Phenolic insulation panel is made by a process which the insulating core is formed by a plastic foam between two flexible tissue faced layers. There are high closed cell content and fine cell structure.
The rigid phenolic insulation is produced by using high solid and phenolic resin which mixed with a surface acting agent. The reaction creates heat which evaporates liquid blowing agent within the mixture and make small bubbles inside the material. The foam boards has a very good ability to insulate and keep heat inside. This made it become the most used material for insulation of buildings in cold areas, large consumption for constructions everyday.
