Phenolic insulation is a rigid type of insulation with a closed-cell structure, commonly used in construction projects such as ductwork, walls, roofing, and flooring. Due to its design and thermal properties, phenolic insulation is the most thermally efficient insulation commonly used. Phenolic insulation is commonly available in R-values between R-6 up to R-24 in a single sheet of board, but two phenolic insulation boards can be used together to achieve higher R-values such as R-30 to R-45 depending on the thicknesses.
Phenolic insulation is made through a process of utilizing a wet foam mix which is first added to the bottom layer of facing. It then expands to meet the top layer. This is then cooked under pressure and cured in a second oven. When ready, the phenolic insulation boards are cut to the right size and packaged up.
Heating, Ventilating and Air Conditioning (HVAC)
The foam is cut to accurate tolerances on computer controlled cutting equipment. Parts available include traditional half sections, slotted slab, foil faced phenolic foam laminate ductboard, radius and bevelled lags, bends, flange box covers, valve box covers, etc. Materials are generally supplied with a vapour barrier facing. High density foam is also available for structural applications such as pipe and duct supports.

Building and Construction
Phenolic foam is used in many building applications, typically continuously laminated phenolic board is used in roofing, cavity board, external wall board, plasterboard dry lining systems, wall insulation, floor insulation and as a sarking board. The superior fire performance of phenolic foam is being recognised and this is leading to increased market share in these areas.
Factory Engineered Composite Panels
Composite panels comprise of a high density structural phenolic foam core with steel facings both sides and an appropriate jointing system. These panels are used in a range of applications including food processing factories, cold stores, semi conductor clean rooms and hospitals. These panels are structurally sound and fit for purpose for use in walk-on ceilings. The excellent fire performance provided by the phenolic foam core gives both good insulation and integrity performance in the 3m furnace fire resistance test.
Process / Petrochemical
Phenolic foam is used in process/petrochemical applications for the insulation of pipework, tanks, vessels etc.
