Xtreme Trim™ Panelcorner® Inside Corner

Prevents water penetration behind siding at inside corners, window boxouts, etc. Provides an excellent drainage plane not possible with usage of other corner alternatives to keep water out of the home, preventing mold/mildew problems.

Eliminates wood inside corner piece that will split/rot over time. With a wood inside corner, when caulk deteriorates and fails, water will enter and become trapped behind the siding, eventually rotting the wood piece requiring expensive removal of 50-year warranty fiber cement siding to replace.
