GLOSSARY
BRIDGING: Occurs when the membrane is unsupported at a
juncture or angle change. Moisture condensing on the bottom
of the membrane can cause further delamination. Areas where
bridging occurs should be repaired and re-ashed.
CONTACT ADHESIVE: RoofKit Contact Adhesive is used
to adhere the eld membrane to substrate, walls and curbs. It
should be thoroughly stirred before using. (Do Not Use For
Seams)
COVER STRIP: Five inch (5") wide cured EPDM membrane
with butyl tape laminated to one side. Used when stripping in
metal edge details, repairing cuts in the eld membrane.
FASTENING SCREWS AND PLATES: Used to mechanically
attach (fasten) the insulation board to the roof deck.
TERMINATION BAR: Extruded aluminum bar used to
terminate the membrane at parapet walls, chimneys, skylights,
and AC curbs. Also used to terminate membrane to fascia
when no metal drip edge is used. The proper fastener should
be installed in every hole and a one-quarter inch (1/4") space
maintained between bars.
FISHMOUTH: A wrinkle is formed when an increasing amount
of membrane is forced onto an area too small to accommodate
the material. When the wrinkle ends at the edge of the material,
a conical opening is formed called a Fishmouth. Wrinkles and
Fishmouths in seams are not acceptable. They must be removed
and ashed in.
FLASHED OFF: Allowing the solvents in the adhesives or
primer to evaporate, leaving the material in a tacky, not wet or
stringy condition, before mating the two surfaces together. If
the proper Flash Off time is not allowed, blisters will form in
the membrane. Blisters will not harm the membrane and over
time, will usually disappear.
LATEX BONDING ADHESIVE: RoofKit Latex Bonding
Adhesive is used to adhere the eld membrane to the substrate.
It should be thoroughly stirred before using. (Do Not Use For
Seams)
