Pricing starts at only $144 and is determined by size, coating & thickness of your custom window.

Coated Windows: Better Quality, Longer Lasting!

Polycarbonate is a soft material, which is how it absorbs impact. Because of this, it scratches easily. Even cleaning an uncoated window can cause scratch marks, affecting visibility.

A mar-resistant hard coating is a much better quality product with a significantly longer product life. We coat using our world-renowned high tech process.

Flexible coating applied before molding allows for easy shipping.

Permanent anti-fog coating is included at no additional cost..



  1. Do not scrub with brushes or other devices that may scratch and/or gouge your window.
  2. Avoid the use of abrasive cleaners and chemical solvents.
  3. For extreme situations, Isopropyl Alcohol (Rubbing Alcohol) is an acceptable cleaning solvent.
  4. Repel finger smudges, dirt, dust, grime and moisture with a streak and haze free finish with Five Star's Window Cleaner.

Mounting Instructions

  1. When trimming your window, always use sharp, coarse tooth jigsaw blades.
  2. After cutting, all edges must be sanded smooth to prevent fracturing.
  3. All holes must be drilled slightly oversized to avoid stressing areas; countersink all holes. Five Star's countersink bit is perfect for this job.
  4. Use machine screws with nylon lock nuts, as in Five Star's Window Installation Kit. Do not mount windows with rivets! The pressure exerted on the surface of the window during rivet installation will eventually cause fracturing.
  5. Do not overtighten! Polycarbonate windows must be able to expand and contract. Overtightening screws will crack the window around the mounting holes.
  6. DO NOT USE LIQUID THREADLOCKER (I.E. LOCTITE®) FOR WINDOW MOUNTING! It will cause stress cracking on the polycarbonate. Use only these approved sealants for polycarbonate windows:
    • 3M Ultrapro
    • Dow Corning 795
    • Momentive/GE SCS2000 SilPruf
    • 3M Super Silicone Sealant
    • Dow Corning 995
