Use foam closures under ridge flashing, see below. Also closures at lower edge of roof sheets and at top and bottom of wall sheets. Sundance does not provide flashing.
At the ridge the closures are placed between the ridge flashing and the polycarbonate. Closures 3 feet long. To determine needs take linear footage of top and bottom of sheets and divide by 3.
Procedure: Begin by installing roof sheets. Wall sheets installed butt against roof panels. Use closures as shown in drawings. Sheet metal flashing is installed after sheet is in place. Corner Trim may be used, see Layout Close-up.
