<p>The basic roof shell is covered by a layer of insulating material coated with ethylene vinyl acetate copolymer. This in turn is covered by the roof sheeting which is a laminate e.g. of polychloroprene as the top surface and an ethylene vinyl acetate copolymer backing. The sheeting is stuck to the coated insulating material and the butt joints are taped with roof sheeting.</p> |
