Apply elastomer modified bitumen SBS on top of the Wolfin IB waterproofing membrane. Apply the top layer of sealing membrane (PYE PV 200 SS) as a cover layer up to the lower edge of the clamping strip by folding it over the Wolfin membrane (sealing membrane width approx. 500 mm). Caution: Avoid heat build-up and permanent open flame on the Wolfin IB sealing membrane - risk of burns!
