<p>The invention relates to a nailing flange blanket, comprising a substantially flat carrier of flexible material and a layer of mineral wool which is adhered to the carrier, wherein the carrier extends on either side of the layer of mineral wool and wherein the carrier comprises a layer of aluminium foil, wherein the carrier comprises a layer of plastic imparting strength to the carrier. Plastic is a material which is less flammable than paper. The calorific value of a plastic layer is suprisingly smaller than the calorific value of a paper layer of the same strength. The greater strength of the plastic plays a part here; it is possible to suffice with a thinner layer of plastic.</p> |
