Thread: Window Plug Advice

Hi Folks,

Looking for some advice around soundproofing our bedrooms (Construction noise across the street is p'ing of the missus).

I was thinking of building some removable window plugs for the 2 smaller windows in our bedroom, and a semi permanent plug for the larger window.

I was thinking of an MDF backing with some sort of MDF inner frame that will wedge into the existing frame (so long enough that if the plug tilts, the inner frame catches on the window frame preventing it from falling out), I'd line the inside of it with acoustic padding of some description. Put some basic handles on it so it can be pulled off the windows when we want to open the windows during the day.

So couple of questions:
1. I know that an airtight seal is recommended, but a plug that slots into the frame as snug as i can make it will still have an effect on the noise levels right?
2. Any other idea's for keeping the plugs in the frame and still be able to remove/put back in every day?
3. any other suggestions for materials other than MDF? Gyprock seems to be popular, but i'd imagine that could get messy and i don't fancy fixing one problem for the missus and have it create a whole other problem (namely my 2 year old flaking the plasterboard off in our room).

I realise that noise is probably coming in through the roof as well, i'll be getting up into the crawlspace this weekend to check the quality of insulation, but i'd wager the majority of the noise is coming through the windows so thought i'd try a "cheap" fix to see if that works.

Any input would be appreciated.
