Certificates
We do not declare our doors’ properties on paper — we verify them with tests in accredited laboratories in the Czech Republic and abroad. Below are the main parameters our constructions meet.
Fire resistance
Fire- and smoke-rated construction up to class EI45 and up to 3 metres high — also combined with security and acoustics.
Security class
Security doors certified in class RC3 — a reinforced construction that resists forced entry.
Acoustic reduction
Soundproof doors rated Rw 32, 38 and 42 dB. We guarantee the acoustics when the full leaf-and-frame set is supplied.
Durability — cycling
Fire doors with the integrated Geze Boxer closer passed the cycling test in the top class C5 — 200,000 cycles with no damage to the construction.
How we test
We run tests and certification with our own development staff and together with accredited laboratories. A number of the tests — fire, smoke-tightness, security and acoustic — were carried out within innovation projects co-financed by the European Union.
Certificates, test reports and declarations of performance are provided for a specific project on request. Technical and commercial documents are in the Downloads section.
