Tiger Deck owner/installer here, over 750 sq ft of it. 12 x 50 foot, then a middle dog leg deck around a hot tub. Put it down 10 years ago.
I love it dearly.
lives in damp Seattle Mountain weather, but full southern sun exposure. no moss or mildew problem on hardwood, cedar decks last maybe 10 years here.
I'd do it again in a heart beat. I also did slick alum T star screws and hidden fasteners biscuited into the sides
some Tigerdeck comes with a pre-routered groove.
I put it in a herringbone style, wood has weathered excellent over 10+ years, with SuperDeck Hardwood stain every couple years. After the first 5-6 coats, I've not needed it as often.
Trex and other composites, no way, thermal issues and icky tacky factor.
My TigerDeck was Cashew Wood, also known as zebra wood, from Honduras or Brazil. It's incredible dense and hard/heavy. This wood is CLEAR, zero knots, not a one. no "tight knot" with round holes/plugs ever couple feet..........
I put down 5/4" x 6. True 1" thick.
It Hasn't cupped or warped at all, even with hidden fasteners. not some wimpy 1/2" x 4 (though in tigerdeck, that's still about the strength factor of a pine 2x4) . On my herringbone too, I was spanning about 18" over the Joists. No I'm not anall............but I even painted the tops of the floor joints black so I wouldn't see them through the 1/8" gap.
IPE, is just another brand name for a Hardwood, so make sure you know your species, and what you're getting.
I got mine from an independent lumber yard, but you used to be able to special order Tigerdeck from HomeDepot.
Here is the deck from 10 years ago new construction in 2006.
If someone wants a scrap sample of the hardwood, I'll send you a hunk, pm me.
As I said, pay postage and you'll free samples of my scraps, and any questions let me know.....zero regrets on the tigerdeck.
it's gorgeous. I'll post some "after 10 year photos" soon.
