Acoustic Insulation for Pipes and Ducts
For indoor or outdoor applications where a "one shot" integral acoustic lagging material is required. Silent Lag SL-B/BM5N/SF and Lagging SL-B/BM7.5N/SF incorporate a 25mm thick glass fibre quilt stitched in a 100mm box design to scrim backing to encapsulate the fibre which isolates the outer barrier from the wall of the duct or pipe, thus maximizing performance.
