Abstract: A method of providing a snow storage with heat-insulation, the method including covering a snow pile made at a snow storage site with heat-insulating materials of which at least some are insulation boards. In the method, the insulation of the snow pile is carried out by using insulation board mats which include several insulation boards, or insulation board groups consisting of several insulation boards attached against each other, side by side and/or one after another, and which are pivotably joined together, alternately at the upper corners and the lower corners of their opposite transversal end edges, the resulting continuous insulation board mat composed of several insulation boards one after another being foldable into an accordion-like insulation board bundle and re-openable into a continuous insulation board mat. The invention also relates to equipment for providing a snow storage with heat-insulation.

Abstract: A method for handling insulating materials used for storing snow, wherein the insulating materials covering a heap of snow stored through the summer are taken off the heap of snow before the snow in the heap of snow is transferred to a selected use. In the method, the insulating materials used for covering the heap of snow stored through the summer are transferred to such another use, in which the insulating materials have at least one function other than mere storage of the insulating materials.
