SYNTHETIC ROOFING UNDERLAYMENT”
CornerStone CS110 Synthetic Roofing Underlayment
CornerStone CS110 is a highly engineered, mechanically attached, coated woven synthetic roofing underlayment for sloped roofs. CornerStone’s durable and high strength design along with its fiber grip walking surface provides a considerable improvement over asphalt saturated felt. The fiber grip textured walking surface can also be chalked just like felt.
Homeowner’s Best Choice
No oil leaching – no hazardous material content
Lays flat and does not absorb water and wrinkle
Low temperature flexibility
Gone are the days of blow-offs and call backs! CornerStone CS110 is 6 times stronger than #30 felt and therefore offers superior wind resistance and durability through heavy roof traffic and adverse weather conditions. Stay on track, take on more jobs and sleep assured your CS110 projects will remain intact and dried-in. CornerStone CS110 will save you time and money with less material damage and fewer post-install repairs.
Unlike traditional asphalt saturated felts, CornerStone CS110 can be used in extremely low temperatures without becoming stiff and difficult to unroll. It also does not dry out, crack, or leach oils in the heat like felt. CornerStone CS110 is 100% synthetic and will not absorb water and wrinkle like felt. It lays flat and will remain 100% impervious to mold.
CornerStone CS110 will continue to protect your long life primary roofing long after felt has turned to dust! Unlike felt, CornerStone CS110 is also backed by a 20 year manufacturer’s limited warranty.
