SHINGLE UNDERLAYMENT

This eave and valley protection membrane is an SBS modified bitumen membrane which is sanded on both sides with fiberglass reinforcement. This SBS modified bitumen components significantly improve the underlayment’s flexibility. It has a 44 in (1.12 m) 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 12 in (300 mm) from the inside of the exterior wall. This can be achieved, most of the time, with only one membrane width.
