They’re perfect for homeowners seeking enhanced airflow, energy efficiency, and long-lasting performance without compromising on convenience or aesthetic appeal.

Sliding window trim enhances both the appearance and performance of a window by providing a clean, finished edge around the frame. It covers gaps between the window and wall, helping to seal out air, water, and pests. Interior trim, such as casing and sill, adds decorative detail and complements interior design, while exterior trim—like brickmould or PVC boards—offers weather resistance and protects against moisture damage. Available in wood, PVC, or composite materials, sliding window trim can be customized in various profiles and colors to suit different architectural styles. It completes the look while improving energy efficiency and durability of the window system.
