Trex® RainEscape Trough: Installtion
 
When working with the Trex® RainEscape trough material, ensure that the smooth/ shiny side always faces up. Do Not Seam Or Overlap The Troughs To Extend Its Length.
Line up the 1-1/2” score with the second joist.
At the ledger slide 3” of trough under existing siding or flashing ensuring trough sits on top of ledger board.
Place first staple at ledger board on inside joist to tack trough (Fig. 4).
Unroll trough to downspout using 1-1/2” score mark on inside joist as guide.
Cut length to back wall of downspout, cutting a 1” wide by 3/4” tab at center edge of trough (fold tab down) to prevent wicking (Fig. 5).
To remove memory from sheet, backroll the last few inches of the trough (Fig. 6).
Pull trough tight ensuring memory is released and place second staple on inside joist through downspout (Fig. 7).
On outside joist, form a trough into downspout while lining up the edge of trough with outside of joist. Place third staple through trough and downspout on outside joist (Fig. 8).
Pull corner at ledger and outside joist tight keeping entire length of trough smooth and wrinkle-free; place fourth staple on outside joist at ledger (Fig. 9).
To test for correct slope, pour cup of water on trough at ledger board ensuring water runs to downspout.
Continue stapling every 6” to 8” from ledger to downspout on both joists to secure.
