Benefits:
1.- Acoustics:
It is measured in decibels (dB) and represents the ability to prevent noise from passing through the door.
2.- Air:
Air permeability is measured in classes ranging from 0 to 4 and indicating the ability to prevent air from passing.
3.- Thermal:
It is indicated by a U (measured in W / m2oC) and represents the ability to prevent heat exchange between two environments. The lower it is
the U value, the lower the energy passage between both faces and therefore better the insulating capabilities of the product.
4.- Water:
Water tightness is measured in classes ranging from 0 to 9 and indicating the ability to prevent water from passing.
5.- Wind:
Wind resistance is measured in classes ranging from 0 to 5, which indicate the mechanical resistance of the security door to gusts of wind.
