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

Hi Mark,

Assuming you'd prefer to stick with batt insulation, Roxul's Flexibatt
is rated at R22. It's a really nice product that's easy to work with
(it doesn't itch like traditional glass batt).

See: http://www.roxul.com/sw47757.asp

If, however, you're looking for maximum R-value and money is no
object, high density close cell polyurethane foam can't be beat, but
it's not something a D-I-Y'er can tackle on their own.

See: http://www.sprayfoam.org/

Cheers,
Paul
