Definitions

  • the present invention relates to a thermal-insulation and drying panel, made of expanded material and designed for thermal insulation of building walls requiring wall moisture to be transported away, as well as a wall thermal-insulation and drying system using i.e. the thermal-insulation and drying panel, and a method of installation of the wall thermal-insulation and drying system.
  • An insulation panel is known from the patent specification PL 204238 B1 , said panel having ventilation slots in form of open ducts, arranged at the panel side which upon installation is contacting the wall of the thermally insulated building.
  • An upper and a lower portion of the thermal-insulation panel according to the patent is formed such that after installing the thermal-insulation panels one above the other, a horizontal ventilation duct is formed between adjacent (vertically) panels, said duct ensuring uniform air distribution from ventilation holes horizontally to individual vertical slots, even if some of the vertical ventilation slots are clogged.
  • the ductwork of ventilation slots are divided into shorter sections by providing, at defined distances, a horizontal diaphragm disabling further air flow in the vertical direction and by arranging vents extending from the outer part of the panel to the horizontal ventilation duct.
  • the ventilation slots which according to invention embodiment of the patent PL 204238 B1 , are 5mm wide, cause unnecessarily high airflow resistance. Furthermore, the horizontal ventilation duct is contacting the vertical slots of the panel located below the horizontal ventilation duct only with a small area (smaller than cross-section of the narrowest section of the ventilation slot) and such narrow slot mouth to the horizontal ventilation duct generates unnecessary airflow resistance (resulting in formation of local whirl zones). Moreover, the horizontal ventilation duct formed between adjacent thermal-insulation panels according to said patent has a relatively small height (of the order few dozens of mm), and therefore during vent installations frequent difficulties occurred in accurate fitting of the installed vent in the middle of the ventilation duct.
  • thermal-insulation and drying panel was developed, generally realising the same functions as the panel described in the patent PL 204238 B1 , however showing no above-mentioned drawbacks, that is thus ensuring airflow at significantly reduced resistance, which in turn has beneficial effect on the wall drying process while reducing heat losses.
  • the thermal-insulation and drying panel according to the present solution also ensures easier and more intuitive installation process, and as well as meets increased requirements for thermal insulation of buildings.
  • the present invention relates to a thermal-insulation and drying panel having a shape composed of two essentially cuboid layers: an inner layer and an outer layer, said layers being offset with respect to each other along two perpendicular edges and constitute an integral element, whereby in a transition area of outer layer into inner layer a displacement region is present, wherein a first side of the inner layer is designed to contact an insulated wall, and the other side of the outer layer which is not in contact with the inner layer, in an assembled state is arranged to face the surroundings of the insulated wall and is designed to be covered with a finishing material, whereby the panel sides other than the first side and the second side constitute side walls of the panel, whereby in the inner layer, at the first side designed to contact the insulated wall, ventilation slots are spaced at regular intervals, and parallel to each other, extending perpendicularly to longer sides of the panel, whereby lower portions of slots are extended so that along the run of ventilation slots within a single thermal-insulation and drying panel ventilation slots comprise, starting from the bottom, an extended
  • first positioning tongues and/or second positioning grooves are provided at the upper surface of the panel positioning elements in form of first positioning tongues and/or second positioning grooves, while at the lower surface of the panel corresponding positioning elements are provided in form of first positioning grooves and/or second positioning tongues, respectively.
  • each ventilation slot connected to the ventilation duct is arcwise, whereby preferably the arc radius is 35 mm.
  • the upper ends of the ventilation slots have rounded side edges, forming roundings, whereby preferably the roundings of side edges of upper ends of ventilation slots have a radius ranging from 5 mm to 20 mm, preferably equal to 10 mm.
  • the side of the outer layer designed to be covered with a finishing material, is covered with an additional layer of material, preferably selected from a group comprising: plaster, ceramic tiles, paint, mineral-based coating or plastic coating.
  • a marking is provided, extending in parallel with the ventilation duct and defining half of the height of the ventilation duct.
  • the ventilation slots have width ranging from 5 mm to 10 mm, preferably equal 7 mm, and in the extended portion are 15 mm wide, whereby centres of adjacent ventilation slots are spaced apart by a distance ranging from 35 mm to 100 mm, preferably equal 50 mm.
  • the total thickness of the panel ranges from 60 mm to 300 mm, in particular from 120 mm to 300 mm, such as 120 mm, 180 mm or 220 mm.
  • the thermal-insulation and drying panel is made of a lightweight material having good thermal-insulation properties, preferably of expanded material, in particular expanded polystyrene or polyurethane.
  • the present invention relates also to a wall thermal-insulation and drying system, comprising:
  • the system further comprises:
  • the present invention relates to a method of installation of a wall thermal-insulation and drying system, comprising the following steps:
  • edges of the thermal-insulation and drying panels fixed to the walls are secured with cuboid corner elements having a square base with a side length equal to the thickness of the thermal-insulation and drying panels.
  • the step e) is followed by a step f): f) covering exhausts of vents (20) with ventilation grilles (21).
