<p>The invention relates to a panel for air ducts, formed by a mineral-wool-based core having an external covering and provided with scoring guidelines for forming prismatic-section ducts by means of folding. In addition, the panel includes oblique marking lines which, together with lines transverse thereto, can be cut to form respective portions used as elbows, changes of direction or junctions in the duct. One of the panel body edges includes a band marked with lines, shading or another form of delineation corresponding to the limit to be reached by an aluminium adhesive tape used to secure the flap on the male side of the duct, corresponding to the safety zone that has to be covered with adhesive tape in order to achieve adhesion and sealing which ensure satisfactory leaktightness between different sections of air distribution ducts.</p> |
