Protection against atmospheric agents

Protection against atmospheric agents

An enclosure should guarantee the maximum possible protection against atmospheric agents. This means it should restrict the filtration of air, be completely watertight and be able to resist the power of wind.

To ensure this, all of our window and door systems are tested in our laboratories in order to meet the current regulations.

AIR PERMEABILITY
Air permeability is the property of a closed window to prevent air from passing through when subject to differential pressures (wind force).

The applicable test measures the air flow (m³/h) that passes through the test sample due to the application of test pressure.

Air permeability Classification

CLASE 1 < CLASE 2 < CLASE 3 < CLASE 4

Test standard: EN 1026:2000

Classification: EN 12207:2000

This data shows us the quantity of air that passes through a window over time and area. From these results, we can say that the class 4 window is three times more impermeable than the Class 3, which is three times more impermeable than the Class 2 window, which is approximately two times more impermeable than the class 1 window when tested at 100 Pa.

WATER-TIGHTNESS

Water-tightness is defined as the capacity of a closed window to prevent water from passing through.

The applicable test consists of the constant spraying of water whilst applying increasing levels of pressure until water passes through the test sample.

WIND RESISTANCE

The test of wind resistant verifies that, under the effect of increase and decrease in pressure, the complete window has an acceptable level of deformation, maintains its properties and guarantees its safe use.

The test consists of the application of positive and negative pressures to determine the relative deflection and its resistance to deterioration
