There are different kinds of noises, and knowing what type of noise you want to block is the first step to seeking a noise reduction solution.
Base noise travels on a low frequency Hertz (Hz) while treble noise travels on a high frequency Hertz (Hz). For this reason, it is important to note that the weighted average ‘Rw’ figures alone can be misleading if you do not identify the exact noise offender/s and look at the matching decibel (dB) blocking factor for that frequency range.
Low frequency noise can travel through solid objects more easily than high frequency noise. This is why we normally hear the base sounds vibrate through solid objects. When it comes to glass in windows and doors, mass (thicker glass make-ups) is best for blocking low frequency noise while acoustic laminate is ideal for blocking high frequency noise. Combine the two when wanting to block a full range of different noise offenders.
Australian Glass Group offers both product and technical support in this area. Audioshield is a high performance acoustic laminate that uses a special interlayer for superior sound reduction. Audioshield is available in a range of thicknesses also to allow a full range of noise blocking – single glazed in 6.5mm, 8.5mm, 10.5mm and 12.5mm as well as the ability to add into an Insulglass Insulated Glass Unit (IGU).
AGG recommends single glazed Audioshield as an ideal internal wall/glass door option to maximise your acoustic performance between internal rooms. For external windows and glass doors, we offer the best of both worlds when partnered with a high performing LowE coated Double Glazed Unit (DGU). Here you have hundreds of different make-up options to choose from to suit your needs and compliance with all non-acoustic factors also.
In addition to superior acoustic performance, Audioshield also delivers:
- Grade A Safety certified to AS/NZS 2208
- Strength against breakage and penetration
- Over 99% UV protection to reduce colour fading factors
