STC = Sound transmission class that was originally intended for measuring internal sound transmission such as the human voice (high frequency). Rw = Weighted sound reduction index that uses airborne sound and is viewed as being more appropriate for rating the attenuation of external low frequency noise, such as traffic. The window rates STC 34.5 with 8.76 laminated, 9mm air, 4mm float. And 31.5 with 4mm float, 12mm air and 4mm float. These are tested ratings, and we have a demonstration unit (in our standard glazing) in our showroom in Hallam where you can actually hear the difference that double glazing makes. An EcoClassic, EcoPlus PVC Tilt & Turn window 1200h x 850w in 4/12/4 has a list price of $375 + GST with German hardware. With 8.76 laminated, 9mm air and 4mm float the price becomes $515 + GST. BTW. The optimum airgap for energy efficiency is 12mm (ref ASHRAE). Both prices include German timber effect to one side, white is a little cheaper. All of our windows are tested in Australia and guaranteed. Thanks Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

Hi, 3mm float/ 26mm airgap/ 3mm float $711 -----undefined: we have never supplied nor tested float only IGUs in windows 4mm toughened/ 24mm airgap/ 4mm toughened $791------undefined: we have never tested this because we have been advised by acoustic engineers that it is inappropriate glazing combination for noise insulation 8.76mm laminated/ 20mm airgap/ 3mm float $818------STC36 (with second glass 4mm) 10.38mm laminated/ 16mm aigap/ 6.38mm laminated $824-----STC38 10.76mm laminated/ 12mm aigap/ 8.76mm laminated $937-----STC40 actually our casement windows performed better at between +3 to +5 STC difference for like glazing and it works out as a cheaper window style.