  • outer surface thereof, designed to be covered with finishing material is covered, except from the ventilation grilles, with an additional layer of material, in particular selected from a group comprising plaster, plastic, paint and ceramic tiles.
  • Exemplary thermal-insulation and drying panel 1 is a shape composed of a cuboid inner layer 3 which, once installed on the insulated building, is in contact with the building wall, and a cuboid outer layer 2 which, once installed on the insulated building is to be covered with a finishing material.
  • the outer 2 and inner 3 layers are offset to each other along both perpendicular edges and form an integral entity (the thermal-insulation and drying panel 1).
  • the inner layer 3 which is not covered by the outer layer 2, cavities 14 for fastening elements are provided, in particular oval, round or oblong in shape.
  • the thermal-insulation and drying panel 1 is designed to be fixed on the insulated wall in a horizontal position (with a longer edge of the panel 1 in a horizontal orientation).
  • each slot 6 has an extension (an extended portion 7 of ventilation slots), and an upper portion of each slot 6 is a non-extended portion 9, whereby a contracting portion 8 is provided between them.
  • oblong splines a horizontal spline 12 and a vertical spline 13
  • keys a horizontal key 10 and a vertical key 11
  • the horizontal key 10 is provided along the entire length of an upper edge of the outer layer 2, and the vertical key 11 is provided along a right edge of the outer layer 2 (when viewed from the outer layer 2 side of the thermal-insulation and drying panel 1).
  • the horizontal spline 12 extends along a lower edge of the outer layer 2, with extended portions 7 of the ventilation slots 6 extending across the spline, thereby dividing the edge of the horizontal spline 12 into shorter sections, and the vertical spline 13 extends along a left edge of the outer layer 2 (when viewed from outer layer 2 side of the thermal-insulation and drying panel 1).
  • All the splines 12, 13 and keys 10, 11 provided in the thermal-insulation and drying panel 1 have slightly convergent cross-section.
  • the keys 10, 11 and the splines 12, 13 with trapezoid cross-section are provided, however it is clear that other cross-sections of the splines 12, 13 and the keys 10, 11 are possible.
  • the main aim of modification of the cross-section is to facilitate the assembly of adjacent thermal-insulation and drying panels 1 together - even slightly convergent keys/splines facilitate sliding over and locking of one panel above the other.
  • first positioning tongues 16 are provided, and on the lower edge of the outer layer 2 corresponding first positioning grooves 17 are provided.
  • the first positioning tongues 16 and the corresponding first positioning grooves 17 are arranged at regular intervals, corresponding to the intervals between the ventilation slots 6.
  • the first positioning tongues 16 and the first positioning grooves 17 are arranged essentially between the slots, at regular intervals from each side from the adjacent slots 6, but it is not the only possible and preferred configuration.
  • first positioning tongues 16 and the first positioning grooves 17 are provided at regular intervals, but offset to the ventilation slots 6 or simply present directly in the same areas as the ventilation slots 6 (when viewed perpendicularly to the outer surface of the thermal-insulation and drying panel 1).
  • first positioning tongues 16 and the first positioning grooves 17 each time have square cross-section and straight side walls, it is possible to use the first positioning tongues 16 and the first positioning grooves 17 having other shapes, e.g. oval, truncated pyramid, hemisphere, etc.
  • first positioning tongues 16 and the first positioning grooves 17 having transverse dimensions greater than the width of cross section of the ventilation slots 6.
  • the thermal-insulation and drying panels 1 of large thickness in particular with thicker outer layer 2, suitable for thermal insulation of buildings in a harsh climate, e.g. in northern Europe
  • first positioning tongues 16 are located on the upper edge of the outer layer 2 and the first positioning grooves 17 are located on the lower edge of the outer layer 2, it is clear that they can be provided in a reverse configuration or even alternately - along the upper edge, tongue-groove-tongue-groove, etc., and along the lower edge - groove-tongue-groove, etc., respectively.
  • the first positioning grooves 17 and the first positioning tongues 16 have corresponding shapes and are arranged in relation to each other in such a way that during the assembly of the thermal-insulation and drying panels 1 one above the other, they determined such mutual positioning of the panels 1 that the ventilation slots 6 of adjacent panels 1 were positioned facing each other maintaining the vertical continuity of the ventilation slots 6 and ensuring the free air flow along the ventilation slots 6.
  • This ventilation duct 15 has a cross-section with partially contracting sides, which after reaching a certain close-up start to extend in parallel to one another (the cross-section is therefore close to a trapezium with parallel bases, wherein to a shorter base edge a rectangle is joined having a shorter side being equal in length to the shorter base of the trapezium).
  • the ventilation slots 6 provided in the inner layer 3 of the thermal-insulation and drying panel 1 penetrate the horizontal key 10 at least half of the height of the ventilation duct 15, defined by the ventilation duct 15 side walls extending parallel to each other, and preferably are contact the ventilation duct 15 along a section of at least or approximately 0.6 of the height of the ventilation duct 15.
  • this contact area is much greater and thus the air flowing through the ventilation slots 6 to the ventilation duct 15 faces significantly lower flow resistance.
