Why replace factory glass or other plastic windows with a SHIELDS® Windshield?

With a SHIELDS® WINDSHIELD you get the FORM ~ FIT ~ FUNCTION of OEM glass with the Increased Safety ~ Durability ~ Performance of Formed & Coated Polycarbonate. To begin, we cut and form our windows using an exclusive polycarbonate sheet. We duplicate the OEM glass (including hardware mounting holes). Then we mill the edges (as needed) and holes so that the original hardware can be used from your existing glass application no matter what thickness you need (1/4”, 3/8” or 1/2”).

Finally, we post-coat in-house with our proprietary SUPERCOAT™. This gives the polycarbonate nearly the same level of abrasion resistance as glass. With our coating, you can still use your windshield wipers and have worry-free cleaning! Our coating also prevents UV damage and hazing.

Advantages of SHIELDS® vs Glass and other plastic windows:

• 260x++ TIMES STRONGER
• 1/2 THE WEIGHT
• OPTICALLY CORRECT
• DROP-IN REPLACEMENT – No extra hardware needed!
• ABRASION-RESISTANT – Still use your wipers!
• INCREASED LIGHT TRANSMITTANCE
• DECREASED SUMMER HEAT GAIN
• DECREASED WINTER HEAT LOSS
• REDUCED NOISE

Many people refer to polycarbonate as Lexan™ and Makrolon® which are brand names of polycarbonate, or plexiglass which is acrylic. Others may refer to polycarbonate as, safety glass, demo door, and other forms of glass.

TINT DISCLAIMER: Our Tint windows are 50% LTM. The material itself is tinted. We recommend you do not do after market tinting on our windows as our proprietary SUPERCOAT™ chemistry refuses adhesive materials like tinting, films, decals, etc., meaning the film will eventually peel off. Our SUPERCOAT™ is there to protect the window from abrasion from windshield wipers, cleaning, brush, etc.
