-Polyester reinforced for high strength and flexibility at all temperatures

-Non-woven polyester, 180g/m2 reinforcement

-SBS polymer provides flow resistance at high temperatures and flexibility at low temperatures for lasting durability

-Excellent tear resistance

Application:

Application surfaces need be prepared per guide specifications

modifiedPLUS NP180gT4 must be thermofused by standard roofing torch or hot air heat gun. Roll out modifiedPLUS NP180gT4 and allow to relax prior to application.

Begin application of the cap sheet at the lowest edge or drain. Proceed up the slope from the lowest point. Position and unroll cap sheet to achieve correct overlap and alignment. Re-roll one end a minimum of 10' and adhere membrane to substrate. Complete application of remainder of sheet.

Thermofused Application: Heat lower surface of membrane evenly across width of roll. Sufficient heat should be applied to melt the lower surface and provide a flow of bitumen. At the same time unroll the roofing membrane into the melted bitumen. Care should be taken to ensure that heating is even across the width to avoid skips or voids and bitumen should flow out from lap to ensure a tight seal. Add matching granules to cover the excess bitumen flow at seams.
