Phenolic Foam Board

Phenolic foam board is a type of insulation material that is widely used in the construction industry. 

It is made from phenolic resin, which is a synthetic polymer derived from phenol and formaldehyde. Phenolic foam boards have excellent thermal insulation properties, high fire resistance, and low smoke emission. 

They are lightweight, easy to install, and provide effective insulation against heat, cold, and sound. Phenolic foam boards are commonly used in applications such as roofs, walls, floors, and HVAC systems to improve energy efficiency and reduce heat loss.
