Multi-Vent Nailable Base-3

Multi-Directional Venting Insulation for Above the Deck

This energy-efficient composite insulation utilizes solid wood vent blocks to separate the rigid insulation layer from the standard 7/16” OSB nailing surface. The insulation has glass fiber/organic mat facers on both sides. The solid wood vent blocks come in 3/4” to 2” thicknesses to meet enhanced multi-directional venting requirements.

Superior for use in commercial steep slope roofing applications.
