Plyguard Phon is a special brand for sound insulation fire-retardant plywood. The structure of the fireproof material includes cork, rubber or composite cork-rubber sound absorbing barrier. This complex solution meets the requirements for fire safety, sound reduction and damping of vibration. All layers of birch veneer used for production of the panels are impregnated with flame retardant. The weight and soundproof properties of the fire rated plywood Plyguard Phon depend on the type of barrier: sound insulation panels with cork are lighter in comparison with standard birch plywood and thanks to its fireproof properties they are widely applied in shipbuilding. Sound reduction plywood with rubber core has high antivibration properties and is mostly used for metro trains and rail vehicles production, but it is also applicable in other areas. It helps to decrease the negative impact of vibration on human safety and health.
Fire-retardant panels Plyguard Phon are compliant to Requirement R10 of EN 45545-2 for rail vehicles production.
Sound absorbing fire rated plywood is a multi-purpose material. On customer’s request it the can be overlaid with protective coating based on resin or HPL.
