Cost/Pricing issues
« on: February 18, 2019, 03:17:59 PM »

Just moved into a new construction house but proximity to highway and traintracks is making me see a sound reduction solution. I've read the various posts on the forums, google and have looked around at pricing. I have a number of windows that are basically 70x60, for this size of window I'm getting pricing ranging from $800~$1150 from suppliers like ezsoundproof, indowindow, soundproofwindows etc.

On the other hand, my local plastic supplier is quoting me $330 for a sheet of 3/8 acrylic of that size, on top of which I can add a Magnetseal component, which is looking like the total for a DIY to be around $500 or $550 maybe, not sure about shipping costs.

I guess at the end of the day my question is, is it worth saving a bit per window for a custom acrylic solution vs a prebuilt solution with glass? I was hoping the custom route would be much cheaper than that. What have you all been choosing?

Got it, thanks Randy that was indeed one of the threads I looked at as well. It mentioned using two 6mm / 1/2" acrylic sheets, something about weight being a factor. The price quote I sought from my local supplier was directly just one 3/8" sheet. Should I be looking into 2?

6mm is 1/4" which he corrected on a later post. but 3/8" 10mm is diminishing point of return.

In the end it will always be mass / gap / mass.

you have quoted the correct size.

Ok, so 1 layer of plexiglass of 3/8" should work? How should I measure the width and height needed, i.e. an inch more than the actual window opening or more? Same question on the height, I know the plexiglass sits on the windowsill but how much overlap on top?

P.S. The verification questions are...not that intuitive. There's got to be a better system :)

1 layer of 3/8" will work fine. hopefully you have 2" or greater sill depth.
Depending on your install, if you are going to rest the acrylic on the window sill then it would be 1" at the to and 2" additional inches for the width. you are basically using the L frame as corner framing, except at the bottom.

P.S. I am not in charge of the verification questions sorry.

Got it ok no problem. Can a regular window sill support the weight? I'm told the 3/8 71x60 acrylic will be 67 lbs..

Another question on measuring: One of my windows has no sill, so I need to do a recessed mount. How much clearance compared to the actual window opening should I try to get a window for? An inch less width-wise and height-wise? Or even less than that?
