The present invention relates to a heat-insulating-material mat (10) in particular for building construction, which is formed from layers (1, 2, 3, 4, etc.) which are arranged loosely one above the other and are made of insulating materials which fuse together exclusively under the heat of a standard flame of a fire test conducted in accordance with standard DIN EN ISO 11925-2 and are held together by means of at least one seam (31, 32, 33) which is configured in undulating form in the longitudinal direction (X) and/or transverse direction (Y) of the mat (10) and in the case of which at least one thread (20, 21, 22) is guided through the layers (1, 2, 3, 4, etc.), wherein the undulating form of the seam (31, 32, 33) is dimensioned such that, constantly changing in position in relation to the local surface area of the standard flame, it moves out of the local flame-treatment surface area. A method for producing heat-insulating-material mats (10) making use of a multi-needle sewing machine is also claimed. The heat-insulating-material mat (10) according to the invention, which can be supplied in a variant which is closed to diffusion and in a variant which is open to diffusion, is suitable for insulating static objects such as roofs, walls/facades or floors and also for lining, for example, drivers' cabs, caravans and other means of transport. |
