EnglishEnglishRoofnado™ LapLock™ PSU HT is a high-performance sealing tape designed for secure overlap bonding in roofing systems. Heat-resistant and durable, it ensures strong adhesion, reliable waterproofing, and long-term weather protection.
(Self-Adhered Roofing Underpayment)
Roofnado™ LapLock™ PSU HT is a self-adhered roofing underpayment designed to provide reliable protection for sloped roof applications. It creates a continuous waterproof layer that helps prevent wind-driven rain, snow, and moisture from penetrating the roof structure.
The material improves adhesion to roof decking and fasteners, which enhances installation performance and overall system durability. In addition, its slip-resistant surface increases safety during installation.
Roofnado™ LapLock™ PSU HT works with asphalt shingles, metal roofing systems, and other common roofing materials. As a result, it provides consistent performance across residential and light commercial projects in Canadian climate conditions.
