How to maximise noise reduction 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 and acoustic glass, a reduction of 50 decibels (dBs) can be achieved at your property. This will reduce sound by a massive 3dBs – the equivalent of halving the noise 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.
Tip 2: Acoustic Glass
Choosing acoustic glass is also key when it comes to maximising noise reduction. Clearview offer a wide choice of glass options, including a range specifically engineered for acoustic insulation to ensure optimum acoustic performance. Choose from Stadip Silence for a premium solution, or choose a 6mm glass and still achieve significant results.
It’s worth remembering that the inner and outer glass should have different 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.
