541 Polythene Enclosed Glass Fibre Roll
Description

Mayplas 541 Polythene Enclosed Glass Fibre Roll is designed for use in thermal and acoustic applications where loose fibres could cause problems, particularly above suspended ceilings in high tech or sensitive areas. The glass fibre can be glued within the polythene for use in vertical situations.

When used for sound absorption over suspended ceilings, Mayplas 541 will typically achieve a noise reduction coefficient of 0.8 in the range 125–400 Hz.

Benefits:

  • 60–200 mm thicknesses.
  • Vapour check to BS EN 2972.
  • Thermal insulation above ceilings.
