I am writing to let you know that the 3M sun protecting film installed on our windows is a much better product than I ever expected it to be. On April 19, 1995 at 9:02 a.m., 4,800 pounds of explosives were detonated in Oklahoma City. our building is approximately six blocks away from the Alfred P. Murrah Federal Building. The windows in our building are seven feet wide and 12 feet tall. When the bomb went off, one untinted window over the entry door was shattered by the pressure and blown into the reception room. One tinted window in my office withstood the initial pressure but was blown out by the resulting vacuum. I feel certain that had I not had the 3M film on the windows we would have lost more windows to the blast and that the window in my office would have been blown into the building instead of being sucked out onto the patio. I was in my office directly across the room from the only tinted window we lost and I feel that the only reason I was not severely injured by the blast was the protection provided by the 3M film.

The window has been replaced and new film reapplied. If there was ever proof that your product is truly exceptional, this is it. It also performs flawlessly at keeping our offices cool by reflecting the heat of the sun. Our air conditioning bills are significantly reduced as a result of having applied the 3M film.

You may use this letter as a testimonial to the high quality of your product. Thanks.

Sincerely,

John T. Spradling, Jr.
