Product description
VL-65 is a high mass, visco-elastic acoustic damping membrane with the added advantage of improved low frequency performance over our other acoustic membranes. It is internally reinforced with a micro fibreglass carrier for improved dimensional stability.

VL-65 eliminates the coincidence dip around 2.5kHz found in rigid sheet materials such as plasterboard on studwork by 12dB.
The tests below show standard studwall constructions with and without VL-65 sandwiched between the sheets.
The low frequency resonance dip at around 160Hz is reduced by 8dB.
This superb material will improve the overall averaged Rw of a stud partition, as shown below, by 6dB.
