RESPONSES TO REQUESTS FOR INFORMATION:

Carolina Premier Window Film

Question #1: We wanted to provide additional information regarding the Clear Armor product specified for this project.

After reviewing the third-party testing provided for the product, we believe there are several important distinctions between the glazing assemblies that were actually tested and the system that may ultimately be installed on the existing windows.

Of particular importance is the UL 752 ballistic testing. The test report identifies the Level 1 specimen as a “1/4 inch Sample,” which could reasonably be interpreted to mean that the testing was performed on a standard 1/4-inch piece of glass with the Clear Armor product applied to it. However, the same report identifies the specimen as “Transparent Armor” and records its actual measured thickness at approximately 0.345 inches. The report also lists the specimen's plies/laminates as “N/A,” so the documentation provided does not clearly identify what materials or construction account for the additional thickness.

This distinction becomes even more apparent when reviewing the higher ballistic levels. The specimen identified as the “1/2 inch Sample” actually measured approximately 0.614 inches thick, the “3/4 inch Sample” measured approximately

0.837 inches thick, and the “1 inch Sample” measured approximately 1.087 inches thick. These reports therefore document the performance of substantially thicker transparent-armor specimens; they do not demonstrate that applying a thin security laminate to a standard existing 1/4-inch pane will produce those same ballistic ratings.

The ASTM F3561 testing provides additional information about the actual glazing construction. That testing was not performed on a single 1/4-inch existing pane with a security laminate applied to it. The tested glazing construction was:

15 mil laminate + 1/4-inch glass + PVB interlayer + 1/4-inch glass + 31 mil laminate.

In other words, this test utilized two separate 1/4-inch pieces of glass bonded together with PVB, with additional laminate layers on both sides. This is materially different from applying security laminate to an existing single pane of 1/4-inch glass.

This distinction is extremely important when evaluating the expected performance of the specified system. If the existing windows are not being replaced or modified to replicate the glazing construction that was actually tested, the provided testing does not establish that the system installed on the existing glass will achieve the same tested performance. The performance of a complete tested glazing assembly cannot automatically be attributed to the laminate alone when the field-installed construction is different from the specimen used during testing.

We also want to bring attention to the distinction between being tested to the UL 752 standard by a third-party laboratory and a product or assembly actually being UL Certified or UL Listed. These are not interchangeable.

The documentation provided demonstrates testing performed by a third-party laboratory using the UL 752 test standard. While that testing may demonstrate how the particular specimens performed during those tests, it does not by itself establish that the product is UL Certified or UL Listed.

Clear Armor represents UL certification in its product information; however, we have been unable to locate Clear Armor or the specified product in UL's online certification database. If UL certification is being relied upon in the specification or in evaluating this product, we believe the applicable UL certification/listing number and the exact system construction covered by that certification should be independently verified.

The testing laboratories themselves also make an important distinction regarding the scope of their reports. Intertek states that its results are applicable to the samples tested and that the report itself does not constitute certification or endorsement of the product.

We are bringing this information forward because, through our experience in the safety and security glazing industry, we have seen significant misunderstanding surrounding what various security products have actually been tested to accomplish. We have seen customers invest in security products under the impression that they will provide a certain level of protection when the specific system being installed has not actually been tested or demonstrated to provide that level of performance.

Our intention is not to discredit a particular manufacturer. Our goal is to help educate customers and ensure that the testing being relied upon accurately represents the system that will actually be installed. With safety and security products, the difference between the performance of a tested complete glazing assembly and the performance of a laminate applied to an existing piece of glass is extremely important.

Ultimately, we want the owner to understand exactly what was tested, how it was constructed, and whether that construction matches what will actually be installed on the project. Customers should be able to make an informed decision and, most importantly, receive the level of protection they believe they are paying for.

Based on the documentation provided, if the existing glass is not being replaced or otherwise constructed to replicate the tested glazing assemblies, the testing does not establish that the finished installation will provide the same performance demonstrated by those test specimens.

We felt it was important to make the project team aware of these distinctions so that the specified performance, testing, certification, and proposed field installation can be evaluated on an equivalent basis.

Response: UL 752 Level 1-(9mm) On August 25, 2026 new test samples for another client, were sent to Element U.S.

Space & Defense-Belcamp. Attached are the results for UL 752 Level 1 (9mm) which should help clarify that our laminate is applied to the back side of the inner 1/4 inch piece of glass. The new test clearly states that Clear Armor laminate is applied to the test sample-1 inch IGU commercial standard glass. Results-No penetration. Although, Ms. McClure requests the construction makeup, Clear Armor's construction process is proprietary.

UL 752 Level 3, 7 and 9-Non-Responsive to this RFP The testing results for UL 752 3, 7 and 9, are non-responsive to this job and should not have been included. Having said that, these tests were completed for another client, but not intended to demonstrate that a thin layer of laminate applied to 1/4 inch standard glass will achieve the respective ballistic ratings. Clear Armor has never made this claim. We educate our clients that achieving UL 752 levels of protection requires considering the glass thickness, glazing system, application, and performance requirements (i.e., requested protection for threat levels). Aside from standard testing, when practical, we submit testing using our clients' glass or the type of glass they use in an effort to custom tailor testing.

ASTM 3561-on Impact Glass The ASTM 3561 results submitted came from an ASTM3561 test performed on a previous client's impact glass, to show our capabilities. This was sent to show our product on impact glass Clear Armor agrees that the distinctions made are extremely important, which is why we try to custom test clients' assemblies and/or glass in order to achieve protection for their respective threat levels.

Certification Upon submission of our marketing packet for publication as a whole, we included our

Certification from the National Institute of Crime Prevention. The information was improperly lumped under one heading and has since been corrected. We thank you for bringing this oversight to our attention.
