PU coated fiberglass fabric: fiberglass cloth treated with polyurethane coating.
Better abrasion & chemical resistance, stays flexible under heat. Widely used for welding blankets, fire/smoke curtains, insulation covers, fabric air ducts and expansion joints.
Here’s the debate I keep hearing:
Many specifiers automatically pick silicone coated fiberglass for every fire safety project. But is silicone always the right call?
For projects with heavy rubbing, chemical splashes and tight budget, PU-coated fiberglass often outperforms. The catch: coating quality makes or breaks long-term stability.
What’s your go-to? Silicone or PU coated fiberglass for welding blankets & fire curtains?
