Products / DynaClad Ultra HT Wind & Water Seal

DynaClad Ultra HT Wind & Water Seal is a self-adhering waterproofing underlayment of a non-slip cross-laminated polymer film laminated to a high temperature rubberized asphalt adhesive with a split release liner, engineered for use under metal roofing. The cut sheet lists a 45 mil nominal thickness, a white surface, 36 inch by 67 foot rolls, a 250 degree F maximum temperature and installation at 50 degrees F or above, with tests to ASTM D5147, D1970, E96 and D903. It is used as a whole-roof underlayment or at eaves, valleys, rakes and penetrations, and DMI requires a full layer on the roof field for slopes under 3:12. The sheet states it is covered under the DynaClad Metal Roofing System Limited Warranty.
