Substitutes for Fiberglass Insulation
Trying to avoid using fiberglass insulation in walls and ceilings of our 1888 Victorian with balloon framing in Eureka California. Most of the exterior walls are open while waiting to be drywalled. Studs are full dimension. The exterior wall siding is 7/8" redwood shiplap. Is it possible to substitute the new foil insulators like Reflectrix or Prodex which are foam sandwiched between foil?
What about the cotton insulation by Bonded Logic with an R13 value for 3 1/2' walls and R19 for 5 1/2" walls.
Maybe a combination of both. Any other suggestions?
