###### Asked in Statistics, Architecture

### Is r-value good or bad?

it is a good thing i think
R Value is the thermal resistance of a given material. The
higher the R Value the more thermal resistance and the better the
insulation. So, an R48 roof system is warmer than an R32 roof
system.
All insulation materials are rated by their R Value. An inch of
rigid insulation has a higher R Value than an inch of fiberglass
insulation. Check with the insulation manufacturer for the R
Value.

### What is the R value of attic insulation covered with plywood decking?

Every insulation has a different R value. It ultimately is
determined by which insulation you will be using. Now lets do rough
estimate. 4" thick, regular fiberglass mat has R-value of 13.
Assuming that plywood has the same to half the insulating value of
fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that
4" mat. Roughly R-1.6 to R-0.8
