R-Panels and Stucco

[mridgeelk]

This home has R-Panels for exterior walls with conventional stucco. The horizontal crack is where the walls meet the slab which has in-floor hydronic heat. This home is about 6500' above sealevel with temperature extremes 100 to -30 F. The south and west faces are as usual the worst. The amount of cracking seems high. Is this typical of R-Panels and stucco?

Hi,

If you're talking about SIPs walls, they're definitely wrong. The slab and the wall panels will move at different rates in response to temp/humidity changes. There needed to be a termination bead with weeps above the edge of that slab, as well as accessory and expansion joints at appropriate locations.
