Our bespoke insulating glass units can be produced with a wide variety of finishes in an almost limitless variety of shapes. We can provide IGUs with Low-E coatings to reduce heat loss and enable glazed facades to conform and exceed buildin...
Acoustic glass can be used alongside many other products such as thermal insulation, solar control, low maintenance and decorative glass to create multi-functional glazing solution.
Rw is the weighted sound reduction, in decibels, which incorporates a correction for the ear’s response. C and Ctr are the spectrum adjustments, which are the values added to Rw to take account of the characteristics of particular sound spectra.
Typical noise sources for each spectrum adaptation terms are given below:
Relevant spectrum adaptation term C – Living activities (talking, music, radio, TV), Children playing, Railway traffic at medium and high speed, Jet aircraft, short distance away, Motorway traffic >50 mph, Factories emitting mainly medium and high frequency noise.
Relevant spectrum adaptation term Ctr – Urban road traffic, Railway traffic at low speeds, Aircraft, propeller driven, Jet aircraft, long distance away, Loud base heavy music, Factories emitting mainly low and medium frequency noise.
External – Sound control or acoustic glass, minimises sound pollution by combining various thicknesses of glass with a PVB (laminate) interlayer. Effective for use in areas affected by high noise levels, such as road and air traffic, trains, factory, transport deliveries and nightclub noise.
Internal – Use as an alternative for room partitioning to reduce interference from busy office noise, television, music, voices and general workplace/domestic noise.
Recommended for a public and private buildings located a noisy place; use also for room partitioning.
