Definitions

• the present invention is relating to a structural wall according to the introductory part of claim 1.
• Such walls are often vented on the inner surface of the base plate such that the insulating ability of the base plate is not especially utilized. Further, the base plate is not fire retardant involving such walls that are not approved for buildings having more than two floors.
• a double supplementary insulation is achieved. Firstly, this is consisting of the insulating ability in the added insulating material and, secondly, by keeping the insulating ability of the base plate intact as no air circulation worth mentioning occurs on the inside thereof. Moreover, the fire retardant effect of the insulating material involves that building heights having more two floors can be allowed.
• the drawing illustrates a horizontal view through a self-supporting frame work wall 1 having insulation 2.
• the wall is having fastening devices 3, here in the form of laths 4, preferably with a dimension of 50x50 mm.
• the wall 1 is shown without any kind of venting slits in the drawing, the skilled person understands that the wall can be equipped with such venting slits. If so, these can be situated in a distance of 4 to 5 meters, or only at the top or bottom of the wall, or exclusively in the form of edges around doors and windows, or in any other suitable fashion in the wall.
• base plates 5 made from wood composite material, preferably of the type bearing the trade designation Fasec and mainly comprising of polyurethane mixed with wood wool.
• the plates 5 can preferably have a thickness of 10-15 mm but this can be varied if needed.
• a insulating material 6 in the form of rock wool mats 7 externally being provided with drainage facilities 8 for moisture, here in the form of vertical drainage slits 9.
• the insulating material 6 has preferably the same thickness as the laths 4 and can on the outer surface thereof be glued on the base plate 5.
• the base plates 5 is equipped with a layer of plaster 10, preferably a cement-modified polymer plaster.
• a suitable primer is added to ensure sufficient attachment for the plaster 10.
• the plaster provides for a jointless facade being very resistant to the weather and wind.
• the thickness of the plaster can approximately be 10 mm.
• the illustrated wall construction is having a windproof and diffusion-open cardboard 11 externally on the insulation 2 of the frame work wall 1, and internally the wall 1 is having a 0,2 mm polyethylene sheet 12 and a 13 mm plasterboard 13.
• the invention can also be used for other wall types that the one being illustrated and described.
• the invention is especially suitable for external supplementary insulation of concrete and brick walls. Tests of such walls in cold regions have proven that the relative humidity remains far below 100 % on all points within the wall, thereby avoiding condensation. Such supplementary insulation will also be favourable in warm regions as it is reducing storage of heat within the wall during the day and, thus, is contributing to maintain the indoor temperature at a lower level.
• the insulating material can be any suitable material other than rock wool mats and that the drainage facilities thereof do not need to be vertical slits or channels. An irregular or uneven outer side of the material can be useful, or the drainage facility can inherently be within the construction of the material. Moreover, the thickness of the insulating material can be varied after requirements.
