Metshield High Temp Underlayment From Drexel Metals

Metshield® High Temp (HT) underlayment from Drexel Metals protects roof structures from water seepage caused by ice dams and wind driven rain. Designed for high-temperature applications of metal roof installations, it will resist temperatures up to 250°F without degradation of the adhesive. The underlayment self-seals around roofing nails, screws, and clips that are used to install the primary roofing system. The high-tensile strength underlayment is a 40 mil SBS modified bitumen with a UV-resistant anti-slip polyethylene woven top facer. It is required under all Drexel Metals roof warranted systems.metal roof

In April 2016, MetShield HT underlayment was issued a Product Control Notice of Acceptance (NOA No.: 16-0322.26) for use in Miami-Dade County and its municipalities. MetShield HT has been designed to comply with the Florida Building Code, including the High Velocity Hurricane Zone of the Florida Building Code. MetShield HT meets the requirements of ATSM D1970, for self-adhering polymer modified bituminous sheet materials used as steep slope roofing underlayment for ice dam protection.

Made in the U.S., Metshield HT bonds directly to the roof substrate without the need for additional adhesives. The product resists cracking, drying and rotting, and the concealed waterproofing system will not detract from the architectural aesthetics of the primary roofing system. Exposed rubberized asphalt bead along the membrane edge ensures watertightness of lap seam.

Commenting on the Miami-Dade acceptance, Jim Alex, SE Regional Sales Manager of Drexel Metals, said, “This is great news for our installer and fabricator members of the ARM (Association of Regional Manufacturers) using our Gold Standard Warranty in Dade and Broward counties.”

In addition to its recent acceptance in Miami-Dade County, the MetShield HT underlayment product meets the following standards: UL Classified; ICC-ES ESR #2206; 2009 and 2012 International Building Code; and ASTM D1970.
