What is critical radius of insulation?
The critical radius of insulation is a counterintuitive concept within the study of heat transfer.
How much energy does insulation save?
it depends on the r-value of the insulation and the area or temperature range of the climate it is to be installed
Is r-value good or bad?
it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.
An R-value is a rating for materials used as?
