WA Insulation Requirements in 1999?


Recommended Posts

Hi,

You need the WSEC Builder's Field Guide 3rd Edition that was published by WSU. The answer depends on where the home is since there are 8 climate zones with different insulation requirements in this state.

ONE TEAM - ONE FIGHT!!!

Actually, only two climate zones and they both, currently, have exactly the same requirements for underfloor insulation - at least right now - R-30.

I was just surprised to see R-19 under the floor of a 1999 house. I would have expected something more like R-25 to have been required since the early 1990s.
