EPDM Ballasted
is the fastest and most economical installation method, suitable for roof structures that can support a minimum dead load of 10 lbs. per square foot and with slopes of less that 3/4" per foot. This technique has proven performance, and is particularly suited for new construction.

EPDM Fully Adhered
This method can be used on virtually any roof deck, and is especially suitable where lighter weight is required or where the roof has unusual contours or multiple penetrations. Applicators can choose from a full selection of adhesive products offered by StaFast: StaSafe waterbased bonding adhesive, FasSeal all purpose bonding, seam and flashing adhesive, and StaBond neoprene-based bonding adhesive.

EPDM Mechanically Attached
This is an economical system using wide membrane sheets and long batten bars for attachment to wood, steel, or other suitable roof decks. StaFast supplies a complete line of Fas N’ All bars and screws for these applications.

EPDM Plate Bonded
This is a partially adhered system that utilizes FasLok (12” x12”) modified polystyrene bonding plates. The plates are secured to the substrate underneath the membrane, thus creating a secure holding system with no mechanical penetrations of the EPDM sheet.

TPO/TPA Fully Adhered
Although TPA standard membrane can only be mechanically attached, TPA fleece-back membrane may be fully adhered to an approved substrate using StaSafe water-based latex adhesive. TPO membrane may be fully adhered using FasWeld TPO bonding adhesive in the two-sided contact method.

TPO/TPA Mechanically Attached
This is the most commonly used method for installing reinforced thermoplastic membrane. Depending on the spacing of the plates, this system can qualify for FM I-90 up to FM I-105 approval.
