What is extruded polystyrene (XPS)? 

Also known as XPS polystyrene foam, XPS is a popular thermal insulation that supports heavy loads without deforming or breaking. It has a higher compressive strength compared to EPS. 

What is the lifespan of extruded polystyrene? 

XPS insulation or extruded polystyrene has a life expectancy of 20 to 30+ years with proper installation and maintenance. Its durable nature ensures continued thermal protection and energy savings against temperature variations and weather conditions. 

Can extruded polystyrene get wet? 

It has superior moisture resistance compared to EPS. Its closed-cell structure makes it highly resistant to water absorption while retaining its performance. 

What are the benefits of extruded polystyrene? 

Extruded polystyrene (XPS) foam boards are a top choice if you’re seeking superior insulation for your building projects. These boards outperform others thanks to their higher R-values, meaning they’re better at keeping heat in or out, making your space more energy efficient. Additionally, XPS boards are highly resistant to water damage and rot, making them durable even in wet conditions.
