Surface condensations inside the house

Moisture inside a house is one of the most common problems, and it is not always caused by water filtration from the outside. Most of the time, moisture due to condensation is generated on the inner side of the enclosures due to poor insulation, which causes cooling and makes the air, which is in contact with the inner side of the wall, cool down abruptly below dew temperature. Likewise, another possible cause is not properly aired rooms, which leads to an excessive level of vapour in the environment that, when exceeding 45%, causes steam to condense.

A home with condensation problems is very easy to identify: fungi and mould in corners and walls; windows and mirrors with fogged glass; damaged furniture and other objects, and even hazardous electrical installations.

How to avoid surface condensation

The solution for getting rid of surface condensation is to increase the temperature inside the house: the higher the temperature inside the house, the lower the possibility of surface condensation. How is this done? It mainly depends on the location of the house, but it can be done by means of a heating system or by adequately insulating the areas most sensitive to the thermal bridge.

The most common thermal bridges are found in: areas where the structure meets the enclosure, slab edges or pillars; slabs on porches and open spaces; the contours of hollow spaces; roller blind boxes.

In these areas, when the weather conditions are unfavourable (such as abundant cold and/or rain), the lack of insulation allows the temperature inside the enclosure to reach indoor dew temperature, causing the appearance of mould stains.

Another variable involved in the formation of condensation is the relative environmental humidity, or the amount of atmospheric water vapour. It is difficult to maintain this amount constant because modern technology and lifestyles have increased the formation of water vapour: kitchen equipment, greater use of toilets in showers or bathrooms, etc., and, on the other hand, the sealing of woodwork has greatly increased.

The result of this condensation is moisture in the insulation layer, which gradually reduces its insulating capacity. In some cases, the water not soaked up by the insulation is displaced to the bottom, producing a moisture stain inside the building at the height of the slabs.

Ventilated aluminium facades

Ventilated aluminium facades are an ideal building system to beautify the building envelope and provide greater insulation to the interior. Modern architecture projects are choosing this resource to add aesthetic value to their buildings.

The ventilated aluminium facade serves as a thermal cushion, saving 30% more energy than other building solutions.

It is a building system that requires little maintenance. It basically consists of an external layer, an insulating layer, and an internal layer. The structure is highly resistant to thermal shocks despite its low weight.
