Soo Confused about deck materials!!

12 years ago

I have been reading all the differents comments about Timbertech XLM/Azek/Correct Deck CX. The more I read the more confused I feel . It seems that all of these products have major flaws, that people are very unhappy 6 months after installation. Is it worth the expense or should I use the old treated ACQ wood?

I already have permits for my deck and find myself at a crossroad.

Thanks

There is no clear advantage to using composite over wood. Each person decides what values are important for their project: It may need to be: low cost, low maintenance, long lasting, light weight, extra strong, sustainable materials, or some combination of these values.

In my experience, wood beats out composite in every single area. Composites are heavy and flimsy. They sag. 12" joisting is required to exceed the minimum standards for residential building codes. All woods are lighter weight per span, with less deflection than composites.

The most common problem I've experienced with composites is deterioration. The way it deteriorates is worse than any wood; it's like wet particle board. They do tend to grow mold and mildew, but same for wood or anything outside.

A deck will last about as long as a car. Take a nice luxury car: If you garage it, wash and wax it frequently, keep up on the maintenance, it can last a lifetime. A piece of crap car will only last so long, no matter what you do. Some cars have a luxury name and price tag, but they are actually made the same as the econo-box cars. IMHO, composite deck materials are alot like that: An expensive name and price tag for particle-board material.

Western Red Cedar is considered one of the most sustainable and greenest building materials on earth. Read about British Columbia's Western Red Cedar industry.

I hope this helps answer some of your questions.

What flaws are you talking about?

When I built my deck I looked at XLM and CX - I liked CX a little better but a local lumber yard had XLM in stock at a good price so I went with that. Both are very hard and don't scratch easily. My deck is on the north side of the house and I didn't want any mold/mildew problems. I've been very happy with Timbertech XLM. Let me know if you have any specific questions.

Dennisgli:
I went to a deck magazine forum and noticed that regarding weight" For larger planters it will b eimportant to locate them in a way they lineup over the framing underneath...or sagging could occur overtime".
Anoter poster ( www.deckmastersli.com) discusses the issue of molding, staining, and the issue of weight issue. Granted these were older postings
On about.com a comparison of different products notes as the cons: issue of mold and mildew ( more in the shade), tends to sag and bends more than wood.
On a broadband report " wrenchnworks" writes that his TT " sunburns. Much of it has turned black and unsightly, some white...Only 1 1/2 yrs old. Deck was purchased about 8/2009"

THESE ARE THE THINGS I AM CONFUSED ABOUT WILL APPRECIATE CLARIFICATIONS IF CAN BE DONE.
Thanks

shinobu, we live in south lake tahoe, just completed a deck around 2 sides of our house. we replaced a redwood deck and then some, tore down substructure and started from the ground up. we researched all the usual suspects. we decided against trex for several reasons. several friends used trex, and within a couple of years had to replace decking, got involved in warrante issues, but trex eventually offered to replace material only. redwood was considered briefly,but decided against because existing was redwood and was only 15 years old. we decided to go with ipe, bought it in sacramento at berco redwood, paid 2.20 lf. they delivered. I built it myself, finished in october,berco replaced several sticks, probably my fault because wood sat outside for a while.I am waiting for warm weather to sand and seal,but it came out beautiful.we surface screwed, cleaned the snow off all winter. we plan to use tps 116 and see how much work it will be to maintain, if too much we will let it go to silver.part of the back deck is about a foot off the ground, good drainage underneath, runoff from the roof when snow melts not a problem. no mold, no cupping. bottom line epi a good choice. If your in the area, your welcome to come take a look at it. A bit of a learning curve, but it worked out well. one thing though, I originally got some bids from local contractors, most never heard of ipe, and the ones that did charged double the price to install.

When I was building my deck I narrowed down to TimberTech XLM and CorrectDeck CX. Similar products - I liked the look of the CorrectDeck a little better but I ended up going with the TimberTech because a local lumber yard stocked it at a reasonable price. It looks like CorrectDeck has been bought by GAF and CX is now DuraLife Siesta - so you might want to check that as an alternative.

