What is a sliding window?
Sliding window replacement in Upstate SC is one of the smartest investments you can make for your home’s comfort and curb appeal. Sliding windows are a great addition to any home and allow you to maximize ventilation throughout every season. Also known as gliding windows, pocket sliding windows, or horizontal sliding windows, they operate horizontally with one sash sliding into a pocket across the other providing ample open space to the outside. The sashes glide on brass rollers for smooth, effortless operation every time.
Many modern homes and ranch-style homes are designed for horizontal sliding windows. They look great, complement a wide range of architectural styles, and are easy to maintain. The sashes lift out of the pocket for simple cleaning without needing a ladder. Once you’re done, put the sashes back in the locked position for security; they cannot be removed when locked in place.


Double the options with a Two-Lite Slider
You’ll love the versatility of the Two-Lite Slider. It allows you to move the sashes in either direction, giving you ventilation on either side of the equal-sized sashes. If you’ve been searching for replacement sliding windows that offer flexibility and a clean modern look, this is an excellent starting point.
Three-Lite Sliders
Our Three-Lite Slider gives you the best of both worlds: one stationary section and two sliding sections that can be operated from either side of the window. The fixed center can be up to two times the width of the operative sashes, or you can choose equal-sized sashes for a more balanced appearance. These custom sliding windows are built to fit your exact opening and your specific ventilation needs.
