Is this a "New" PT plywood?

[marquette]

i was in Menards this morning and came across this new PT wood they are changing over to. my question is "is this something new or just new marketing for an old product?". it's MicroPro AC2 Pressure Treated wood by Osmose Inc.
they claim it is environmentally friendly and ALUMINUM SAFE! the link to the manufacture is www.osmose.com.
i know that there are people here that feel PT has no place on a boat and others that swear by it. the way i see it is we always have to keep our eyes open to new products and if they will work. if our predecessors didn't we would all be still using wood boats caulked with hemp and tar.

Re: Is this a "New" PT plywood?

I copied this off of the website and link you provided. It was under the fastener section.

For interior or exterior applications use fasteners and hardware that are in compliance with the Manufacturer?s recommendations and the building codes for their intended use.

Aluminum building products may be placed in direct contact with MicroPro? treated lumber and other wood products used for interior uses and above ground exterior applications such as decks, fencing, and landscaping projects.

Examples of aluminum products include siding, roofing, gutters, door and window trim, flashing, nails, fasteners and other hardware connectors. However, MicroPro? treated lumber and other wood products in direct contact with aluminum products should only be used in code compliant construction applications that provide proper water drainage and do not allow the wood to be exposed to standing water or water immersion. We recommend you contact the aluminum building product manufacturer for their recommendations regarding their aluminum products in contact with MicroPro? treated wood used in ground contact applications or when MicroPro? treated wood is exposed to salt water, brackish water, and chlorinated water, such as swimming pools or hot tubs.

Also check with the aluminum product manufacturers regarding compatibility with other chemicals and cleaning agents. Contact Osmose for further information on aluminum contact use in commercial, industrial, and specialty applications such as boat construction.

My opinion here is I will NOT be using this with my aluminum boat. Just my two cents and I am no expert.

i emailed them about using their AC2 plywood in an aluminum boat for floor replacement and if it will react to the aluminum stringers. it will be interesting to see if they reply and what they have to say if they do reply.

I think that in all but the most severe circumstances ones decks are never fully immersed in standing water and that removing the boat from the water and pulling the plug or running the bilge pump on a regular basis could be considered adequate drainage.
