The resultant R value of 2" of 2 lb foam is R12. The resultant R value of the installation done here is R22. The cost is higher than installing 2" of 2 lb, however it is significantly lower than the cost to install R22 in 2 lb foam. Different applications require different approaches and this is a cost effective, high R value solution some homeowners find very attractive.
The use of Roxol allows us to achieve the best of both worlds - the client is provided with the benifits of foam (High R value, low air and vapor permeance qualities) at a lower cost than a straight 3 inches of foam. Because foam is a far more expensive product than fiberous materials, we get the benifits of using foam without incurring the cost of a pure foam application.

so you're saying that they difference b/w 2" and 3" of foam is more than the material cost of roxul, and the labor to install? seems off to me....

why bother with the roxul? if you're spraying 2" for a VB it'd be cheaper to just spray 3" of foam.....?
