Engineering-led,
by conviction.
Luperal exists because acoustic performance in glazed architecture is too often promised and too rarely proven. We build the systems, run the tests, and publish the chain of evidence.
A systems company that begins at the cross-section.
Luperal designs and supplies precision aluminium systems for glazed partitions, acoustic doors, and interior architecture, for projects across the GCC and internationally from its base in Doha, with presence in Paris and Riyadh.
Every system is engineered as a whole: profile geometry, seals, hardware, and glazing developed together. The Silentium partitions are then validated through independent acoustic and structural testing. The flagship Silentium 100 carries a DAkkS-accredited laboratory result, tested to Rw 52 dB according to ISO 10140-2 and rated according to ISO 717-1.
Design, testing and documentation sit with Luperal. Manufacture, glazing and installation are carried out with partner companies in Qatar. Each party's scope is set out under Who does what.
Who does what.
Luperal is the system owner: it designs the profiles, runs the test programme and issues the documentation. Manufacture, glazing and installation are carried out in Qatar with two partner companies, Spectra Arts and Spectra Glass.

Four convictions, applied to every extrusion.
Engineered, not sourced
Every Luperal profile is developed from first principles: cross-section geometry, wall thicknesses, thermal breaks where needed, and gasket grooves designed for the system they serve. We do not repackage imported catalogues.
Tested as a whole
Laboratory figures are measured on the complete assembly at an accredited laboratory, not extrapolated from glass datasheets. If a configuration has not been tested, we say so.
One system, one logic
Partitions, doors, and glazing are engineered together. Shared depths, shared sightlines, shared finishes, no mismatched frames, no afterthought door details.
Built for the specifier
Section drawings, specification clauses, acoustic reports, and samples, prepared the way consultants submit them. Specification support is an engineering function here, not a sales channel.
What the team actually does.
From profile geometry to laboratory-verified assembly performance, every capability is held under one technical reference.
- Acoustic system engineeringFrom cross-section geometry to laboratory-verified assembly performance.
- Profile developmentCustom extrusions designed in CAD and validated against fabrication constraints.
- Technical documentationSpecification-grade drawings, reports, and fabrication packages.
- Glass system integrationComplete glazed systems coordinated with glass processors under one technical reference.
- Fabricator coordinationShop drawings, site support, and technical clarification through installation.
- Finishing coordinationAnodised, powder coat, and PVD finishes managed across mixed-system projects.
