Westlake Royal Building Products™ (Westlake Royal), a Westlake company (NYSE:WLK), has introduced Citadel PRO, a self-adhered poly-coated base sheet that provides superior protection and simplified installation for roofers, when compared to mechanically fastened base sheets. Citadel PRO, which will be available in the Florida market, features a styrene-butadiene-styrene (SBS) modified asphalt core that self-seals around nail or screw penetrations to offer increased leakage protection.
“We know that installation efficiency is important for roofing contractors and understand how valuable reducing installation time can be,” says Eric Miller, vice president of sales, Westlake Royal Building Products’ stone and roofing solutions brands. “Citadel PRO represents a significant advancement in roofing underlayment technology, combining superior weather resistance with contractor-friendly installation features while maintaining the highest standards of protection.”
Citadel PRO is equipped with an easy-to-use peel-and-stick application to maximize deck adhesion and a poly-coated top surface for increased cap sheet adhesion while eliminating the need for special tools or hot asphalt in the adhesion process while also providing superior moisture resistance and thermal stability. The poly-surface provides excellent foot traction and offers up to three months of UV resistance, perfect for uncovered exposure during the construction process.
Designed to be used with Westlake Royal TileSeal™ HT, Westlake Royal MetalSeal™ HT and GatorSeal® underlayments, Citadel PRO carries a 30-year manufacturer’s warranty when installed under Westlake Royal TileSeal HT and MetalSeal HT and a 20-year warranty when used under GatorSeal. Citadel PRO has been rigorously tested and certified to meet ASTM D1970 standards and Florida Building Code for both HVHZ and non-HVHZ regions as listed in FL14317; it is available in 3′ x 66.7′ rolls covering 200 square feet.
