Sheer Shades

Sheer shades combine soft fabric vanes with sheer panels in a variety of styles. In one style, the vanes “float” between two sheer panels while in another, the vanes attach to a sheer backing

Woven Shades

Artistically woven from natural materials, woven wood shades infuse organic style, texture and warmth into a room. They complement a wide variety of aesthetics, making them a gorgeous solution for controlling natural light

Custom Roman Shades

The soft or crisp folds of Roman shades give them a timeless appeal, making them a popular choice for any aesthetic, with endless design possibilities. When lowered, Roman shade fabric lays flat; as you raise the shade, the fabric gradually rolls up

Somfy and Rollease Acmeda Motorization

Benefits of Motorization
  • Added Convenience—easily control shades with a button press, tap on your mobile device, automatically, or even with your voice.

  • Increased Privacy—schedule shades to automatically close whenever you want.

  • Better Energy Efficiency—schedule shades to raise and lower to keep interiors warmer or cooler, depending on the season.

  • Enhanced Security—give your home a lived-in look while you’re away by scheduling shades to automatically raise and lower at set times.

  • Safer for Children—because smart shades lack lift cords, they’re a safer option than shades with exposed cords.
