Maximum Recommended Spans
The following data is based upon uniform loading of corrugated FRP panels with a safety factory of 2.5, and fastened as recommended.
NOTE: Table is based on a section properties or actual load test. Design loads are governed by local building codes. Conduct code
authorities for specific load and stresses. Information is provided as preliminary data for designers. It should be checked and verified for
use with a duly licensed engineer or architect.
Framing
Provide purlin members at recommended maximum intervals required for corrugation section. See chart above for first column.
CUTTING
Cut fiberglass panels using hand or power saws. Saw blades should be fine-toothed carbide tipped, or safety fabric reinforced abrasive
disc. Face shields and appropriate safety equipment should be worn.
DRILLING
All panels should be pre-drilled not less than 1-1/2” from panel end holes drilled a minimum of 1/16” larger than the fastener diameter.
Panels may be drilled singly or several at a time.
BASIC FRP INSTALLATION INSTRUCTIONS
These instructions are intended as guidelines for proper installation procedures. In the use of tools, fasteners, sealants, and adhesives,
follow manufacturer’s recommended procedures.
Installation
For best protection against prevailing winds and weather, install panels beginning at leeward end of run and work to windward.
1. Provide a minimum of one corrugation overlap at sides.
2. Provide 8” end-laps for roofs with pitch of less than 4/12. Use 6” end-laps for pitches greater than 4/12.
3. Fasten panels through crowns at every second corrugation.
Fasteners with armored Neoprene washers are
recommended. Space fasteners 6” to 8” on-center along
panel edges and 12” to 16” on-center for intermediate rafters
and blocking.
Construction Notes
1. To avoid deflection of panels, tighten screws until washers will not rotate, then tighten one more turn.
2. Avoid excess burrs on drilled or punched holes to protect Neoprene sealing face.
3. To help insure weather tight roof, apply a small amount of clear sealer at each hole before installing nails or screws.
Recommended Overlap
(2.67” x 9/16”) Overlaps shown will provide best protection against leakage and air infiltration. Vinyl lap seal and/or mastic must also be
used to achieve effective seal on side-laps and end-laps.
Typical Fasteners
Include aluminum or galvanized nails or wood screws with Neoprene washers. Fastener selection is dependent upon type of corrugation
and under structure material used. Panels should be pre-drilled a minimum of 1/16” larger than fastener diameter.
• #10 x 2” Galvanized “polebarn” screw with 1/2” armored Neoprene washer.
• 1-3/4” x .145” Alum. helix nail (screw nail) with Neoprene washer.
UNDER NO CIRCUMSTANCES should panels be allowed to support undistributed loads such as the weight of a human body.
Use only approved roof ladders and planking.
