foil backed osb

tractorsteve | Posted in Energy Efficiency and Durability on

I can buy foil backed osb cheaper right now than regular osb.  Pro’s and con’s? It would be used on a hip roof over indoor pool . Asphalt shingles will be very dark.  Paint store has a paint called E Barrier to paint under side of exiting osb for same purpose.  Pro’s and con’s on it.

    It will be a vapor BARRIER due to the foil facer -- no drying at all through it to the side with the foil. Aside from that, I don't really see any downsides. Just make sure to plan your assembly properly with regards to drying.
