Maximum Service Temperatures

Quietslab MF mineral fibre slabs can be used up to a maximum temperature of 850UC, but this can vary depending on the compostion of the slab / product. The phenolic resin used to bond the slabs is resistant to temperatures up to 230”C, and above this some resin wil be lost to the hot surface causing discolouration.

Acoustic Performance

Quietslab MF mineral fibre slabs provide excellent sound reduction characteristics by both impending the transmission of sound and by absorption of the sound at the surface.

Noise absorption is expressed as a factor between 0 and 1.0, the more sound that a surface absorbs the higher the coefficient. The composition of the MF mineral bonded fibres makes them ideal for use as sound absorbers due to the high coefficients over a wide range of frequencies.
