Thermal Performance - ASTM C158 (
R-Value)
R
3.6 per Inch Avg.
2"x4" = R 13 Avg. 2"x6" = R 20
Because Icynene is a spray in place foam it is always custom fit,
so it will maintain a consistent, absolute R-Value for the life
of the product.
Air Permeance - ASTME 283
0.0049 l/s-m2 @ 75 Pa
for 5.25" 0.0080 l/s-m2 @
75 Pa for 3.25"
This means you require No Additional Interior/Exterior infiltration
protection.
Vapor Permeance - ASTM
E96
16 Perms 941
n/g @ 3" 10 Perms 565
n/g @ 5"Icynene is Hydrophobic
meaning it will not absorb water, however water will drain by
gravity.
Upon drying, will return to its full thermal
capabilities.
Flame Spread - ASTM E84
Flame Spread <20
Smoke Development- ASTM E84
Flame Spread <400
Fuel Contribution- ASTM E84
Zero
