    Laser Warning Laser screen media

    Hi,

    I need to project an animation display on a screen whereby I need the screen to be able to withstand some heat generated from sparks that might fall from a nearby fireworks display.

    My concern is if the laser animation will be visible if the media used to project on is a transparent grinding curtain. The screen used will be approximately 5m x 5m and details re the curtain i've identified can be found at: http://www.directindustry.com/prod/c...02-466494.html

    If this isn't the right solution, any ideas/suggestions plse?

    Thanks

    Check out inflatable outdoor screens, I am pretty sure they are tough as. You can hire them here, setup inc. hold downs etc.

    Thks for ur recommendation. Unfortunately inflatable screen is not an option since i require some sort of curtain that can be easily rolled. Thks anyway

    One technique that works very well, is to get a 'boat-sail-maker' or theatrical-co, to sew you a 'scrim', like this:

    http://www.photonlexicon.com/forums/...5&d=1227600849

    ...but you probably shouldn't use that 'Skeeta' material, in this case - sparks, if they hit it just right, would likely melt a hole / do some damage to the skeeta-material,
    so you need to use the 'heavier' fiberglass-based 'Textilene' (...what we used to use, before we found the 'skeeta-stuff', and designed-up a scrim with it...)

    http://www.outdoortextiles.com/brows...atID=7&CatID=1

    The 'advantage' of the Textiline is that it is very-strong / tough, yet will still allow the wind to 'pass thru it', so it is not such a 'sail' and hard to control (though you *do*
    still need very-heavy-duty and properly-set-up rigging by a professional rigger...)
    - also, unlike the 'skeeta', (which you can only use 'pockets' with... grommets 'tear'...) you can use 'grommets' in the Textiline, to make rigging a little easier...

    Here's a pic of our 'old' scrim using it - still good for either front or rear-projection lasers, and yet will most-definitely 'resist' any falling-embers from fwx...

    By any chance, do you have an idea of the ideal mesh that should be used?

    Thks again

    Light gauge woven glassfibre, you could seal the edges with varnish or dope?

    Umm, well, if you're (again) asking about your 'fireworx-fallout-risky' area, I'd suggest you might re-read my post #4, there, again.... but just to be 'nice'... re-post:

    Suggestion, in this-case, is to use the 'heavier' fiberglass-based 'Textilene':http://www.outdoortextiles.com/brows...atID=7&CatID=1

    The 'advantage' of the Textiline is that it is very-strong / tough, yet will still allow the wind to 'pass thru it', so it is not such a 'sail' and hard to control (though you *do*
    still need very-heavy-duty and properly-set-up rigging by a professional rigger...)
    - also, unlike the 'skeeta', (which you can only use 'pockets' with... grommets 'tear'...)
    you can use 'grommets' in the Textiline, to make rigging a little easier...

    But if you were asking about the 'Skeeta', PM-me, and I'll shoot you the details...

    You didn't mention your budget...

    If you're worried about sparks causing a fire, what about a water screen? True, they're pricey, but they won't burn...
