What is the R-value of phenolic foam?

What is the R value of phenolic foam? Keli’er, a phenolic insulation board manufacturer from China, will answer your question
The R value of phenolic foam has great advantages over the foam materials currently sold on the market. The R value of 10 cm phenolic board at 10 ℃ is 5. If you want to increase the R value of the material, you need to increase the thickness of the board. Because the R value of the poor insulation is determined by the thermal conductivity and thickness of the material itself. The thermal conductivity of the material is certain and will not change much, so if you have selected a material, When the thermal conductivity is constant, the R value can only be adjusted by adjusting the thickness.
The thickness of phenolic foam insulation board produced by Clear Company can be customized as required, and the thickness of 20mm~230mm can be produced to meet different needs.
