According to a recent press release by EPA's Energy Star arm—in 2003, ENERGY STAR helped Americans save enough energy to power 20 million homes, reducing emissions equivalent to that of 18 million cars..

Extruded polystyrene foam is the best insulation you can choose when it comes to resisting water moisture absorption. Without the need for a facer or laminate, XPS products only absorb 0.3% by weight.

With growing concerns about the threat of global climate change, it’s important to look at various sustainable materials to see how they interact with the environment.


Did you know?


Insulating sheathings like XPS not only add significant R-value to wall systems, they also reduce air leakage.

XPS is manufactured from polystyrene resin, a thermoplastic material, which can be melted and re-inserted into the manufacturing process to produce new XPS insulation - creating virtually no ‘scrap’ or waste material.

The International Code Council (ICC) Building Code and the ASCE 32-01 Standard recognize that XPS performs better than EPS in below-ground applications.
