Rmax Vented Nailable Base-3
Straight-Line Venting Insulation for Above the Deck
Vented Nailable Base-3 is a composite panel with glass fiber/organic mat faced polyiso insulation bonded to furring strips and a 7/16” OSB nailing surface. The solid wood furring strips come in 3/4” to 2” thicknesses for straight-line venting from the soffit to the ridge.
This product is great for preventing heat build-up and helps remove moisture as airflow is provided under the OSB and shingles.
