Definitions

• the technical problem represents an implementation of facades, produced on the basis of moisture-rich surfaces (construction moisture, capillary rise moisture on periphery walls, ground water or rain water or other types of moisture).
• the technical problem deals with how the moisture runs through the whole facade surface into the surrounding area.
• the facade is not merely a protection or a building decoration; it simultaneously provides a pleasant room climate, reduces energy consumption and therefore protects the environment and reduces the emissions of the C0 2 equivalent. It is hence a fundamental life investment, which provides savings on a daily basis.
• the contact facade systems are effected by applying the visible roughcast and paintwork finishings directly on thermal insulation without any intermediate air layer whatsoever and neither any other layer.
• Thermal insulation panels are glued, often with special anchors, to the periphery wall, usually made from brick, reinforced concrete, foam concrete and similar materials. From the constructional and physical point of view the solution is not optimal, as excellent water-tightness and vapour permeability can hardly be expected from the finishing layers.
• the contact insulation facade is a system of external thermal building envelope, in which case thermal insulation is glued or mechanically fastened directly on the external wall; upon thermal insulation we apply basic and finishing decorative roughcasting, giving monolithic properties to the facade without any contact of fissures, joints or other, similar problems.
• these facades cut heating costs and simultaneously offer elegant, rich-in-design surfaces, providing expressive potential to forms and colours; they also combine the latest experience and know-how in technical development, construction engineering, mechanics, construction physics and chemistry.
• the solution includes deep notches into the panel side facing the wall. Following the implementing solution, the notches predominantly run in one direction or principally into several directions, preferably two, which mutually run in approximately perpendicular directions.
• the notches herein have two favourable effects.
• the first one is vapour transmission under the panel surface, consequently balancing vapour diffusion and preventing the situation of vapour passing through more intensely at one point and less intensely at other.
• the second favourable effect is adapting the panel to uneven spots in the surface. Insulation panels made of polystyrene, polyurethane or other insulation materials make it possible for the panel to locally force its way on the spot facing the surface, whereas on the other side (facing the opposite direction) it actually remains smooth-faced.
• the panels are optionally facing the surroundings, which do not only provide diffusion, but in some cases convection of vapour from the surface and intense drying.
• the notches are as deep as a 15% average thickness of the facade panels, on a primary basis more, comparatively exceeding 40%, but not exceeding 85% of thickness and on a primary basis not exceeding 75% of thickness.
• the facade panel can be used as an alternative for all current systems of contact insulation facades on the basis of expanded polystyrene (EPS) or STYROFOAM, as the surface of a new panel on the side of the facade end is completely the same as current panels, whereas the reverse side of the panel contains additional ventilation channels running vertically and horizontally to the surface of the wall, providing ideal vapour pressure equalization. Due to deep notches and channels the moisture transmission coefficient ' ⁇ ' is reduced (from 35 to less than 18, naturally depending on the size, depth and arrangement of the ventilation channels).
• EPS expanded polystyrene
• STYROFOAM expanded polystyrene
• Equalizing vapour pressure and therefore free vapour transmission from the structure into the surrounding area is therefore facilitated.
• the structures can be dried out without retaining or even accumulating water vapour. Because the notches are placed at the wall side, it is possible to equalize vapour pressure behind the facade, despite the fact that facade adhesive is applied to that particular spot. Equalization is possible via continuous deep ventilation notches (channels) on the reverse side of the innovative insulation panel. Such facade is considerably more resilient to damage, caused by local condensation of water vapour.
• This system provides water vapour equalization behind facade layers and consequently makes it much easier for the condensed moisture to exit through the entire surface of the facade and enter the surrounding area, due to equalization of internal vapour pressure with external vapour pressure.
• the part of the structure with increased moisture content can be effectively dried by diffusely open contact facade.
• It provides the implementation of the facade on sensitive surfaces and freshly-made surfaces; it can be used during rehabilitation procedures and, because of the capillary moisture in the walls it facilitates the transmission of rain water or ground water; it can be used even in cases of damaged wiring installation or damaged surfaces and on surfaces from foamed concrete or lightweight concrete, perlite or in other similar cases.
• Vapour permeability ( ⁇ ) of the panel following this invention, is less than 18 and depends on the size, depth and arrangement of the ventilation channels, whereas this value in commonly used panels is 30 to 35.
• Figure 1 shows a facade panel, representing the panel front not facing the surface.
• the notches, facing the surface can be clearly seen.
• Figure 2 shows a facade panel revealing the panel front, lying against the surface, particularly the external wall.
• the notches, which run in several directions following the implemented case, are clearly seen.
• Both figures show arrows, denoting directions of vapour transmission down the notches which function as narrow channels (regardless of their potential capillary characteristics because of the small transversal section).
