Thermal performance
Phenolic Foam panels have the lowest thermal conductivity of any insulation material available. This is mainly a function of the fine closed cell structure of phenolic foam as well as the low thermal conductivity of the gases encapsulated within the cells.
Phenolic Foam Composite Panels have a thermal conductivity rating of 0.02W/m.K. This is a thermal conductivity of around 20% better than the next best product available - extruded polystyrene.
The superior thermal conductivity of phenolic foam panels allows for the use of thinner panels where saving space is a requirement.
The integrity of thermal performance is also guaranteed at installation and is maintained over time as no compression of the panels will take place nor will they settle or depress over time like soft insulation products.
Fire performance
The fire resistance and performance of phenolic foam products is excellent.
Phenolic foam combines low flame spread, low smoke emission and low levels of toxic gas emission in the one product.
In addition there is no dripping of foam during combustion. The honey comb structure of phenolic panels will be retained after combustion to temperatures of up to 300.C and beyond.
In composite form, and where phenolic foam is protected from direct exposure to flame, panels will maintain their integrity for long periods in the presence of fire.
Phenolic foam panels have been certified to meet UK Class 0 fire certification per copy of this report.
Structural strength
Phenolic foams have a high strength to density ratio as well as a good compressive strength. Phenolic foam composite panels have a density of 55kg/m3 and although strong are not structurally supporting.
When used in a structural (supporting) application phenolic foam is typically used in densities of 80kg/m3 and above. Panels of this density will support up to 64 tonnes /m2.
Resistance to chemicals and solvents
Phenolic foam is unaffected by oils, fuels, turpentine, benzene and ethanol. It is also resistant to solvents such as acetone, methyl ethyl ketone and carbon tetra chloride. It is unaffected by products including saturated saline, olive oil and 10% sulphuric acid.
High concentrations of some acids and alkalis will cause swelling and or discoloration.
As a result of its inert and stable nature, and also because it contains no fibers, phenolic foam has been used successfully in the food industry and in areas of exposure to food preparation.
Moisture resistance
Phenolic foam can be used in insulation systems where moisture resistance is a key issue.
The reasons for its excellent performance are:
Phenolic foam has a low water vapour permeance and is therefore highly resistant to the passage of water vapour
Phenolic foam has low water absorption which takes place predominantly in the cut/broken surface cells of the foam
Phenolic foam is non-wicking. This means that if water enters the insulation system due to the vapour barrier becoming punctured, any moisture ingress is limited and confined to the punctured area. This ensures moisture does not build up and compromise the whole system.
Environmental benefits
Phenolic foam has a high insulation value per unit of energy expended in its production. Over the long term this quality compounds the environmental benefit of using phenolic foam
In addition, phenolic foam panels are CFC and HCFC free
