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.

Applications

• Soundproofing against airborne noise in floors, walls and ceilings when used in conjunction with other low surface density materials.
• VL-65 is acoustically equivalent to lead of the same surface weight.
• When bonded between stiff rigid sheet materials it greatly reduces the resonance and coincidence dips.
• Stapled over frameworks it greatly improves the performance of lightweight partitions.
• When bonded to resonating metal panels it greatly reduces vibration and re-radiated noise.
• Offers high acoustic performance when combined with sound absorbent materials.
• Can be used for damping of impact noise caused by atmospheric agents on metal deck roofs.

Acoustic Performance

Technical Data

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 R_w of a stud partition, as shown below, by 6dB.
