It is especially efficient as a component over cathedral ceilings in log homes, conventional housing, churches and athletic auditoriums. Additionally, ACFoam Nail Base Insulation may be installed under metal roof systems and over metal decks minimum 22 gauge or heavier. This product should be used only in strict accordance with Atlas recommended uses and application instructions. Atlas recommends the use of vapor retarder for all projects except in extreme cooling climates.
