Secondary Glazing Specialists3 Noise Reduction Tips You Can Benefit From
by Narzema Arif
Installing secondary glazing is one of the best and most economical ways to soundproof your windows and minimise noise. Although some degree of noise reduction is accomplished by all of our secondary glass, some types of secondary glazing will actually optimise the soundproofing results.
With secondary glazing, noise from vehicles, construction sites, airports, and industrial areas can all be significantly decreased. A 50 dB+ (dBs) reduction in noise can be accomplished at your property with the correct specification; this is approximately 80% of the noise and five times better than double or triple glazing. Three decibels is the same as halving the amount of noise energy that enters a room.
Here are our 3 tips on how you can maximise noise reduction.
Tip 1: Consider the Air Gap
The air gap between the new secondary glazed unit and the existing primary window must be taken into account while installing secondary glazing in order to aid with noise insulation. The better the sound insulation, the wider the gap. When it comes to acoustic insulation, we advise an air gap of 100–150 mm (200 mm if you have the room). The air gap will reduce sound more than the glass and is therefore more significant.
Tip 2: Acoustic Glass
Maximising noise reduction can also be achieved by selecting acoustic glass; however, don’t let the name fool you—while useful, noise reduction isn’t as important as other considerations. To guarantee the best possible acoustic performance, Clearview offers a large selection of glass alternatives, including some that are especially designed for acoustic insulation. For a high-end option, go for 6.8mm Stadip Silence; however, if this is beyond your budget, don’t let it deter you from using a 6mm glass for fantastic results.
To prevent “sympathetic resonance,” which increases noise transmission at higher frequencies, it’s important to keep in mind that the inner and outer glass should have distinct thicknesses and masses. Thickener glass also performs better, especially at lower frequencies. Acoustic laminate glass is especially useful for mitigating noise from trains, cars, and aeroplanes because it contains a unique interlayer that enhances high frequency performance.
Tip 3: Mind the Gap
Noise can enter through even the smallest gap in a window frame, which is equivalent to 1% of the frame size. This can result in a 10 dB reduction in noise insulation. For this reason, Clearview secondary glazing modules are custom-made with incredibly strong seals to minimise leaks and protect the entire window opening.
