I ordered 4 yards, and asked specifically for it to come in a roll. This was done via a Phoned In order
Anything sent other than a uncut length of requested would be a error expected to be corrected.
I believe the width is 54".
A 150" diagonal is 73" x 130"
The 4-Way Spandex from Spandex World is 80% Spandex, so it will easily stretch out the needed 18" (13" for screen 5" for Spline-ing or Stapling)
The TS/OP needs 4 yards for each layer.
In the Photo below, a 2.35:1 screen of 135" is shown with Silver Milliskin draped inside
(135" @ 2.35:1 = 52" x 125")
..................and now the White Milliskin stretched over the Top:
Here are images with a White Milliskin remnant laying across the finished, White Milliskin surface. You will note the difference in shading.
(Silver Milliskin second layer "grays" the white)
notwithstanding, the dual spandex produces a spectacular image.
(PJ is a Panny 8000 at minimum Throw)*
The whole premise behind this "speculative" issue is that there would be actual pixel transfer from the rear back into/onto the front surface...which would have to depend on the production of the individual Pixel grids on the second surface....something this is not going to happen after the absorbed light is scattered.
The use of Black behind Mfg AT screens is for one purpose alone. helping the appearance / perception of contrast. And for it to wok, it must be directly against the AT material, and be totally non-absorbent. That is to say light that hits it scatters, not pass through.
Silver, by determinations I have made, serves to deepen the color of the returning light, but with no shifting. Intensity is lessened, but the the net effect is no different than using a Light Gray screen instead of a white one.....with the resulting benefits...and caveats depending if one fails to accommodate it's strengths.
I'm not sure where the idea....or demand that Spandex perform as well as a solid surface in either minutely observed clarity or reflective luminosity.. I mean really....such a issue has always existed with woven, Mfg Screens and just slightly less in Perforated Screens, owing to their available reflective area between the perforations..... which of course heralds Morie all to often. Talk about REAL pixelation issues!
Gee...ya know of course that Spandex is HIGHLY Morie resistant.
I don't think much of the supposed "failings" of Spandex will hold up very well against the reported successes that many will present.
Over and over and over and over and over again...of course.
Nothing wrong with these White over Silver Spandex screenies.
Lastly Craig5571, if you construct a frame where you wrap the the Silver Milliskin Spandex , spin it around and hang it so it lays directly and firmly against the White wall, you can go with just a single layer.
I'd try that first...because it might be a step saver, and if not, well the next step is to overlay the Silver with the White in any case.
