3M™ Window Film Ultra Prestige PR-S50 and Ultra S400 have a Notice of Acceptance (NOA)*, applicable for use in the Miami-Dade County.

Miami-Dade County, Florida, has some of the most stringent hurricane protection requirements in the world. 3M designed specific safety films that comply with these requirements. These products have received a component approval for small missile impact rating, as shown under Miami-Dade County, Florida NOA No.13-1022.03*, which is effective until August 25, 2016. For glass that is over 30 feet above grade, shutters are not required to comply with building code requirements in Miami-Dade County if you install 3M™ Window Film Ultra Prestige PR-S50 or Ultra 400 with 3M™ Impact Protection Adhesive according to the terms of 3M's NOA 13-1022.03.

Where installed according to NOA 13-1022.03 3M safety films provide constant protection for building windows—so there is reduced need for costly last minute scrambling to install shutters, all the while maintaining the existing appearance of your building.

*This is a component approval and the films described are to be used only on existing NOA approved windows rated for small missile impact with minimum glass thickness 1/4" tempered and tested per the now obsolete roof gravel rocks impact test. To comply with local codes, follow the requirements in the NOA and meet with your local code official.

The 3M Ultra Advantage
  • Ultra technology offers up to 42 micro-layers of strong, tear-resistant safety film
  • Superior performance over standard polyester films in blast and impact events
  • Available in clear safety film or with a tinted sun control option

3M™ Window Films

Security, solar and decorative window films can change your view of what window films can do. Solar and tinted window films save valuable energy and increase worker comfort. Security and safety window films provide shatter-resistant protection in severe weather and bomb blasts. Decorative window films add privacy and style within your building.

Now you can provide sun control, UV protection, window tinting and privacy while increasing energy savings. 3M™ Window Films help improve tenant comfort, reduce hot spots and increase window safety in buildings.

Florida Statute

Under Florida law (Section 553.842):

A product may not be advertised, sold, offered, provided distributed, or marketed as hurricane, windstorm, or impact protection from wind-borne debris from a hurricane or windstorm unless it is approved pursuant to [statewide approval under s. 553.842(5)] or [local product approval under] s. 553.8425. Any person who advertises, sells, offers, provides, distributes, or markets a product as hurricane, windstorm, or impact protection from wind-borne debris without such approval is subject to the Florida Deceptive and Unfair Trade Practices Act under part II of chapter 501 brought by the enforcing authority as defined in s. 501.203.

3M does not have a statewide Florida Product approval, but does have a local product approval in Miami-Dade County in accordance with Florida Statute Section 553.8425. See Miami-Dade County tab for details.

Please contact your local code office to determine applicability of 3M's Miami-Dade component approval in your area.

Miami-Dade County

3M is the first window film manufacturer to obtain a Notice of Acceptance in Miami-Dade County for wind storm protection window products.

3M has obtained a Local Product Approval in Miami-Dade County, Florida NOA No.13-1022.03, which is effective until Aug 25, 2016. This is a component approval and applies to 3M™ Window Films Ultra Prestige PR-S50 and Ultra S400, to be used only on existing NOA approved windows rated for small missile impact with minimum glass thickness 1/4" tempered and tested per the now obsolete roof gravel rocks impact test. To comply with local codes, follow the requirements in the NOA and meet with your local code official.

Windstorm Testing

3M Safety and Security Films have been tested to the industry standards referenced in the Florida Building Code for impact resistance against wind borne debris and protection of glazed openings. Our films have been tested to ASTM E1886 / E1996, ASTM E330, and Miami-Dade County Protocols TAS-201 and TAS-202. These test methods involve impacting the filmed glass with high velocity missiles, ranging from steel ball bearings (simulating roofing gravel) to large 2"x4" pieces of lumber. The evaluation criteria for passing are stringent -- not only must multiple windows be tested, but no tears or openings in the film are allowed after impact. Furthermore, after the windows are impacted with a missile, the filmed broken windows are subjected to hours of intense positive and negative wind loads cycles that simulate the strong gusts of wind experienced during a severe windstorm or hurricane.

Wind Loads

What do the Design Pressures in ASTM E1886/E1996 mean? How do they correlate to wind speed? What is the Design Load of a building?

The Design Pressure is the amount of pressure that windows are exposed to after the missile impacts. The windows are put into a test chamber to model conditions that may be representative of pressures in a windstorm environment. The selected Design Pressures in ASTMs E1886 / E1996 are intended to correlate with the basic wind speeds for a building located in a given region. Each window is subjected to 9,000 air pressure cycles.

People often ask the question, "how does design pressure correlate to wind-speed?"

For example, if testing was conducted at a Design Pressure of 50 psf (pounds per square foot) this would relate to an approximate wind speed of 140 mph. 3M's Impact Protection Adhesive has been tested to a Design Pressure of +/- 70 psf, which correlates to approximately 165 mph wind speed.

The Design Load is the calculated wind load rating for a building, also expressed in psf. The Design Load depends on numerous factors including the average wind speed of the region, the height of the building, terrain, and surrounding structures. If the building's Design Load does not exceed the Design Pressure at which a product was tested under ASTM E1886/E1996, that product may be suitable for use on that building. Typically the architect or building engineer will have documentation of the building's Design Load.

Missile Impact

ASTM E1996 describes several missile types that simulate windborne debris that may impact the glass. The Small Missile test consists of impacting a window with 10 steel balls at roughly 90 mph in 3 separate locations of the window. There are several different types of "Large" Missiles, ranging from Missile Level "B" to Missile Level "E", although missile "D" an 8-foot long 2x4" lumber with an impact velocity of roughly 34 mph, is often referred to as the "Large Missile" test in Florida.