  • vents 20 in addition to providing better airflow from one thermal-insulation and drying panel 1 to another, located above the first one, enables to arrange vents 20 in the thermal-insulation and drying panel 1.
  • the vents 20 are essential due to the reduction of total length of vertical air ducts along the ventilation slots 6. In such situation vents 20 operate in pairs - the vent 20 provided in the lower area of air duct is an inlet (enables ambient air to enter the area between the thermal-insulation and drying panel 1 and the wall), while the vent 20 provided in the upper area of air duct is an outlet (enables the air to flow outside, thereby transporting the moisture away from the wall).
  • vents 20 are placed in some of the thermal-insulation and drying panels 1 already after fixing the thermal-insulation and drying panels 1 to the wall, it is preferable to facilitate installation of these vents 20, in particular so that the vents 20 would allow the air to be effectively removed from underneath the thermal-insulation and drying panel 1. This is achieved by placing the vent 20 axis at the level of the horizontal ventilation duct 15 centre (and more precisely - the centre of the ventilation duct portion with parallel side walls) of a given thermal-insulation and drying panel 1 so that the vent 20 is connected to the horizontal ventilation duct 15 at right angle, which in turn may pose certain difficulty for untrained workers installing the system.
  • a guidance in form of a line located on the front face of the outer layer of the thermal-insulation and drying panel 1, said front face, after installation being parallel to the building wall, whereby this line indicates half of the horizontal ventilation duct height. Arranging the vent at this line minimizes the risk of failure to fit the vent into the horizontal ventilation duct.
  • vents 20 are arranged at right angle to the thermal-insulation and drying panel 1 , in other embodiments it might be preferred to arrange the vents 20 inclined downwards in the direction of the outer side of panel, e.g. at an angle of 2° - 8° in relation to the horizontal, e.g. at an angle of 3°, 4° or 5°. Such slight inclination of the vents 20 allows them to realise an additional function of gravitational drainage of condensate from the inside of the thermal-insulation and drying panel 1 to the environment.
  • vents 20 are necessary of accordingly large geometric dimensions. It has been established that due to heat exchange processes (cooling of building) and moisture drainage (wall drying), the vent 20 should have outer opening of bore (opening net area) between 360 mm 2 and 1500 mm 2 . In case of vents 20 in form of tube sections, a diameter of such vent 20 may be e.g. 50 mm.
  • the vent 20 outer opening is provided with an external grille/net 21 (preferably welded, glued or screwed to the vent 20) - in such case the opening bore is counted as a total area of mesh of such grille/net 21.
  • the thermal-insulation and drying panel 1 according to the invention preferably is made of expanded material, in particular expanded polystyrene or possibly expanded polyurethane.
  • thermal-insulation and drying panels 1 after arranging the thermal-insulation and drying panels 1 in the assembled position at the wall(s) it is preferred to additionally use two types of protective substances - sealing and anti-fungal.
  • Sealing substances such as, e.g. foams, can be used, e.g. to fill voids between the panels 1 or fill in the gaps resulting from mechanical damage (accidental chipping off) of portions of the thermal-insulation and drying panels 1.
  • Anti-fungal substances e.g. in form of sprayed aerosol, can be used after installation of the wall thermal-insulation and drying system, e.g.
  • the wall thermal-insulation and drying system includes:
  • the installation of the wall thermal-insulation and drying system comprises the following steps:
  • corner elements 25 are also used by being arranged in such areas like wall corners, while in contact areas of the thermal-insulation and drying panels 1 with windows/doors, or for finishings in the building roof area, etc.
  • truncated/prefabricated elements from solid expanded polystyrene are preferably used.
  • Said corner elements 25 preferably are shaped as prisms of different bases - square, rectangular, trapezoid or triangular, or as a quarter round, whereby said elements can be solid/monolithic or can comprise hollow spaces (e.g. extending along the entire height of the corner element 25).
  • the corner elements 25 have geometric dimensions adjusted to the thermal-insulation and drying panels 1 being used, i.e. width and thickness of the corner elements 25 is close to or preferably the same as thickness of the thermal-insulation and drying panels 1, and respectively height of the corner elements 25 is close to or preferably the same as the height of the thermal-insulation and drying panels 1.
  • an optional and preferable step is to cover the vents 20 with the ventilation grilles 21 - unless the grilles 21 are pre-integrated (e.g. glued) with the vents 20.
  • the grilles 21 are mounted on the vents 20 preferably by screwing threaded connections or using snap-fit connections. It is also important that, during possible further step of covering the outer surface of already assembled thermal-insulation and drying panels 1 (and corner elements 25 - if present) with a layer of finishing material, e.g. plaster, the vents 20/the ventilation grilles 21 remain unobstructed, and therefore airflow is not disabled.
  • material(s) to be used for covering outer surfaces of already assembled thermal-insulation and drying panels should be selected in accordance with commonly used technologies of external plastering on expanded polystyrene substrates.
  • Group of materials which are particularly preferable to be used includes: plaster, ceramic tiles, paint, mineral-based coating or plastic coating.
