Wall Aluminum Foil High Density Phenolic Insulation Board

  • W.T

Why Choose Phenolic Insulation Board?

The process of making phenolic insulation board involves using a plastic foam to create a layer of insulation between two flexible facing layers.

Just like PIR boards, phenolic insulation boards have a high amount of closed cells and a fine cell structure. To produce rigid phenolic insulation, a mixture of high solids and phenolic resin is combined with a substance that helps with surface action. The heat generated by this reaction forms numerous small bubbles within the material.

The foam is then cured and formed into thin sheets through a continuous process. These sheets are then laminated with different facings and cut into boards.

The wall high density phenolic insulation board is a top-notch thermal insulation material widely used in the construction industry. It is crafted from a rigid foam core made of phenolic, with a waterproof facing on both sides. This feature makes it perfect for external wall insulation systems. The high-density board boasts exceptional thermal insulation properties, with low thermal conductivity and fire resistance. Moreover, it offers excellent compressive strength and dimensional stability, ensuring long-lasting durability and performance. By installing wall high density phenolic insulation boards, you can achieve significant energy savings on heating and cooling expenses, while enhancing indoor comfort. They are user-friendly, lightweight, and resistant to water absorption and mold growth, making them an excellent choice for sustainable building projects.
