IKO Marathon Plus AR shingles are of solid construction.
IKO Fastlock sealant strips along the bottom edges have one of the fastest tack times in the industry, even in extreme cold weather applications*. When activated by the sun’s radiant heat, they become extra-tacky and create a strong, aggressive bond to ensure maximum protection against wind uplift, blow-off and water penetration. That means potentially fewer call-backs for you.
*Please refer to installation instructions regarding the need to manually seal the shingles in cold weather applications.
