Atlas EnergyShield PRO exterior wall insulation and sheathing is composed of a Class A fire rated closed cell polyisocyanurate (polyiso) foam core faced with an embossed white acrylic-coated aluminum foil facer on the front and a reflective foil facer on the back. Common applications for this exterior wall insulation include placing it over existing cladding to improve energy efficiency and provide a level surface prior to installing new cladding. It is also known for its airtightness. This will helps ensure healthy indoor air, better thermal control, and more energy efficiency. Also, Atlas' exterior wall insulation can also be used for concrete wall systems or exterior sheathing for walls framed with wood or steel.
