Difference Between PIR and Phenolic Board
In the construction and insulation industries, selecting the right material is critical to achieving both energy efficiency and fire safety. Polyisocyanurate (PIR) and phenolic boards are two popular options, each with unique properties that make them suitable for different applications. Here, we explore their differences in terms of composition, thermal insulation properties, fire resistance, moisture performance, and cost. Understanding the Basics: PIR vs. Phenolic Insulation Board PIR (Polyisocyanurate) Board is a type of thermoset plastic that has gained widespread use as insulation. Known for its high thermal performance and strength, PIR is typically chosen for roofing, walls, and floors in both residential and commercial buildings. Its lightweight nature makes it easy to install, and it offers substantial resistance to heat flow, making it a good choice for energy-efficient buildings. Phenolic Insulation Board, on the other hand, is made from a phenolic resin that is ...
