Does anyone has STC rating for different thickness of clear acrylic
sheets? I believe they are also called Plexiglass?

I am thinking of installing a 4' x 8' sheet on my warehouse ceiling
skylight opening to cut down some noise from the outside, and at the
same time preserve the exterior light coming in through the skylight.

The other option is to use vinyl noise barriers. Has anyone installed
them on exposed ceilings without covering them up with drywall?

Thanks

Here are the STC ratings for Lexan (it is similar to clear acrylic but
has a higer tensile strength). It's sold at the big box stores under the
name Luctite.

Thanks for your fast reply.

Do you know if this product is sold at stores such as Home Depot and
Lowes?

The STC rating is really good. I wonder how much it is for a 4' x 8'
sheet...

It is sold at both of those stores. The Luctite is more expensive then
the acrylic. I recently both a 6 x 4 foot sheet of the Lexan for about
$57. You can get cutters to cut it to the correct size for about $2.00
or you can have the store do it for you.

All the best,
M.

Just don't use a laser to cut lexan... It's heat resistant and with most
tabletop laser cutters there isn't enough power to melt the stuff to cut it.
Plus, it gives of some pretty nasty fumes...

You can cut polycarbonate (generic name for Lexan) with woodworking tools.

Lexan is too expensive for this application. You don't need that
kind of strength, and using the next grade down (Crystalite?)
will save significant money. Lucite is too brittle, though.
