ISOLFON- PB is a lead noise barrier. It is made by combining two layers of impermeable reticulated polyethylene foam that are separated by a 0.35 – 0.50mm thick lead sheet to achieve noise reduction in low and high frequencies.
Fields of application
Insulation of rooms, engine compartments, piping, floors, partition walls, machinery, conduits in general.
Soundproofing membrane with lead sheet ISOLFON PB is recommended in particular when water or oil particles are present in the vicinity of the panel. Suitable for use as under flooring in civil constructions when it is desired to prevent sound entering or leaving a given environment. The antivibration layers consist of highly flexible foam with high resistance to compression.
This material has excellent sound insulating properties. Many construction materials and techniques do not provide enough sound damping. Rigid sheet materials such as plasterboard absorb little sound energy because they tend to vibrate and re-radiate sound on the other side quite effectively but ISOLFON– PB is the optimum solution in projects that require easy of use, quick installation and best possible acoustic results.
- They can be applied on any surface – either flat or curved.
- No requirement for special tools for handling and installation.
- They can be cut in size and shape with a conventional knife.
- They can be applied with glue or mechanical fixing.
The noise reduction offered with the sound-proofing material ISOLfon– PB is illustrated below:
|Length:||6m (custom length upon request)|
|Reaction to fire:||Class 2 (self-extinguishing)|
|Apparent dynamic stiffness:||s’=67 (MN/m3|
|Weighted Sound Reduction Index R’w:||R’w=27 dB,
according to ISO 140:3 & ISO 717:1
Helps to increase the transmission loss of walls and ceilings, and especially in light/dry construction
Polyurethane foam panels that trap sound and reduce reverberation time.They offer increase sound absorption, reduce unwanted sound reflections, elimination of flutter echo, reduce room modes/standing waves, in music studios and acoustic sensitive spaces.
