Description
Self-adhesive base sheet composed of a glass mat reinforcement and SBS modified bitumen.
ITEMS PER SKID: 25
Material Use:
SOPRAFLASH STICK is a self-adhesive SBS-modified bitumen base sheet membrane designed for use in roofing and waterproofing systems. It is primarily used as a base flashing membrane in multi-layer roofing assemblies, offering excellent adhesion and flexibility for detailing around roof penetrations, upstands, and other critical areas.
System Components:
SOPRAFLASH STICK is used in conjunction with ELASTOCOL STICK primers to ensure optimal adhesion to the substrate. It serves as the base sheet in a multi-layer system and is typically followed by the installation of a compatible cap sheet membrane. When installed as part of a complete SOPREMA roofing system, it contributes to a durable, watertight assembly.
Applications:
This membrane is suitable for use in roofing applications, particularly in areas requiring detailed flashing work. It is ideal for use on vertical surfaces, parapets, and other areas where a self-adhesive membrane is preferred for ease of installation and reliable adhesion. SOPRAFLASH STICK is compatible with various substrates, provided they are primed appropriately.
Application Details:
- Surface Preparation: Substrates must be clean, dry, and free of loose particles. Prior to installation, the surface must be primed with ELASTOCOL STICK primer to ensure proper adhesion.
- Installation Method: The membrane is applied by removing the silicone release film and pressing the membrane onto the primed surface. A membrane roller should be used to apply uniform pressure across the surface. End laps require priming with ELASTOCOL STICK and welding of the final 25 mm (1 in) using a hot-air welder. If the cap sheet is installed the same day, welding of laps is not required, provided the full width is primed.
- Minimum Application Temperature: 0 °C (32 °F)
- Thickness: Nominal thickness is 2.5 mm (98 mils); minimum selvedge thickness is 2.25 mm (89 mils)
- Dimensions: 15 m x 1 m (49 ft x 3.3 ft) per roll
- Selvedge Width: 100 mm (4 in)
- Reinforcement: Glass mat
- Surface Finish: Sanded
- Underface: Self-adhesive with silicone release film
Special Notes:
- Environmental Conditions: Installation should not be performed below 0 °C (32 °F). Ensure dry conditions during application to maintain adhesion quality.
- UV Resistance: SOPRAFLASH STICK is not UV-stable and must be covered with a compatible cap sheet or other protective layer.
- Storage: Rolls must be stored upright with the selvedge side on top. If stored outdoors, they must be protected with an opaque cover after removing the delivery packaging.
- Water Vapour Transmission: Very low permeability (< 2.5 ng/Pa•s•m²), contributing to excellent waterproofing performance.
- Flexibility: Maintains flexibility down to -30 °C (-22 °F), making it suitable for cold climates.
- Compatibility: Must be used with ELASTOCOL STICK primer for proper adhesion. Compatible with SOPREMA cap sheets for complete system integration.
SOPRAFLASH STICK is a reliable and easy-to-install base sheet membrane that forms an integral part of SOPREMA’s multi-layer roofing systems. Its self-adhesive nature and compatibility with ELASTOCOL STICK primer make it ideal for detailed flashing work and vertical applications, ensuring long-term waterproofing performance.
