MMMF insulation with fiberglass coating Glass veil is a non-woven material composed of uniformly distributed glass fibers bound by organic additives. In addition to traditional urea and melamine based binders, our research and development department continuously test new binder formulas to provide innovative solutions, i.e. soft touch glass veil for mineral wool surfacing, formaldehyde free glass veil for indoor air quality, binder based on renewable resources, etc - http://www.adfors.com/us/technologies/glass-mat/glass-veil-e...
