The 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 manufacturingfacilities.  Oil- and chemical-laden air is vented from the facility and deposited onto the roof via exhaust fans or piped discharge applications. The 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

1. Top Pre-Filter - a pass-thru, noncombustible, self-extinguishing filter constructed from an open cross section polymer.
2. 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.
3. Filter - 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.

4. Barrier Layer - constructed from a closed cell polymeric blend that provides a leak proof barrier.
5. 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.
6. Fire Shield - a fire-proof barrier that protects the roof & building from any potential exhaust system fire hazard.

Sizing

1. Measure the area where grease actually drips, splashes and sprays (A) around the exhaust equipment.  Disregard any areas where gravity moves the grease (B.)
2. Add 30" to length (A) and width (A) from Step 1 to determine the closest size needed.
3. 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

1. 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.
2. 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.
3. 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.
