Advantages of back-vented facades

 

Temperature balance

Even great differences in temperature between summer and winter do not affect a correctly insulated facade. The exterior wall will not be heated up in summer as the solar radiation is reflected to a great extent by the facade material. In winter the wall cannot cool down because of the insulation. Therefore the room air remains pleasantly equable throughout the year. This has economic advantages and advantages for peopl's health.

 

Heat accumulator

The external insulation keeps the heat within the wall and thus uses the storage capacity of the material. This creates a pleasantly equable room air and saves heating costs.

 

Condensate protection

Condensate protection is an essential prerequisite for humidity protection and therefore for the functioning of the insulation. Internal development of condensate which mould as a result will be prevented because the controlled water diffusion is drained off into the ventilating space.

 

Heat bridges

Valuable heating energy is lost especially in older buildings because of insufficiently insulated connecting joint. A continuous insulation bridges these weak spots.

 

Protection against heavy rainfall

Because of physical circumstances there can be no capillary water transport and the rain cannot reach the insulated layers. As a consequence of the permanent possibility of dehumidification through the ventilating space humid layers of insulation can dry up quickly without restricting the efficiency of the insulation.

 

Sound protection

AThe curtain facade also offers effective protection against noise. The majority of the sound waves is reflected by the surface of the shingles and the rest is absorbed by the insulation. Thus a reduction of noise pollution by 7 dB is possible.
