PVC combustion, smoke-inhalation risk, and the fire classifications that govern interior finishes — grounded in local standards and sources.
Marketing pages tell you what a product claims. Delivery ledgers tell you who actually buys it. Three years of records for our fire-rated film show a clear pattern: schools first, then care facilities, public buildings, and one 500-unit apartment order.
DI-NOC earned its place as the category benchmark, and its fire certifications are legitimate. The real fork in the road is chemistry: vinyl carries chlorine, and chlorine becomes hydrogen chloride in a fire. Here's an honest comparison framework.
Most people who die in building fires die from what they breathe, not from burns. The interior finish is often the fuel — and PVC finishes release hydrogen chloride gas when they burn.
