Product Description
Installation and
Technical Literature

Henry 189 Fiberglass Roving is a continuous filament glass fiber with approximately sixty strands held together loosely in rope form by a special sizing. The emulsion and glass fibers are spray applied simultaneously using a glass chopper spray gun (chopped to a typical length of 3/4") to provide a reinforced asphalt emulsion coating and waterproof monolithic surfacing. Applying the normal rate of 9 gallons, Henry 107 Asphalt Emulsion and 3 pounds, glass fiber, increases the film’s tensile strength by four times that of an unreinforced film.


  • For use with the Monolithic™ System for roofing and waterproofing (Henry 100, 107, or 109 emulsions)
  • Enables double the film thickness without shrinkage cracks
