Comparison of thermal insulation
Thermal features of standard building materials (based on Israeli standard number 1045)
* The calculated conductivity is the value used for the calculation of the thermal insulation features according to the establishment of standards and takes into account the water content in the material during its practical use. |

It needs to be mentioned that the tested thermal conductivity values of the foam produced by Polyurethane Ltd. are even lower than the value used for the standard calculation, as can be seen below in the test results carried out by the laboratories of Bayer AG, the world leader in the PU market. Following are the test results (PU sample marked with LEU-2147-SH9-5):

Below are pictures taken with an infra-red camera. In effect, this photography is carried out according to heat of objects in the area (similar to military and civil systems for night vision). Hot objects are those that emit a lot of heat to the environment and appear in the “warm” colors (on the upper edge of the scale to the right of each picture): red, orange and yellow.
PU insulation foams of the IN series are produced by Polyurethane Ltd., owner of knowledge agreements with the German concern Bayer AG, for manufacturing and selling PU systems. The foams have been successfully applied for some decades around the world for different applications: spraying of residential housing, casting/pouring of elements for the insulation of cold store, spraying of agricultural constructions, casting of refrigerators, picnic boxes and many more.
