Imus Seal Butyl Joist Tape used as barrier between metal joist hangers and pressure treated wood

Provides a Barrier Between Metal and Wood

Corrosive chemicals like alkaline copper quaternary (ACQ) and copper azole (CA), commonly used in pressure-treated wood, can corrode steel joist hangers and other metal hardware. Installing Imus Seal Butyl Joist Tape between metal and wood creates a barrier to prevent contact.
