What does XPS stand for foam?
Extruded polystyrene insulation
Extruded polystyrene insulation (XPS) is manufactured using a process of extrusion. This continuous process results in a closed cell structure with a smooth skin on the top and bottom of the board.
What is XPS foam made of?
XPS foam board is a rigid thermoplastic material manufactured from polystyrene. Polystyrene is a synthetic, hydrocarbon polymer derived from benzene and ethylene, two petroleum products.
What is XPS insulation made of?
Extruded polystyrene (XPS) foam is a rigid insulation that’s also formed with polystyrene polymer, but manufactured using an extrusion process, and is often manufactured with a distinctive color to identify product brand.
What is XPS made of?
Is XPS the same as EPS?
EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins and manufactured differently, EPS is beads that are molded or cut into various sizes and shapes while XPS is extruded sheets.
How strong is XPS foam?
Products are available in a range of compressive strengths to meet different applications. XPS foam board can be manufactured up to 100 psi or more.
Is XPS foam plastic?
What is Extruded Polystyrene or XPS Polystyrene Foam? Extruded Polystyrene (XPS), is manufactured via an extrusion process where plastic resin and other additives are combined and extruded through a die. The extruded foam then cools and expands into it’s final shape.
Is XPS a vapor barrier?
XPS is manufactured in both an unfaced form or with different plastic facings. However, XPS is considered a vapor retarder, not a vapor barrier.
Is XPS foam toxic?
Most rigid polystyrene foam insulation boards, both the EPS and XPS types, contain the toxic flame retardant HBCD, which was banned by the European Union in 2015.
Is XPS foam waterproof?
Technically, EPS and XPS rigid foam board insulation are considered to be water-resistant. A product branded as waterproof means that it offers complete impermeability, even if permanently immersed in water.
What is XPS polystyrene used in?
Extruded Polystyrene Board is ideal for a range of uses – from wall and ceiling insulation, cool rooms & refrigeration, under concrete slab (i.e. car park), and even for architectural modelling or hobby model making. Extruded Polystyrene is the ideal insulation material for houses and commercial applications.
What is the difference between EPS and Styrofoam?
The word Styrofoam™ is often used to describe expanded polystyrene (EPS) foam; however, ‘Styrofoam’ is actually a trademarked term for closed-cell extruded polystyrene foam made for thermal insulation and craft applications. EPS foam is the correct term for any form of expanded polystyrene.
