Flexible, Long Lasting, Sealant
In upper CZ-4, I will be placing Huber Zip R-6 panels ( with 1″ of PolyIso on the interior) against 2×6 stud walls and plates. I would like to use a sealant between the PolyIso and the bottom & top plates and around the windows and doors. A Huber rep recommended the use of a Silicone Sealant or a urethane based sealant. An article that I read recently, “Making sense of caulks and sealants” indicates that silicone does not adhere well to wood.
Would you please recommend a sealant that adheres well, remains flexible forever, forms an airtight seal and of course is economical.
