Investing in energy efficient building products like continuous wall insulation can result in major cost savings over the service life of a building. Industry experts have proven conclusively that exterior continuous insulation is the most effective way to insulate building envelopes for energy – and financial – savings. Atlas EnergyShield® continuous wall insulation boards are made with a polyiso core, which achieves a higher effective R-value (the capacity to resist heat flow) with minimal material thickness. This thin board allows for a more efficient and rigid wall assembly, ensuring both short and long-term savings.

There are several other benefits to polyiso wall insulation. Check out the quick links below to learn more about continuous insulation and the Atlas difference.

Still wondering about polyiso? Polyiso can be installed in attics and basements without the need for a thermal barrier, meaning walls insulated with Atlas EnergyShield products can be installed without the cost of additional layers. In fire testing, polyiso chars in place and doesn’t melt or drip like other foam plastics. Other benefits and differentiators you’ll experience when choosing Atlas EnergyShield include:


  • Highest R-value per inch of any insulation
  • Provides thermal, moisture and vapor resistance in a single layer
  • Suitable for new construction or retrofit
