The fire performance of phenolic foam is exceptional. It combines zero or very low flame spread with negligible smoke emission and a very low level of toxic gas emission. Phenolic foam is a thermoset material therefore will not run melt or drip when it comes into contact with a fire source.
Phenolic foam can, in an appropriate form, achieve all the following European fire certifications:
In addition, phenolic foam used in factory engineered composite panels can achieve up to 2 hours of fire resistance (insulation/integrity) in the 3m furnace test.
As part of a ventilated rainscreen façade or a rendered external insulated wall system phenolic foam can limit fire propagation up the outside of the building. Through testing to BS 8414 and BR 135 phenolic insulated systems can meet the UK Building Regulation requirements for use in high rise construction (above 18metres)
Phenolic foam evolves exceptionally low smoke when exposed to fire and is capable of meeting or exceeding all international building regulation requirements.Toxic gas emission from phenolic foam is generally limited to carbon dioxide and carbon monoxide with very low levels of other gases. Phenolic foams can achieve very low toxic gas ratings in tests such as UK Naval Engineering Standard NES 713 and Scandinavian NordTest NT036.
Closed cell phenolic offers the best thermal resistance, i.e. the lowest thermal conductivity, of any readily available building insulation material. This results from its:
Closed cell phenolic foam is also notable in that the thermal properties do not deteriorate noticeably with time
Phenolic foams have an excellent strength/density relationship being lightweight but strong. Higher density phenolic foams are typically used for:
Structural phenolic foam is typically made in 60, 80, 120 and 160 kg/m3 densities.
Phenolic foam has been used successfully in insulation systems where moisture resistance is a key issue.
Phenolic foam has very low environmental impact per unit thermal performance when compared with many other insulation materials
