Concealed Blinds for Shaped Windows

Triangular, arched, trapezoidal and raking openings are notoriously difficult to shade. Our shaped-window solutions use bottom-up or top-down cellular and roller configurations so the blind body can live along the lowest rail and rise up into the shape.

Configurations

4 Ways to Conceal

Each configuration can be sized to your specific opening. See Technical Drawings and BIM files for exact details.

Bottom-Up Cellular Blinds
01 — Configuration

Bottom-Up Cellular Blinds

Cellular stack sits in a hem-bar box at the sill and rises up into the shape of the window — maximum daylight at the top.

  • Hem bar box concealed in the floor or sill
  • Works with triangles, trapezoids and raking windows
  • Preserves the architectural outline at the top
Bottom-Up Roller Blinds
02 — Configuration

Bottom-Up Roller Blinds

Roller blind version of the same idea — simpler mechanism, slightly less fabric flexibility.

  • Roller cassette concealed at the sill
  • Flat fabric rises into the opening
  • Best for lightly raking triangular glass
Top-Down Cellular Blinds
03 — Configuration

Top-Down Cellular Blinds

Cellular blind concealed at the apex, dropping down into the window — used where floor-level access is impossible.

  • Cellular stack lives at the apex of the shape
  • Blind drops down the sloping edges
  • Selected where a sill-mounted hem bar is impractical
Bottom-Up Cellular in an S Pelmet
04 — Configuration

Bottom-Up Cellular in an S Pelmet

Hem bar box integrated into an S-Series pelmet that sits immediately in front of the shaped window.

  • No floor intervention needed
  • Pelmet front allows plaster-in finishing
  • Ideal for retrofits into shaped windows
