Everything you need to know about Extruded Polystyrene Insulation – XPS
What is extruded polystyrene insulation made of?
Extruded Polystyrene (XPS) is a type of foam insulation material made from polystyrene beads that are melted and extruded into board-like form. XPS is known for its high insulation value, durability, and moisture resistance, making it a popular choice for use in construction and building insulation. XPS is also used in various other applications, including packaging, cushioning, and custom molding.
With its extruded polystyrene (XPS) construction, this board does not absorb water, is not a food source for mold, and is not subject to moisture-related damage and deterioration. An R-Value of 5.0 per inch of thickness makes it an excellent thermal insulator that increases the energy efficiency of your structures. The board also provides an extra barrier against moisture infiltration. XPS is available with square edge and an interlocking shiplap edge that helps reduce energy-robbing air leaks at seams and gaps.
What is extruded polystyrene insulation used for?
XPS Insulation Board is ideal for a variety of applications in walls, roofs, and foundations, including below slab, below grade, inside basement walls, and exterior insulation over wood sheathing.
Like many construction materials, XPS insulation is combustible and may constitute a fire hazard if improperly installed. These products should not be left exposed in the interiors of buildings where people reside, work or assemble. An approved thermal barrier, such as gypsum board or its equivalent, should be mechanically attached over the foam in interior applications. Recommendations of fire and building codes should always be followed.
The uniquely resistant and durable qualities, inherent to extruded polystyrene foam, make XPS one of the most dependable long-term insulation materials available.
Is extruded polystyrene insulation toxic?
Extruded polystyrene (XPS) insulation is considered to be safe and non-toxic. XPS is made from polystyrene beads that are melted and then molded into foam board insulation. The manufacturing process does not use any harmful chemicals, and the finished product does not contain any volatile organic compounds (VOCs) that could be toxic to humans or the environment. The products of XPS combustion are toxic, however, thus XPS should always be installed with an approved thermal barrier to protect it from fire.
The price of extruded polystyrene (XPS)
The price of extruded polystyrene (XPS) can vary greatly depending on the location, the size of the order, and the quality of the product. As a rough estimate, the cost of XPS can range from $0.50 to $1.50 per square foot. However, prices may be lower or higher depending on the specific circumstances.

Is XPS green?
XPS insulation has a high R-value, which means it provides excellent insulation and reduces the need for heating and cooling, leading to energy savings and reduced carbon emissions. Additionally, XPS is a low-emitting material and does not contain harmful substances such as formaldehyde.
At Green Insulation Group our mantra is “reduce, reuse, recycle”. One of our specialties is the distribution of XPS insulation that can be reused. Save money, lower your heating bills, and keep XPS out of landfills.
