Enduro Tuff Span - Fiberglass (FRP) Louvers & Vents

Enduro Tuff Span fiberglass louvers and ridge vents provide effective air control and long service life for applications with demanding structural and environmental conditions. Our fiberglass (FRP/GRP) louvers and ridge vents contain over 50% glass reinforcing content in chemical composition. This high glass content combined with the premium iso-polyester resin provides extreme strength, durability, and resistance to aggressive chemicals. Enduro industrial louvers and ridge vents have a long, proven history of standing up to tough chemical exposures and high windstorms. The fire retardant fiberglass components in the ventilation units have a Class I flame spread rating of 25 or less per ASTM E84.
