This is phase two of a Safety Shield 800 designer gray 45 with wet glaze attachment system, applying the wet glaze. Dow Corning 995 is being used. This was installed in a home with older floor length windows that were installed before tempered glass was required by code. The primary hazard concern was human safety should a window be broken in a storm or by a person falling into the window.
Having observed a number of wet glaze installations in my community I feel the need to comment on appropriate specifications for this system. In an anti-intrusion, bomb blast or storm mitigation situation, the purpose of the wet glaze attachment system is to keep the filmed glass in the frame despite external force being applied. The most common reason this film and attachment system is installed is preventing or slowing forced entry. In that case repeated blows to the window are being defended against. The strength of the silicone bead is in its triangular shape, and having adhesion to both film and frame. If the top or face of the bead is concave, it will be less able to withstand the force of repeated blows. Additionally, if the silicone bead only adheres to the film and the rubber gasket, the strength of the attachment system will only be as strong as the gasket itself. To conclude, if you are considering having security window film with a wet glaze attachment system installed at your home or business, I recommend asking the installer to specify the size of the bead they will be applying and what criteria they use to determine bead size. If your window or door frame is not conducive to a half inch triangular bead, if the frame is bevelled or has less than a half inch right angle, consider a different attachment system.
