Arrowglass IV / Arrowglass VI
Arrowglass IV & VI are manufactured with a heavyweight fiberglass mat containing heat-cured resinous binders. High-strength glass mats are saturated with TYPE IV & TYPE VI asphalt respectively, giving Arrowglass IV & VI incredible strength and weathering capabilities, as well as a uniform porosity for ease in application. Arrowglass IV & VI are ply sheets used in hot mopped roofing applications and may be the basic ply sheets used in all smooth and gravel surfaced roofing systems requiring the ASTM D-2178 TYPE IV & VI felts.
Arrowbase is non-porous, 28lb. base sheets, uniquely designed and constructed to be simultaneously strong and wrinkle resistant. This unique combination of strength and suppleness is achieved by coating a heavyweight, specially designed fiberglass mat with type IV asphalt. The asphalt coating helps maintain a uniform consistency on both sides of the sheet and eliminates pinholes. Arrowbase is used as the base ply in a wide variety of hot, cold and torch-applied built-up and modified bitumen roofing applications. The suppleness and extreme pliability of Arrowbase makes it a good alternative for organic base where a decay resistant inorganic mat is desired.
Arrow 43 is an asphalt-saturated organic felt, coated with a high-quality asphalt coating. Arrow 43 is used as a base ply in a number of BUR applications and is non-perforated, which makes it an ideal vapor retardant.
Venting Base Sheet is an asphalt coated fiberglass base sheet for use in built-up roof systems that has been coated on the underside with mineral granules. The mineral granules are then embossed leaving a grid pattern in the sheet for superior venting characteristics.
