I emailed them last night asking if they can sell the material for me to swap in my current ST and this is what they said.
Currently we do not offer that material with our frames. Management has been preparing to, but at this point does not allow us to sell it for the frames. You can purchase it, without special machines it may be difficult for you to make it.

I have done it and it’s not that hard. You just need to Cut it to size and make the “pockets”.

Yes, I don't have any tool to make the pockets.
looking at the price, it may be worth a try since it's much cheaper to get a 1.3 gain screen instead of throwing away a good frame.
I'm looking to go from 106" to around 118-120" and the increase is not a big jump.

I just used the LePage Heavy Duty Contact Cement. No tools.

What’s the difference between ST White that they sell framed and their Raw material?

Regarding poster above deciding on white screen vs gray, I would say that I definitely would take White screen over conventional Gray. I’ve compared versions of Gray from ST and Seymour before coming to that conclusion.

However, Seymour Matinee Wide ALR material is a completely different animal. I like it. So I’m currently deciding between it, Glacier White and ST White.

The raw material has 1.3 gain (vs 1.1). It has a very smooth texture. I don't understand why they don't use it in any of their screens.

Interesting. I wonder if they don’t want to step on toes of high end manufacturers for whatever reason. Maybe they have an "understanding" between them.
More likely though, it's a business decision for Silver Ticket. They make money by selling high volume while making only tiny profit on each screen. It might be cost prohibitive for them to sell two types of White screens and they want to keep their product line simple and priced similar for the same screen size.

I couldn’t find an official owners thread but this seems to be a suitable spot. My silver ticket screen arrived yesterday. But it will take a few weeks before I can hang it as I’m still preparing the room. Would it be a problem to leave it in the box for a few weeks (would that make it harder to get it mounted without wrinkles later)?

You can leave it in the box as long as you want. Just make sure the screen material is rolled and not folded to avoid creases.

It was warehoused that way for who-knows-how-long so your few weeks will make no difference. Note that depending on your screen material type it is possible (no, likely) that there will be some surface anomalies even after you stretch it out and hang it, but I and others here with that experience did also see them (bubbles, in my case) disappear after some weeks on the wall.

That is because it Hot Spots pretty badly.......so they have an abundance of it available.

Larger sizes (10'+ wide) can come with the material Folded in a separate Box.....unless the Vendor makes arrangements with a Common Carrier Line that will accept out-sized Cartons. Silver Ticket ain't one of them.

ST screens that come from ST...not a 3rd party Amazon Vendor....all come with the material on a roll if the Screen is under 10' wide.

The only concern of leaving it in the Carton for an extended time is that the material can slide down and bunch at one end, depending on how it was stored/transported. Obviously a 10' roll is seldom stored or transported upright....but 8' footers and smaller...it happens quite frequently. Space in a truck can be at a premium, and the Carrier doesn't always consider the consequences if the package isn't marked with a Arrow and a warning.

So it pays to open the Box and give it a eyeball check....then close it up and store the box flat.

Can't speak for them as the reason why, but the 1.3 gain white screen material has no discernible hot spots, unlike their 1.5 gain silver material which has terrible hot spots and blotches. And yet they sell complete screens with the 1.5 gain silver material, but not the 1.3 gain white material.

And I don't follow the logic that "an abundance" will lead to the decision not to use it in a finished screen.

I will post some sample images later today. EDIT: Done. See post 1724 below.

Here are some pictures taken off the screen (Silver Ticket 1.3 gain matte white raw material). Can't say I notice any hot spotting. Even the one taken at an angle shows no visible loss in brightness, unlike screens that hot spot.

The website does not always show the up-to-date inventory. You can contact them by email to see if they have any in stock.

Folks - how does silver ticket compare to spandex? Silver ticket has a 1.1 gain compared to 0.7 for spandex. Is higher or lower better?

I recently had a similar question and got very good replies with calculators that helped me determine which gain was best for my situation. You can find those calculators and formulas here: https://www.avsforum.com/forum/23-sc...oo-bright.html

I have added my question there. Essentially I posted the following.

I am not trying to hijack the thread but am having some difficulty with my situation. So input is appreciated. I have a theater room painted with black ceiling and dark red walls. The room has low ambient light with lights all switched off. I am planning on am AT screen. However since it's a small room, the distance between front of projector screen to front of the lens on an Epson 4010 will be 11.8 feet. For a 119 inch screen size the projector central calculator shows a 63fl (recommended for rooms with high ambient light) at a 2.1x zoom and 1.1 gain (silver ticket screen). If I reduce the gain to 0.7 (spandex), it shows 40fl (again recommended for rooms with a high ambient light). How should I interpret this and what are my options?

