Sliding Windows Defined
Sliding windows, sometimes called gliding or horizontal slider windows, are a type of sash window similar to single or double-hung windows. Rather than opening vertically, sliding windows open horizontally by sliding the sash from left to right or vice versa. Single sliding windows have one stationary sash and one operable sash, while double sliding windows have two operable sashes.

Fiberglass Sliding Windows
Milgard C700 Series Fiberglass Sliding Windows
The Milgard C700 Series sliding window harnesses the resilience of fiberglass in a smooth, panel-gliding design built for easy operation and lasting performance. Fiberglass is among the toughest frame materials available, engineered from silica sand to flex at nearly the same rate as glass, keeping seals intact, drafts out, and weatherproofing performing for the long haul.

Quieter interiors when you need it. Available laminated glass options cut down on outside noise, offering a calmer indoor environment for homes near highways, flight paths, or busy streets.
A design that fits many home styles. Six frame color options, coordinated hardware finishes, and a clean contemporary profile pair well with everything from classic Craftsman architecture to modern new construction.

Horizontal Sliding Window FAQs
What’s the difference between vinyl and fiberglass sliding windows?
Vinyl sliding windows are made from PVC and are known for being affordable and low-maintenance. Fiberglass sliding windows are made from glass fibers and resin, offering superior strength, durability, and thermal performance. Fiberglass also resists warping and expansion better than vinyl in extreme temperatures.
Do sliding windows require additional framing?
In most replacement situations, sliding windows fit into the existing frame opening without additional framing. However, if the existing frame is damaged or if you’re changing the window size, new framing may be needed.
Are sliding windows safe?
Yes, sliding windows are safe. They come with locking mechanisms that secure the window in place. Many models also offer optional keyed locks and ventilation limiters for added security.
How do I determine the size of the replacement window I need?
Measure the width and height of the existing window opening from the inside of the frame. Take measurements at multiple points and use the smallest dimension. A professional installer will take precise measurements during an in-home consultation.
How long does it take to install horizontal sliding windows?
A typical horizontal sliding window replacement takes about 30 to 60 minutes per window, depending on the size and condition of the existing frame. Most homes can be completed in a single day.
How do sliding windows compare to other window designs regarding energy efficiency?
Sliding windows offer good energy efficiency, especially when paired with double or triple-pane glass and low-E coatings. While they may not match the airtight seal of casement windows, modern sliding windows with quality weatherstripping provide excellent insulation.
How do sliding windows compare to single-hung and double-hung windows?
Sliding windows move horizontally, while hung windows move vertically. Sliding windows are generally easier to operate and better suited for wider openings. Hung windows work better in taller, narrower spaces and may offer slightly better air sealing.
Can sliding windows be used in a bay or bow window design?
Yes, sliding windows can be incorporated into bay or bow window configurations. They are often used as the operable side windows flanking a fixed center picture window.
Do you offer new construction windows?
Yes, we offer both replacement and new construction windows. Contact us to discuss your project needs and we’ll recommend the best solution.
