Tackling The Great Debate - Open Cell Versus Closed Cell Insulation
In part 2 of our case study on open cell and closed cell foam we get into the nitty gritty of what makes closed cell foam different from open cell and truly unique.
If you want the best floors in the winter time you have to go with 2 inches of closed cell foam.
It has a great “perm” rating or “permeability” rating. It will not absorb moisture.
Here’s what you must remember: When an R value is given to a product it is done under factory conditions. It assumes there is no moisture present. If you use open cell foam under your house or in an exterior application, you are instantly changing and decreasing the insulating value of your product.
