Mashrabiya screen cassette

Flat cassette cut with a mashrabiya pattern: eight-point stars and lozenges, honeycomb or lattice. Screen, sun shade or façade screen. Adjustable pitch, bar width, frame and gradient; only whole cut-outs are placed, centred on the panel.

Fabrication data

Mashrabiya screen cassette — at 900 × 600 mm in 4 mm ACM, this family unfolds into a 1,004 × 704 mm flat pattern with 8 folds, all grooved from the back: no pass on the coated face. A 1,500 × 3,200 mm sheet holds 6 of them, for 35 % waste.

Manufacturing constraints

  1. The return must exceed the groove width plus half the bend deduction, or the groove eats into the return.
  2. Facet-to-facet folds are grooved with the smallest cutter of the profile, V left open: the angle is held by the geometry. The angle between two facets must not exceed that cutter’s apex angle.
  3. Vertical returns, all tabs flat in the −D plane (rail mounting). The facet-to-return fold is 90° ± slope: below 90°, the 90° cutter is left open and the return is held by the riveted tab; above 90° (facet descending towards the edge), a wider cutter (60° nominal = 120° apex) or the machine profile’s overfold tolerance is needed.
  4. Every raised vertex requires a V-slit to the edge (a flat sheet has 360°, the relief less). Near the vertex the slit is narrower than the contour tool: it is cut along its axis and the tool bites each facet by up to Ø/2.
  5. Tabs are shortened at every corner and every kink of the edge so they never collide behind the panel: by (return + 2 mm), and more on a sharp corner, where the bisector must be cleared (tab width ÷ tan(angle/2)). An edge too short gets no tab.
  6. Bars between two cut-outs keep at least 3 times the sheet thickness: thinner, they bend in handling and flutter in the wind once installed.
  7. Every cut-out must let the contour tool in: star points are rounded to its radius, and a cut-out narrower than the tool cannot be machined. The gradient shrinks cut-outs: its smallest size is bounded accordingly.
  8. Only whole cut-outs are placed, inside the solid frame. If the pitch exceeds the panel minus the frame, none fits: reduce the pitch or the frame.
