Extruded Polystyrene Board

Extruded Polystyrene (XPS) Rigid Insulation Board is a high-performance, durable thermal insulation material widely used in construction and industrial applications. Made from polystyrene foam, XPS boards are characterized by their closed-cell structure, which gives them excellent thermal insulation properties and resilience under various environmental conditions.


SOHO Extruded Polystyrene Rigid Insulation Board combines superior insulation properties with high durability and moisture resistance, making it an ideal choice for a variety of thermal insulation needs in construction, infrastructure, and industrial applications. Additionally, our Extruded Polystyrene (XPS) Rigid Insulation Board incorporates Low Internal Stress Technology, a proprietary innovation that significantly enhances the material's performance, stability, and durability. Our extruded polystyrene insulation board offers enhanced dimensional stability, a lower thermal conductivity coefficient, and exceptional pressure resistance. It is also non-toxic, eco-friendly, and fully aligned with green building standards. Contact us now and get more details!

FAQs of Extruded Polystyrene Board

Can extruded polystyrene boards be recycled?
Can extruded polystyrene boards be recycled?

While XPS extruded insulation board is not widely recycled, some facilities accept it for recycling. However, it is best to check with local recycling centers for specific guidelines.

How do XPS boards compare to other insulation materials?
How do XPS boards compare to other insulation materials?

Compared to other insulation materials, XPS offers a higher R-value per inch, better moisture resistance, and is less prone to damage from pests or moisture compared to fiberglass or cellulose.

Can XPS extruded polystyrene boards be used in outdoor applications?
Can XPS extruded polystyrene boards be used in outdoor applications?

Yes, extruded polystyrene boards are suitable for outdoor applications, especially below grade or as part of a waterproofing system due to their resistance to moisture.

Where can I get material safety data sheets (SDS) for SOHO Brand Extruded Polystyrene (XPS) Insulation Board products?
Where can I get material safety data sheets (SDS) for SOHO Brand Extruded Polystyrene (XPS) Insulation Board products?

Extruded Polystyrene (XPS) Insulation Board products are globally defined as articles, which do not require Safety Data Sheets according to chemical laws in the following:

  • United States

  • Canada

  • European Union (EU) and other Europe/Middle East/African (EMEA) countries

  • Asia Pacific countries (including Australia, China, Japan, South Korea, Thailand, etc.)

The XPS Board listed does not release or otherwise result in exposure to a hazardous chemical under the intended conditions of use and meet all other listed requirements of an article. Therefore, these products meet the global definitions of articles which do not require SDS creation or distribution.


Are SOHO rigid foam insulation considered to be Class A foams?
Are SOHO rigid foam insulation considered to be Class A foams?

Section 803.1.2 of the 2021 International Building Code (IBC) specifies Class A, Class B, and Class C requirements.  Although insulation materials can be used as a finish material or as a material imbedded in the wall assembly, this classification scheme can be used to describe the basic classification of the fire properties of foam plastic insulation.  Our rigid foam insulation boards belong to Class B.
