Definitions

• the invention relates to a method for insulating building facades by attaching several, 2 to 30 cm thick panels made of a hard foam with a density of 10 to 100 g / 1 on the facade and then applying a firmly adhering plaster layer on the foam panels.
• Hard foam plastics e.g. based on polystyrene particle foam
• the panels are provided with a firmly adhering plaster. Due to the shrinkage and / or thermal contraction of the rigid foam sheets, strong tensile forces are formed in both main directions in the plane of the board when deformation is prevented in the plane of the board. These are transferred to the cover layer, which is firmly connected to the surface of the panel, where they lead to stresses that occur concentrated over the butt joints of the panels.
• the invention was based on the object of largely reducing the forces exerted by the foam sheets as a result of shrinkage and thermal change in length on the overall composite and in particular on the cover layer above the butt joints, without, however, the other properties, especially the thermal insulation and the pressure rigidity perpendicular to Plate level are negatively affected.
• a rollable thermal insulation sheet which consists of an insulating layer made of foamed plastic material, which is glued to a cover sheet.
• the insulating layer has, on the side opposite the cover sheet, transverse incisions, by which the rollability of the thermal insulation sheet is made possible.
• plates are used which are provided at least on the side facing the plaster layer with two sets of parallel cuts perpendicular to the plane of the plate, the depth of the cuts being greater than half the plate thickness
• the distances between the incisions are between 3 and 30 cm and the two coulters are orthogonal or at an angle of ⁇ 75 ° to each other.
• the stiffness and strength of the foam sheets perpendicular to the sheet plane is not changed by the cut grid.
• the deposition time required for foam sheets can be reduced to a few days or can be eliminated entirely.
• Preferred hard foams are those based on polystyrene, in particular flame-retardant polystyrene particle foam.
• polystyrene foam in particular flame-retardant polystyrene particle foam.
• polystyrene foam there are also extruded polystyrene foam, polyvinyl chloride foam and hard-set Suitable polyurethane foam, also thermosetting foams based on condensation products of urea, melamine or phenols with formaldehyde.
• the thickness of the foams is between 10 and 100 g / l, preferably between 10 and 50 g / l.
• the thickness of the plates can be between 2 and 30, preferably between 3 and 20 cm.
• the plates are preferably provided with the cutting grids on only one side, specifically on the side which is connected to the cover layer in the installed state.
• the expedients are expediently perpendicular to the plane of the plate, but an oblique cut, for example up to an angle of 75 ° to the plane of the plate, should not be ruled out the individual incisions are 3 to 30 cm, preferably 5 to 20 cm, the depth of the incisions is greater than half the panel thickness, and if the incision depth - as in the foam panels described in FR-A-2 142 759 - is less than half the panel thickness , then the occurrence of tension in the bond with the plaster layer cannot be avoided slots are determined by the type of tool. It can be between 0 and 3 mm, preferably between 0 and 1 mm; If the slots are even wider, the insulating effect of the insulation board is impaired and cold bridges can occur.
• the two batches of cuts are preferably orthogonal; however, they can also run at an angle of 75 ° to one another.
• the slotted foam panels can be folded around the edges like conventional insulation. According to the invention, they are provided with a plaster layer, optionally reinforced.
• the thermal insulation layer according to the invention is glued onto a 24 cm thick sand-lime brick masonry using a conventional construction adhesive made from a synthetic resin dispersion with cement additive.
• the insulation layer consists of 8 cm thick, 50 cm wide and 100 cm long sheets of flame-retardant foam polystyrene with a density of 15 g / l.
• the plates are provided with two orthogonal panels with 6 cm deep incisions that are 10 cm apart (see drawing).
• a base plaster with a thickness of 5 mm is applied to the insulation layer, in the middle of which a glass fiber mesh fabric is embedded as reinforcement. After the base plaster has hardened, a synthetic resin-bonded rubbing plaster with a thickness of 3 mm is applied.
• An outer facade insulation is obtained in which, in contrast to conventionally constructed insulation based on untreated foam panels, no stress peaks occur over the butt joints of the panels, so that the risk of cracks in the outer layers is largely eliminated.
