Principle of ventilated cladding system



Advantages of ventilated facades

1. Insulation during winter time

Insulation, fixed on the outside wall, allows a continous and low thermal bridge construction.  The insulatation material is adequate for all insulation requirements.

2. Insulation during summer time

Heat accumulation - heat is mostly prevented because of the ventilation between insulation and facade.  As the outside wall heats up slowly, the outside fluctuation of temperature has mostly no influence of the inside room temperature.

3. Rain protection, open joints

Airflow that exists behind the outside wall reduces penetrating water, so the insulation remains in function.

4. Sound insulation

More than 15 dB improvement compared to solid walls.

5. Humid protection

The condensation water zone is outside the wall.

6. Water steam diffusion

By means of building physics, the ventilated facade has the most safety function, with diffusion open heat insulation simply ideal.  No need for a vapour barrier.

7. In winter, heat accumulation in the wall will equalise temperature

More wall thickness means more heat accumulation capacity for a room.  In case of short interruptions to internal heating facilities, or if capacity is reduced, the temperature equalization is made.

8. Building protection

The outside walls are protected against fluctuation of temperature due to the insulation.  Wall-loads are by-passed.  Wall stays dry, therefore no further corrosion failure.
