Different linear relationship between R-value and insulation thickness

[rmax]

Can WUFI account for the different linear relationship between R-value and insulation thickness?

For example, polyiso insulation has an R-value of 6 at 1 inch thick and R-value of 13.1 at 2 inches of thickness.

Is it possible to input R-value as a function of thickness in WUFI?

This way, when the material thickness changes, WUFI would automatically use the corresponding R-value from the input data in the model.

Dear Diego,

WUFI can not account for a non-linear relationship of the R-value.
In the as calculation that is not needed, as the thickness can not be change during the calculation itself.
Only way at the moment is to insert such materials as separate materials depending on the thickness.
See Pavatex-Isolair for example:

But we will discuss that for future development.
