Paradiene 20 TG is the first ply of Paradiene 20 TG/30 TG Systems. The base ply is an elastomeric asphalt blend reinforced with a fiberglass that absorbs roof stresses, while the granule-surfaced top ply, Paradiene 30 TG or Parafor 30 TG, shields the base from the elements and mechanical abuse. These high-performance, modified bitumen-finish plies are torch-applied to approved substrates. The top surfaces are covered with a silica parting agent or perforated burnoff film and the back surfaces are coated with a high-performance modified asphalt adhesive layer specially formulated for torch applications. The adhesive layers are manufactured using a special process that embosses the surface with a grooved pattern to provide optimum burnoff of the plastic film and maximize application rates.

  • A unique elastomeric blend formulated by SBS and high quality proprietary asphalt.
  • Designed for roof membrane systems.
  • Available with Siplast RoofTag RFID.

Paradiene 20 TG

Consists of a lightweight random fiberglass mat impregnated and coated with high-quality SBS-modified bitumen. Designed to be used as a base ply for direct application to approved roof board products and other approved substrates.

Paradiene 20 TS

Consists of a lightweight random fibrous glass mat impregnated with high-quality SBS-modified bitumen. The unique back surface design consists of factory-applied, heat-activated adhesive stripes combined with a proprietary acrylic coating between the stripes, which provides for uniform bonding of 50% of the total surface area of the sheet. Designed for direct application to primed structural concrete decks, approved insulations, and other approved substrates.

Paradiene 20 HT TG

Consists of a high tensile fiberglass scrim/fiberglass mat composite impregnated and coated with high-quality SBS-modified bitumen. Designed to be used as a base ply for direct application to approved roof board products and other approved substrates.

Paradiene 20 HT TS
