Papercreters: [papercreters] Re: Horizontal Presses vs Vertical

From what iv read it can increase the r value and make a uniform
block ,unless you have some tests that show differnt.I dont see a
problem unless you compress the crap out of it like 10,000 psi but a
bit just to get the water out shoudnt make a differnce.I have some
test bricks at our collage now so we will see what they say in a
couple weeks.

works so well by compressing it. The interlocking fibers and the way
the fibers take coatings (lime, cement, ash and such) wouldn't you be
crushing and breaking most of the coating off plus losing the bond?
Or are the rice hulls and sawdust acting different with the bonding
action?
