizontally on tracks to open and close. They have one stationary panel and one panel that slides back and forth. When the sliding panel is open, it overlaps with the stationary panel, allowing for ventilation. They are typically operated by pulling or pushing the sliding panel along the tracks.

If you’re looking for a budget-friendly option, basic sliding windows may be the way to go, but remember that they: 

• are a cost-effective option, but their lower quality may result in more maintenance and repairs
• are mostly adequate for mild climates like Arizona or California because of their thermal parameters
• may not meet high aesthetic standards and is therefore not recommended for those with excessive requirements

Panoramic Frameless Sliding Windows: Luxurious Look

How do they work?

Panoramic frameless sliding windows work similarly to lift-and-slide windows, but without visible frames.

Panoramic frameless sliding windows are the premium choice for homeowners who want to maximize their view and have the appropriate budget. They:

• have no visible frames or sashes, creating a sleek and modern look
• provide an unobstructed view of the outdoors, allowing maximum natural light to enter the room and creating a sense of spaciousness
• perform very well thermally
