The first time I heard about wet-spray cellulose, I wanted
more information — it sounded too good to be true.
But as I sat in my first informational meeting about wetspray
cellulose, I became a believer.
Advantages of Wet-Spray
Wet-spray cellulose has a slightly higher R-value than
fiberglass — blown onto a 2x6 wall, it gives you about an

more important, wet-spray cellulose fills in around wires,
blocking and everything else, leaving no voids. By doing so,
it effectively eliminates air infiltration and air movement in
the stud cavity in the same way that sprayed-in foam does,
but at a much lower
