Question

Which type of foam-in-place insulation would provide you

with the highest R-value rating?
B rigid foam insulation
C open-cell foam-in-place insulation
D closed-cell foam-in-place insulation

Answer 1

Closed-cell foam-in-place insulation provides the highest R-value rating among the options.

Step-by-step explanation:

The type of foam-in-place insulation that would provide you with the highest R-value rating is closed-cell foam-in-place insulation.

The R-value measures the insulation material's resistance to heat flow - the higher the R-value, the better the insulation. Closed-cell foam has a higher R-value compared to open-cell foam and rigid foam insulation because its structure is more compact and less porous, which reduces heat transfer.

For example, closed-cell foam insulation materials like polyurethane typically have an R-value of 6.5 per inch or higher, while open-cell foam has an R-value of 3.6 per inch or lower.
