Stone wool insulation products marked with an asterix (*) in the table are sold with extra features for special applications e.g. with a fleece, aluminium foil etc. The extra features are demonstrated in the Annex. The impacts from the additional features shall be added to the final result. The scaling calculation shall follow the following formula: Environmental Impact per m2 product X-with facing = Environmental Impact reference product * scaling factor + Environmental Impact facing material Note that, for different R values (where the thickness is not equal with the thermal conductivity) the final scaling factor is given by multiplication with the real R value. This can be explained below: Environmental Impact Rreal = Environmental impact R=1 * RrealFinally, for the products with (**) on the table above the respective national provisions at the place of use apply for the use and application of the product.
