Which is better, Phenolic Insulation Board or PIR Insulation?
In the construction and insulation industry, two materials often come under consideration for thermal efficiency, fire resistance, and durability: Phenolic Insulation boards and PIR (Polyisocyanurate) insulation. Both have their unique advantages, but understanding the properties, benefits, and limitations of each is essential for making an informed choice. Here, we’ll break down their differences, common applications, and factors that determine which is the better option for different project needs. 1. Understanding Phenolic Insulation Board and PIR Insulation Phenolic insulation is made from phenolic foam , a thermosetting material known for its high-performance insulation properties and enhanced fire resistance. Its closed-cell structure makes it a top contender for thermal conductivity. In contrast, PIR insulation, a rigid foam made from polyisocyanurate, is renowned for its versatility and durability. PIR has good thermal efficiency and mois...
