Stage 1 : Ultra Flex and Security Films ~ this is your first level of protection against break-in's and flying glass. Our top of the line, thin yet extremely strong film, can withstand up to 600 pounds of force slowing or even stopping a burglar or flying object.
Stage 2 : Slow-motion cameras during blast tests determined the weakest part of your windows even with a safety film is attached is around the frame of the glass. A high impact adhesive can be applied around the edge where the glass and film meet the frame.
Stage 3 : 3M's latest technology provides a cleaner, more professional look than the impact adhesives. The new Impact Attachment Systems are a rubber gasket held to the glass and window frame with a hidden, amazingly strong, 3M tape backing.
