Vinly siding insulation Question


#1

2 questions:

  1. how does the insulation in your attic or between studs on the inside of a house differ from the insulation we put up on the outside of a house as preparation for vinyl siding?
    2)does the outside isulation for the vinyl siding have an “R Value”?
    thank you

#2

The types of insulation that go into attics varies widely…
The insulation you nail to the exterior of a home to smooth out the surface for the new siding is usually rigid polyurethane foam, it is available in various thicknesses and has different R values depending upon thickness and density.


#3

your attic insulation is either fiberglass or blown in cellulose.
siding insulation is a completely different product, that is installed with nails.
