Design
The screen is made from PVC coated fabric layers joined by high frequency welding or mechanical sewing. The frame is inflated with a high pressure blower. Larger frames may require a three phase blower. The blower typically continues to operate, ensuring the screen remains fully inflated.
In comparison to traditional and heavy steel constructions, inflatable screens can be set up only a few hours before a movie. This can be useful for environments where wind or other dangerous weather may be a factor. Inflatable screens can be deflated quickly in the case of high winds, adding significantly to their safety. Inflatable screens can be highly portable compared to other structures used to support screens like truss and scaffold. A 52'/16m wide screen usually fits on a single pallet. A truss or steel system takes up an entire truck. Inflatable screens reach sizes up to 6,000 square feet (560 m2). The projection surface stays flat regardless of environment due to recent improvements.

Famous quotes containing the word design:
“Nowadays the host does not admit you to his hearth, but has got the mason to build one for yourself somewhere in his alley, and hospitality is the art of keeping you at the greatest distance. There is as much secrecy about the cooking as if he had a design to poison you.”
—Henry David Thoreau (1817–1862)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
—Marilyn French (20th century)
