Latest Technological Advancements in Extruded Polystyrene Products
When it comes to insulation, builders and developers have a variety of materials to choose from, including fiberglass, expanded polystyrene (EPS), polyurethane foam, mineral wool, and extruded polystyrene (XPS). While each option has unique strengths, extruded polystyrene stands out for its balance of performance, durability, and cost-effectiveness. A closer comparison reveals why XPS is often preferred in projects requiring long-term efficiency and resilience.
One of the most significant differences lies in thermal resistance. Fiberglass insulation is widely available and inexpensive, but its R-value can diminish when exposed to moisture. In contrast, XPS maintains a high R-value over time, even in damp conditions, due to its closed-cell structure. This makes it particularly effective for below-grade insulation in basements and foundations where other materials may fail.
When compared to EPS, XPS offers greater compressive strength and moisture resistance. Although EPS may be more affordable, it is less durable under pressure and prone to absorbing…
