Which spray foam manufacturer to choose from
I have two insulation Contractors and each one has their particular spray foam product they work with. One is using Thermoseal 500 open cell with an R Value of 3.7 and Thermoseal 1 closed cell with an R value of 7.2. The other Contractor is using Victory Polymers VPC -50 open cell with an R value of 4.1 and Victory VPC-CC Super yield with an R value of 6.9. The install price seems to be very close. I would like your opinion as to which product would be a better choice? Also is there any concern about spray foaming over electrical house wiring, in terms of the heat that is generated from the spray foam product.
Thank you, Kevin
