Has anyone used "great stuff" to seal around doors and windows? I live in a "Real Log" home for about six years now and the house has been moving (swelling and shrinking), and doing its thing. Around my windows and doors are voids to allow for movement. The voids are packed with insulation since the home was built and covered by interior trim boards. But I was thinking of removing the insulation and spraying in "great stuff" (for windows and doors of course) for a more sealed off fit. Has anyone else done this? Is six years long enough to wait to spray in a sealer? Would you recommend doing this or should I keep with the insulation?
