Acoustic HeatShields



Description
M949 Acoustic HeatShields are manufactured from long strand glass fibre needlemat, faced one side with reinforced aluminium foil with self-adhesive backing on the reverse.
M1019 Acoustic HeatShields incoporate an additional polymeric barrier core to further improve sound transmission performance.
They are designed to provide both thermal and acoustic insulation in areas exposed to extreme variations of temperature and high levels of noise emission from metal surfaces. Acoustic HeatShields are available in sheets or can be die-cut to size and shape.

Colour Outer face Silver
Inner face White

Application
Acoustic HeatShields are used extensively in hot, noisy environments such as power generation plants, industrial burners, compressors, marine rooms, military vehicles, earth moving equipment, aircraft, commercial transport and railway rolling stock..

Operating Temperature
The adhesive face of Acoustic HeatShields can be used at continuous temperatures up to 180¡æ. The reflective face can withshand radiant heat up to 250¡æ.

Thermal Conducitivity - 0.035 W/Mk @ 10¡æ

Fire Performance
Acoustic HeatShields comply with the Class ¡®O¡¯ requirements of the Building Regulations, when tested to BS476: Part6: 1981 and Part 7: 1987.
They also meet the requirements of FMVSS 302/ISO3795.

Storage and Handling
M1019 Acoustic HeatShields should be stored in dry conditions and in an ambient temperature between 18¡æ and 25¡æ. This is to ensure the polymeric barrier core remains flexible for ease of application.
