wall insulation
Hi...
We're having some remodeling done that involves pulling off some
drywall here and there. The house is not very well insulated, and we
were thinking of re-insulating at least the parts that get exposed.
The contractor told me that r-19 is as high as you should go in walls
and that taking a thicker bat of higher r-value would just get
compressed in the wall and lose its efficacy.
It just sounded odd that we haven't improved the r-value of wall
insulation in 30+ years.
What's the best you can do for wall insulation these days?
Thanks
Mark
