@homerenovisiondiy: One main difference between wood and composite decking is that composite doesn’t expand. Because of this you can achieve the perfect mitered corner to frame your deck. What do you think? Would you do this?

andreaterrymaine :

composites expand and contract like crazy. I have no idea what you're trying to say.

nothanks :

What brand of composite doesnt expand and contract? Trex, Azek, Timbertech, and every other brand Ive installed grows and shrinks with the temperature

tonyburg :

100% composite wood expands, and contracts

Frank & David :

The decking may not expand/contract but the deck its screwed to sure does, go look at any composite deck that is 5 plus years old and they alllllll look like trash 🫠

rusticstudio :

Doesn’t matter how good your tools are when you buy them. 9/10 times they gotta be tuned.

garretpatenaude :

composite does expand and contract by the way

johnbaxter455 :

I've done this. A sixteen foot composite board doesn't care how much glue or how many biscuits, that sh!t expands and contracts fast and a lot

yoshnet314 :

there is so much misinformation on the Internet. don't do this!

Retro_xennial :

ThatGingerGuy🇨🇦🔵🇨🇦🔵 :

So they don’t expand and contract. But put biscuits in so that they don’t?

anthonygibson810 :

joekool8 :

Greg Kelloway :

Bison1 :

composite lumber expands and contracts like crazy

Paul D1915 :

the majority of composites expand and contract more the traditional spf lumber

Mike Colp :

Did you not say it does not expand a contract but yet you said you put biscuits in so it doesn’t expand end contract

theangrynewfie :

Jeff Helmuth547 :

all manufacturer require gaps

Trapphau5🇨🇦 :

Should have used plastic biscuits though…

… :

Steel expands and contracts everything does

Cramer :

If it doesn’t expand or contract then why would you need to use biscuit joint to prevent it from expanding and contracting over time?

Tr33trunkfunk :

trex literally says they contract and expand...
