Fragment Retention
Armorcoat 4-mil Stainless Steel 20 Clear's 4 mil construction helps retain broken glass fragments after impact.
Armorcoat 4-mil Stainless Steel 20 Clear pairs Solar Gard Armorcoat's 4 mil safety construction with a warm stainless metallic tone with 46% VLT, softer than a hard silver mirror. The single-pane data lists 46% VLT, up to 45% heat rejection, and over 99% UV blocking, so this SKU is best understood as glass-retention film with a specific appearance rather than a generic tint. It gives entry-level Armorcoat safety construction an architectural finish that coordinates with brushed metal, bronze, or warmer glass palettes.
It works for lobby sidelites, restaurant entries, boutique offices, and mixed-use storefronts where owners want privacy cues without a cold reflective facade. The local Philadelphia use case is practical: exposed glass can break during impact, vandalism, attempted entry, or severe weather, and owners often need a retrofit that improves retention without replacing the whole glazing system.
Technically, the 4 mil layer helps retain fragments after impact while the stainless finish contributes moderate solar control and a more designed appearance. Armorcoat safety film helps retain glass fragments and delays forced entry when it is matched to the glass type, frame condition, and any required wet-glaze or attachment system. It should never be presented as absolute protection. For most projects, the film thickness decision should follow the risk level, opening size, and whether the location is interior or street-facing.
Choose it over Silver 20 when the building needs warmth rather than a cooler mirror; choose 8 mil Stainless Steel 20 when the project calls for a heavier safety layer. The result is a more specific specification: Armorcoat 4-mil Stainless Steel 20 Clear is selected for its thickness, finish, daylight level, and risk profile together.
Armorcoat 4-mil Stainless Steel 20 Clear's 4 mil construction helps retain broken glass fragments after impact.
With the right glass, frame, and attachment details, the film delays forced entry at vulnerable openings.
Its stainless tone softens the safety retrofit so metal hardware, mullions, and warm interiors feel coordinated.
