A Wall Insulation Board Suited for Commercial or Residential Applications

Atlas EnergyShield® rigid wall insulation is a closed cell polyisocyanurate (polyiso) foam core, faced with a reflective foil facer on the front and a non-reflective, red acrylic-coated facer on the back. Insulated walls with EnergyShield® combine high R-value, durable foil facers, and water resistive attributes in a high performance rigid insulation board. EnergyShield® wall insulation is suitable for a variety of continuous insulation (CI) applications.

Wall insulation panel sizes are 4' by 8' or 4' by 9'. Insulation panels can be supplied in nominal 16" or 24" widths for use in cavity wall applications. Custom sizes are also available.

Atlas EnergyShield® has multiple practical applications from exterior or interior insulated (with a thermal barrier) sheathing to attics and crawlspaces without requiring the use of a thermal barrier. And it is a perfect fit for use over existing cladding to improve energy efficiency and provide a level surface prior to installing a new cladding, and so much more. Contact your Atlas region sales rep for more information on what Atlas EnergyShield® can do for you.

R-values: EnergyShield®

Insulation R-value is a measure of thermal resistance used in the building and construction industry. The R-value being discussed is the unit thermal resistance. This is used for a unit value of any particular material. Below is the table of insulation R-value for Atlas EnergyShield® wall insulation. The higher the number, the better the building insulation's effectiveness.

1    Conditioned thermal values were determined by ASTM Test Method C 518 at 75° mean temperature.
Test specimens were conditioned in accordance with procedures outlined in ASTM C1289, Section
2    “R” means resistance to heat flow. The higher the R-value, the greater the insulating power.
