A recently granted patent (Publication Number: US11821210B1) outlines a method for installing a roof system using a specific membrane composite. The method involves providing two membrane composites, each consisting of a polymeric planar body with UV-cured pressure-sensitive adhesive layers and pre-applied primer layers. The first membrane composite is adhesively secured to the roof surface, followed by the adhesively securing of the second membrane composite, positioned adjacent to and partially overlapping the first. The second membrane composite is then secured to the first membrane composite along the pre-applied primer layer.

Additionally, the method includes steps such as removing a release member, extending a lap area along the lateral edge of the polymeric planar body, and utilizing specific primer compositions for the pre-applied primer layer. The UV-cured pressure-sensitive adhesive layer is characterized by its thickness and glass transition temperature, derived from butyl acrylate or 2-ethylhexyl acrylate units. The second membrane composite is provided in the form of a roll, requiring the unrolling process during installation. This patented method offers a detailed and structured approach to efficiently installing a roof system using specific membrane composites and adhesive layers, ensuring a secure and durable application process.
