ProctorPassive DriFlash Tape

UV resistant vapour permeable single sided tape

Categories: ,

ProctorPassive DriFlash Tape is a UV-resistant, single-sided vapour permeable and air-tight tape made with a unique vapour open acrylic pressure-sensitive adhesive with superior ageing resistance. DriFlash Tape is the ProctorPassive UV-SA membrane cut into a manageable width for tape applications.

ProctorPassive DriFlash Tape is ideal for air-tight bonding and sealing of penetrations, adjoining external insulation boards, sheathing, CLT, window frames and overlaps of vapour-permeable membranes. The tape can bond to multiple substrates listed below.


  • UV Resistance
  • High Vapour permeance (AS4200.1: 2017 Class 4)
  • No primer required on most clean substrates
  • Tough material resists punctures and tears
  • Multiple substrate compatibility
  • Wide service temperature range
  • Low VOCs
  • Initial low tack for adjustability
  • Exceptional air tightness
