Looking for a vendor that sells fiberglass sheets for subdeck. I found sheets on McMaster car that should suit my needs but like to keep options open
The few that I've seen go this route, use the sheet on mcmaster. I looked at it, but it's way too rich for me. I'll stick with $20 Baltic birch ply.
I use Lexan to replace my warped birch ply decks sometimes. like Will said, the FB decks are spendy. my sealing techniques are getting better though, so I will likely just be able to stick with plywood.
I've been using a foamed PVC board for my decks. It's relatively light weight, can be worked with standard woodworking tools and bonds well with many adhesives. You can also use PVC sprinkler adhesive. What I like most is that it takes a standard wood screw really well
