Figure about $3.00 sq ft for the reflective sheeting about $120.00 for a 10 ft diagonal screen. The frame was made with three 2x4's ripped into 2x2's. A simple squared rectangular box as the wrap around stretch frame and two inserts diagonally to support the frame. This would equal a rectanguar shape with 4 2x2's vertically thru the width of the screen and a 2x2 capping the top and bottom.
Then lay the frame down and decide which is the top side. On the top side staple on a skirt. The skirt is any material that is thin and can be bonded to with packing tape or any other think high stick wide tape. Make this skirt about 4" tall and as long as it takes to reach from the left to right edge of the frame with the material pulled snug. I used a 2 or 3 mil painters poly coth Ihad but you can use any material just be sure it is strong and thin. SNug it across the top of the frame on the screen side. It will be covered over on the front by your screen clot but standing on the back open side you will see this skirt exposed with 2" showing just below the frame. the other 2" is stapled to the frame and the purpose of this is for the first layer of reflective material to anchor to this rigid starting point and not rely on the screen cloth to suspend it's weight. Otherwise you'll get a wrinkle as the cloth gives way a bit to the weight of the reflective sheeting. This plastic skirt serves as a transparent anchor point to hold the weight of the material while the remainder bonds to the screen cloth but does not rely on it for support.
Bill ,thanks for the samples you sent me. We talked a while back about this screen here and because of LIFE (HAD 2 MAJOR EXPENSE CAUSE ME TO PUT MY THEATER BUILD ON HOLD)
ANYWAYS: I want to make sure i do this sample the correct way. looking at the screen as your watching a movie.........
it should be screen material cloth (main side projector light/image hits)
2.Then behind that your highway sign reflective sheeting?
This is where I am confused......
(is it the sticky BACK side of that sheeting stuck to the first main projector screen?)
So in other words ...if there was no main projector screen there ..you the viewer would see the projected image on the sticky back side.
Or is the design/color part of the reflective material is face-up behind the main screen and the sticky part is stuck to the skirt?
So if you remove the main projector screen you the viewer would see the image on the same side (front) of the reflective material ?
Sorry if i seem slow on this part , and I lost the email i had when you may have answered this when you sent the samples......just want to double check and make sure...
thanks again for the sample.
I think i may try a dark grey mate spandex
as the screen itself and your material behind it in my build. reason because with a screen hold from lowes i can get a nice tight even pull on a frame.
I am leaning towards Viewsonic pro8200. its a bright projector and since this will replace my t.v with a 3 yr warranty and long lamp this may work,(n.d. filter if its to bright also)
I have about as much light as you have in your post. so need something for day time. was looking at Mits hc4800 also but don't think it will work in day light but the picture seems great from reviews at night.
