Acoustic Insulation Pads FAQs

How does acoustic insulation work?

Sound travels in waves. To prevent sound from easily passing through surfaces, it needs interrupting, and the best way to do that is with materials that don’t let the sound waves pass through or bounce off them. Some materials are better at that job than others – which is why an empty room echoes (because there’s little to absorb the sound) and a room that’s full of curtains, carpets and other soft furnishings doesn’t.

Acoustic insulation uses acoustic mineral wool to inhibit the transmission or reverberation of sound waves. That means you’ll experience less echo within a room, and less sound will escape it.

How do I install acoustic insulation pads?

Simply place a pad above each tile in your suspended ceiling. It’s quick and easy to do, and as the pads are lightweight they won’t damage the ceiling.

How many insulation pads do I need?

Assuming your tiles are 600mm x 600mm, just count the tiles – you’ll need one for each. Remember that if your ceiling includes ‘double size’ tiles of 1200mm x 600mm, you’ll need two packs per tile.

Do I need to cover the entire ceiling with insulation pads?

Ideally, yes. Look at it this way: a single pad’s acoustic insulation properties are far higher than, for example, the carpet you fit in the room. But a carpet covers the entire room which is why it appears so effective at dampening sound. Unless you do the same with the ceiling, it can’t deliver optimal insulation.  

Will an acoustic insulation pad deliver thermal insulation?

Yes. Almost any material you place on your suspended ceiling will help provide some level of thermal insulation to the area below. And every insulation pad will offer some degree of acoustic dampening. The key question in determining what sort of insulation pads you need is what is the main reason for installing them?

Acoustic mineral wool is specifically designed to address noise transmission. Its thermal capabilities are secondary and, if energy saving is your prime goal, a thermal insulation pad would be the better bet. Conversely, a thermal insulation pad will offer some level of acoustic insulation, but an insulation pad designed specifically for the job will always do it better. So where acoustic performance is your prime concern, choose an acoustic pad.

What thickness acoustic insulation pad would be required to achieve a 30dB rating when placed over a Rockfon Artic 15mm ceiling tile please. I have an area of approximately 400m2 that may be required.

Hi Mike,

all the dB ratings that we have are base on the pads being installed with a mineral fibre tile. In your case, you have a rockwool based ceiling tile which means the ratings would differ.

Due to this i would suggest using either a 50mm acoustic pad, which in conjunction with a mineral tile gives up to 45dB, or increase to a 100mm pad, which with a mineral tile gives up to 70dB.

The 100mm may be overkill but due to the difference in the tiles makeup, this may be an option to consider.

If your require any further help, please do give us a call on 01253 864902 or email us to info@insulationpads.co.uk
