inertia of the profiles
To make an objective comparison with conventional stick systems, there are 3 aspects to be considered
The rigidity of the profiles, or the I-value for equal weight per meter
The ability to transfer vertical loads from the exterior to the mullion
The mechanics of the transom/mullion connection
Knowing that H60
is a composite insulated profile, assembled by a polyamide thermal break, instead of 2 or 3 profiles (mullion, pressure plate and cap) kept together by screws
the exterior shell of the H60 mullion has a very large wall thickness
the I-value of H60 mullion, for the same weight/m of profiles, will always be a multiple compared to a conventional system.
As the area moment of inertia relates to the height of a profile to the third power, it is clear that the Fassada H60 system embraces the full potential of the height, whereas in traditional systems the pressure plate has no contribution to the mechanical performance.
In contrast to traditional stick systems, the Fassada H60 comprises a rigid thermal break connecting the exterior profile to the interior one, which allows to transfer significant vertical loads. By consequence, installing specific elements such as louvers or even a double skin is possible.
Regarding the mechanics of the transom/mullion connection, see the corresponding topic, never a more performant, more logic connection has been realized in stick system technology.
These three aspects result in not just outstanding performance of the profiles, but also for the integral mechanics of the hybrid system.
