Module comprised of fiber mats

A method of producing an insulation system comprised of a plurality of modules, each module comprised of a plurality of fiber mats, at least one fastening element and at least one transverse rod, for insulating surfaces selected from the group of roofs, walls, ceilings, and floors, said method comprising the steps of:

• a) arranging a plurality of fiber mats adjacent to one another to form a rectangular body;
• b) providing at least one fastening element comprising a perforated plate with a plurality of bores distributed randomly and closely adjacent to one another over a surface of said plate;
• c) connecting said at least one fastening element to a surface to be insulated;
• d) positioning said rectangular body on said at least one fastening element such that said perforated plate extends into said rectangular body parallel to said adjacent fiber mats;
• e) pushing at least one transverse rod into said rectangular body so as to extend transverse to said adjacent fiber mats and parallel to the surface to be insulated;
• f) securing said at least one transverse rod at said at least one fastening element by pushing said at least one transverse rod into one of said bores to thereby connect said rectangular body to the surface to be insulated;
• and
• g) repeating steps a) to f).
