PCV foam board..

[vwt2salty]

Hey all, im new here and i had a couple of questions for all you expert aquasport rebuilders out there.

Im currently refiting a 19-6. I am replacing the entire deck with PCV foam board, vs the standard marine plywood. the reason i went with foam board is because it is closed cell; so it wont absorb any water.

i was wondering if any one has done this before or if they have even heard of it? it was recomended to me by the carpenter that works for my company. i will be posting some pics later tonight.

let me know your thoughts/ feelings.. THANKS!!!

I guess the first question I would ask is about its density and the ability to hold a screw in place; the console and T-top would be a good example. Using toggle bolts and backing plates to hold everything down may be an issue. I`ll assume it is compatible with resins and expoxies. What is the primary application for this type of material for its designed use. There are a large amount of composite materials out there and you are in good hands discussing with our members their own experiences with composite materials.

Third, are you talking about the pink or blue insulation board?
If you are talking about these I don't think they will work on a deck. They are sometimes okay as a filler for encapsulating, but not as a structural piece. If for example you used them to form stringers and wrap them with biax and get the thickness correct it could work. Then again if you used them for a deck Fitz is correct that without the correct backing and glass thickness on the panels you could have some issues. The one thing I totally agree with Fitz about is the compatibility of resins with the board. Poly resins might melt it and even epoxies might delaminate after a period of time. This is why Coosa or marine ply are such good materials for these jobs. If weight is a factor then Nidacore is your best bet. I would hate to do all the work and find out when done that it failed. Coosa, Nidacore, Nyloboard, and of course marine ply all have properties where resins if done correctly will stick for a very long time and never have an issue.

Thanks! im not exactly sure of its intended use, however  it holds a screw like wood and i spoke to the rep of the company that i bought it from and he told me that what ever compounds or epoxies stick to fiberglass will also stick to this foam board (i spoke to him this morning).
 i guess that i want to be overly confident that this will work; this is my first boat rebuild and there is alot of info to take in.

When it comes to re doing your boat dont reinvent the wheel. Use the tried and true methods of boat building. There is a reason they have been around for so long. Alot of knowledge here when it comes to fixing these old girls up. Everything from glass work to electronics to basic rewiring of the boat.
