3M Ultra

The Ultra Series Window Films utilise up to 42 micro-layers to provide immense strength and tear resistance compared to standard films. In the case of glass breakage, the fragments are held on the film by the strong acrylic adhesive system. The film delivers superior performance over standard polyester films in blast and impacts, yet still maintains a high level of optical clarity.
