Key Features:
- Self-adhered: Specially formulated high-tack adhesive forms an immediate, long-lasting bond to a variety of substrates.
- SBS modified: Composed of a proprietary elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen formulation.
- Polyester reinforced: Reinforced with tough, dimensionally stable non-woven polyester mat.
- Multi-ply base: Designed as a base ply for approved multi-ply membrane and flashing assemblies.
- Aggregate topside: Topside is surfaced with fine mineral aggregate to facilitate self-adhered or cold adhesive applications.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose SOPRALENE Stick where you want torch-free base ply installation—the self-adhesive bonds immediately, which is valuable on heat-sensitive or occupied buildings. Ensure the substrate is clean, dry and primed where required so the high-tack adhesive achieves full bond. Use it within an approved Soprema multi-ply assembly rather than as a stand-alone membrane.
Follow the manufacturer's application instructions and site safety requirements for self-adhered membrane work; ensure adequate ventilation and substrate preparation before bonding.
Start your multi-ply assembly right with Soprema SOPRALENE Stick Base Ply self-adhered membrane.
