system.
• Z-DENS is manufactured from environmentally safe and
sustainable fire retardant polypropylene, offering superior
performance.
• Z-DENS does not require explosive or toxic cleaners, primers
or cements; eliminating the safety and health concerns
associated with these products.
• Z-DENS Self-Sealing design does not require any curing time,
significantly reducing installation times and allows immediate
system start up.

where PVC is NOT PERMITTED.
