Questions & Answers

can this be used under mobile homes

can this be used under mobile homes
Asked by: gallon
Yes. It's easy to install. Trim as needed. You can double or triple it up for even higher R value depending on your needs.

Type of Polystyrene

Is this considered “extruded polystyrene" or "expanded polystyrene"?
Asked by: NickyJ
The other person who responded is correct that it's EPS, but significantly, is incorrect about the general superiority of XPS over EPS. I'm not sure about the R-value per inch question (though I think they're very similar), but while XPS may be superior in some other respects, EPS does have the significant advantage of being *more* moisture-resistant over time than XPS and and partly as a result, it maintains its R-value better, again, over time. Bear in mind that short term tests may show the opposite. XPS has greater short-term moisture resistance but, while it absorbs moisture moisture, it also releases it slowly, so it will build up over the long run to a greater extent in XPS insulation than in EPS. Long-term, "real world" testing of in-use material demonstrates the superior R-value retention of EPS when both are exposed to moisture. This may or may not be relevant to a given use, but is worth keeping in mind.

Didn't need to use adhesive most of the time since the friction held them in place. Pro tip: To cut, score with a sharp razor and then snap. If you try to cut all the way through, it will just tare. But you can score it about half way through pretty easily, and then it will snap along that line.
