Ventilated Facade

The ventilated facade with an air chamber eliminates the thermal bridges that are created in the slabs as the system is always ahead of them, eliminating thermal dispersion by up to 30%.

Ventilated Facade Systems

Karrat S-7

A system for cladding ventilated facades with direct and hidden fixing.

Hidden clip DGO

DGO is a system based on the punctual anchoring of the cladding pieces by means of clips.

View clip DGV

Exposed anchor that is screwed to the vertical profile and holds the plate with some tabs of the clips.

Chemical DGQ

Fixing system using special adhesive invisible to the eye, ventilated facade panels.

These exterior insulation allows the interior temperatures to remain stable in summer and winter.

In winter, they limit the dangers of condensation and the sensations of low temperature.

The interior temperature does not oscillate sharply despite the interruptions in heating at night or the peaks of the oscillations in the outdoor temperature in winter and summer.

the chimney effect

The ventilated chamber is an exterior insulation system where the chimney effect is created, which is due to the heating of the exterior wall (plate) and causes a variation in the density of the air layer of the intermediate space with respect to ambient air, with the consequent upward movement.

From left to right, we would find what would be the enclosure of the building.

Adhered to the surface of the enclosure, some type of product aimed at the thermal-acoustic insulation of the building.

Next, a free space, a camera and then the exterior plate, which would give the desired appearance to the building.

Summer

A large part of the radiant heat is reflected to the outside, filters into the chamber, activates the chimney effect, so that only a small part of the heat flux is absorbed by the building.
Heat reflection can be increased by using light colors on the wall.

Winter

In cold times, the load-bearing wall acts as an accumulator of interior heat that is more difficult for it to transmit to the exterior due to the insulating layer, therefore, it returns it to the interior.
And also the circulation of air in the chamber helps thermal stabilization.

Elimination of thermal bridges

The correction of thermal bridges makes it possible to significantly reduce global dispersions (even by 30%).
Great energy advantages are obtained. And it eliminates direct radiation with the consequent protection of the building envelope.

Thermal and acoustic comfort

The exterior insulation tends, in summer and winter, to keep the interior temperature stable. In winter it limits the dangers of condensation and the sensations of low temperature.

The indoor temperature does not fluctuate sharply despite heating interruptions at night or spikes in winter outdoor temperature swings.
