I'll be doing some testing and providing some very detailed results for each material, including what doubling up the material does. Keep an eye out for a dedicated thread.

PS. when the spandex world stuff got here I was blown away how thick it is compared to my fabricland and joanne's stuff eek.gif


Thanks for doing the work Tux. Looking forward to your thread.

Yeah, I used 3yards each of the spandex world silver and white matte moleskin materials. That stuff is pretty thick, and heavy.

Awesome! This is exactly what I've been waiting for. Thanks Tuxedo

Awesome. Will you be comparing them visually as well? I'd be curious how Joanne's or other local spandex compares to the SpandexWorld that is the staple here.
post #215 of 544
Yes I will be, although I only have grey spandex world and white Joanne's. the focus will be more on sound. I have taken some screenies though. Just need some time to measure.
post #216 of 544
anyone know what's the gain of the spandex world silver and white matte moleskin? what about white over silver & silver over white?

I don't think anyone measured it.

But based on what I've seen with white/silver, I am guessing it's probably around .8 since it look as dark as the unique gray paint, which I believe was around .8 gain.
post #218 of 544
I wonder how white/white compares to Joanne's.

Tux, will you use a light meter with CalMan or HFCR?
post #219 of 544
Nope. Don't have that capability. Just acoustic measurements and screen shots. BTW I've started my thread on the subject. And I found my screen shots so ill hopefully post them today.

Apologies if I've missed this but a couple of questions about the diy frame:
  1. Is the screen attached to the front or the back of the frame via the Screen Tight base strips?
  2. Are the Screen Tight base strips the 1 1/2 in size?

My pics are on the first page.

Also, most people prefer to build an outer frame in front of the main frame to wrapped the fabric around so that it doesn't directly hit the main frame and the middle support bars.

See post #58 for some pics, and let us know if you have other questions. I built my outer frame using 1x2 (which is actually 3/4 by 1 1/2).
post #224 of 544
Great! Thanks for the answers. Now I'm off to post #58. I'm sure I'll be back with more questions as I intend to use this type of frame. Thanks again.
post #225 of 544
Has anyone used this for other AT material like smx or seymour? Not sure if the Screen Tight channel would be the right size.
post #226 of 544
Great information that everyone has been posting. I'm almost done with my first screen built (130"). I'm going to use the spandexworld milliskin white and light silver. I'm not sure which will be the projection layer yet, but I'm leaning towards the white.

Quick question about the screen tight. What did you guys use to cut it with? Design1stcode2nd has really tight corners on his and I'd like to get the same result if possible.

thanks,
Erik

@ design1stcode2nd - Do you have a build thread or more pictures?

Are there any pictures of the spandex/screen fabric material being installed?

I just used my miter box, cut very slowly so it didn't chip, its just plastic.

Fabric hasn't been installed yet, I need to finish my screen wall and will probably finish most of the room before I wrap the screen. that way I don't need to try and store a 10' screen in a construction area. I'd be paranoid I'd get a mark on the spandex. I will have my cleats and make sure it's ready to go I just won't put the fabric on until the end of the build.

That's good to hear (read). When I was looking at the pictures, I thought it was aluminum.

Do most people use the caps (from Screen Tight) or do the splines keep the fabric secured enough?

I'm a little concerned with installing the spline with the pizza cutter wheel tool. In the past I have ripped my share of screen replacing it on screen doors but my tool was metal and it looks like the Screen Tight tool is plastic.

Spline is more than enough to keep the fabric inside.

Yes, the pizza wheel is plastic.
post #231 of 544
Thanks, again.

Hmmm pizza!

A bit off topic but that Screen Tight stuff looks like a perfect alternative to the Fabricmate channel for installing fabric on walls/ceilings. Has anybody done that or seen anyone do it?
post #233 of 544
Cool. Thanks for the advice design1stcode2nd. I got my spline and screen standoff installed and it looks great. Now I just need to smooth transitions with wood filler and smooth some surfaces and I'm ready to stretch fabric.Here are a couple of shots of the completed frame:







post #234 of 544
^Very nice, efaust!
  1. What size screen will it be?
  2. What did you use for the screen standoff (lumber size)?
post #235 of 544
Thanks angryht. The viewing size is 130 diagonal. I can't remember what the exact size of the stand off pieces was. I'll go check but I think it was somethin pretty standard.
post #236 of 544
Looks good and you are welcome. If you get to streching the spandex before I do pass on any tips.
post #237 of 544
1. Can someone tell me the actual dimensions of the spandex (Spandexworld) as far as length. Example 3 Yards ? X 108" or would it be 108" X 108".

2. I am new to this DIY Theater and trying to figure out how much spandex do i need to order for 2 layers. White/Silver, 110" Screen

3. Would the spandex have better black levels or contrast than the standard blackout fabric sold on Amazon?

I built a 110" screen with 3 yards of spandex, and had plenty of leftover.

White over silver provides a pretty dark image, comparable to a gray paint (roughly something in the region of .8 gain if i have to guess).
post #239 of 544
Ask for the Spandex to come on a Roll, not folded and boxed. Virtually no wrinkles that way.

Think of the spandex width as the height of the screen. Most come in 58 or 60 inch widths and if the spandex is four-way stretch you can stretch the height by about a third. Three yards will make life easy and provide some excess. White over silver will end up being a light gray that will improve contrast over a regular white screen such as blackout cloth. Blackout cloth has a gain of < 1 as does the spandex but the boc can be painted to give >1 gain and improved contrast with the appropriate paint formula.
