Constructing a Frame for Interior Window Insert

[timbo12]

Hi,

I am looking to install acrylic inserts using the magnetic seal system and am looking for an opinion on how to best frame the opening. The entire opening is approximately 8' x 8' and is made up of a sliding glass door and a few fixed windows. I have enough room to install an interior frame about 3" from the glass. Obviously an 8' x 8' piece of acrylic is not an option so I need to figure out what to use for a divider (likely 2) and how to secure it.

Additionally, if I figure out what to use for two dividers, what kind of clamps (or other supporting devices) are needed to ensure the acrylic stays in place?

Thanks.
