Description
Self-adhesive high performance cap sheet membrane with a composite reinforcement and SBS modified bitumen.
UNITS PER SKID: 25
Material Use:
SOPRAPLY STICK TRAFFIC CAP is a high-performance, self-adhesive SBS-modified bitumen cap sheet membrane designed for use in roofing systems. It serves as the top layer in multi-ply waterproofing assemblies, providing enhanced durability and protection against weathering, mechanical stress, and UV exposure. The membrane is reinforced with a composite mat and surfaced with coloured granules for added protection and aesthetic appeal.
System Components:
SOPRAPLY STICK TRAFFIC CAP is typically used as the final cap sheet in a multi-layer SBS-modified bitumen roofing system. It is installed over a compatible base sheet or underlayment, such as SOPRAPLY STICK base membranes. The system requires the use of ELASTOCOL STICK primers to ensure proper adhesion to the substrate. The DUO SELVEDGE technology incorporated into the membrane allows for immediate and secure sealing of side laps, enhancing waterproofing performance.
Applications:
This membrane is suitable for use in commercial and industrial flat or low-slope roofing applications where a durable, traffic-resistant, and self-adhering cap sheet is required. It is ideal for new construction, re-roofing, and roof recovery projects. SOPRAPLY STICK TRAFFIC CAP is particularly effective in areas subject to moderate foot traffic and where flame-free installation is preferred or required.
Application Details:
- Installation Method: Self-adhesive application by removing the split-back silicone release film. Pressure must be applied using a membrane roller to ensure full adhesion.
- End Laps: Apply cold adhesive to the first 100–125 mm (4–5 in) and weld the last 25–50 mm (1–2 in) using a hot air welder.
- Side Laps: Finish by welding the last 25 mm (1 in) with a hot air welder and membrane roller.
- Priming: Substrates must be primed with ELASTOCOL STICK primers before membrane installation.
- Minimum Application Temperature: 0 °C (32 °F).
- Surface Preparation: Substrates must be clean, dry, and free of loose particles.
Special Notes:
- Thickness: Minimum thickness before heat conditioning is 3.8 mm (150 mils); after heat conditioning, 2.8 mm (110 mils).
- Selvedge Thickness: Minimum 2.8 mm (110 mils) before heat conditioning; 1.8 mm (70 mils) after.
- UV Resistance: The membrane is surfaced with coloured granules, providing UV resistance.
- Temperature Resistance: Compound stability up to 91 °C (196 °F).
- Low Temperature Flexibility: Maintains flexibility down to -27 °C (-17 °F); after UV weathering, down to -12 °C (10 °F).
- Storage: Rolls must be stored upright with the selvedge side on top. If stored outdoors, they must be covered with an opaque protective cover.
- Dimensions: Each roll measures 10 m x 1 m (33 ft x 3.3 ft).
- Weight: Minimum mass per unit area is 4.8 kg/m² (100 lb/100 ft²).
- Puncture Resistance: Passes standard puncture resistance tests.
- Granule Embedment: Less than 2.0 g (0.07 oz), indicating strong surface granule retention.
This product is part of a flame-free, self-adhered SBS-modified bitumen roofing system and should be used in conjunction with compatible base sheets and primers for optimal performance.
