Styrofoam™ Brand Square Edge Insulation* is an extruded polystyrene foam (XPS) insulation board that meets the needs of the commercial foundation and building floor slab market and can also be used for attics, foundations/slabs and crawl spaces in residential applications.
Is XPS foam a good insulator?
Both XPS and EPS provide good thermal conductivity performance. However, the air trapped in the voids in the EPS will conduct heat. A much higher density EPS board will be required to match the thermal performance of XPS insulation.
What is XPS insulation foam?
Extruded polystyrene (XPS) foam is 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.
Are polystyrene boards good for insulation?
Polystyrene is a material with uniformly small closed cells and a smooth skin which make it suitable for a wide range of demanding insulating applications.
Where would you use XPS insulation?
Manufacturers are now reporting the Long Term Thermal Resistance (LTTR) of their XPS products to account for the reduction in r-value over time. XPS provides increased stiffness and rigidity, making it suitable for use on roofs, below grade, below slab, and other applications.
Which foam board insulation is best?
Polyisocyanurate
Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation.
Is XPS foam board 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.
Does XPS insulation need 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.

How do you install XPS insulation?
Quote from the video:
Quote from Youtube video: Use a good drill with a hammering. Function at a concrete drill bit of the correct size for the concrete screws you're using drill a hole in each location you marked on the wall. Cut.
What is the R-value of XPS insulation?
FOAMULAR® 150 XPS insulation is classified as a Type X product when tested in accordance with ASTM C578 and provides a long-term thermal performance of R-5 per inch.
What is the difference between XPS and EPS foam?
XPS is manufactured in a continuous extrusion process that produces a closed cell form of foam insulation. EPS, on the other hand, is manufactured by expanding spherical beads in a mold and then using heat and pressure to fuse the beads together. Each product has proponents claiming one out performs the other.
Does foam board insulation need a vapor barrier?
Foam insulation usually does not require a vapor barrier. For some foam insulation types, such as closed-cell spray foam and foam board insulation, the insulation itself stops the movement of most water vapor.
How do you cut XPS foam?
Quote from the video:
Quote from Youtube video: But just with the two cuts that i made here go ahead and break. It. You can see it's a much much cleaner almost completely square cut that you have there because you're going.
Can you cut XPS foam with a hot wire?
Quote from the video:
Quote from Youtube video: It is pretty much impossible to cut this stuff with the hot wire foam factory. Table and it is quite tricky to cut it with a knife.
Can you sand XPS foam?
Use fine-grit sandpaper to perform finishing work on the foam, lightly sanding the surface smooth, or sanding into small detailed curves or edges that the coarser sandpaper or sanding block would otherwise remove.
What is the best way to cut rigid foam insulation?
Quote from the video:
Quote from Youtube video: Face down with the smooth back up take your measurement take a long utility knife blade extend the blade all the way out. And cut an aggressive angle straight through the product like this.
How do you cut a 2 inch rigid foam insulation?
Quote from the video:
Quote from Youtube video: If you need to cut rigid insulation you can use a utility knife.
Can you cut foam board with a jigsaw?
The S 155/W jigsaw blade is engineered to cut rigid foam and fiberglass insulation, cardboard, foam rubber, and similar materials up to 5 inches. The undulating blade is designed to give fast and clean cuts in materials that are normally processed with a box cutter or knife.
