How to maximise noise reduction with secondary glazing

How to maximise sound proofing with secondary glazing

One of the most effective and cost efficient ways to reduce noise and sound proof your windows is to fit secondary glazing. And, whilst all our secondary glazing will reduce noise to some extent, there are certain types of secondary glazing that really will maximise the sound proofing results achieved.

Noise from traffic, road works, an airport or industrial estates can all be substantially reduced with secondary glazing. With the right specification, a reduction of 50 decibels +(dBs) can be achieved at your property, this is approx 80% of the noise and 5 times better than double or triple glazing.  3dBs – is the equivalent of halving the noise energy entering a room.

Discover the best ways to maximise noise reduction with our top 3 tips.

 

Tip 1: Consider the Air Gap

If you are installing secondary glazing to help with noise insulation then consideration of the air-gap between the existing primary window and the new secondary glazed unit is key. The wider the gap, the better the sound insulation. Where possible, we recommend an air gap of between 100mm-150mm for acoustic insulation (200mm if you have the space). The air gap is more important than the glass and will do the lion share of the sound reduction.

Tip 2: Acoustic Glass

Choosing acoustic glass is also helpful when it comes to maximising noise reduction, but don’t be overly swayed by the name, it’s good but not a significant factor compared to other specifications. Clearview offer a wide choice of glass options, including a range specifically engineered for acoustic insulation to ensure optimum acoustic performance. Choose 6.8mm Stadip Silence for a premium solution, but if this is out of your price range don’t be put off, you can still get amazing results with a 6mm glass.

It’s worth remembering that the inner and outer glass should have different thicknesses/mass to avoid ‘sympathetic resonance’ which increases noise transmission at higher frequencies, and that thicker glass improves performance, particularly at lower frequencies. Acoustic laminate glass has a special interlayer that helps improve high frequency performance and is particularly suited to dealing with traffic, rail and aircraft noise.

Tip 3: Mind the Gap

Even a tiny gap in a window frame – 1% of the frame area – can allow the passage of sound that can reduce noise insulation levels by as much as 10 dB. That’s why Clearview secondary glazing units are tailor-made with very effective seals to shield the whole window opening and minimise leakage.
