Performance, Fire Safety, and Long‑Term Reliability
At BaseTec, we understand that effective water management and fire safety are two critical considerations in modern construction. As regulations continue to tighten and expectations rise, specifiers and contractors require solutions that deliver proven performance without compromise. These exact considerations were central to Visqueen’s approach when developing the latest generation of the Zedex Non‑Combustible DPC Cavity Tray Systems.
A Quick Look at How it Works
The Visqueen Zedex Non‑Combustible DPC and Cavity Tray System is intended for use in cavity wall constructions, including those incorporating a structural framing system inner leaf and a masonry outer leaf, across residential, commercial, and multi‑storey buildings. When correctly installed, the system provides effective moisture management while maintaining the fire performance of the wall construction, supporting compliance with the requirements of the Building Regulations.
Zedex – Designed for Today’s Fire Safety Requirements
As requirements for construction materials become increasingly stringent, it is more important than ever to choose trusted, compliant products that ensure projects meet modern standards without sacrificing performance. Meeting these demands is central to Visqueen’s approach, a fact that is clearly demonstrated in the Zedex Non‑Combustible DPC Cavity Tray System.
The flexible composite damp proof course achieves a reaction to fire classification of A2‑s1, d0 in accordance with BS EN 13501‑1:2018, making it suitable for applications where restrictions on combustible materials apply. In addition to providing freely accessible, full fire‑classification reports, Visqueen also provides compliance with:
- The Building Regulations 2010 (England and Wales)
- The Building (Scotland) Regulations 2004 (as amended)
Fast and Efficient
Drawing on more than five decades of construction expertise, Visqueen understands that time on site matters. That’s why the Zedex Non‑Combustible DPC Cavity Tray System has been carefully engineered with installation efficiency at its core. An innovative, redesigned fixing system allows installers to work more quickly and confidently, achieving up to 80% faster installation while maintaining the highest standards of quality and safety.
