LLumar N1040 SR PS4 - Safety/Security

About N1040 SR PS4 - Safety/Security

N1040 SR PS4 is a lighter neutral solar safety film that keeps glass more transparent while adding entry-level fragment retention. With 40% visible light transmission and 4 mil construction, it is a measured choice for occupied rooms where comfort and safety both matter. That makes the specification both a comfort decision and a glass-retention decision, which is why the tint level and mil thickness need to be considered together.

Philadelphia schools, offices, rowhome entries, and community spaces can use this product when clear safety film feels too visually unchanged but dark 20% solar safety film would over-tint the room. It helps manage glare while maintaining a welcoming appearance. On Philadelphia projects, N1040 SR PS4 should be evaluated by elevation, room use, and how much glass faces sidewalks, transit, neighboring rowhomes, or open sky.

The 4 mil layer helps retain glass fragments after breakage and can delay forced entry in a properly specified system. The 40% VLT gives modest solar control and UV reduction without the stronger daytime privacy associated with darker films. In practice, 40% VLT and 4 mil tells the project team how assertive the neutral result will feel once installed, not just how it looks on a sample card.

Choose N1040 SR PS4 when basic retention and moderate tint are enough. Step up to PS8 for higher retention demands, or shift to SCL clear safety film where maintaining the original glass appearance is the main priority. Window Film Philadelphia can compare it against adjacent LLumar options from Eastman Performance Films so the final selection matches the building, not just the product category. Samples should be judged in the actual room whenever daylight, privacy, historic appearance, visibility, or color is close.
