Beautiful ENERGY STAR®-Rated Sliding Windows
Similar to a double hung window but with both sashes sliding horizontally, ecoSmart 365 sliding windows are easy to open with the push of a finger and lift out to make cleaning a breeze. They feature your choice of woodgrain and decorative grille. Customizing your sliding windows is easy when you work with STL Windows Direct!
Our ENERGY STAR®-rated windows can save you up to 35% on your energy bills when you replace all windows in your home. These premium energy-efficient windows are constructed of 100% virgin vinyl and are foam-insulated to deliver unmatched protection against the elements.
Along with a transferable Limited Lifetime Warranty, you also get a lifetime glass breakage warranty with your ecoSmart 365 sliding windows—something the competition simply doesn’t offer!
Designed for High Performance
To ensure maximum performance, we never use mechanical fasteners or screws in our ecoSmart 365 windows. Instead, all windows are constructed with fusion-welded sashes and frames, locking out air and water and making them more durable.
Just a few features of our sliding windows include:
- SmartCore foam insulation.
- ecoCore reinforcement fusion-welded to the frame and sash.
- A roller system to make opening your sliding windows easier than ever.
- Pull rails.
- The ability to lock your window while it’s partially open.
Sliding windows are low-maintenance and a great choice for virtually any room in your home. With triple-paned sealed and insulated glass, your new sliding windows will offer maximum energy efficiency and structural integrity.
