Question

What are the factors considered in determining the R-value of a material?

1) Settled thickness
2) Manufacturer name
3) Thermal conductivity
4) Density

Answer 1

The factors considered in determining the R-value of a material are settled thickness, thermal conductivity, and density.

Step-by-step explanation:

The factors considered in determining the R-value of a material are:

1. Settled thickness: The R-value is directly related to the thickness of the material. The larger the thickness, the better the insulation.
2. Thermal conductivity: The R-value is inversely related to the thermal conductivity of the material. Materials with lower thermal conductivity offer better insulation.
3. Density: The R-value is also influenced by the density of the material. Higher density materials tend to have higher thermal conductivities, which can affect the R-value.

Manufacturer name is not a factor in determining the R-value of a material.
