Space
The sliding operation is useful where outward clearance is limited.
WINDOORLY / WINDOW STYLES
Slider Windows
Slider windows open horizontally along a track, providing ventilation without a sash swinging into the room or outdoors.
Getting to Know the Style
About Slider Windows
A slider window has one or more sashes that move horizontally along a track. Because the sash stays within the window footprint, it is a straightforward option for openings where an outward-swinging window would be inconvenient.
Finding the Right Fit
Where they work well
Consider sliders beside patios, walkways and decks, or in wide openings where a horizontal layout complements the room. The sash needs to be within comfortable reach and have enough unobstructed track to move. Depending on the design, only part of the window opens at a time.

What to consider
The right choice depends on your home, the opening and how you use the space.
Operation
A sash moves along a track to open and close the window.
Maintenance
Keeping the track clear helps the sash move smoothly.
Make It Your Own
Design and product choices
Consider these details as you compare options for your home.
Opening configuration
Ask which sash moves, the opening direction and how much ventilation area the selected configuration provides.
Glass and frames
Compare frame materials, finishes and glazing options for your priorities and climate.
Screens and locks
Check screen access and the position of the lock and handles before selecting the window.
Planning Your Project
Assessment and installation
Accurate measurement and a level opening are important to smooth operation. We check the existing window and surrounding frame, then explain the proposed installation, finishing and any repairs needed before providing a quote.
Looking After Your Windows
Care and maintenance
Remove dirt from the track and drainage openings according to the manufacturer’s instructions. Clean the frame and glass, and have sticking, damaged rollers or a faulty lock assessed rather than forcing the sash.
FAQ
Frequently asked questions about slider windows
Do slider windows project outside?
The sash slides within the window frame, so it does not swing outward like a casement or awning window.
Does the whole window open?
Usually only the operable portion opens. The available opening depends on the configuration and product.
Why is my slider hard to move?
Debris, worn components or alignment may be involved. Clean the track as directed and arrange an assessment if the problem continues.
Can a slider replace another window style?
Often it can, subject to the opening, applicable requirements and the selected product. The existing conditions need to be measured and assessed.
