Product Information Sheet
F54 GlasPly4
Type 4 Glass Ply Sheet

USES: F54 GlasPly4 is used to construct built-up roofing and waterproofing membranes. These membranes form a water shield over such structures as roofs, foundations, and decks.

DESCRIPTION: F54 GlasPly4 is an asphalt coated fiberglass ply sheet. Select raw materials have been formulated into a 1.80 lb fiberglass sheet. GlasPly4 is your best defense against attacks from weather, acid rain, ozone, and chemicals. With GlasPly4, your roofing and waterproofing membranes will perform much longer. GlasPly4 has an Underwriters Laboratories (UL) Class A Fire Rating when installed in specified systems.

DIRECTIONS: Store F54 GlasPly4 on end. Keep protected from damage and humidity. Install base sheets with GlasPly4, the substrate is required to be firm, clean, dry, and smooth. Use any of the following as a base sheet: M60 RubrPoly, M64 RubrPoly2, F50 PolyShield, M62 RubrGlas, M66 RubrGlas2, F52 GlasBase2, or F55 PolyShield2. Apply the base sheet so that the flow of water is over or parallel to the seams. Lap the base sheet 2" on the side laps and a minimum of 4" on the end laps. Extend the base sheet to the head of all cants. Secure the base sheet to the substrate by either nailing or adhering. Nailed base sheets, use nails with 1" heads and nail the base sheet 9" on center on both the outside edges and the seams. Also, nail two rows 12" in from each edge on 18" centers, and alternate the nails in each row so that they are offset from each other. Adhered base sheets, apply either Fields hot asphalt or ambient asphalt and lightly broom the base sheet into the asphalt as it is unrolled. Hot asphalt installations, apply either MT3 RubrPac or T3 MeltPac at the rate of 25 lbs per 100 square feet. Ambient asphalt installations, use either M150 RubrSeal, M100 RubrCoat, or F100 PowrCoat at the rate of 5 gallons per 100 square feet. Install an extra base sheet in valleys and waterways. This extra sheet shall extend at least 8" up the inclines of valleys and be applied as specified for adhered base sheets. Install ply sheets with GlasPly4, the base sheet or substrate is required to be firm, clean, dry, and smooth. Apply GlasPly4 ply sheets parallel to the base sheet so that the flow of water is over or parallel to the seams. Apply 2, 3, or 4 ply sheets in shingle fashion on the correct laylines. Start by cutting and installing the starter strips and continue by installing the ply sheets in a uniform interply application of either MT3 RubrPac or T3 MeltPac hot asphalt at the rate of 25 lbs per ply sheet per 100 square feet: Or apply M150 RubrSeal, M100 RubrCoat, or F100 PowrCoat ambient asphalt at the rate of 5 gallons per ply sheet per 100 square feet. Make end laps a minimum of 4". Adjacent end laps shall be offset at least 12" apart. Lightly broom the ply sheets into the asphalt as they are unrolled. Install the surface coating with GlasPly4, the ply sheets are required to be firm, clean, dry, and smooth. Adhere an extra base flashing strip on all flashings at the same rate of asphalt as required for adhering base sheets. Extend the extra base flashing a minimum of 2" above the head of the cants and a minimum of 4" beyond the toe of the cants. Then, uniformly coat the entire surface with any one of the following: MT3 RubrPac, T3 MeltPac, M150 RubrSeal, M100 RubrCoat, F100 PowrCoat, M700 RubrGard, or F700 PowrGard. For hot asphalt coatings, apply 25 lbs per 100 square feet. For ambient asphalt coatings, apply 5 gallons per 100 square feet. For maximum protection and reduced energy costs, apply M800 RubrStar over the asphalt coating. Allow the asphalt coating a minimum of 90 days to set up before applying RubrStar.
