Base & Ply sheets
Double layer, double performance
Although a single ply of DERBIGUM roofing membrane is fully waterproof, the multi-ply redundant system provides added security against punctures.
This exceptionally long-lasting durability is especially important for rooftops that are prone to heavy traffic.
Two or more layers that overlap each other provides security against leakage or damage.
