Sound Reduction and U-Values

Sound Reduction and U-Values

Sound reduction with double glazed units is an increasing concern for clients and specifiers to improve habitations where noise is a problem, generally in heavily populated areas.

Slimlite Double Glazed Unit cavities are filled with a mixture of Krypton inert gas which is much heavier than the standard Argon and therefore provide much better sound reduction than standard units. The widths of cavities has little or no effect on sound reduction. Therefore each cavity will have the same effect.

Sound reduction in standard double glazed units 2 panes of 4mm glass with Air Cavity - 25 Decibels.

slimlite Double Glazed Units - Sound Reduction (Acoustic Insulation)

Constructed:

Example: Normal noise reduction RW = 31 Decibels - Traffic Ctr = 27 Decibels

4mm Low E/4mm Cavity, gas/4mm clear 31 Decibels,  Traffic 27 Decibels, U-Value 1.9 
4mm Low E/5mm Cavity, gas/4mm clear 31 Decibels, Traffic 27 Decibels, U-Value 1.7
4mm Low E/6mm Cavity, gas/4mm clear 31 Decibels, Traffic 27 Decibels, U-Value 1.4
4mm Low E/8mm Cavity, gas/4mm clear 31 Decibels, Traffic 27 Decibels, U-Value 1.3

 

Other Constructions - Sound Reduction

Constructed:

 

6mm Low E/4mm Cavity, gas/4mm clear 31 Decibels,  Traffic 30 Decibels, U-Value 1.9 
4mm Low E/4mm Cavity, gas/6.8 Optiphon 35 Decibels, Traffic 31 Decibels, U-Value 1.9
4mm Low E/4mm Cavity, gas/10.8 Optiphon 38 Decibels, Traffic 34 Decibels, U-Value 1.9

Sound is measured over a range of frequencies and sound reduction is shown in Decibels, and a 3 Decibel reduction in sound will be very noticeable.

The higher decibel figure reflects increased sound reduction.

NOTE: The laminated accoustic product reduces ultra violet radiation by 99%
