Durable and easy to install, SOPREMA’s SENTINEL product line offers the reliable fire and chemical protection inherent to PVC membranes as well as superior weldability under a wide range of environmental conditions. Thanks to their superior flexibility and suppleness, our membranes can be installed on the most complex shapes, whether they are low or steep slopes.
The membranes can be mechanically fastened or adhered with adhesive and are available in several versions: with a smooth underface or laminated to a polypropylene needle felt, with non-woven polyester or fibreglass diagonal reinforcement, in thicknesses of 60 mils and 80 mils.
They meet the requirements of the Cool Roof Rating Council (CRRC) for white reflective membranes that promote cooling in buildings, and reduce both energy consumption and the urban heat island effect.

SENTINEL P membranes are strengthened with a high-performance capillary-resistant polyester reinforcement designed to provide superior tear resistance as well as unparalleled long-term performance.
Thanks to their superior tear resistance, SENTINEL P membranes are not only ideal for roofs with mechanical fastening systems, but they also offer exceptional dimensional stability to adhered systems.
*According to published data
SENTINEL membranes have a minimum thickness of 60 mils with at least 30 mils above the reinforcement to provide a compound that is much more weather resistant than competitive brands. The top and bottom layers contain no recycled PVC, to ensure long-term performance without any compromise.
The polyester thread with enhanced density provides superior tear and puncture resilience, while the insertion of a weft prevents breakage and tears from getting worse. Competitors offer products with fibreglass threads with lower tensile strength properties, which increase the risk of membrane rupture and tear. The polyester thread of the SENTINEL P membrane resists capillarity action and thus promotes weld conditions, in addition to eliminating the need for sealing joints and improving the performance and integrity of the roof system’s waterproofing.
The roof of a section of this Sudbury hospital needed a facelift since the 1990s. After some research, the mandated architectural firm agreed to specify SOPREMA SENTINEL PVC membranes for the project. The long-term durability of the product, the peace of mind thanks to the competitive guarantees of the system, as well as the superior service of SOPREMA convinced the stakeholders of the project to choose SENTINEL membranes.
Versatility and diversity; two words that perfectly describe our SENTINEL PVC product line. These products have a polyester reinforcement and can be applied in different ways requiring no flame, thus ensuring safety during installation: fully adhered, mechanically fastened, induction welded.
