Description
SENTINEL P200 is a membrane composed of thermoplastic polyvinyl chloride (PVC) and a polyester reinforcement.
UNITS PER SKID: 10
Material Use:
SENTINEL P200 is a high-performance, single-ply roofing membrane designed for waterproofing applications on commercial and industrial flat or low-slope roofs. It is composed of thermoplastic polyvinyl chloride (PVC) reinforced with polyester, offering excellent mechanical strength, flexibility, and weather resistance. This membrane is suitable for new construction and re-roofing projects where a durable, energy-efficient, and UV-resistant roofing solution is required.
System Components:
SENTINEL P200 is used as the primary waterproofing membrane in a single-ply roofing system. It can be installed using three different methods: mechanically fastened, induction welded, or fully adhered with SENTINEL S Bonding Adhesive. The system includes:
- Primary Membrane: SENTINEL P200 (available in white and grey)
- Fastening Components: Screws and 2.4-inch plates for mechanical fastening or induction plates for induction welding
- Adhesive Option: SENTINEL S Bonding Adhesive for full-surface bonding
- Seaming Method: Hot air welding (manual or automatic) for all side and end laps
Applications:
SENTINEL P200 is intended for use in single-ply roofing systems on commercial, institutional, and industrial buildings. It is ideal for flat or low-slope roofs and can be used in both new construction and retrofit applications. The membrane is compatible with various installation methods, making it versatile for different project requirements and wind uplift conditions.
Application Details:
- Installation Methods: Mechanically fastened, induction welded, or fully adhered
- Seaming: All side and end laps must be hot air welded to a minimum width of 38 mm (1.5 in)
- Fastener Placement: For mechanical fastening, fasteners are installed in the 152 mm (6 in) side lap, 51 mm (2 in) from the edge
- Adhesive Application: When using SENTINEL S Bonding Adhesive, leave a 38 mm (1.5 in) adhesive-free zone at all laps for proper welding
- Membrane Orientation: On steel decks, install perpendicular to the ribs, with fasteners on the upper part of the ribs
Special Notes:
- Compatibility: SENTINEL P200 is not compatible with asphalt-based products, coal tar pitch, or uncoated extruded/expanded polystyrene
- UV Resistance: The membrane is UV stable and offers excellent solar reflectance, especially in white (initial SRI of 108)
- Environmental Ratings: White membrane has a solar reflectance of 0.85 (initial) and thermal emittance of 0.89, contributing to energy efficiency and compliance with Cool Roof Rating Council (CRRC) standards
- Thickness: 2.0 mm (80 mils) total thickness; 1.02 mm (40 mils) over scrim
- Coverage: Available in 1.5 m (5 ft) and 3 m (10 ft) widths, with lengths of 19.8 m (65 ft), covering 30.2 m² (325 ft²) or 60.4 m² (650 ft²) per roll
- Weight: 2.4 kg/m² (0.5 lb/ft²)
- Storage: Store rolls lengthwise on pallets in a clean, dry area, covered with tarps
Performance and Limitations:
- Temperature Range: Passes low temperature flexibility at -40 °C (-40 °F)
- Mechanical Properties: High breaking strength (77/53 kN/m), excellent tear resistance, and puncture resistance
- Dimensional Stability: Less than 0.1% linear dimensional change
- Water Absorption: Less than 3% weight change after water immersion
- Seam Strength: Meets ASTM D751 requirements (minimum 75% of breaking strength)
SENTINEL P200 is a robust and versatile roofing membrane that can be integrated into various roofing systems depending on project needs. When used with SENTINEL S Bonding Adhesive and appropriate mechanical or induction fastening systems, it forms a complete, high-performance waterproofing solution.
