Questions and Answers for Owens Corning R-23 Thermafiber Fire and Sound Guard Plus Mineral Wool Insulation Batt 15 in. x 47 in. (24-Bags)

A:  Hello Lisa, To insulate a crawl space wall you must first lay a strong vapor barrier over the floor that is sealed at any seams and sealed to the walls about 12” up from the floor. The insulation can be attached to the sill plate using long cap head screws or long cap head nails. Vapor retarder for the insulation is not needed in this application. Thank you for your inquiry!

A:  Hello JReed, Owens Corning Fire and Sound Guard Plus is effective for acoustical control. Insulation, by itself does not have an STC rating. The overall acoustical control would be based on all components in the assembly. If you call 1-800-Get-Pink (438-7465) and provide your entire assembly, we can provide a STC rating for your assembly. Thank you for your inquiry!

A:  I use this beneath shiplap on a cabin in Maine. The whole point was to avoid dusty drywall and itchy fiberglas. Works great, and stays in place easily even on ceilings without the need to secure it. What a time and irritation saver. And fireproof too, even for use around stovepipe wall penetration (thimble).

A:  To be quite honest, I don't know how to interpret this data, but this looks like the datasheet you're probably looking for: https://cdn.thermafiber.com/wp-content/uploads/2013/11/NRC%20Data%20Sheet.pdf Less quantitative than the above, but based on personal experience, it's "pretty darn good." I put it in a cabin, and it dramatically decreased the volume of the generator running just outside.

A:  Hello Christian, We do not recommend painting Thermafiber products. Thermafiber knows that when the material is painted, the flame spread characteristics may vary from the published information. The paint is a potential fuel source and may increase the surface burning characteristics of the material. Thank you for your inquiry!

A:  Hello Paul, The need and placement for a vapor retarder is dictated by your local building codes. If a vapor retarder is required a separate vapor retarder would need to be added. Thank you for your inquiry!

A:  Hello dapan, UltraBatt can be used but the cavities must be covered/protected with an air barrier product that will protect the insulation from exterior elements and potential vermin. Need for this can vary depending on the foundation or lack of foundation below the sun room. Thank you for your inquiry!

A:  Hello Nina, Thermafiber UltraBatt can be used around plumbing and pipes. Cut or notch the UltraBatt around the pipe. Slide the batt in behind the pipe ensuring a tight and secure fit. Thank you for your inquiry!
