Product: Xspect Isofoam APF Board and Cross-Flo Metal Jacketing

Description: The Xspect ISOfoam APF Board is a closed cell polyisocyanurate foam core bonded to a foil facer on both sides, and Cross-Flo Jacketing is a metal jacketing system designed to help mitigate corrosion under insulation (CUI). Pairing the two products provides high R-value and weather resilience. Xspect provides a moisture barrier insulation for rooftop ducts. Using tapered Xspect at the top of the insulation system helps to prevent ponding water and assist in precipitation drainage away from a rooftop duct. When combined with Cross-Flo Jacketing using a weep hole on the underside of the duct, any potential moisture has an easy exit from the system. This reduces the need for repairs over the lifetime of the entire system.
