Read about Expanded Polystyrene For ICF's
Polystyrene For ICF's
is the measurement of thermal insulation.
ICF foam is rated on its
thermal properties, density, strength, and resistance
to wind and moisture. Foam density can have significant
impact on the physical characteristics of the
foam, especially thermal insulation (R-value),
strength, and moisture retention.
Remember when working
with expanded polystyrene (EPS) foam has an R-value
that ranges from 4.0 to 4.2 per inch when dry.
Expanded polystyrene is the most common foam for
ICF's. Expanded polystyrene is resistant to air
infiltration and can be molded to create flat,
grid, and post-and-beam cavities in block, panel
and plank systems.
ICF's made of extruded
polystyrene (XPS) foam have an R-value of 5 per
inch when dry regardless of density. Like expanded
polystyrene, extruded polystyrene (XPS) is resistant
to air infiltration, but stronger. It's ordinarily
available in sheet form only and is more expensive
than expanded polystyrene.
The below ground conditions
in freezing or wet climates can degrade the foams
R-value. For this reason extruded polystyrene and
especially expanded polystyrene, should have moisture
protection when used below grade to protect its
R-value. According to the Building Foundation Design
Handbook, expanded polystyrene in ground contact
is best suited for application in well-drained situations.
The correct waterproofing and drainage is a must.
