Projection screens can be finished in several different ways depending on how you plan on using and hanging it. At Gerriets, we break that down into five different "Models" each with a different type of finish, all are high frequency welded with almost invisible seams. When ordering screens, remember to take into account the height and width of all edge finishing as well as the viewing area. To request a quote, click here and enter in your information as well as the overall, relaxed dimensions of the screen, the type of finish you want and projection surface of your choice. Feel free to contact us as well if you have any questions about ordering your Gerriets screen.
Model 0 / Raw Edge Screen
Model 0 screens are just panels of raw projection screen material welded vertically together with no edge finishing at all. These are typically called "raw edge screens" because of that. Raw edge screens are typically cheaper than screens with edge finishing but it is up to the customer to find a method of securing and tensioning the screen. This model is typically used when tensioning and stapling a projection screen permanently to a frame.
Model 1
Model 1 also has vertically welded seams but also has reinforced webbing, grommets, and tie line at the top, small hems on the sides and a pipe pocket on the bottom. These screens are a standard model for most stages since it is manufactured similarly to most large stage drapes. The screen is tied on the top to a pipe batten or truss and is then tensioned by the weight of the screen and the weighted pipe on the bottom. Since the screen is only attached at the top, it is easily flown in and out via a fly system or chain motor.
Model 2
Model 2 is very similar to Model 1, but instead of hems on both sides, it has webbing, grommets and ties, which allow for the screen to be tensioned from side to side as well as from top to bottom. This is typically used when the screen is hung within a truss arch, where the top and sides are tied to the truss and bottom hangs freely.
Model 3
Model 3 has webbing, grommets and ties all the way around the screen. Allows for even tensioning all the way around the screen. It is typically used within a truss frame, where the screen is either bungeed to the truss frame (such as with our SPANNFIX bungees) or tied on via the lace and grommet method. Because the bungees are used, the screen can expand and contract with the weather, making this a good option for the long-term installation of screens.
Model 4
Model 4 has the reinforced PVC webbing all the way around the screen with snaps every 8” (20 cm). This model is used so any of our screen surfaces can be mounted on our VARIO or MONOBLOX frame systems. The screens are fitted to the frames in our workshops, ensuring each snap lines up correctly. This is why we recommend purchasing the screen with the frame, otherwise, we require the frame to be sent back to the workshop for a new screen to be fitted.
Skirt
A skirt can be welded on the bottom of either Model 1 or Model 2 screens, in front of the pipe pocket. The skirt is usually made 2” longer than the pipe pocket and this height is included in the total screen height. Skirts are used to both create a light blocking seal on the bottom of the screen and to hide the “smile” effect that is common when a weighted pipe is used on a very wide projection screen. They also can be used in front of a strip of webbing, grommets, and ties that are for tying a weighted pipe to the bottom of a screen. This method is sometimes used for very wide screens where there would be too much resistance to push a pipe through a pipe pocket.
Hook and Loop Fasteners (not shown)
Hook and loop tape may be welded or sewn onto either a Model 0 screen or a screen with hems all the way around. These are typically used to attach the screen to a metal frame or a set piece. We recommend having the loop (of soft side) tape attached to the screen, with the hook (or hard side) tape attached to the frame. We also do not recommend running an entire length of tape along one side, but instead put loop tape on 6” (15 cm) tabs along the side to allow the screen to stretch. A full piece of hook tape can be used on the frame.
Seam Direction
Our normal seam direction is vertical, we believe these seams tend to "disappear" more than horizontal ones. If horizontal seams are absolutely necessary, the customer assumes all risk. We do not guarantee horizontal seams as there is adverse stress due to excess weight from the overall size of the screen.
