Second & 3rd story deck ?

Hi getting plans together for two decks, the first level deck will be 10' above ground level. The size is 10' x 20'
Access will be off the second floor game room.

however the home will be built with SIPS (structural insulated panels) so there are no beams or sill plates etc to tie into in the walls.

I can mount a 2by ledger on the exterior and 3/4 ply on the interior to tie the ledger in.

I was planning on using 6x6 posts on concrete piers, so this level would have 10' tall posts.

next directly above this deck a 3rd level is planned 10'x10'
Same ledger system

Not sure how to construct the posts for the3rd level

one option I was thinking of was use 8x8 post 18' tall, notch in the 2nd floor beams and mount the 3rd level beams on top of that post.

I read something about a 14' max height on posts????

Second idea, mount a 6x6 x 8' post directly on the second level deck etc.

I hope I explained the plan enough.

No batteries, Tesla's are great for off grid, but they are very pricey, when they drop in price for folks going off grid they will be the standard.

Today with net metering in most states and 30% tax credit its a big biz esp in NY & CA. Nice seeing a meter go backwards :thumbup:

This build is being design as a "net zero" passive home, in fact there will not be any need for heat, but building code requires it and A/C will be nice from time time.

A 9,000 mini split will be over sized in this 1550' 1.5 story design

A 4K grid tied array will be installed and all excess will be sold back to GA power at about .13

The purpose of this high deck is the mountain views are great.

No wonder my customers think it looks horrible. Can't stand the look of MS. It's as pretty as Evergrain that I have to use on mobilehomes. I tried to sell it but my customers were completely turned off by it once they saw the capstock out there.

I think Jimbo's tripping over dollars to pick up dimes. If he's doing the whole house there's tens of thousands at a minimum involved and as SFO pointed out, an engineer could offer some good advice for a few hundred bucks.

The money saved is not worth the headache of wondering 'Did I do it right?' and the liability if it goes south.

All their trucks are bio diesel as well. They have no smoke stacks in their plant. It's by choice too .The Government isn't mandating them or subsidizing. Agree with it or not it's what they choose to do.
It's a great example of allowing profit to be made with the green movement. It's the only way it will work long term in this country.

If they power up the heat with electrical there would be no " smoke stacks " like they were burning coal or the like. Same with natural gas in the true sense but the heat has to be vented through something to somewhere .

Interesting read on seed based hydraulic fluid. Trex buddies at Exxon are into it, what a surprise !, still it was a new concept to Me. It's not a direct replacement for several reasons but still has it's place and is good PR.

Thanks !!!

Not true, if mobile sold the company that then became Trex how could it be that Exxon was ever Trex?

Roger Wittenberg combined sawdust and plastic bags to create park benches and, later, decking[4]1996Mobil Chemical Co. acquired Wittenberg’s technology and later that same year Trex Company LLC was formed after a buyout of the Mobil division that owned the technology[4]

Mobile was NEVER TREX it just owned the technology that was bought by a company named Trex.



If you knew anything about buying companies (or technology) you would understand that you not only get the assets you also have to take the liabilities. Fortunately a jury found all claims against Trex and patent infringements to be false.

Here's the first paragraph. It only proves my point.

In this diversity declaratory judgment action, the parties to a transaction involving the sale of a business dispute whether a particular patent infringement suit is a liability retained by the seller or one assumed by the purchaser

3rd story deck as per se a deck is off the build,

figured a way to make a 3rd story deck out a flat roof,
this will join the 2nd story deck via a stair.

It looks a hell of a lot better.

the SIPS deck ledger is built by placing a 2 by on the outside and another on the inside wall (6 1/5 " thick) thru bolted or lags.

Actually it does, but the way it has to be done is ridiculous. Lags don't count. Only through bolts. The whole can be no bigger than the bolt (5/8" most likely) but cannot tear out any material in the process of putting it in, did I mention it has to be plumb and level? 1/16" either way in 1':rolleyes: Not to mention it has to be a nylock nut or a split washer on another washer with the main washer being like 7 times the size of the width of the bolt (or something like that).

This is how it was explained to me by an architect down here who is really good but really anal on facts. So I said, "so we should come up with a different way". And we prceeded to bicker like a couple of old hens for a wasted hour.

Here's a short article on 2nd floor framing and SIPs................

Second floor options and sealing rim joists

The standard technique to second floor framing in many SIP two-story houses is the conventional approach: place floor joists and a rim along the top of SIP walls and then deck them over, per standard platform framing. This works okay. However, realize you then need to air-seal and insulate the rim system carefully or it will be just as leaky as it is in standard 2x construction. Furthermore, in cold climates you should apply an air barrier on the inside of the insulation (inside each floor joist cavity) in order to prevent migration of water vapor through the insulation and out to the cold rim where it can condense and cause cosmetic and structural problems such as peeling paint and rot.

The best way to achieve this insulation/air barrier system at the rim is to spray at least one inch of expansive urethane foam against the inside of the rim joist. In fact, you should do this around the basement rim as well (unless you're using a SIP floor over a crawl space). You don't need to hire someone to spray this foam; you can purchase a large foam pack with two-part urethane that can be applied by anyone who understands the concept behind your air barrier system. The foam might cost $200 or more per house.

For the second floor of a two-story, here's a viable alternative: order 10-foot tall wall panels and hang your second floor off the top plate with top-flange joist hangers. This provides you with an insulated rim-the panel-and makes it a snap to air-seal this traditionally leaky site. If you can install a continuous I-joist material from one side to the other-with or without mid-span support-this approach also provides an elegant way to stiffen your entire structure. However, it also requires a little extra planning when it comes to wiring your second floor. (See "Wiring" section.)
