The thermal resistance of a panel is called R-Value. Polyurethane is an insulating material that is used as core material in a Polyurethane Insulation Panel, with low Conductivity.
As a result R-Value or thermal resistance of panel increases. The lower the thermal conductivity of the panel, the greater will be the R-Value.
How to Calculate R-Value
By using the formula mentioned below thermal resistance of a specific material can be calculated.
R-Value = 1/8(inner skin) + ( ) mm/1000/0.018 +1/20(outer skin)
R-Value = ( ) m2 hr ºC/k cal
Dependce of Panel on R-Value
Polyurethane Insulation Panel is available in the market with different lengths and thicknesses based on the application requirements. The greater the thickness of the panel, the greater will be the (R-Value).
