My first experience with a composite deck. Tore up the old cedar deck and cantilevered new joists to make it four feet bigger.
KennMacMoragh said:I don't think so because there's flashing and silicone covering it. The glass supplier gives you the mortar to use. They don't call it mortar, the call it something else that I can't remember. But they explained to me what it was, and it's the same thing as mortar. It's a finer granule cement, I think a type III cement is all it is. They don't mention epoxy, my guess is it would be too thick and wouldn't fill in all the gaps right. With the mortar, you set the glass in first, get everything aligned the way you want it, then pour in the mortar and it fills in all around it. Here is a picture of the outside. The brown is flashing covering the aluminum channel.
It's not a code requirement, I put it on the doublers so water doesn't get between them. Even when I tore up this deck, where ever there was two members nailed together, the treated wood was rotted and falling apart.Is the Vycor on the joists required or do you just do that for extra protection?
