What does XPS stand for foam?
Extruded polystyrene insulation
Extruded polystyrene insulation or XPS Insulation is manufactured through an extrusion process. This manufacturing process involves melting together the plastic resin and other ingredients. The liquid formed is then continuously extruded through a die and expands during the cooling process.
Is XPS high density foam?
When insulation comes into contact with water it can have an adverse effect on its ability to thermally insulate; but when faced with extreme weather conditions, Styroboard XPS still preserves its thermal and physical properties thanks to its high-density cell structure, making it practically impervious to water.
Is XPS foam waterproof?
XPS. XPS is another waterproof, rigid insulation material. The final product is rigid, dense and waterproof. As a result, XPS is commonly used for roofing and below grade to insulate cement slabs and foundation walls.
At what temperature does XPS foam melt?
This means that XPS is less rigid and can become pliable when exposed to a temperature of about 165 degrees Fahrenheit. XPS insulation meets its melting point typically between 200 degrees and 210 degrees Fahrenheit.
Is XPS foam toxic?
Halogenated flame retardants like HBCD are substances of global concern; they are among the most toxic, persistent, and bio-accumulative substances used in building products. Typically, XPS insulation contains about 0.7% HBCD flame retardant by weight.
Is Foamular a vapor barrier?
An insulating sheathing keeps the wall stud cavity warmer. Warmer air and surfaces are less likely to experience condensation than colder air/surfaces at any given level of humidity. So, FOAMULAR® insulating sheathing, that is also semi-permeable, is not a “double vapor retarder” concern.
Is EPS better than XPS?
XPS, at about R-5 per 25 mm, has only a slightly better thermal performance than EPS. The thermal insulation performance of EPS and XPS in identical densities is quite close. However, EPS with the same level of density is less expensive.
Is XPS stronger than EPS?
Is XPS foam soundproof?
When polystyrene is expanded into a foam material it is called Expanded Polystyrene (EPS) or Extruded Polystyrene (XPS). In its expanded form, polystyrene has low thermal conductivity which makes it a great insulator.
Is XPS an air barrier?
At 1 inch or less, XPS is a Class III vapor retarder, qualifying it as a permeable material. In this instance, the air barrier of choice is would also be permeable. Material properties such as air and water vapor permeance can change over time.
