Determining r value of insulation

WebUsually, the more insulation you install, the more R-value and resistance to heat flow increase. Use the following equation to calculate the R-value for your insulation project : R−Value = ΔT×Area×Time / Heat Loss. ΔT = the temperature difference inside and outside the industrial/commercial space. Area = the area that's being insulated (ft 2) WebAn insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on the …
