1. A method of fabricating an insulation element as an insulation box, cap or cover for a valve, a flange or a fitting within a piping system of a technical building equipment comprising the steps of forming a block of insulating material to be provided with a cavity having a contour of the valve, the flange or the fitting and an outer contour, whereby the block is divided into at least two parts, preferably two halves of the insulation box, cap or cover, and forming a complementary insulating covering having an inner contour according to the outer contour of the block, whereby the block and the complementary insulating covering are produced separately from each other and joined together, whereby the block is produced from mineral wool and the complementary insulating covering is produced from a plastically deformable material being mechanically pressed or molded to be provided with the inner contour corresponding to the outer contour of the block provided with the cavity, wherein a glass fibre scrim reinforcement embedded between two layers of aluminum each having a thickness of 10 μm to 30 μm, preferably of 18 μm is used as primary material for the plastically deformable material.
