Is there any reason why I should not use magnetic tape on both the acrylic AND the window frame, instead of the metal frame? The weight of the acrylic will rest on the window sill, so the magnets can just create the seal. I would use temp DAP removable caulk on the bottom between the sill and the acrylic.

Also, are there any recommended suppliers of cut-to-size acrylic on the internet? I can't seem to find any reliable suppliers near me.

The magnetic tape is not designed to magnetize to itself, it needs to have steel for it to work properly.

go onto google and type in " plastic suppliers (your postal zipcode)" and it should come up with local companies that supply plexiglass.

Thanks, Randy. Another question: If I don't plan on removing the plexiglass, could I use something like DAP removable caulk instead of the magnet & frame?

Also, the material I am looking for is Plexiglass / Acryllic, right? There seem to be a lot of variations.

yes you can do that type of installation, our magnaseal system is for the ability to remove it.

and yes it is plexi glass/ acrylic 1/4" min. 3/8" max..
just think about it like the window of a commercial airliner..same thing...2 pieces of 3/8" safety glass with a 2" dead airspace.

I agree with Randy, however it really depends on the degree of isolation you require.

I have a handy calculator on my publications page; Reflections Boundaries Mass excel spreadsheet. Download it to determine the thickness of material to suit your STL requirements. Laminated or Tempered Glass FAR outperforms Acrylic, most due to the greater mass. When sound-proofing mass and seal is what 'does the trick'. Mass also determines the lowest frequency that will be attenuated.

How much isolation do you require?
What is the frequency range of your isolation requirement?
