RoscoView: Variable Intensity and Exposure on Windows; this product sold in lots of five (5) units.
RoscoView is a unique two-part window control system for film and television professionals. It consists of wide width polarizing filter installed on windows and a matching camera polarizing filter. The window filter is available in easy-to-handle acrylic panels or in the traditional soft roll form. The camera filter is optical glass. Rotating the camera filter changes the degree of cross polarization on the window where the RoscoView filter is installed. This results in 100% control of exterior brightness as seen through the window. To the naked eye, the ambient light coming into the room or studio is reduced by only one stop.
Always have a small sample of RoscoView to examine panels as you are installing them. Be sure that the orientation of the panels remains the same when placing multiple panels. Otherwise, checker boarding will occur.
When mounting RoscoView Panels on a window, leave a minimum of 1/2 inch spacing between the glass and the RoscoView panel. This limits thermal transfer and allows the panel room to deflect. Leaving a space at the top of the panel will allow air movement, again limiting thermal transfer.
Small spacers could be placed at the bottom of a panel to permit any condensation to collect evaporate before being wicked up into the panel.
Do not use alcohol based cleaners to clean the RoscoView side.
To clean, dust off the panels before cleaning with liquids. A "Swifter" has worked well in the past. This removes larger debris before wiping, thus reducing the chance of scratching. Be sure to clean both sides of a panel before mounting in place.
A good glass cleaner should work well for wiping the panels. Watch for residue left from the liquid used, change cleaners if there is streaking. Use a lint free cloth or micro fiber cloth and avoid rubbing hard.
When cleaning, moving and placing panels, wear cotton gloves to prevent transfer of fingerprints or dirt from your hands.
To hold panels in place, use an aluminum L bracket secured to the mullion with TESA #4965 double sided tape. Ensure that the mullion material is clean and will hold the tape.
Consider how large an area will need to be supported and adjust your bracketing solution accordingly. Multiple panels and a very large area may need heavier brackets and permanent fastening (screws).
Panels cannot be effectively "butted together" without some evident light leak through the seam. We advise against "butting" to cover large areas or join using an "H" channel of aluminum or acrylic available from Rosco.
