Customer Questions
What is phenolic insulation?
Phenolic foam is comprised of phenolic resin, a blowing agent, and an acid catalyst which is formed under heat and pressure. Kingspan’s K118 insulation board is a high-quality closed cell phenolic foam which provides an ultra low thermal conductivity (lambda value λ) and a very high R-value.
