The front of the Room (behind the screen) is a double window. I need something that is WAF - meaning that it has to look like "normal" windows from the outside and, if necessary, accessible without having to rip down sheet rock etc. (plus there is a code issue with "perminantely" covering these windows with sheet rock). The entire size of the double window (including top and side moldings) is 63" wide by 66" tall (to this inside of the window sill).
So this is what I came up with:
(4) 1"X4"X8' primed finger joint boards
(1) 4' X 8' X 1/2" sheet Styrofoam insulation
Black Paint and White paint
Here is a picture of the window from the side that gives a good idea of the window sill. There is to be no ripping out of the molding or the sill! so I had to plan around it. The idea was to frame around the window and attach the styrofoam insulation onto the frame with velcro. This would allow for the molding, window sill, and blinds to remain - thus keeping the window in tact and looking like a regular window from the outside - with access if needed from the inside.
Here's side view of molding and sill.
I decided to frame around the window with 1" X 4" finger joint board. The sides and top boards are outside the moldings and the bottom board sits on the inside of the window sill, but the entire frame sticks out further than the sill or moldings.
Next up was creating the styrofoam cover. The 4' X 8' sheet was cut into 3 sections - one large piece and two smaller so as to meet the dimensions of the frame.
The pieces were glued together with crazy glue then "joints" were caulked when the glue set.
When the caulk was dry, one side was painted white (outside facing) and one side (inside facing) was painted black.
Velcro was applied to the edge of the finger joint frame and to the edge of the styrofoam panel.
Then the panel was attached to the frame.
Two more shots from further back.
Some Notes: I wasn't sure how sturdy the styrofoam panel would be, especially the joints where it was glued together. Surprisingly once the glue and caulk set and paint dried, it was very sturdy. This method blocks about 95% of the light as some still seeps through the Velcro. I am not worried however because I will be covering the back wall with Linacoustic (or something similar) which will block all the remaining seepage of light. I will either paint the bottom of the window sill black or the linacoustic will cover.
Next Up: Carpet installers are coming in to measure and provide a bid. I have 3 carpets in mind at this point.
