Hello wood and building and construction experts: My outdoor deck project in coastal Massachusetts has required a very sturdy treated SYP 2 x 12 floor frame together with treated 4 x 12 parallams.
To these framing components will be nailed either fir or mahogany decking. Is there a benefit to metal flashing, or felting the tops of
framing members before installing the deck boards? I’ll forever be in the debt of those suggesting why or why not this should be considered.

You might want to check out the viability of using Paralams outdoors. They don't tolerate the wet at all and will lose their engineered strength values and the mfg. warrantee.
He did say he was using treated parallams.
Trus Joist MacMillan has Wolmanized Parallams. 30 year guarantee against manufacturing defects, termites and rot.
Too much in the way of paint fumes today...I missed that treated part and stand corrected.
Not too many fumes out on the Cape. That hurrican ecleanned them all out.
It would be a good idea to at least seal the top of the lam with paint because the edges are still open to water and there is a wicked freeze-thaw thing that goes on there with plenty of moisture to split edges when water gets in and freezes..

Not to stray off the subject here, but I took a truck out of Gorhan, NH Sept. 11. It was 85 and raining. When I climbed the hill out of town, the wind hit; the remainder of the hurricane that had hit Texas that week. 'Bout blew me off the road and I had heavy wind clear to Syracuse.
It's a regional thing, I guess, but out here in the NW we get no effect from the hurricanes and it was, by me anyway, totally unexpected.
Another long treatise lost to cyberspace.
Ahem...I hit the wrong button.
No need to use paper flashing for treated SYP it will cause rot of deckl boards by holding water to the backside.

Jim,
Just hold tight....I`ll be up in Dennisport, Columbus Day weekend, we`ll knock it off over some quohogs and chowder. You got room for my wife and four kids?
