FACADES THERMAL BRIDGE REHABILITATION

Thermal bridges on the facades

Thermal bridges are considered zones building envelope in which a variation of uniformity of the construction, either by changing the thickness of the cladding, of the materials used, penetration of building elements with different conductivity evidence, etc. , Which necessarily results in a lower thermal resistance compared to other enclosures.

The existence of thermal bridges in the faade of the Communities of owners increases the likelihood of production of surface condensation or moisture condensation, especially in winter or cold weather.


Moisture condensation is the result of retention of water vapor in the capillary walls, walls or coatings by varying temperature inside from the outside. It is caused by the temperature difference between warm and cold outside inside. This contrast causes the surface condensation of excess ambient water vapor.

The moisture condensation caused by thermal bridges, are usually manifested as fungal colonies (dark spots) or in the form of droplets (as if the wall perspire). Inside the buildings, the humidity is located in ceilings and floors (at the height of fronts wrought) and concrete pillars in contact with the external cladding of the facades of neighboring communities.

Rehabilitation of facades of communities through the sate system (thermal insulation from the outside) seems to be the most suitable to eliminate almost all of the existing facades of neighboring communities thermal bridges and is currently the most widely used in the rehabilitation of existing buildings.
