VENTILATED FAÇADES AND DOUBLE WALLS

In the essence of the functioning of a double wall is the contribution of the air gap to the evaporation and drainage of humidity coming from the outside by infiltration or capillarity, or even by condensation of the vapor in transit from the inside to the outside.

The frequent presence of humidity in the air gap is therefore a key aspect to take into account when choosing the thermal insulation for this application.

The insensitivity to water, zero capillarity and high resistance to the passage of vapor allow the ifoam ® Paredes (walls) rigid extruded polystyrene foam to maintain their thermal insulation characteristics over the entire life of the building, regardless of any moisture in the air gap, and also reduce the possibility of condensation without the need for additional vapour barriers.

The ifoam® Paredes (walls) insulation panels have been designed to make application extremely easy. While its length of 2.6m allows the height of the air gap to be easily reached with a single panel at the top, the male-female fit allows interlocking between the panels and a self-supporting performance of the thermal insulation panel.

In addition to being the ideal thermal insulation solution for double walls, ifoam® Paredes (walls) panels also offer an easy, self-supporting and durable solution for insulating ventilated façades or for the thermal rehabilitation of sloped roofs with a discontinuous structure

THERMAL BRIDGE TREATMENT

The existence of thermal bridges in the building environment has not only the disadvantage of additional thermal losses in these areas, but also and mainly the effect of deterioration of the construction elements in these areas, through the appearance of surface and interstitial humidity caused by condensation.

The most significant examples of thermal bridging zones are slab, beam, and column fronts in double-walled buildings, which see the thermal insulation of the air gap interrupted in these concrete elements.

The ifoam® eco panels have both sides with roughness designed to allow good adhesion of mortars, cementitious adhesives and other cementitious materials. Combined with its insensitivity to water, high mechanical strength and ease of cutting, ifoam® eco is an efficient thermal correction solution, whether applied to the inside or the outside of concrete façade elements, and then allows plaster, render or other final finish to be applied.

EXTERIOR INSULATED FAÇADES ETICS SYSTEMS

Whether in new construction or in refurbishment of buildings, the placement of continuous thermal insulation on the outer face of the façade allows a considerable reduction of thermal bridges, which has contributed to the increase of popularity of these systems, whether curtain wall or ventilated façade type, or in the form of ETICS system (External Thermal Insulation Composite Systems).

The rough surface on both faces, as well as the high mechanical strength, allowing perfect adhesion of mortars and adhesive cements, added to the total insensitivity to water and zero capillarity make the ifoam ® eco extruded polystyrene panels a particularly suitable solution for ETICS systems.

For the same reasons, ifoam® eco is the most suitable solution for the thermal insulation of walls and ceilings from the inside, allowing the direct application of stucco or plaster.
