       2 . Arrangement according to  claim 1 , wherein an insulating material of the insulating material sheet is compressible and flexible. 
   
   
       3 . Arrangement according to  claim 1 , wherein an insulating material is chosen from the group comprising a polyester nonwover fibre, glass wool and mineral wool. 
   
   
       4 . Arrangement according to  claim 1 , wherein the insulating material sheet has a thickness of more than 1 cm. 
   
   
       5 . Arrangement according to  claim 1 , wherein the counter-battens are fixedly connected, to rafters, with the composite sheet being placed in between, and in that the composite sheet is compressed in a region of the counter-battens. 
   
   
       6 . Arrangement according to  claim 1 , wherein a thermal conductivity of the composite sheet in a non-compressed state is between 0.025 to 0.05 W/(m·K), and, in a compressed state, between 0.02 and 0.045 W/(m·K). 
   
   
       7 . Arrangement according to  claim 1 , wherein a length of the composite sheet is greater than 3 m. 
   
   
       8 . Arrangement according to  claim 1 , wherein a width of the composite sheet is greater than b  50  cm. 
   
   
       9 . Arrangement according to  claim 1 , wherein a weight of the composite sheet is greater than 300 g/m 2 . 
   
   
       10 . Arrangement according to  claim 1 , wherein a height of the counter-battens is greater than a thickness of the composite sheet. 
   
   
       11 . Arrangement according to  claim 1 , wherein a sealing tape is provided between at least one counter-batten and the underlay sheet. 
   
   
       12 . Arrangement according to  claim 1 , wherein a sealing tape has a thickness of more than 1 mm. 
   
   
       13 . Arrangement according to  claim 1 , wherein a sealing tape has an adhesive coating on at least one side. 
   
   
       14 . Arrangement according to  claim 1 , wherein the underlay sheet is watertight and diffusion-open. 
   
   
       15 . Arrangement according to  claim 1 , wherein the underlay sheet comprises a nonwoven layer with an external watertight and diffusion-open coating. 
   
   
       16 . Arrangement according to  claim 1 , wherein the underlay sheet is provided, on its upper side, with an embossed grid pattern. 
   
   
       17 . Arrangement according to  claim 1 , wherein a width of the underlay sheet is greater than a width of the insulating material sheet such that a projecting longitudinal edge is provided, and such that, an adhesive edge is provided on an underside of at least one longitudinal edge projecting beyond the insulating material sheet for a purpose of connecting adjacent composite sheets in a windtight manner. 
   
   
       18 . Arrangement according to  claim 1 , wherein a plurality of composite sheets laid parallel to one another and parallel to eaves are provided. 
   
   
       19 . Arrangement according to  claim 1 , wherein the insulating material sheets of adjacent composite sheets butt tightly and substantially free of gaps against one another at their longitudinal and/or front sides. 
   
   
       20 . Arrangement according to  claim 1 , wherein a lower composite sheet adjacent to eaves is laid with the insulating material sheet against an eaves fillet and is adhesively bonded on the eaves side by means of an adhesive edge.
