Motorized Screen : Tab Tensioned vs weighted bar

I think I have narrowed down my screen size now to a 120" 2.35:1 motorized screen. Question, I see Tab-Tensioned options which I know keeps the screen nice and taught. But it's obviously cheaper to get a screen with just the weighted bar at the bottom and no tensioning.

Is a Tab-Tensionsed screen really worth the extra $$$? I have never owned a screen before.

If you don't want wrinkles/waves then yes it is worth the money for tab tensioned screens. All non-tensioned screens eventually develop wrinkles/waves, some materials it is not as noticeable but none are invisible.

My dad and uncle invented the first tab tensioned retractable screens back in the late 70's. Both of them were avid sailboat racers and got the idea from their collective experience of properly setting sails so they would not have any wrinkles. (No wrinkles in the sails meant a faster sailboat) That said, the bottom bar is actually called the screen batten but I also hear, "bottom bar" all the time. Non tensioned screen materials are somewhat simi-rigid with a impregnated fiberglass backing that does not allow any for any dimensional adjustment in the X-Y axis and can set with wrinkles in the viewing area. Because of the fiberglass reinforcement, this type of material is very robust, difficult to tear, inexpensive to produce and was/is the first choice for abusive environments such as K1 through 12 schools. For that, it does its job well. On the other hand, a tab tension screen material has a non reinforcement backing so it allows some stretch and elasticity to the screen material. With a properly weighed screen batten and the correct catenary curve geometry cut to the outside screen edges, a tab tensioned screen can dimensionally adjust from the provided tension and be as flat as a fixed frame screen.

Between Elunevision and Grandview for a 2.35:1 which would you get?
Please be advised that it would not be appropriate or ethical for me comment on other screen companies. I am sure others here can help you with that.

Great story Don, thanks for sharing it.
Isn't it great how things get invented trying to solve other applications?

Thanks for your contribution to our hobby.

Stewart's Cima line are a great choice - tensioned, great material, and not as expensive as the regular line. I love my Cima Neve !
