Description

Sonic Liner

10×1.2m 50mm thick

minimum order of 2 Rolls

Lead time 3-10 Working Days.

Sonic Liner is a flexible Glasswool insulation blanket faced with an acoustically permeable black woven glass-cloth on the air stream surface. A 35 mm overlapping flange of the facing material is provided on both sides to enable effective sealing. It provides outstanding acoustical and thermal performance with low air friction.

Key Facts

• Energy saving
• Excellent thermal and acoustic properties
• Maintenance free
• Minimal air friction while optimising free duct area
• Safe application and use
• The air stream will not erode or release fibres into the air stream under normal operating conditions

ACOUSTIC PROPERTIES

Offers exceptional acoustic properties and enhances

indoor environmental quality by absorption of

mechanical noise generated by air conditioning

equipment. Sonic Liner reduces the sound transmission

along a duct.

FIRE PROPERTIES

Non-combustible – tested to SANS 10177 Part 5

Class 1 fire index rating – tested to SANS 10177 Part 3

Tested to ASTM E-84

Flame Spread Index: 20

Smoke Development Index: 10.

APPLICATIONS

Specially designed as an internal acoustical insulation

liner for sheet metal ducts in heating, ventilation and air

conditioning systems operating at temperatures of up

to 120 0C and air velocities up to 20 m/s.
