anyone know anything about this stuff? i am having someone install new construction windows on an english tudor style home and the sub mentioned the outside trim will have to be ripped off and replaced with AZAC board.
never heard of it. is it expensive ? just need to trim one window.

Azek is one name brand of composite material.Tanza and Fiberon are others. I have used it plenty. No real complaints except the price and very flimsy to transport. Cost is often a factor to customer but when told they will never have to replace it seems to justify itself. It does work like wood but can be a little finicky especially in cold weather. Manufacturer also recomends using their glue for seams & miters etc. but I have found that a good PVC pipe glue (1/2 the price of the name brand) works just as well. Give it a try you make the decision.

Koma, Azek, Kleer, NeverRot and Royal Board are some more. Like G said, it's really floppy so you'll need a strongback to transport it. Koma has a brushed appearance that is a magnet for dirt, especially if you're handling it with dirty hands or gloves. Clean it with 409 or something similar. Azek has a more glossy twin finish, smooth one side, cedar wood grain on the other. With it's glossier finish it's easier to wipe clean. Keep in mind that all PVC expands quite a bit in the heat. It's not uncommon for a full length installed in the winter to expand by up to 3/8" in the heat of summer. This causes even glued joints to blow apart. I've seen it myself, even with Christy's White Hot Glue. I would not use pipe glue. I've heard good things about Bond 'N Fill glue, it's supposed to keep that from happening. Be careful when handling pieces with mitered cuts, they can be REALLY sharp!:cry:

Very true! I learned the later the hard way. Then 409 is a must to get the "red out" OUCH!:w00t:

What do you guys use for nail filler. Ive seen a TON of botched jobs do to caulking and nail hole filling, all turning yellow the next year. I can show you pictures of many high $$$$ homes near me that look like crap now cause of this

What gun are you using?

ya, but what fills the hole? Even the finish gun inevitable leaves that little rectangular divit which is noticeable at least to me
My cheap Smith and Wesson doesn't leave a rectangular hole. The hole is no larger than a regular (hand nail) 6d finish nail would be. The Hitatchi however leaves too big of a divit.

Great upper end product IMO. It is pricey compared to wood, but that is totally insignificant, since you are only talking about one window. Agree with the others, that long lengths tend to be annoying to work with because they are so flexible. We install with 15 ga Hitachi gun, be sure to use stainless nails. Anything that could get knocked (like window sills) get backed up with ss trim head screws. IMO Azeck and Kleer are the two best brands, because they are more consistently solid in the core and leave a much more workable edge when cut or profiled, the others tend to be much rougher to me. Also, some of the less expensive products have a very brittle outer shell and seem to crack or shatter a lot when nailed. Like everything, you get what you pay for. Although we caulk with high performance selants like Lexal or Geoseal, we find that using it to fill nail holes is too messy. Since our applications are always painted, our painters use exterior grade of painters puttty. Everyting then gets primed with a xylene based primer, and topcoated with top of the line acrylic. I love the product, but for it to look convincing as a wood substitute, it has to be painted for me.
