A: The description is specifically for part RXCB351525. The picture is not showing the correct product. This product is R15
A: R-Value ROCKWOOL product is meant for any stud/joist cavity that would benefit from thermal protection. Your local building codes will dictate what R-Value is required in your walls and you can use a single piece of ROCKWOOL to achieve this R-Value or you can stack the ROCKWOOL pieces on top of one another to add their R-Value together. Eg. Two batts of R15 insulation will provide R30 resistance in your wall. Hopefully this answers your question and we wish you the best on your project.
A: Good Morning Chris. The use of a vapor retarder is dependent on the climate zone and local building codes. Can you email us direct with your location and confirm the application. Thanks firstname.lastname@example.org Note that If the application is for an interior partition wall or between floors, then a vapor retarder should not be a requirement.

A: The R15 bundle holds 12 batts of insulation. Each batt is 47 inches in length which works out to 47 linear feet in coverage
A: This material covers 59.7 square feet. You can calculate linear feet by multiplying by 12 and dividing by width.
