Environmentally friendly as it releases no ozone depletion chemicals or gases during the manufacturing or recycling process as PU can recycle with the whole panel for reuse.

During the recycling of panels, no environmentally damaging chemicals are produced with great reliability.


7. What is the Core Difference Between a Polyurethane Insulation Panel and a PIR Insulation Panel?

Polyurethane Insulation Panel

It is a highly stabilized and heat resistant unit, used for construction for over years. The core of the panel consists of PUR that is designed by the use of two components as



Both of the components are used in a balanced ratio during PUR production. High thermal resistance and low conductivity are its main features.

PIR Insulation Panels

PIR panels are also heat-resistant units used for a variety of applications requiring heating insulation or inside cooling. The core part of the PIR panel is made of PIR that is also designed with the same components as PUR.



But above both components are not used in balance ratio for PIR manufacturing but instead amount of these chemicals is used according to molecular masses.

Ring-type structure and linking of PIR, make the panel more stabilized. Thermal resistance is the key feature of a PIR panel.


8. What is R-Value and How Polyurethane Insulation Panel Depends on R-Value?


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).

If the thickness of the panel ranges from 2 to 20inches or 50mm to 200mm then the thermal resistance of the panel will also increase respectively as from 2.95 to 11.28 m2 hrºC/k cal.

R-Value of a panel helps to select a panel for a building or specific application according to its environmental factors.


9. How is a Polyurethane Insulation Panel Insulated?