This projector calculator seems to be more realistic:
https://webprojectorcalculator.com/

They don’t have the Epson 4010, but using the 4040 the expected luminance is 34 fL. Also keep in mind the ST 1.1 gain screens measures closer to 0.9 gain, so the fL will be even lower.

I am unable to understand the impact of fl vs gain. In the scenario I posted if I go for spandex with a 0.7 gain and 4010 am I ok?

Everything else being equal, fL is directly proportional to gain, i.e., a 1.4 gain screen will give you twice the fL of a 0.7 gain screen.

Is more fl better? In my case in the choice between 63fl and 40fl on silver ticket vs spandex is there a right way to make a decision?

That’s not a simple question to answer.

For non-HDR, 15 fL is considered standard in a dedicated home theatre. It’s good to have some surplus especially if your projector has a manual iris to cut down to output (and the HC4010 seems to have it).

For HDR you need double that, but there are many other factors.

For solid vinyl material I don’t see a strong need for the black backing, unless there’s light coming from the back (like a window). I haven’t found any issues mounting the frame on a solid wall painted in dark colours.

So is this material not suitable for stretching over a frame.

It is. I stretched the material over the frame and mounted the frame on a dark colored wall. There’s no need for a black backing.

With this FL talk I'm curious what mine is. I have the 16x9 120 inch white ST screen using Sony 45es projector. I use eco mode. The projector calculator shows the max FL, but I don't see where you can see diff between eco and high lamp modes?

If anyone likes to take a jab, the lens to screen is 15.5 feet.

Theater room: Sony 45es | 120" screen | Panasonic BDT500 | Rotel RMB-1077 | Outlaw Audio 976 | Klipsch RP-280F/RP-450C/RP-160M | Funk Audio subs | MiniDSP 2x4HD | Crowson Tech MAs | Surgex XR 315 | GIK room treatment

TV Room: Panny 60 inch | Rotel RMB-1075 | Rotel RSP-1068 | Axiom Audio M60/VP150/QS8 |

Try the calculator I linked to in post 1729. It does include your projector (Sony VPL-HW45ES).

What are the hours on the lamp?

https://webprojectorcalculator.com/ has been recommended.
They don't have all the modes, and some of the results are with the calibrated values.

The other way to do it is manually:
1.Take the dimensions of the screen:
http://screen-size.info/
or
https://www.draperinc.com/projection...alculator.aspx
2.Find out the square surface:
https://www.calculatorsoup.com/calcu...calculator.php
3.Find a review with measured lumens and the effect the zoom lens on the brightness:
https://www.projectorcentral.com/son...ge=Performance
4.Calculate how much lens zoom is used:
https://www.projectorcentral.com/Son...ulator-pro.htm
5.Calculate lumens loss due to lamp use.
UHP lamps loose ~25% if their brightness in the first ~500h. After that it's a linear curve to the estimated life of the lamp, which is 50% of it's original brightness.
Different lamp modes affect the lamp's hour timer depending on the brightness. For the HW45, LOW is 40% less bright than HIGH.
If the lamp was used in different modes, take this information from the projector menu and calculate an hour value that includes all modes.
6.Calculate fL for desired mode
7.Adjust for screen gain

2.An 120" 16:9 screen has 42.71 ft²
3.
Zoom Lens Effect. When set to the telephoto end of the 1.6x zoom range, light output is curtailed by only 17% compared with the wide angle setting-a rather modest loss for a 1.6x lens.
4. With an 120" screen positioned at 15"5' (with the HW45) the zoom factor is x1.22 (from x1.59).
x1.22 zoom factor is 62.71% from the total possible zoom.
If from total zoom to no zoom the light loss is 17%, with x1.22 the light loss is 10.6% from whatever mode used (Cinema, Game, etc).
5.?
6. Cinema Film 1 on ECO is 834 lumens. After 500h it's 625.5 lumens.
625.5 divided by 42.71 ft² is 14.64fL
7.?

The result differs from the webprojectorcalculator.


Or get a luxmeter or something similar to measure lumens and divide that by the square surface of the screen.

LE: the environment also matters, the image will be perceived brighter in a treated room (wall reflections, light control), than a room with colored walls and other light sources.
