Description
SENTINEL G150 is a membrane composed of thermoplastic polyvinyl chloride (PVC) and a fiberglass reinforcement.
UNITS PER SKID: 20
Material Use:
SENTINEL G150 is a high-performance waterproofing membrane designed for use in single-ply PVC roofing systems. It is primarily used for detailing work in roofing applications, such as flashing and edge terminations, where flexibility and durability are essential. The membrane is reinforced with fibreglass and composed of thermoplastic polyvinyl chloride (PVC), offering excellent mechanical properties and long-term weather resistance.
System Components:
SENTINEL G150 is used in conjunction with SENTINEL S Bonding Adhesive for full-surface adhesion. The system requires hot air welding for sealing side and end laps, with a 38 mm (1.5 in) adhesive-free zone around all seams to ensure proper weld integrity. An automatic hot air welder, dedicated exclusively to PVC membranes, is recommended to enhance the quality and speed of installation. SENTINEL G150 is not compatible with asphalt-based products, coal tar pitch, or uncoated extruded/expanded polystyrene, and should not be used in contact with these materials.
Applications:
This membrane is suitable for use in commercial and industrial roofing systems where a durable, UV-resistant, and energy-efficient waterproofing solution is required. It is ideal for use in both new construction and re-roofing projects, particularly in areas requiring detailed waterproofing such as parapets, curbs, and penetrations.
