Description
High performance base sheet panel composed of SBS modified bitumen membrane with a non-woven polyester reinforcement, factory-laminated on a high density fire-resistant fibreboard (SOPRAFIBRE) support panel.
UNITS PER SKID: 70
Material Use:
2-1 SOPRASMART FB SANDED is a high-performance, factory-laminated base sheet panel designed for use in multi-layer SBS-modified bitumen roofing systems. It serves as a base sheet and insulation board in commercial and industrial roofing applications, offering both waterproofing and fire-resistant properties.
System Components:
This material is composed of two integrated components:
1. SBS Modified Bitumen Membrane – Reinforced with non-woven polyester and finished with a sanded surface.
2. Support Panel – A high-density, fire-resistant fibreboard (SOPRAFIBRE) laminated to the membrane.
The system may include the following additional components for complete installation:
- Primer: ELASTOCOL STICK (used before applying SOPRALAP STICK on end laps)
- Adhesive (optional): DUOTACK adhesive for adhered applications
- Fasteners (optional): SOPREMA screws and plates for mechanical fastening
- Lap Treatment: SOPRALAP STICK membrane for end laps
- Hot Bitumen (optional): SEBS or oxidized bitumen for mop-applied installations
Applications:
2-1 SOPRASMART FB SANDED is used as a base sheet in SBS-modified bitumen roofing systems. It is suitable for new construction and re-roofing projects on commercial and industrial buildings. It can be installed over steel decks and other compatible substrates using hot bitumen, DUOTACK adhesive, or mechanical fasteners.
Application Details:
- Installation Methods:
- *Hot Bitumen:* Applied with a mop using SEBS or oxidized bitumen
- *Adhesive:* DUOTACK adhesive
- *Mechanical Fastening:* SOPREMA screws and plates, installed on top flanges of steel decks
- Lap Sealing:
- Side laps feature a DUO SELVEDGE: the first portion is self-adhered, and the second portion is sealed using a propane torch or hot-air welder (SOPRAMATIC recommended for speed and quality).
- End laps must be aligned and covered with SOPRALAP STICK membrane, applied over ELASTOCOL STICK primer.
