JM CI Max Sheathing

Please call 1-877-944-7697 for price and availability

Product Description

Johns Manville CI Max™ foam sheathing board is designed for exposed interior use, made from a uniform closed-cell polyisocyanurate foam core bonded on each side to a printed foil and glass mat facer.

Performance Advantages:

• Thermal efficiency – polyisocyanurate foam provides a high degree of insulation efficiency, resisting heat transfer with R-values up to R-25 (RSI-4.40 at 4" thick). It reduces thermal bridging at framing members, improving the overall thermal efficiency of walls.

• Noncorrosive – does not accelerate corrosion of pipes, wiring
  or metal studs.

• Lightweight – easy to handle, can be cut with a utility knife or saw.
