The projection outline is produced using PVC covered texture
layers joined by high recurrence welding or mechanical sewing. The projection
surface can be made of PVC or spandex, which later accommodating back
projection capacities. The projection surface can be separable for simplicity
of care. The edge is expanded with a high weight air blower. Bigger edges may
require a three stage blower. For greater screens, the blower normally keeps on
working, guaranteeing the screen remains completely swelled. For shopper
advertise and littler screen sizes, the screen is fixed and does not require
always working air blower.
Screens can be held upright with help of a supporting
structure (An outline or inflatable legs), or just with the arrangement of
lashes and stabilizers.
In contrast with customary and overwhelming steel
developments, inflatable screens can be set up just a couple of hours before a
motion picture, with the littlest screens taking only one moment to expand.
This can be valuable for situations where wind or different hazardous climate
might be a factor.[2] Inflatable screens can be emptied rapidly on account of
high breezes, adding altogether to their wellbeing. Inflatable screens are
lightweight and exceedingly compact contrasted with different structures used
to help screens like truss and framework. A 52'/16m wide screen as a rule fits
on a solitary bed. A truss or steel framework takes up a whole truck.
Inflatable screens achieve sizes up to 6,000 square feet (560 m2).[3] The
projection surface remains level paying little heed to condition because of
late enhancements.
