Proship - Product Detail.

Delivers exceptional weather barrier performance compared to traditional asphalt products and other synthetic underlayments. 7 times lighter, covers 5 times more area, and is 20 times stronger than 30# felt. Mechanically nailed down with plastic cap nails or staples, using fewer fasteners per square than conventional felts. The top side contains a proprietary rubber-modified polyolefin coating which has a high level of slide resistance. The back side is designed to reduce slippage between the underlayment and the roof sheathing. Can be easily bent for forming around corners, valleys, and ridges. Features a khaki surface that stays cooler to work on and keeps buildings cooler during the dry-in time of construction, while still absorbing sunlight on cold days to help reduce frost. Does not support mold growth, rot, or dry out. Does not contain asphalt and is 100 percent recyclable and UV resistant for up to six months. Meets ASTM E108, UL 790, and UBC 15-2.
