The company Jahan Ayegh Pars in Isfahan, Iran started with the production of cellular glass due to its unique properties and because it is was hard to get in Iran. I am a little bit surprised about the name because they must be aware about Pittsburgh Corning.

Just like IZOSTEK , STESS and GLAPOR, a family take the initiative to develop a process and build the production facility. Further, they organize succesfully a sales environment. In this case, the company already produces mineral wool, ceramic wool and PIR industrial technical insulation.

In this case, I also measured the gas composition in the cells to check for closed cells and to estimate the thermal conductivity, which is not published. The cells are indeed 100% closed and I estimate the thermal conductivity to be 0.046 W/mK for the 115 kg/m3 density and 600 kPa compressive strength. Although recycled glass is used without remelting, JAP achieved a low H2 content below 3%. In view of the low energy cost, labour cost and recycled glass use, I estimate the production cost of this material between 50 and 70 €/m3. In the Middle East, such a producer can be a game changer. A chromatogram is given hereunder.

We are 100% sure that we hear much more about this porducer in the near future.
