Description
High performance panel composed of SBS modified bitumen membrane with a non-woven polyester reinforcement, factory-laminated on a high density mineral fibre (stone wool) board.
UNITS PER SKID: 30
Material Use:
2-1 SOPRASMART ROCK is a high-performance, factory-laminated base sheet panel designed for use in roofing systems. It combines a durable SBS-modified bitumen membrane with a high-density mineral fiber (rock wool) insulation board. This product is primarily used as a base layer in multi-ply roofing assemblies, offering both waterproofing and thermal insulation in a single application.
System Components:
The system consists of the following components:
- Base Sheet: SBS-modified bitumen membrane reinforced with non-woven polyester and surfaced with a thermofusible plastic film.
- Insulation Layer: High-density mineral fiber (rock wool) board, available in various thicknesses (15.9 mm, 25.4 mm, and 38.1 mm).
- Adhesives (optional): DUOTACK adhesive for adhered applications.
- Fasteners (optional): SOPREMA screws and plates for mechanical fastening.
- Hot Bitumen (optional): SEBS or oxidized bitumen for mop-applied installations.
- Lap Treatment: DUO SELVEDGE with a self-adhered section and a torch-applied section; end laps are sealed with SOPRALAP membrane.
Applications:
2-1 SOPRASMART ROCK is suitable for use in commercial and industrial roofing systems, particularly where a combination of thermal insulation and waterproofing is required. It is compatible with steel deck substrates and is designed for use in both adhered and mechanically fastened roofing systems. The product is ideal for new construction and re-roofing projects.
Application Details:
- Installation Methods: Can be installed using hot bitumen, DUOTACK adhesive, or mechanically fastened with SOPREMA screws and plates.
- Orientation: Panels must be installed perpendicular to steel deck ribs, with fasteners placed on the top flanges of the deck.
- Lap Sealing: Side laps feature a DUO SELVEDGE (self-adhered and torch-applied), while end laps must be aligned and sealed with SOPRALAP.
- Panel Dimensions: 0.914 m x 4.88 m (3 ft x 16 ft).
- Selvedge Width: 75 mm (3 in).
- Membrane Thickness: Minimum 2.2 mm (85 mils).
- Total Panel Thickness: Ranges from 18.1 mm (0.71 in) to 40.3 mm (1.59 in), depending on insulation thickness.
Special Notes:
- Thermal Resistance: R-value of 4.0 (hr·ft²·°F/BTU) for 25.4 mm (1 in) insulation thickness.
- Compressive Strength: 12 psi at 10% deformation, 28 psi at 25% deformation.
- Fire Resistance: Mineral fiber board exhibits dimensional stability at 650 °C (1200 °F) with only 1.1% shrinkage.
- Water Resistance: Low water absorption (1.2%) and vapor sorption (0.29%).
- Storage: Must be stored flat and protected from weather. If stored outdoors, cover with an opaque protective cover.
- UV Resistance: The membrane is surfaced with a thermofusible plastic film and is not intended for UV exposure. It must be covered with additional roofing layers or surfacing.
- Environmental Conditions: Specific temperature and humidity limits during installation are not provided in the TDS, but standard SBS membrane application guidelines should be followed (typically above 5 °C / 41 °F and in dry conditions).
- Compatibility: Can be used with SOPREMA’s DUOTACK adhesive and SOPRALAP membrane for complete system integration.
This product is a part of SOPREMA’s SOPRASMART roofing system and is designed to work in conjunction with other SOPREMA membranes and accessories to form a complete, high-performance waterproofing and insulation solution.
