H.S. Engineers sound barriers are high density limp-mass material made of high-temperature fused vinyl and no lead fillers, Very usefull to control airborne sound transmission through walls , floor and ceiling Mass loaded vinyl sound barrier available in various thickness – 3mm , 5 mm , 8mm thickness , the density will be 1700 Kg/m3 which play very good role to control noise transfer.  The STC can be achieved up to 60STC by using mass loaded vinyl and Rockwool / Concrete wall Combination.

Technical data

Test	Value
Density (g/cm3)	1.90 ± 0.05/td>
Pliability (UEAtc)	Does not break when bent at -20 ºC
Tensile strength (UNE 104-281/6.6)	30 N/cm2
Elongation (UNE 104-281/6.6)	300%
Crushing strength	4.84 Kg/cm2

Properties:

• High acoustic insulation, combined with flexion-pliable elements (sheet plaster, carrier board).
• Flexible.
• High elongation capacity.
• Easy to handle and adaptable to uneven surfaces.
• Hot and cold-resistant.
• Self-extinguishing.
• Excellent ageing-resistance.
• Rot-proof.

Applications:
• Airborne noise insulation in vertical surfaces with low surface mass (lightweight partitions or panels in various materials).
• Airborne noise insulation in ceilings.
• Reduction of impact noise level in all types of frameworks, in formation of floating floors.
• Damping of impact noise produced by atmospheric agents in metal roofs.
• In combination with sound-absorbent materials, it results in products with high acoustic performance characteristics.
• Its applications in the industrial sector range from soundproofing booths to insulation of machine rooms, drainpipes, acoustic damping of
metal sheeting, etc.

 

Usage:

Sound Barrier or Mass Loaded Vinyl are applicable in all new construction buildings, intended for any of the following uses:
– private residences
– public residences (hotels and residential homes)
– administrative and office space
– healthcare
– teaching use
