As per title realy.

I'm building a dedicated cinema room and as it's classed as an internal room I need a fire escape window.

Where do I get a soundproof one (or damn near as) or what do I do to a standard one to make it soundproof?

Hi Ted,

In a Word ... SPACE. Or in two words ....

Air Space.

My House is an extended 1930s build Semi that had all of its '30s glazing replaced with the latest generation of double glazing as part of the Building Job ... actually Building regs insist on the latest kind of Heat Insulating double glazing when you have double glazing installed. BUT, whilst my new glazing does dull the noise from outside it is nowhere near as efficient in coping with sound as the glazing that was installed in a building that I used to work in decades ago and that building had extremely thick walls into which REAL double Glazing was installed . That buildings 'double glazing ' had about a foot of air space between the two not very good old fashioned metal framed and single glazed sheet glass panes ... with the windows closed you just couldn't hear the roar of the heavy traffic in the street outside and this despite the fact that the metal window frames didn't rubber seal in the way that modern double glazing does.

Whilst I'm sure that modern glazing units whose principle purpose is sound insulation can be bought I do suspect that the most effective Sound Insulation is thick walls and as much air space between an outer and an inner window as can be managed.


A quick search and This would seem to indicate that I might be right ...


Noise Reduction and Secondary Glazing


" Secondary Glazing and Reducing Noise from Traffic, Airplanes, Pedestrians, Pubs and Clubs

Secondary Glazing is a special type of glazing construction where an additional pane of glass is added to the inside of an existing single-glazed window. Secondary glazing is often used for SOUND INSULATION – especially if your existing windows don't need replacing or where there are planning restrictions on replacement windows.

Secondary Glazing provides better sound reduction as well as heat insulation than standard single-glazed windows and many would consider it essential for houses close to busy roads or other high noise generating objects. "


That old building of Days of Yore was Much, MUCH better sound insulated than the Ghastly Glass and Concrete, Modular Constructed, and Ever So Modern Building in which I worked just before retirement.


I hope that this helps,


Arnold.

Cheers for all that!

sounds like there is no such thing as a soundproof window then, simply adding to a new modern one is the way to go.

Laminated glass is what is used. Two sheets of glass with dis-similar thickness. Laminated together with a poly film that damps a bit. Like the windshield of your car.
