Clamps for insulated pipes BISOFIX® are applied in places where it is necessary to anchor the distributions mechanically and at the same time maintain the continuity of the insulation of the distributions. When applied correctly, BISOFIX® clamps prevent the formation of thermal bridges and condensation, reduce the risk of corrosion under the insulation, prevent energy losses, save time on the construction site and increase the efficiency of assembly.
