PRODUIT - Resistoflex (FR-EN)

RESISTOFLEX eave and valley protection membrane is an SBS modified bitumen membrane which is sanded on both sides with fiberglass reinforcement. RESISTOFLEX‘’s SBS modified bitumen components improve significantly the underlayment’ flexibility. RESISTOFLEX has 1.12 m (44 in) width and meets, in most cases, the requirement of the National Building Code by having an underlayment membrane that covers the roof area by at least 300 mm (12 in) from the inside of the exterior wall. This can be achieved, most of the time, with only one membrane width.


  • Non-slip, sanded finish
  • Effective and hard-wearing
  • Withstands exterior temperature fluctuations
  • Clean and easy to install
  • Consistent thickness
  • Significantly improves the underlayment flexibility
  • Meets all the requirements of ASTM D4601
