These curtains are made with an 13 or 18 oz. Flame Retardant Vinyl
and are available in combination with a clear PVC window that is also
flame retardant. Chain can be sewn in the bottom hem to provide for
light wind resistance. Both materials meet California Fire Marshall (CFM)
standards for flame resistance.
The clear material is not meant for welding purposes. Our weldview
material can be substituted if a welding application is needed.
