Paradiene 20 SA is a multi-purpose self-adhesive sheet that may be utilized in the Paradiene 20/30 Roof System. The back surface is coated with a self-adhesive bitumen layer specifically formulated for optimum adhesion in low-slope membrane applications and lined with high-strength polyolefin release film. End laps must be heat welded and a torch-applied finish layer of Paradiene TG, Veral, or Parafor must be applied in the same day. If same-day application is not possible, all laps of the Paradiene 20 SA should be heat welded.

A unique elastomeric blend formulated by SBS and high-quality proprietary asphalt.
Designed for use in homogeneous multi-layer modified bitumen roof membrane systems.
Available with Siplast RoofTag RFID.

Paradiene 20 HT SA

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 TS SA

Consists of a lightweight random fibrous glass mat impregnated and coated with an elastomeric SBS-modified bitumen. The unique back surface design consists of factory-applied, self-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 approved insulations and roof boards, primed structural concrete decks, and other approved substrates.

Finish or Cap Sheets

Paradiene 30, Cold Adhesive or SFT Adhesive Applied

Paradiene 30 FR are finish plies of the Siplast Paradiene 20/30 FR System. These granule-surfaced top ply, Paradiene 30, shields the base from the elements and mechanical abuse, while the base ply, Paradiene 20 absorbs roof stresses. These high performance, modified bitumen finish plies can be applied in approved Type IV asphalt, Siplast PA-311 Adhesives or SFT Adhesive.

Paradiene 30, Torch-Applied

Paradiene 30 FR TG and Paradiene MW FR are finish plies of the Siplast Paradiene 20/30 FR System. These granule-surfaced top ply, Paradiene 30, shields the base from the elements and mechanical abuse, while the base ply, Paradiene 20 absorbs roof stresses. These high-performance, modified bitumen finish plies are torch applied to approved substrates and the back surfaces are coated with a high-performance modified bitumen adhesive layer specifically 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.
