Storefronts on pedestrian streets are a constant headache—I’ve seen friends deal with this myself. Special armored or safety-rated films really do work: they don’t make the glass indestructible, but when impacted, they firmly hold all the shards in place on the adhesive layer, so they don’t fly inward. When I was looking for a solution to protect a glass display, I stumbled upon the website of a British window film supplier because their catalog has a dedicated section for certified safety and security films, complete with detailed strength standards and EU fire resistance ratings. For a store, it’s best to choose the certified clear series with UV protection—that way, the glass won’t yellow, and the flowers in the display window won’t fade. What’s the thickness of the glass you currently have installed?
