A sliding window (also called a glider) opens horizontally along a track instead of lifting up. With no crank and no sash to raise, they’re the easiest window to operate and a natural fit for wide openings, bedrooms, and contemporary homes. Sliders offer expansive glass and clean sightlines, and modern units run on smooth rollers with quality weatherstripping to keep drafts out.

Sliding Window Replacement FAQs
Are sliding windows good for egress?
Often yes — their wide opening can satisfy egress width requirements for a basement or bedroom. We confirm the clear-opening dimensions meet code before installing.
How do I keep sliding window tracks working smoothly?
Vacuum the track and wipe it clean a couple of times a year, then apply a dry silicone lubricant. Keeping debris out of the track is the main maintenance task.
