<p>The insulation is made from PVC plastic film (1) strongly attached to the roof covered with plastic roof elements, it is equipped with at least one coating (81, 82, 83, 84) based on an aqueous dispersion of acrylic polymer, perhaps even containing varnish. A quantity of coats (81, 82, 83, 84) corresponds to the condition of the roofing. The resulting thickness of one layer (81, 82, 83, 84) is from 0.10 mm to 0.60 mm, and the last coating reflects more than 90% of solar radiation. Into the second coat may be inserted technical fabric (91) or (92). The method of applying sandwich damp-proofing it is described too.</p> |
