Petersen, maker of PAC-CLAD architectural metal cladding systems, now offers PAC-CLAD HT high-temperature, self-adhering roof underlayment, which is designed to provide premium waterproofing protection for a variety of roofing applications. PAC-CLAD HT underlayment offers protection against water and ice damming while withstanding extreme weather conditions.

The self-adhering qualities of PAC-CLAD HT reduce labor costs and installation times while providing increased protection compared to that of typical felt roofing underlayment. This strong, 40-mil, skid-resistant, high-tensile-strength rubberized asphalt membrane is designed to withstand temperatures up to 250 degrees Fahrenheit and is available in either black or white. It will not crack, dry out or become brittle, even under the most extreme weather conditions, resulting in permanent protection and low life cycle costs. The rubberized asphalt is laminated to an impermeable polyethylene film layer.

“PAC-CLAD HT will not only perform well over the lifetime of a metal roof, it will simplify the purchasing process for our contractor customers, who can now acquire all components of a metal roofing system from one source, including underlayment, metal panels and fasteners,” said Mike Weis, vice president of sales and marketing at Petersen. “Petersen continues to keep the interests of roofing installers at the top of its priority list by introducing products like this that perform well and make their jobs easier.”
