    摘要: This invention describes a method and apparatus for window foiling in a burglar alarm system. Precut geometric shaped metallic foil patterns are removably mounted on a support means. The patterns are mounted in its full shape. The window is initially foiled with straight line segments using conventional foil. The precut foil patterns are removed from the support and connected to the straight line segments in an overlapping relationship therewith. The overlapping portions can be perforated to provide good electrical contact therebetween.
