Firestone EPDM Mechanically Attached Systems

Firestone EPDM Mechanically Attached Systems offer an economical installation method on buildings where the roof deck will provide sufficient pull out resistance for the fastening system and where the roof slope does not exceed 1:3.

Firestone offers three options for mechanical attachment of its RubberGard EPDM membranes, which can also be used in combination:

RMA System	MAS System	BIS System

Firestone RMA System

System Benefits

• Non penetrating
• Use of large EPDM panels
• Fast coverage
• Fewer seams
• Lightweight
• Aesthetics

System Installation

The RMA System is developed around the Firestone QuickSeam RMA strip, a 254 mm wide strip of reinforced EPDM membrane incorporating two strips of self-adhesive QuickSeam Splice Tape laminated along each edge over the entire length of the strip. The RMA strips are laid out over the substrate and mechanically secured to the roof deck. Spacing of the strips differs to accommodate to wind loadings. The EPDM sheets are then adhered to the mechanically attached RMA strips using the standard QuickSeam Splice Tape seaming techniques. In perimeter zones, membrane panels can also be fully adhered to the substrate instead of using the RMA strips. Adjoining sheets are overlapped a minimum of 100 mm and spliced with QuickSeam Splice Tape. All flashings around roof perimeters and penetrations are installed in accordance with Firestone specifications (pdf 1.598 kB).

Firestone MAS System

System Benefits

• Use of large EPDM sheets
• Fast coverage
• Fewer seams
• Lightweight

System Installation

Field zone membrane sheets are mechanically attached with batten strips placed on top of the sheets and protected with 152 mm wide Firestone QuickSeam Batten Cover Strips. Spacing of the batten strips will differ to accommodate to wind loadings. Perimeter zones may either be fully adhered or mechanically attached in accordance with the specification requirements. Adjoining sheets are overlapped a minimum of 100 mm and spliced with QuickSeam Splice Tape. All flashings around roof perimeters and penetrations are installed in accordance with Firestone specifications (pdf 1.598 kB).
 

Firestone BIS System

System Benefits

• Adaptable to unusual roof configurations
• High wind uplift performance
• Low material cost
• Lightweight

System Installation

The Firestone BIS (Batten-In-The-Seam) System is a variation of the conventional MAS System, which uses smaller EPDM sheets loose laid on the substrate. Perimeter zones may again be either fully adhered or mechanically attached in accordance with the specification requirements. Field zone membrane sheets are mechanically attached with an appropriate fastening system placed in the middle of the seams of adjoining sheets. The fastening pattern and the width of the sheets differ to accommodate for wind loadings. Adjoining sheets are overlapped at least 200 mm at side laps and 100 mm at end laps, and spliced with QuickSeam Splice Tape. All flashings around roof perimeters and penetrations are installed in accordance with Firestone specifications (pdf 1.598 kB).
