Polyglass has redesigned the manufacturing process to develop patent-pending SEALLap ULTRA.

SEALLap ULTRA is the patented, granule-free, and self-adhesive compound in the side lap of Polyglass’ ADESO® granulated cap sheets.
By applying self-adhesive compound in the granule-free side lap, as well as the bottom layer, ADESO Self-Adhered modified bitumen membranes now offer a side-lap with greater shear strength than any other mod-bit roofing assembly. This includes torch, mop cold process, or any other non-Polyglass self-adhered roofing membrane. When compared to similar membranes and traditional application methods:

  • Cold Process – SBS Modified Bitumen Membrane 3.14 Seam Peel Testing (lbf)
  • Torch Applied – APP Modified Bitumen Membrane 7.16 Seam Peel Testing (lbf)
  • Hot Applied – SBS Modified Bitumen Membrane 7.54 Seam Peel Testing (lbf)
  • Self-adhered – SBS Modified Bitumen Membrane 7.73 Seam Peel Testing (lbf)

The newly redesigned manufacturing process applies a self-adhesive compound to the side lap as well as on the bottom layer of the membrane. SA to SA bond of SEALLap ULTRA has many benefits:

  • Labor and time savings
  • More efficient and less costly installation
  • Instant side lap bond
  • Monolithic seal
  • Cleaner application
  • Safe, no open flame application
  • Superior watertight sealing
