The closed-cell structure of extruded polystyrene (XPS) insulation offers excellent long-term strength. Its strength does not depend on the use of facers or lamination, making it a durable material for insulating walls.
XPS insulation also has good moisture resistance and can withstand high loads. The material is also environmentally friendly, since it uses a hydrocarbon instead of HFC blowing agents.
It is easy to install
Extruded polystyrene foam insulation (XPS) is easy to install and does not require any specialized equipment. In fact, it can be installed with standard fasteners and foam-safe adhesives, making it a cost-effective and easy option for insulating buildings. Unlike other types of insulation, XPS is not toxic and does not emit harmful volatile organic compounds.
Although XPS is a closed-cell material, it is not completely fire resistant. It is however modified with flame retardants to minimize its flammability and the spread of fire. It is still a good idea to block the EPS against sparks and dross when welding, or to pre-moisten it before proceeding with any procedure that could cause it to burn.
Moreover, it is durable and has a high compressive strength. It also resists moisture and retains its integrity in the face of extreme temperature changes, making it a great choice for building construction. In addition, it can be easily attached to a solid and dense vertical surface with special varieties of glue such as Penoplex FASTFIX, TechnoNIKOL or dilutable adhesive mixtures like Ceresit CT 83.
It is durable
EPS is a resilient construction material that can withstand the elements. It is a great choice for insulation in homes, commercial buildings and other applications. Its closed-cell structure makes it resistant to moisture, and a dependable long-term thermal insulation solution. Unlike other materials, expanded polystyrene is non-toxic and chemically inert. It also resists organic deterioration and does not attract pests like fungi.
Extruded polystyrene (XPS) is similar to EPS, but the main difference between them is their manufacturing process. XPS is produced through an extrusion process and produces closed-cell rigid insulation.
XPS is made from polystyrene resin with critical additives, which is melted together to form a thick liquid. The mixture is then pushed through a die and is expanded into a solid foam under controlled conditions. The result is a durable insulation board that’s resistant to water damage, mold and mildew. It also has an exceptional energy efficiency. It’s a great choice for a wide range of applications, including home insulation, cool rooms and refrigeration. It can even be used under concrete slabs.
It is environmentally friendly
Extruded polystyrene foam is a green product because it doesn’t pollute the environment when it’s used. This is because it doesn’t contaminate water or air and is non-toxic. It also doesn’t produce any airborne fibres and is unaffected by moisture. It is also highly insulating and does not lose its thermal performance over time.
Its manufacture uses steam and no chlorofluorocarbons, which have a negative impact on the atmosphere. Moreover, manufacturers recycle any scrap material and reuse it in production. This helps reduce waste and ensures maximum efficiency.
Polystyrene is also a more practical option than Styrofoam, which can be difficult to recycle and often ends up in landfills. Once it reaches landfills, it takes between 500 years and forever to break down. It can also be carried away by the wind and blown into waterways or oceans, contributing to the Great Pacific garbage patch – a flotilla of plastic twice the size of Texas.
It is affordable
EPS foam is inexpensive to produce, but it can be costly to dispose of. It is also difficult to recycle, because it contains many synthetic chemicals that can leach into waterways and soil. In addition, the manufacturing of EPS produces large amounts of greenhouse gases and liquid waste. To minimize this environmental impact, the company suggests that consumers use reusable plates, cups, and utensils.
Extruded (XPS) and expanded (EPS) polystyrene offer excellent thermal performance, moisture resistance, and durability, making them ideal for new construction and renovation projects. In this blog post, we compare the benefits of these two insulation materials to help you decide which is best for your home or commercial project.
Extruded polystyrene is a versatile, lightweight, and cost-effective insulation material that’s great for a wide range of applications. It’s commonly known as “Styrofoam,” but its uses extend far beyond the food packaging that bears the trademark name. It is also an excellent insulator for walls, roofs, cool rooms and refrigeration, and under concrete slabs.
