💡 How does a double bubble radiant barrier improve wall cavity thermal resistance compared to standard batts?
- Selecting reflective foil insulation solves conductive heat flow issues by bouncing infrared radiation back outward before it penetrates wooden framing.
- Crews appreciate how handy this setup stays on wet jobsites since the sealed core halts vapor drift without locking dampness against old wood sheathing.
- Landlords watch electric bills tank quickly because the trapped air pockets deliver steady R value climbing from R8 up to R24 based on facing direction.
