XPS foam panel insulation, or extruded polystyrene foam, is a popular choice for insulation due to its high compressive strength, low moisture absorption, and thermal performance. There are several types of XPS foam panel insulation available, differentiated mainly by their compressive strength and density. Here are some common types:
-
Standard XPS foam: This is the most common type of XPS foam panel insulation, with a compressive strength ranging from 15 to 100 psi (pounds per square inch) and a density of around 1.5 to 2.0 pounds per cubic foot (pcf).
-
High-load XPS foam: This type of XPS foam has a higher compressive strength, typically ranging from 40 to 100 psi, making it suitable for applications where the insulation will be subjected to heavy loads, such as under concrete slabs.
-
Low-density XPS foam: This type of XPS foam has a lower density, typically around 0.9 to 1.25 pcf, making it lighter and more flexible than standard XPS foam. It is often used in applications where weight is a concern, such as in roofing insulation.
-
Ultra-low emissivity XPS foam: This type of XPS foam has a special coating that reduces its emissivity, or its ability to radiate heat, making it more energy efficient than standard XPS foam.
-
Flame-retardant XPS foam: Some XPS foam panels are treated with flame retardant additives to improve their fire resistance.
These are just a few examples of the types of XPS foam panel insulation available. The choice of insulation type depends on factors such as the application, required compressive strength, and thermal performance requirements.
