Insulating materials are often installed under the slopes of the roof, but there are cases when the panels were placed directly on the elements of the roof itself. Before proceeding with the insulation of the attic, it is worth making sure that the surfaces are prepared, all materials are purchased and tools are collected. You can use mineral wool as a heater, but at the same time you need to use aluminum foil, which will avoid moisture. During the work, it is worth thinking about the ventilation holes, which should be located in the upper and lower parts of the attic. Of course, before starting insulation work, it is worth consulting with the masters in this area.
