Can you re-phrase the question in simple English so that anyone might understand what your problem might be?

I think it might help to know what the application is: Walls, ceiling, retrofitting, etc... Also, what part of the country are you in (ie: what are the local codes)? Lastly, are you referring to open-cell or closed-cell foam?

OK, first thank you for replying.

and now I'm asking in overall, for walls & roof.

I'm talking about open cell.

Thank you in advance.

I understood the Q!

Sprayed in place foam insulation is far better at providing insulation. it stops both convective, and conduction loss of heat.

Forgetting the convection for amoment, the R value alone is approximately twice tjhat of Blown in cells.

A fully installed foam insulation system will also include doing the ssills to control infiltration which feeds convective heat loss and drafts.

a closed cell foam functions better yet and does a better job aas a vapour barrier too.

The Q about what you meant mauynhave to do with cost vs value simnce foam is more expensive, but any customer I have ever had with the foam raves about all the benefits, one of which is sound proofing. a foam insulated hosue is far quieter than most.

Excellence is its own reward!
