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:
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
