Boxing: U.S. Bullet Proofing windows are carefully packed in plywood boxes. Each unit is cushioned throughout with styrene packing to prevent movement inside the box. Each box is marked with the identification of the unit and the shipping address. The weight and cubic feet are indicated. Each box is further marked with “Up” arrows, indicating how the box it to be transported and stored.

Shipping: Each box should be visually inspected from the outside for any damages that may have occurred during shipping. A damaged box will often result in a damaged window, especially in overseas shipping. In the event of damages, if possible photograph the box and notify the factory or the freight company. This must be done within 30 days after receipt of the unit.

Storage: It is not desirable to store units for long periods of time. However, this is often unavoidable due to construction schedules. If the units must be stored, they should be placed in a dry warehouse with moderate temperatures. High temperatures and humidity can cause formation of vapor inside the polyethylene wrapping, thus causing oxidation or corrosion of parts. All boxes are to be placed in the upright position as indicated by the up arrows. They should not lean against a wall. The boxes should not be placed in close proximity of new cement or plaster walls. In the event that water penetrates the storage space, it is recommended that the units be unboxed to prevent internal damage. They should be stored in an upright manner, as if still in the box.

Unpacking: Care should be taken when opening the door box to prevent damage to the unit. Also, persons unpacking the box should be aware that there are loose pieces contained in the box. Care should be exercised not to lose these parts (door closer, lock cylinders with keys, shims, mounting hardware, caulking, instructions and technical data for associated components).

Transparencies: The protected side of the transparency in some instances is polycarbonate and susceptible to scratching. Care should be taken when cleaning these surfaces. Use a mixture of liquid soap and water and clean, soft clothes or sponges for cleaning. The following cleaning agents have been found to be compatible with polycarbonate: Formula 409, Joy, Palmolive Liquid, Top Job, Windex with Ammonia D. Fresh paint splashes, grease and smeared glazing compounds can be easily removed before drying by rubbing lightly with a good grade of VM&P naphtha, isopropyl alcohol or butyl cello solve (2-butoxy ethanol). Do not use butyl cello solve in direct sunlight. Using a mild automobile polish can minimize scratches and minor abrasions. Three such products that tend to polish and fill scratches are: Johnson’s Paste Wax, Novus Plastic Polish #1 & #2 (Novus Inc., Minneapolis, MN), and Mirror Glaze Plastic Polish M.G.M10 (Mirror Brite Polish Co., Pasadena, CA). It is suggested that a test be made of a sample with the product selected and that the polish manufacturer’s instruction be followed.

Important Don’ts:

  • DO NOT use abrasive or highly alkaline cleaners on polycarbonate.
  • Never scrape or scrub polycarbonate with squeegees, brushes, razor blades, or other sharp instruments.
  • Taping notices, etc to this surface should be avoided. The tape adheres to the mar resistant coating and peels the coating off when the tape is removed.
  • DO NOT use benzene, gasoline, acetone or carbon tetrachloride on polycarbonate.
  • DO NOT clean polycarbonate in hot sun or at elevated temperatures.

When cleaning glass, it is recommended that Windex with Ammonia D or other compatible household window cleaners be used to minimize streaking.

Aluminum: The aluminum trim can be cleaned similar to the transparent surfaces. Isopropyl alcohol can be used for tougher spots. Care should be taken not to scratch the aluminum surface.