Building new Ipe deck. Clips or no clips? (I'm so confused!)
Q
Comments (9)
Hi Oakrun, Yes, it is a daunting process. In fairness to all the homeowners here, (and respect to the pro deck builders who give so much help), we homeowners have pretty much one shot at the deck. In other words, we are not builders, and we are not Martha Stewart types, so we have to live with our decisions, warts and all. But on the other hand, we can afford to take a chance on something new. It will not wreck our livelyhood. I have nearly finished my 5/4" Ipe deck, 12' X 30'. After much thought, I went with the hidden fasteners - Tiger Claw TC-G http://www.deckfastener.com/products_tcg.asp They look great! Time will tell if they work. One difference between these clips and many of the old ones is that these are solid stainless, not fiberglass. To get these fasteners to bend would take quite a bit of force. I put one in a bench vise and hit it with a hammer. It didn't bend. One definite advantage of this system (assuming the boards don't lift) over face screwing, is the whole deck is "floating" on the pressure treated frame. The ipe boards are free to expand and contract slightly. In the long term, this may minimize end checking. Also, your air circulation under the deck seems optimal. (I have the same situation). I suspect that many installs of hidden fasteners don't have good air circulation. That may contribute to failure. Installation notes: 1) I used a biscuit joiner to slot the boards where the fasterers attach. It takes time, but I think it's a better job that having the boards slotted along the full length. 2) For butt joints, definitely ease the edges with an 1/8" radius. I think that's a John Hyatt trick. Looks great!! 3) I had to ease the backs of the ipe boards with a 1/4" radius router bit where the fastener attached. (the ipe comes with a 1/8" radius edge, not enough for correct installation) 4) most of the SS screws for this are # 8. If you are screwing into another hardwood (Ipe, Garapa, etc) I think the correct drill size is 9/64" . I broke a screw very early using the recommended 8/64" Here is a pic of a few weeks ago (I am doing most of this myself):

While as with all trees results are going to vary with site conditions Betula nigra is genetically a full sized tree - I think it is too large growing for the planting sites you are showing here. For example Seattle has one with an average crown spread of more than 62' (measured ~2005), with the largest known examples (elsewhere) being on the order of 120' tall with trunks about 5' thick. You do want something of some size to match the scale of the house but the magnolia will get big enough to do that if it does well. If it is not a superior named cultivar with a tall habit, fully evergreen foliage presentation (more than one example of these has been on the general market in recent years) I would replace it with one, as they are much more attractive than the shrubby, nearly deciduous version that drops all but one or a few leaves here and there. Another thing I would like to point out is that your house has a geometrically symmetric facade which means that this is one instance where a formal planting with matching pairs and shearing etc. is actually what is called for. A pattern mirroring the design of the front of the house on the ground in front of it and consisting of plants and other natural materials like stonework is what will best serve to integrate your house with the large lawn, which introduces a pastoral feeling. It would also be better to have the plantings extend out from the house more - and perhaps concentrate around the building less - even if the facade was not geometric.

The only thing that I might agree with is PVC decking may sag more that wood. So I wouldn't use it as a structural component to support a planter. And you could reduce the joist spacing from 16 to 12 if that was a concern. My deck does have some irregularity but I'm pretty sure that is due to the supporting structure being uneven - I had to use some complex framing including a 5x14 diagonal laminated beam that the decking sits on. You can see a little unevenness where the decking crosses the beam.

For the molding, mildew, staining, and sunburning - are you sure that those were Timbertech XLM and not some other Timbertech product? After a few years my deck was getting a little grungy looking - but it cleaned up easily with some deck cleaner and looks as good as new. I can't see that pressure treated pine would be anything but worse in these areas - but it would be cheaper I guess.

NO reason to shout Md.Decking is not a heartbeat ya know.

Manmade decking/railing is not a miracle drug, it is an ever changing material, each pron to some imperfect trait, some of those traits are termial some are just inconvenient,none of them are perfect, all of them have some Folks that are happy with them and hate them.

All ManMade will require cleaning ,like washing your car,many deck clearners will work on some of them some of them will not respond to cleaning at all to the degree of a new look.

I agree with Den, if you decide on a pvc type decking put the joists on at least 12'' centers less if your plan is to put it on the bias. PT pine is way cheeper in cost and quality.

TimberTech has earned a high rating in the Business over the years with customer realtions and quality product.They are quick to get into the latest high teck.

Another quality outfit is Moisture Shield an advanced and respected Co that has stayed with Composite and refined it to the point it can be installed in or under the water. Very good product.

Or,of course, you could go with South American decking and rail with alum balusters.

And be done with it.

Dear Aidan m, I am very sorry you could not follow my trend of thought. I do not think I am screaming, nor I intend to to confuse anyone. My confusion is that I noted that some of the composite materials including TT XLM tend to sag if weight is placed on them ( as noted by other forums and others members of this forum), they tend to grow mold/mildew, not sure what is the life span of these materials. They also are low maintenance. What would be the advantage of using these over wood? And by the way I can not use South american wood, etc..
