Decorative screens, lattices, and grills are usually light weight elements used as partitions. Most are designed as single space unit panels and can sometimes be used singly and free-standing. Others can be continuous assemblies fashioned to any size up to the bay width of the structure. Unless employing them as a design feature, most will not use vertical Secondary frame members to support them, relying on their own finished structure elements, either approximating 50mm stud size or employing two fitted panel sizes to accommodate corners.
The simplest form for these employs a semi-rigid panel 10mm thick and 2420mm high which simply flexes to pop into place between upper and lower framing profile slots, just like pop-in panels. An optional spacer with 10mm slots fits over the vertical edges and the same finishing strips employed with pop-in panels may be used. This form is useful for panels made of uniform materials and machine-cut into the desired screen/lattice pattern. This is also useful for light variations of the stationary Japanese shoji or fusama paneling. Pop-in screens may also use a facade casement which provides a framing detail that pops into the intermediate space used by finishing strips and locks in with the same thin alloy tabs
Many screen/lattice panels will feature some kind of integral casement frame, usually of joined wood, in their design which gives them both greater rigidity and thickness. Fashioned to 50mm thick, this allows for either friction fit alone or the use of countersunk screws and T-nuts along top and bottom.
Grills are made up of individual slats or rods which stand independently on the framing or on a casement frame which is attached to the frame on T-nuts. The simplest use simple 10mm tabs or pins and pop into place on the frame, optionally using T-nuts as in-slot spacers. They may also attach to a decorative casement frame in the same way, the frame mounting screws sometimes concealed by a slat or rod. Such frames most common for those using angled slats, which use routed fitted slots for the slats. Diagonal grills employ end tabs that feature an integral spacer and are stacked diagonally against each other, working inward from opposing upper and lower corners. A final center slat with an arrow-shaped tab then holds the assembly in place. The slats are mounted to avoid tension plug bolts where the center slat is placed.
Stretched fabric screens will usually employ a nautical aesthetic and employ sail-like attachment using eyelets and decorative toggle-clamps bolted to the surrounding frame on T-nuts or cable tensioning. Interlaced or crossing wire or cable screens mount similarly, using turnbuckles and swages that attach directly to T-nuts, possibly through perimeter decorative cover strips concealing the slots.
The full range of possible screen, lattice, and grills designs is endless and beyond the scope of this document, but most will employ attachment methods similar to the above.
