Questions & Answers

Im putting this in a crawl space. Beams are 2x6. Do i need some kind of vapor barrier or some kind of air ventilation.

Asked by: HomeProject
No, do not install vapor barrier in crawlspace. You should have adequate ventilation through the foundation vents.

I have a crawl space in my townhouse between the 1st and 2nd floor. Will this product stop heat transfer between floors?

Asked by: Vizzle
Heat rises do if you're trying to keep the upstairs cool I think you would just make it worse (take longer to cool down). If you're trying to keep the upstairs warm and downstairs cool then yes. If you vent the crawlspace to keep the upstairs cool that's your best option based on the limited information in your question.

can i use this between metal studs?

Asked by: NickyWu
Shouldn’t. It won’t fill the u shaped void in the metal stud, thus leaving large gaps. There is a Rockwool product made specifically for metal framing that is a full “16 or 24” wide so there are no voids. I don’t see this product on HDs website. Maybe you can go to the pro desk and ask. Definitely get the specific “model” number from rockwool’s website and take that with you.
