Wind resistance
What is wind resistance?
Wind resistance refers to a frame’s capacity, when subjected to strong pressures and/or depressions such as those caused by the wind, to maintain a permissible deformation, conserve their initial properties and safeguard user safety.
Pressure tests
The Certifying Institute has conducted pressure and wind resistance tests on the various Tecnodoor models, returning the following results:
SCOMAN – class 4 the best possible class
LIMAN STANDARD – class 4 the best possible class
LIMAN HANGAR – class 4 the best possible class
LIMAN ALLU – class 3
LIMOT – class 3
The SCOMAN, LIMAN STANDARD and LIMAN HANGAR doors have been subjected to wind load resistance, measuring the deformations with a pressure of 1100 Pa and checking safety of the sample at a peak load of 1.25 times the pressure of 1100 Pa. The test determined that, for a pressure of 1375 Pa (about 170 Km/h) no opening of the wing panel and no rupture or evident functional impairment was observed. The models reached a wind pressure resistance class of 4, demonstrating the best possible performance in observance of the UNI EN 12424:2001 standard.
The LIMAN ALLU and LIMOT doors have been subjected to the same wind load resistance. The test determined that, for a pressure of 965 Pa (about 143 Km/h) no opening of the wing panel and no rupture or evident functional impairment was observed. The models reached a wind pressure resistance class of 3, respecting the European directives UNI EN 12424:2001.
The following Tecnodoor products are certified for the wind pressure resistance:
