SOPREMA DuoFlex is a hot-applied, elastomeric structural waterproofing system suitable for inverted roofs, zero fall applications, roof gardens, blue roofs, and protected roofs. It holds UK BBA (British Board of Agrément) certification, verifying its compliance with independent performance criteria for durability, weather resistance, and waterproofing.
Reliable waterproofing performance
DuoFlex is a fully bonded system, creating a continuous waterproof layer that adheres directly to the substrate. Its self-healing properties allow the material to seal minor surface damage, contributing to its long-term waterproofing performance. The system is also compatible with fast-track and phased installation methods, supporting project scheduling requirements.
Fire performance and durability
DuoFlex systems have been tested to meet the highest industry classifications for external fire exposure when installed with specified coverings. In addition, SOPREMA provides product warranties, subject to conditions, of up to 30 years for the single-pour system and up to 40 years for the double-pour system.
Sustainability considerations
DuoFlex is designed with long service life in mind, which can help to reduce material use and the need for replacement over time. SOPREMA also offers technical guidance, including site inspections, project calculations, and design support to assist with correct specification and installation.
With BBA certification supporting its tested performance claims, SOPREMA DuoFlex provides a robust waterproofing solution for a range of roofing applications.
