POLYDAN PLUS F.M 180-60/GP FRBR ELAST. is a waterproofing bituminous sheet with self-protected surface of 5.6 kg/m². Composed of a reinforced and stabilized polyester felt reinforcement, covered on both sides with SBS modified bitumen mastic. On the upper side of the sheet, slate in grey (black) colour is used as protective material. The anti-adhesive material used on the lower side is polyethylene film.

Instruction for Use

    1. Fist of all, center the plinth on the deck ceiling opening.
    2. Fix the plinth to the deck with steel lag screws:r- Three units per meter on the plinth’s perimeter heel. Over concrete slab supports, domes will be installed with concrete screws, washers and Ø6mm lag screws. Over steel deck systems with thermal insulation and waterproofing membrane, domes will be installed with steel screws directly to the structure. If the skylight has to be place before the steel deck, an auxiliary frame welded to the main structure will be required.
    3. Install the waterproofing membrane covering the exterior plinth surface.
    4. Remove the dome’s protector film.r Place the inferior dome over the plinth and over the.
    5. Place the inferior dome over the plinth structure and install the self-adhesive washers on the inferior dome top surface, matching them with spaces to be drilled. Screw the top methacrylate dome, finishing the whole skylight. Do not tight screws in excess, because:
  • Domes could be broken.
  • Expansion joint effect will be nullified.
    6. Place finish cads over the screws.
IMPORTANT: Do not install the dome until plinth has been placed in order to avoid any stain related to waterproofing works.
