I'm having a local company do my corner install, however i just realized the hearth pad I bought with the install is only r-1.18. How do I make up the .32? (manual requires r-1.5).
I though of buying metal 2x4's and laying them flat in the same outline as the pad, figuring 1" dead air is r=.97. or should the outline be done with 1" over hang of the pad? I've never worked with the metal 2x4's how do you attach them keeping the side against the floor and the top flat i.e. no screw heads?
The pad is going over laminate wood flooring which is over concrete.
Would it be easier to build the pedestal with the 2x4's not laying down especially if I'll tile it. I'm freaking out because i only have two days to get this done.
