Spacer size for expansion joints

[mugentuner]

What do you guys think of using 3/8" spacers for expansion joints alongside a patio wall? Had a bag of them and figured they would allow for more movement with expansion/contraction. What do you think

Here is a quote out of the TCA Handbook:

Expansion Joint Width (Vertical & Horizontal)

• Exterior (all tile)—minimum 3/8" for joints 12' on center, minimum 1/2" for joints 16’ on center. Minimum widths must be increased 1/16" for each 15°F tile surface temperature change greater than 100°F between summer high and winter low. (Decks exposed to the sky in northern U.S.A. usually require 3/4"-wide joints on 12' centers.)

• Interior for quarry tile and paver tile—same as grout joint, but not less than 1/4".

• Interior for ceramic mosaic tile and glazed wall tile—preferred not less than 1/4", but never less than 1/8".

What's the difference between a term expansion joint and corner joint (where
2 walls meet for example). Are they the same thing?

Pretty much the same thing. Both are "movement joints."

Thank you.

Looks like I should be ok with the 3/8 spacers then. Thanks for the feedback
