The G2 Grease Guard Rooftop Defense
Systems protect your roofing system from the damaging effects of
corrosive grease, oil, chemicals or fluids that are discharged during
routine manufacturing operations. Petroleum-based oils, motor oil
and hydraulic fluid are used in numerous types of manufacturing
facilities. Oil- and chemical-laden air is vented from the
facility and deposited onto the roof via exhaust fans or piped discharge
applications. The G2 Grease Guard protects building owners from
costly roof repairs, voided roof warranties, unnecessary fire
hazards and excessive liability claims. Just a few of the
manufacturing effluents that can substantially damage unprotected
roofing systems are shown below.

Filter Diagram
|
|
|
- Top Pre-Filter - a
pass-thru, noncombustible, self-extinguishing filter constructed
from an open cross section polymer.
- Transfer Layer -
constructed from polyolefin fiber. Designed for quick transfer
of oil-based fluids to the absorption layers, while repelling
rainwater. UV stability protects the absorption layers from
damaging sun rays.
- Advanced Filter Composite -
constructed from an engineered open cell polyolefin fabric.
Over 100 layers of absorbent microfibers wick and contain oil based
fluids, while repelling rainwater. Absorption capacity is up
to 78 fluid ounces per square foot.
|
- Barrier Layer - constructed from a closed cell polymeric
blend that provides a leak proof barrier.
- Bottom Layer - an airflow layer constructed from an open
cross section polymer. This layer supports the absorption and
security layers while allowing air to circulate throughout the
entire filter system.
- Fire Shield - a fire-proof barrier that protects the
roof & building from any potential exhaust system fire hazard.

Sizing
|
- Measure the area where grease actually drips, splashes and
sprays (A) around the exhaust equipment. Disregard any areas
where gravity moves the grease (B.)
- Add 30" to length (A) and width (A) from Step 1 to
determine the closest G2 Grease Guard size needed.
- For example, if area (A) is 50" x 58", add 30"
to each measurement to get 80" x 88" (C). Use the
80" x 88" (C) to select a 90" square unit.

|
Installation
|
- Assemble the frame around the problem area. The frame
system consists of the patented "Quick Corners" (A) and
the heavy duty aluminum frames (B), which bolt together using an
allen wrench (C) (included) as shown below.
- Measure and draw the exhaust equipment cut-out area on the
filters. Be sure to measure for a snug fit. Use scissors
to cut the filter materials (D). Once filter materials are
cut, tuck into frame around exhaust equipment.
- Screw the grease deflecting flashing to the exhaust equipment
curb (E) on all sides. The flashing directs the grease
directly into the absorbent filter system.
