Questions & Answers

what should I buy for a vapor barrier in front of Roxul ComfortBats?

fairfax county code for my basement remodel says: A minimum of R-13 battened insulation (with a vapor barrier on the warm side of the wall) should be installed for the full height and length of the basement wall. what should I buy for a vapor barrier in front of Roxul ComfortBats?
Asked by: Dan
Don't use a vapor barrier for below grade installations. The old notion was to put it on the surface facing a conditioned surface. Yes, that does keep moisture from migrating from the room into the wall. But.... the cement wall is itself absorbing moisture from the surrounding earth and then dispensing moisture. And if there's a vapor barrier in place then the moisture gets trapped. There is significant information on this online published by the US government, Fine Homebuilding, Youtube, etc.. When I was finishing my basement the building inspector insisted on the vapor barrier. I then pointed him to the US government website saying that such a barrier was outdated and indeed causing mold problems in the wall. He thanked me and accepted the rationale. Of course you should use a dehumidifier if you have warm humid summer months. And good air movement (air returns for HVAC systems) is helpful as well.

Is there an easy way to cut the ComfortBatt product lengthwise to trim it down to 1 1/2" thick? I am interested in buying your ComfortBatt product for insulating our walls, however we have only 1 1/2 inches of depth because we are putting the insulation against cinder block walls which have 1 1/2" deep furring strips attached.
Asked by: hellothere
This product is very easy to work with. You can use a 2x4 as a guide and use a serrated knife to cut the length you need. If you are needing to thin a piece out make a cut at the top with grain and pull down slowly like when you pull the non sticky part of a band aid off the sticking part. This is the best way I can describe it. It is way easier that that sounded. Great product to work with.

do you offer a product with R value and sound absortion capability?

I noticed that the Safe and Sound rock wool has no R value listed. But the Comfortbatt is R15. If they are both made of the same materials how can the difference be so dramatic? I am building a one room music studio that is separate from my house. It is a 10x12 room with 8 foot walls. I need to insulate against the weather and against sound transfer. What do you suggest? Thanks you
