Looking for more information regarding applying sprayfoam insulation on lumber treated with BoraCare. Difference between open and closed cell?
Yes, it is fine to use any kind of insulation once the Boracare application is dry, typically in about 24-48 hours. Boracare will not interfere with an insulation application unless you do not allow the Boracare to be completely dry.
