Economical, Long-Lasting, Flexible Sealant
CZ-4. Net Zero Energy Home. New Construction Ranch . Concrete Slab-On-Grade. Planning for 0.1ACH50. Using Huber Zip-R panels with (1″PolyIso laminated to the OSB).
I want to use an economical flexible sealant between the Sill Plate and the Concrete Slab that will last as long as the house; and I want to use a sealant with similar characteristics between the foam of the Zip-R panels and the framing to ensure an air tight seal. I plan to use it liberally to help get to that 0.1ACH50 and it would be particularly nice if it were also economical. I’d appreciate advice on which sealants would meet these criteria.
I’ve read about the use of many sealants including acoustical sealants, Prosoco Joint and Seam Filler, etc. etc. and many others that I’m sure that are flexible and long lasting but I fear are not also economical. A product called Geocel has been locally recommended but I don’t know about it’s suitability.
Would folks with experience with sealants make some recommendations ?
