Description
High performance base sheet panel composed of SBS modified bitumen membrane with a non-woven polyester reinforcement, factory-laminated on a HD polyisocyanurate insulation support panel (SOPRA-ISO PLUS HD).
UNITS PER SKID: 70
Material Use:
2-1 SOPRASMART ISO HD SANDED 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 polyisocyanurate insulation board (SOPRA-ISO PLUS HD), providing both waterproofing and thermal insulation in a single product. This material is primarily used as a base sheet in multi-layer roofing assemblies for commercial and industrial flat or low-slope roofs.
System Components:
This product is a composite system consisting of two main components:
- Top Layer: SBS-modified bitumen membrane reinforced with non-woven polyester and finished with a sanded surface.
- Bottom Layer: High-density polyisocyanurate insulation board (SOPRA-ISO PLUS HD), providing thermal resistance and compressive strength.
The system is compatible with the following accessories and complementary products:
- Adhesives: DUOTACK adhesive for adhered applications.
- Primers: ELASTOCOL STICK primer is required when applying SOPRALAP STICK membrane over end laps.
- Fasteners: SOPREMA screws and plates for mechanical attachment.
- Lap Treatment: SOPRALAP STICK membrane for sealing end laps, used in conjunction with ELASTOCOL STICK primer.
- Hot Bitumen: SEBS or oxidized bitumen for mop-applied installations.
Applications:
2-1 SOPRASMART ISO HD SANDED is used in commercial and industrial roofing systems as a base sheet panel. It is suitable for new construction and re-roofing projects over steel decks and other compatible substrates. The product is designed for use in multi-layer SBS-modified bitumen roofing systems and is ideal for applications requiring high compressive strength, thermal insulation, and waterproofing performance.
Application Details:
- Installation Methods:
- *Hot Bitumen:* Applied using SEBS or oxidized bitumen with a mop.
- *Adhesive:* DUOTACK adhesive is used for adhered applications.
- *Mechanical Fastening:* Fastened with SOPREMA screws and plates according to wind uplift requirements.
- Lap Sealing:
- Side laps feature a DUO SELVEDGE: the first portion is self-adhered, and the second portion is sealed using a hot-air welder (SOPRAMATIC recommended for optimal results).
- End laps must be aligned and covered with SOPRALAP STICK membrane, applied over ELASTOCOL STICK primer.
- Panel Dimensions:
- Available in 3 ft x 8 ft and 3 ft x 16 ft sizes.
- Total thickness: 14.9 mm (19/32 in), with 12.7 mm (1/2 in) insulation thickness.
- Membrane Thickness:
- Minimum 2.2 mm (85 mils).
- Weight:
- 4.15 kg/m² (0.85 lb/ft²).
Special Notes:
- Environmental Conditions:
- The product must be stored flat and protected from weather. If stored outdoors, it must be covered with an opaque protective cover.
- Temperature and Flexibility:
- Low temperature flexibility: -18 °C (-0.4 °F).
- Compound stability: up to 121 °C (250 °F).
- Thermal Resistance:
- R-value of 2.5 for the 12.7 mm (0.5 in) insulation layer.
- Compressive Strength:
- 550 to 759 kPa (80 to 110 psi).
- Water Absorption:
- Less than 3% by volume.
- 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.
- Thickness Limits:
- Membrane thickness is fixed at 2.2 mm (85 mils); insulation thickness is 12.7 mm (1/2 in).
- Coverage:
- Each 3 ft x 8 ft panel covers 24 ft²; each 3 ft x 16 ft panel covers 48 ft².
This product is designed to be used as part of a complete SOPREMA SBS-modified bitumen roofing system and must be installed according to SOPREMA guidelines and local building codes. For optimal performance, always consult with a SOPREMA representative for project-specific recommendations.
