The durability of the FoamLime system, continuously exposed to outdoor conditions, depends, above all, on the humidity degree. To properly protect both the system and the underlying materials it is necessary that the set be hydrophobic.
In order to guarantee the durability of Foamlime, Grupo Ibercal has added EPH-DRY Technology to all the components of the system.
EPH-DRY is an innovation by Grupo Ibercal. It is a hydrophobic compound made up from silicon nano-particles which react together creating a three-dimensional reticule which does not block pores and allows water vapour diffusion, thus creating a waterproof effect; water drops do not penetrate facades covered with FoamLime but slip down them, sweeping dust and impurities; they self-clean. Moreover, dirt does not seep into the covering because it disappears along with water drops. The result is that the facade remains clean longer.
Excellent anti-dampness protection
The prefect water repellence of the FoamLime system is evidenced by water-drops formation. The organic functional groups of the silicon nano-particles present in EPH-DRY enable pores and capillaries to repel water permanently. FoamLime thus avoids water penetration without sacrificing breathability.
Dry facades prevent fungus and algae development
The average time a facade remains dry per year is longer when the mortar that covers it has been treated with EPH-DRY. Water drops also wipe fungus and algae spores off, leaving a gleaming facade behind.
Besides, the fungicidal and bactericidal effect intrinsic of lime protects facades against strong degradation due to thick vegetation, high air humidity or big groundwater pressures.
Every effective covering must prevent the penetration of humidity without being an obstacle for breathability. There are always zones in buildings where dampness tends to accumulate under the covering. The only effective and long-lasting way to preserve the facade is to ensure a quick exit for this dampness. This is an especially important requirement in modern External Thermal Insulation Composite Systems (ETICS) because humidity penetration reduces energy-saving potential dramatically in buildings.
