floating pad. </span><span
style="font-size:13.5pt;font-family:"Gill

under the slab and 30 psi on outer edges. </span><span
style="font-size:13.5pt;font-family:"Gill Sans
MT","sans-serif"">I've been looking at two
products: Unifoam 25/30 and Plastifab 25/30. Aiming for R35
under the slab. Price differential is significant (Unifoam
is nearly $3000 more) for the house. </span><o:p></o:p></p>
<p><span style="font-size:13.5pt;font-family:"Gill Sans
MT","sans-serif"">Has anyone had experience
with either product? From the specs, Unifoam appears to
absorb less water and has less deflection, but both are
within the ASTM spec for the issue. </span><o:p></o:p></p>
<p><span style="font-size:13.5pt;font-family:"Gill Sans

insights!</span><o:p></o:p></p>
