Horizontal Sliding Windows Defined

Horizontal sliding windows are a type of sash window similar to single or double-hung windows. Rather than opening vertically, horizontal sliding windows open horizontally by sliding the sash from left to right or vice versa. Single horizontal sliding windows have one operable sash while double horizontal sliding windows have two operable sashes.

The Milgard Ultra Series fiberglass windows are top of the line when it comes to window technology. Fiberglass is an eco-friendly window material that provides the highest energy-efficiency levels available. Fiberglass is made primarily of silica sand, an abundant natural resource. Glass is made primarily of sand. Thus the frame and glass expand and contract at roughly the same rate while remaining resistant to swelling, rotting, and warping, allowing for a longer lifespan.

Features and Benefits:

  • Extremely durable with an expected lifespan of nearly 80 years.
  • Strong frame material allows for large custom sizes
  • Paintable frames that homeowners can update to match current home color trends
  • Low expansion/contraction rate through 100-degree temperature changes means less glass and caulking failure over time
  •  An Energy Star package tailored to the Seattle region for optimal energy efficiency.
  •  Custom colors, hardware, and glass options to match any home design.
