A wall is only as strong as its components. Atlas EnergyShield continuous wall insulation boards are not only proven to improve thermal management performance, but they are also designed to work together with the wall assembly products required for the job. With more than 30 years experience in polyiso manufacturing, Atlas has the expertise to create innovative products that will reduce costs and installation time. That’s why Atlas EnergyShield products have water resistance built in, so you can seal the building like a housewrap or other WRB, but with the added value of insulation. There’s no need for an extra trip around the building to put in a separate WRB, so you’ll save time and money with the installation of just one product.

We have a variety of resources at your disposal to help you find the right Atlas product for your job – and ensure those products are installed the right way, the first time.

Atlas has the highest R-value, one-step polyiso rigid wall insulation available. Our uniform production methods ensure quality control for more precise applications and more consistent thermal performance. From built-in water resistive barriers to sheathing that doesn’t require taping, Atlas EnergyShield products are designed to perform efficiently and cost effectively
