Phenolic foam sandwich panels covered by glass fiber cloth on both sides

Short Description:

Phenolic foam sandwich board covered with glass fiber cement cloth on both sidesIt can be manually compounded or automatically compounded by assembly line equipment. It can be used in construction fields such as external wall insulation and roof insulation. It can effectively block heat transfer and has a good thermal insulation effect. It is carbonized at high temperature and does not burn in case of fire. The strength of the composite cement fiber cloth is increased and the adhesion with the base layer is also effectively improved

Product advantages

Product advantages:

 Excellent fire performance

It will not burn in case of fire, carbonize at high temperature, melt, shrink or fall

Very low thermal conductivity

There is no burning sensation on the back of the plate when the flame is sprayed at 150 ℃

High strength

Actual picture of treading on 60kg / M ~ 3 board (the weight of treading personnel is 92kg)

Composite fireproof aluminum foil

Effective improvement of fire resistance and strengr


Material Science weight(Kg/m³) thermal conductivity W/(m·℃) Thermal resistance value (0.025㎡×℃/W) Combustion grade
Phenolic 40~80 0.025 1 Flame retardant B1
polyurethane 20~40 0.025 1 Flame retardant B2
Eps 20~40 0.03 0.86 Flame retardant B2
Xps 20~40 0.041 0.61 Flame retardant B2
Rock wool 80~120 0.053 0.48 Non combustible A
Glass wool 80~120 0.036 0.69 Non combustible A
Foam glass 80~120 0.066 0.066 Non combustible A

Comparison conclusion: phenolic foam insulation sandwich layer has better thermal insulation effect than rock wool, EPS, XPS and other insulation materials, and is equal to polyurethane material; However, the fire resistance of phenolic foam is obviously better than that of polyurethane, and the price is also more favorable than that of polyurethane. Therefore, in terms of comprehensive performance, phenolic foam wins.
