IKO revamped its Roof-Fast Base and Cap sheets for the U.S. and Canadian markets to come in full squares instead of short square rolls, aligning with how roofers measure and estimate materials. The self-adhering base and cap sheets are constructed of a reinforcing mat of nonwoven glass fibers and, when paired together, provide multilayer coverage on low-slope roofs. The cap sheets, which have a granule finish, can also be used alone. iko.com
