Our frame finishes compliment your project

We offer a full line of glass and frame finishes to make your project really special. The information below is helpful while designing your glazed structure and our knowledgeable staff can assist with recommendations.


This information is provided as an overview.  You’ll be able to easily specify your choice in our editable specs.
Our standard frame finishes have a 10-year warranty.

Painted Frames

  • Exterior Frame Members: Fluoropolymer (Kynar) – AAMA 2605
    Standard Colors

    Bone White
    Bone White
    Medium Bronze
  • Interior Frame Member: PPG Polycron* – AAMA 2603
    White and Bronze – same as above

Custom painted frame finishes (least expensive to most expensive).  Additional production time is required.  Warranties may vary depending upon the finish chosen.
Because commercial skylights use laminated glass or polycarbonate in overhead applications,  which blocks harmful UV rays, using an expensive Kynar finish on the interior of the skylight is not necessary.

  • Standard PPG Polycron Colors – AAMA 2603

In the early 1980s when skylights, sunrooms, and solariums became popular the only glass options were single pane, double pane, or insulated glass.
Unfortunately, even though attractive,  this type of glass did not allow spaces to be heated or cooled very effectively.  Glass technology has made great advances since the 80s. Spaces with skylights and even solariums today allow nearly the same efficient heating and cooling as any other space in the building.

Our SilverCoat E-366 and Solarban 70XL are the best value in glass available. It’s manufactured especially for Crystal Structures by Cardinal Glass,  one of the premier glass manufacturing and coating companies in the world.  Our Solarban 70XL is made by Vitro (PPG) and is considered equal to SilverCoat E-366.  Based on the availability and logistics of the project we may elect to use Solarban 70XL in place of SilverCoat E-366 – both are high-performance glass options.

Benefits of our high-performance glass:

  • Clear insulated glass gives a clear view inside and out.
  • Fully tempered safety glass on each part of the glazing unit
  • Increased energy performance since the air cavity is filled with argon gas
  • Dual seals, one for moisture and one for structure
  • Bent spacers, one joint instead of four
  • 3 special silver Low-E coatings on the number 2 side of the glass
  • Up to 10-year warranty against fogging or separation
  • SilverCoat 366 and Solarban 70XL coatings are almost clear

On commercial projects, federal codes require all roof glass to be laminated. Our standard laminated glass can be combined with any of the glass above.  Our standard inboard laminate glass is 1/4″ heat strengthened with an 0.60 PVB inner layer.  Most of our competitors use a 1/4″ annealed glass with only 0.30 inner layer.
