    25 30 536 686 extent by means of the vertical aeration batten mounted behind the horizontal nail batten (Trä Guiden).
    SUMMARY OF THE PRESENT INVENTION The inventor has realized that the aeration behind an outer panel of wood can be increased if the panel boards are formed with aeration grooves on the inside of the panel board which run over the entire length of the panel board so that the upper and lower edges of the aeration rafter are open. The purpose of the aeration grooves is that moisture that accumulates behind the panel is to be removed by air flowing through the grooves so that the moisture is transported away from the wall by convection. The inventor has discovered that if the aeration grooves have a depth and / or width which is less than 10 mm, the air flow in the grooves will be almost non-existent. The inventor has therefore realized that the aeration grooves must have a depth and a width of at least 10 mm in order to achieve a sufficiently good air flow. Furthermore, the inventor has realized that in order to meet the strength requirements, panel boards with such aeration grooves must be at least 25 mm thick.
    A first aspect of the present invention therefore relates to an outer panel panel board characterized in that the panel board thickness is at least 25 mm and that the inside of the panel board has at least one aeration groove extending over the entire length of the panel board and where both the aeration groove depth and the aeration groove width are at least 10 mm. corners are rounded or bevelled.
    A second aspect of the invention relates to a wall element for a building where the outside of the wall element is covered by tongue-and-groove panel where the tongue-and-groove panel has tongue-and-groove panel boards where the panel boards are at least 25 mm thick and the backboards have at least one aeration groove and the width of the aeration grooves is at least 10 mm and where the corners of the aeration grooves are rounded or bevelled. A third aspect of the invention relates to the use of pane board or wall elements according to one of the embodiments of the first or second aspect in the construction of a building.
    A fourth aspect of the invention relates to a method for increasing the aeration in an outer panel, characterized in that the backs of the panel boards are provided with aeration grooves with a width and depth of at least 10 mm and where the corners of the aeration grooves are rounded or bevelled. Brief Description of the Figures Figure 1 shows a pane board according to the present invention.
    Figure 2 shows a wall element according to the present invention.
    Detailed Description of the Invention The present invention aims to increase aeration and remove moisture behind an outer panel. The problem is solved by providing the backs of the panel boards with ventilation grooves with a width and depth of at least 10 mm. There are already panel boards with grooved backs on the market. The grooves are often shallow and narrow and the depth of the grooves and the width of the grooves are usually less than 5 mm. The purpose of this type of groove is to prevent the panel boards from bulging. Since grooves with a width and depth below 10 mm do not appear to affect the convection, this type of panel boards, unlike the panel boards according to the present invention, does not solve the problem of increasing the aeration and removing moisture behind an outer panel.
    One aspect of the present invention relates to a panel board for outer panel characterized in that the thickness of the panel board is at least 25 mm and that the inside of the panel board has at least one aeration groove running over the entire length of the panel board and where both the depth of the aeration groove and the aeration groove width rounded or beveled. A necessary feature of the present invention is that the aeration groove is open at both ends of the panel board so that the aeration groove of a panel board in an outer wall is in direct contact with the surrounding outdoor air.
    Temperature differences and wind will then contribute to air flowing through the aeration grooves in the panel boards, which leads to moisture being transported out from the inside of the panel by convection.
    However, the inventor has discovered that a prerequisite for a sufficiently good convection is that the depth and width of the aeration grooves is at least 10 mm. A further improvement of the convection has been demonstrated if the depth and / or width of the grooves is increased to 15 mm or to 20 mm. In one embodiment, therefore, the depth and / or width of the aeration grooves is at least 15 mm, such as at least 20 mm. In one embodiment, the width of the aeration groove is between 10 and 50 mm, such as between 15 and 40 mm, such as between 20 and 30 mm. In one embodiment, the depth of the aeration groove is 10-20 mm, preferably 10-15 mm, such as 12-15 mm.
    The inventor has also realized that the aeration grooves adversely affect the strength of the panel. For example, the inventor has realized that a panel board having a thickness of 22 mm, which is a common standard thickness for exterior panel boards, does not exhibit the strength properties desired for exterior panel boards, if vent grooves of the present invention are milled into the boards. The inventor has realized that the thickness of the panel board must be at least 25 mm in order to achieve desired strength properties. If the aeration groove is made deeper than 10 mm, it is advantageous to have a thicker board. Since deeper aeration grooves are advantageous because they increase the convection, it is also desirable that the thickness of the panel board exceeds 25 mm. In one embodiment, therefore, the thickness of the panel board is at least 26 mm, such as at least 27 mm, such as at least 28 mm, such as at least 29 mm, such as at least 30 mm. However, it is often advantageous that the thickness of the panel board does not exceed 35 mm. Therefore, in a preferred embodiment, the thickness of the panel board is between 25 and 35 mm such as between 26 and 35 mm such as between 27 and 35 mm, so between 15 and 25 mm such as between 28 and 35 mm such as between 29 and 35 mm, such as between 30 and 35 mm. In a particularly preferred embodiment, the thickness of the panel board is 27-32 mm.
    In order to maximize the convection without drastically deteriorating the strength, the inventor has realized that it is advantageous for the width of the aeration barrier to be greater than the depth of the aeration grooves. In one embodiment, therefore, the width of the aeration groove exceeds the depth of the aeration groove. In a particularly preferred embodiment, the width of the aeration groove is between 15 and 25 mm and the depth of the aeration groove is between 10 and 15 mm.
    The inventor has further realized that the convection and removal of moisture can be further increased if the aeration grooves have rounded or bevelled corners.
