Material Use:
2-1 SOPRASMART BOARD SANDED is a high-performance, factory-laminated base sheet panel used in roofing systems for waterproofing applications. It combines an SBS-modified bitumen membrane with a non-woven polyester reinforcement and a sanded surface, laminated onto a semi-rigid asphaltic support panel (SOPRABOARD). This product is designed for use as a base sheet in multi-layer roofing systems, particularly in commercial and industrial flat roof assemblies.
System Components:
The 2-1 SOPRASMART BOARD SANDED is a composite product consisting of two main components:
- Top Layer: SBS-modified bitumen membrane with non-woven polyester reinforcement and a sanded surface.
- Bottom Layer: SOPRABOARD, a semi-rigid asphaltic support panel available in three thicknesses: 1/8 in (3.2 mm), 3/16 in (4.8 mm), and 1/4 in (6.3 mm).
This product is typically used in conjunction with:
- ELASTOCOL STICK Primer – used to pre-coat surfaces before applying SOPRALAP STICK at end laps.
- SOPRALAP STICK Membrane – used to seal end lap joints.
- DUOTACK Adhesive – for adhered applications.
- SEBS or Oxidized Bitumen – for hot-mopped applications.
- SOPREMA Screws and Plates – for mechanical fastening.
Applications:
2-1 SOPRASMART BOARD SANDED is used as a base sheet in SBS-modified bitumen roofing systems. It is suitable for:
- Commercial and industrial flat roofs.
- New construction and re-roofing projects.
- Systems requiring high puncture resistance and dimensional stability.
- Applications over steel decks, where it can be mechanically fastened, adhered, or hot-mopped.
Application Details:
- Installation Methods:
- Hot Bitumen: Applied in a bed of SEBS or oxidized bitumen using a mop.
- Adhesive: Adhered using DUOTACK adhesive.
- Mechanical Fastening: Fastened with SOPREMA screws and plates to steel decks, ensuring fasteners are placed on top flanges and membranes are installed perpendicular to deck ribs.
- Lap Treatment:
- Side laps feature a DUO SELVEDGE: the first part is self-adhered, and the second part is sealed using a hot-air welder (SOPRAMATIC recommended for efficiency).
- End laps must be aligned and covered with SOPRALAP STICK membrane, applied over a surface pre-coated with ELASTOCOL STICK primer.
- Panel Dimensions: 0.914 m x 2.44 m (3 ft x 8 ft)
- Selvedge Width: 90 mm (3.5 in)
- Total Thickness: Ranges from 5.4 mm (7/32 in) to 8.5 mm (3/8 in), depending on the SOPRABOARD thickness.
- Weight: Ranges from 6.6 kg/m² (1.3 lb/ft²) to 11.9 kg/m² (2.4 lb/ft²)
Special Notes:
- Environmental Conditions:
- Low temperature flexibility: -18 °C (-0.4 °F)
- Compound stability: up to 121 °C (250 °F)
- No specific humidity or temperature limits during installation are provided, but standard SBS roofing practices should be followed (typically above 5 °C / 41 °F and dry conditions).
- UV Resistance:
- The sanded surface is not UV-stable and must be covered with a cap sheet or other UV-resistant top layer in the roofing system.
- Performance Characteristics:
- High puncture resistance (500 N / 112 lbf)
- Excellent compressive strength (up to 11,100 kPa / 1,610 psi)
- Low water absorption (2.5%)
- Dimensional stability within ±0.5%
- Meets CSA A123.23 (Type B, Grade 3) and CSA A123.25 standards
- Storage:
- Store flat and protect from weather. If stored outdoors, cover with an opaque protective cover.
System Compatibility:
2-1 SOPRASMART BOARD SANDED is designed to be used as part of a multi-layer SBS-modified bitumen roofing system. It must be overlaid with a compatible SBS cap sheet for UV protection and long-term performance. It is compatible with SOPREMA’s range of primers, adhesives, and cap sheets, forming a complete waterproofing system.
This product is ideal for use in high-performance roofing assemblies where durability, ease of installation, and system compatibility are critical.
