Yes, lexan used for the top sheet. Yes, it was left in the sun. Yes, it was left outside. However, I've read on multiple locations that lexan is an acceptable material second only to HDPE.

rgrwilco Thats weird. On my box i used HDPE because of experience with using lexan on the jibs at my local resort and having to replace it often.

Nice thought, but I'm 99.9% positive that its the lexan. The warping is actually quite impressive. I will attempt a pic.

Warped lexan

I built a 10 foot box last year out of treated lumber and used 1/4" lexan as a top sheet. First of all the lexan was 200$ for a 4x8 sheet. So I figured must be the cats ass. Had to cut a 2ft section to make it 10 ft long. The finished product was quite nice at the time. However, this summer the top sheet warped like hell literally ripping the screws from the wood and or pulled screws through the top sheet ie ruined.

Any insight or suggestions by experienced builders? Is the warping inevitable? Better ways to secure? Intrinsic problems with lexan?