    The corners of the ventilation grooves are therefore rounded or bevelled. Another advantage of rounded and bevelled corners is that the pouring strength of the panel board increases compared to if the corners are sharp.
    Since the panel boards are intended to be used as a panel for an exterior wall in buildings such as houses, garages, machine halls and the like, it is preferred that the length of the panel boards be adapted to such lengths as are usually used for exterior panels in such buildings. In one embodiment, therefore, the length of the panel board is between 1.8 and 6 meters, preferably between 2 and 5 meters, such as between 2 and 4.5 meters. Since the panel boards are intended to be used as a panel for an exterior wall in buildings such as houses, garages, machine halls and the like, it is preferred that the width of the panel boards be adapted to such dimensions as are usually used for exterior panels in such buildings. In one embodiment, therefore, the width of the panel board is between 45 and 250 mm, preferably between 90 and 170 mm, preferably between 115 and 150 mm. For economic reasons, it is most advantageous to use panel boards of any of the standard dimensions 95 mm, 120 mm or 145 mm. In a particularly preferred embodiment, therefore, the width of the panel boards is 95 mm, 120 mm or 145 mm. In one embodiment, the width of the panel boards is 92-98 mm, 117-123 mm or 142-148 mm. The panel board of the present invention has at least one aeration groove. According to a preferred embodiment, the panel board has 1-3 aeration grooves. According to one embodiment, the panel board has 1 aeration groove. According to one embodiment, the panel board has 2 aeration grooves. According to one embodiment, the panel board has 3 aeration rafters.
    The need for aeration is greater in some types of panel than in others. For example, the need for aeration of a lid panel is less because aeration there takes place through the cavity between the bottom boards. Spontaneous panels are relatively rainproof and therefore provide good protection against penetrating moisture. A disadvantage of tongue-and-groove panels compared with, for example, cover panels is that the aeration behind the panel can be worse because tongue-and-groove panels are normally in one layer. Thus, no cavity is formed between the boards where aeration can take place. Therefore, the present invention is particularly suitable for tongue-and-groove panel boards. In a particularly preferred embodiment, therefore, the panel board is a spontaneous panel board. By spontaneous panel is meant that the panel has a cut-out part or a folding, and a protruding part which fits into the cut-out part or in the folding on a similar adjacent board. All types of such tongue-and-groove panels and tongue-and-groove panel boards are suitable for the present invention.
    According to one embodiment, the tongue-and-groove panel board is of the double-phase or single-phase type. According to one embodiment, the panel board is of the type spontaneous groove panel with straight edges, spontaneous groove panel with bevelled edges, folded groove panel with bevelled edges, spontaneous barrier panel with straight edges. According to one embodiment, the tongue-and-groove panel board is of z-profile.
    In cases where the width of the aeration groove is not constant over the entire depth of the aeration groove, the term "aeration groove width" refers to the average width of the groove over the entire depth. In a preferred embodiment, however, the width of the aeration groove is at least 10 mm, preferably at least 15 mm such as at least 20 mm over at least 5 mm, preferably at least 10 mm, preferably at least 15 mm, preferably at least 20 mm of the air groove depth. If the edges of the air groove are bevelled or rounded, the width of the groove at the bottom of the groove may in some cases be less than 10 mm. In one embodiment, therefore, the width of the air groove is narrowest at the bottom of the groove. In one embodiment, the width of the groove is not less than 5 mm in any position in the groove. In one embodiment, the width of the groove is almost constant over the entire depth of the groove and no part of the groove width is less than 10 mm. In one embodiment, the width of the groove varies by a maximum of 5 mm over the depth of the groove, preferably by a maximum of 3 mm. The walls of the groove should be relatively smooth so that moisture does not get stuck in irregularities in the aeration grooves. In a preferred embodiment, therefore, the surfaces of the walls of the aeration groove are smooth. In one embodiment, the surface flatness of the walls is in the range +/- 1 mm above the depth of the air groove.
    The panel board according to the present invention can be made of any wooden material. The most common wood in the construction of houses, garages and other constructions is spruce in Sweden. In a preferred embodiment, therefore, the panel board is of spruce.
    The inventor has realized that sheet piled panels are particularly suitable in building modules, such as wall elements, since two wall elements can be brought together without a joint forming where moisture can penetrate. A second aspect of the present invention therefore relates to a wall element for a building where the outside of the wall element is covered by sheet piling where the sheet piling has sheet piling boards according to any of the above described embodiments of the first aspect of the invention. In one embodiment, the height of the wall element is between 1.8 and 6 meters, preferably between 2 and 5 meters, such as between 2 and 4.5 meters. In one embodiment, the width of wall elements is between 60-600 cm, preferably between 80 and 200 cm. In one embodiment, the wall element contains a wind-stopping layer with a thickness between 0.05 and 1 mm, preferably between 0.1 and 0.5 mm. In one embodiment, the wind-stopping layer is a windbreak fabric such as, for example, windboard.
    A third aspect of the invention relates to the use of a panel board or wall element according to any of the embodiments of the first or second aspect in the construction of a building. According to a preferred embodiment, the panel board is used for the outer panel on the outer wall of the building. According to one embodiment, the building is a house, garage, machine hall, carport, shed, stable, barn and / or storage building. In one embodiment, the building's building area is between 15 and 300 square meters and the building's height between 2 and 6 meters.
    Building area refers to the area that a building occupies on the land.
    A fourth aspect of the invention relates to a method for increasing the aeration in an outer panel, wherein the method comprises that aeration grooves with a width and depth of at least 10 mm are made in panel boards and where the corners of the aeration grooves are rounded or bevelled. The embodiments of the first, second and third aspects also apply to the fourth aspect.
