Whats good to protect a deck from heat.
 
Since, we had a little, but very dangerous burn through on our deck from a UDS, not being properly closed off at a end of a smoke(not myself).

I was looking at getting .5 to 5/8 Cement board and then tiling it with a outdoor tile and then putting the UDS on top while still using fire bricks to keep an air gap between the UDS and the tile.

Would this work or is there a better alternative besides moving the UDS off the Deck.

That would work, and sounds like a lot of work too.
How about using an oil drip pan from the auto parts store, on top of bricks, below your fire bricks below your UDS?

Top to bottom:
UDS lid
UDS
fire bricks (air gap)
oil drip pan
fire bricks (air gap)
deck

?

The tile might look nice at the outset, but they wouldn't last if adhered to cement board in the way you describe.

Just raise it up a few inches on some bricks or other non combustible material. Enough so air can flow freely underneath it.

I say tile should work well

Here's a list of fireplace hearth material R values. Just so you have an idea of what the insulating values are. Cement board is on there as well as tile.

I use a leftover piece of tile cement board just to keep under my chimney starter to keep from scorching my driveway when I use it. I've not tried it on wood decking before, but I'd think it would suffice. The stuff comes in a 3'x5' sheet, so you could cut it in half and double it up too, just to be safe.

Mine's lasted for 4 years now through rain and all and is still holding up OK.


I don't disagree with the metal oil drip pan idea either, though as suggested by otterpop. It'll definitely last longer.

If I recall, you're in a rental home, right? You roommate with "The Drunk"? I think I'd use one of these simple solutions instead of tiling somehing up that would be cracked when trying to move around.

I am a Tile Contractor ah finally a tile question :-P

The tile with the cement board would work fine but the most important is the air space. If you can do this the tile isn't necessary

UDS / airspace / shield of some kind / airspace / deck

The airspaces only need to be a couple of inches.
The shield could even be a drum lid

Yeah, I was planning on still using the fire bricks(stove bricks) under the UDS for air movement, and then the tile and grout, cement board.

I had the UDS on the fire brick, just like these

and needless to say we now have a hole in the back deck.

I know with proper use of the UDS, i would not have a problem with just continuing to use the fire bricks but to have a sense of safety if my roommate decides to try and use it, even after he has been banned from bbq'ing again, lol. I figured i would add a another safety barrier and something that will cover up the new wood that wil be replacing the burned wood.

Buy a stove board

Protect a deck from heat? I was gonna say shade, but I see you have bigger problems.

Patio tiles/stones 16" x 16" or one 30" x 30" stone from Lowes or HD, fire brick above that (I have a metal dolly for my UDS but I have a stone patio. I use an extra stone for my chimney

If you get a piece of cement board and tile over it, you should have fire protection and good looks. Perhaps some molding around the perimeter too.

Be sure the cement board is exterior rated. I'd go the 1/2" thickness to boot.
