what made you choose this type of scrren
what are the pros and cons
First, welcome to BYT, I'm sure you'll find many answers to your questions.
I chose this particular screen / setup because it affords me the option to change the size as I need it.
I am a sound & lighting rental & sales company and have offered my clients video projection for many years. Recently they have asked for something larger than the normal 106" (8'x4.5") pull down screens so readily available. As you can see I kind of got carried away.
The screen starts out at a respectable 18' wide x 10' tall and will stretch to almost 30' wide x 15' tall. I currently only needed the smaller size which hangs very nicely from a stand rig made up of 30' of triangular trussing suspended from a pair of 17' tall step ladders. This will easily get the screen 15' in the air leaving the bottom approx. 5' from the ground. I simply attach a couple of 5gal buckets to the bottom two corners and fill them with water to keep the screen from moving too much in a breeze.
If at a later date I decide to go insane (although my wife is pretty sure I'm already there) I would need to add additional trussing to make a complete frame to stretch the screen and attach it to. I would also need to find an alternative to the ladders for stands although I can always use additional trussing to make legs and such.
Light weight / compact
screen wads up and stuffs into a small duffel bag
Easy to setup
in the pictures above I've simply attached the screen to the gutter of the barn in the pic. When using the ladders & truss it does become more time consuming but still only takes about 30 minutes to put up.
Can be used for either front or rear projection
Can be thrown in a large washer/dryer or dry cleaned
Ladders are VERY stable with 10' wide base's they aren't going to blow over easily.
Pricey - I paid roughly $550 delivered for mine but it is a custom job with lots of time consuming attachment loops added
Stands/trussing are bulky to store - but then again if you've got a large enough wall to hang the screen from you won't need them.
Stands & trussing are pricey. I'm a Versatruss dealer but still the 10m (~30') cost me $750, the ladders were an additional $620 each and the rigging to safely suspend them will run an additional ~$50 or so.
Hope that helps, feel free to contact me if you need more specifics.
