The architectureof quiet.
Engineered aluminium systems for acoustic glass partitions, doors, and sliding walls. Laboratory-tested partitions, documented for specification.
Luperal engineers the interface between aluminium, glass, and silence.
Luperal designs and supplies aluminium systems for acoustic glass partitions, doors, and sliding walls for offices and commercial interiors across the GCC. The flagship partition is laboratory tested to Rw 52 dB.
Profiles, gaskets, glazing, and hardware are developed as one system. The Silentium partitions are laboratory tested as complete assemblies and documented at the level formal submission demands, not the level brochures promise.
Three families. One discipline.
Every Luperal system shares the same profile logic, gasket engineering, and finish range. Choose by what the space demands.

Laboratory-tested acoustic performance
Silentium 100: Rw 52 dB.
C −1 · Ctr −4 · measured on the full Silentium 100 assembly
Laboratory tested
Not a glass rating. Not a simulation. The complete partition, profiles, gaskets, glazing, and junctions, measured in a DAkkS-accredited laboratory to ISO 10140-2 and rated to ISO 717-1.
Silentium Alto, the asymmetric build-up on the same structure, is laboratory tested at Rw 51 dB.

10 ways to shape light
Clear to ceramic-printed, acoustic laminated to switchable smart glass.
Glass options
Aluminium profiles, removable glazing and replaceable gaskets, dry-assembled so a partition can be reconfigured instead of demolished. Responsible specification
