The membrane roof panel is a five-rib roof panel carrying a PVC membrane on its outer face. The membrane is used on low-pitch roofs where a pre-painted steel surface alone is not sufficient, and in environments exposed to chemical attack.
In this version the core is polyurethane: thermal conductivity 0.022 W/mK, fire class B-s1-d0 with a PIR core. Thickness goes up to 200 mm and the panel is produced in single lengths of up to 15.5 metres; on a membrane roof, a low number of joints is a direct gain in watertightness.
In solutions where the membrane and the steel sheet are two separate layers, delamination occurs over time. For the version in which the membrane is laminated to the steel sheet, see the TRIPAN PU page. Joint details are in the Library section.
