Most people choosing a sunroom spend their energy on glass, roof style, and layout. The frame finish gets decided in about five minutes near the end, usually by picking whichever color sounds closest to the house trim.
That’s a shame, because the finish is one of the few decisions you can’t change later without significant cost. It determines how the room looks against your home, how well the color holds up after 15 years of sun, and whether the frame can be repaired or matched down the road. So what colors and finishes are available for sunroom frames? Here’s the full range, what the technical specifications actually mean, and how to choose.
Two Finish Families: Painted and Anodized
Every aluminum sunroom frame finish falls into one of two categories, and they work in fundamentally different ways.
Painted finishes apply a coating on top of the aluminum. This opens up the entire color spectrum, including exact matches to your existing windows or trim, and gives you solid colors with consistent appearance across the whole structure.
Anodized finishes aren’t coatings at all. Anodizing is an electrochemical process that grows a hardened oxide layer out of the aluminum itself. Because the finish is part of the metal rather than sitting on it, it can’t peel, chip, or flake. The tradeoff is a limited palette of metallic tones.
Neither is better in general. They’re better at different things.
Painted Frames and What the Specifications Mean
Painted frames come in two performance grades, and the difference matters more than the color you pick.
Kynar (fluoropolymer), AAMA 2605. This is the premium architectural coating standard, used on exterior frame members. It resists fading, chalking, and gloss loss far better than ordinary paint, which is why it’s specified on commercial buildings meant to look good decades out. If your sunroom faces west or south and takes heavy sun, this is the finish doing the heavy lifting.
PPG Polycron, AAMA 2603. A baseline architectural coating used on interior frame members. It performs well in a protected environment and costs less. Because it never sees direct weathering, the higher UV durability of Kynar isn’t necessary indoors.
Sunshine Rooms uses that split as standard: Kynar on the exterior where the weather is, Polycron on the interior where it isn’t. It’s a sensible allocation of cost rather than a compromise.
Standard and Custom Painted Colors
The two standard painted colors are Bone White and Medium Bronze, available on both the exterior and interior frame members. These cover the large majority of projects because they sit comfortably against nearly every common trim color, and because they’re stocked, they carry the shortest lead times.
Beyond the standard pair, custom painted finishes are available. Ordered roughly from least to most expensive, the options run:
- Standard PPG Polycron colors (AAMA 2603)
- Flat black
- Gloss black
- Custom Kynar colors (AAMA 2605)
- Standard Firestone Kynar colors
Black frames have become popular for a reason. They read as modern, they visually recede so the glass and the view dominate, and they pair well with black-framed windows elsewhere on the house. Worth knowing: dark finishes absorb more heat, which is a consideration on a large south or west exposure, though thermally broken framing limits how much of that reaches the interior.
Custom colors require additional production time, and warranty terms can vary depending on which finish you select. Both are worth confirming before you commit.
Anodized Frames and Their Color Range
Anodized finishes come in metallic tones rather than solid colors. The two standard choices are Clear Anodized and Dark Bronze Anodized, both specified Class I on the exterior and Class II on the interior. Those classes refer to coating thickness. Class I is the heavier, weather-exposed grade; Class II is appropriate for protected interior surfaces.
The optional anodized range, again from least to most expensive:
- Clear anodized
- Medium bronze anodized
- Dark bronze anodized
- Black anodized
- Champagne anodized
Clear anodized reads as natural brushed aluminum and works beautifully on contemporary architecture. Champagne is a warm, subtle metallic that flatters stone and warm-toned brick.
One honest caveat: anodized color can vary slightly between production batches. For a single structure ordered at once this is a non-issue, but if you may extend the room later or need a replacement member years on, an exact match is harder to guarantee than with paint. Ask about it if future expansion is a possibility.
Painted vs. Anodized at a Glance
| Factor | Painted | Anodized |
| Color range | Full spectrum, custom matching possible | Metallic tones only |
| Standard colors | Bone White, Medium Bronze | Clear, Dark Bronze |
| Finish type | Coating on the aluminum | Oxide layer within the aluminum |
| Can chip or peel | Possible with impact | No |
| Batch matching | Reliable | Slight variation possible |
| Best for | Matching existing trim, bold or specific colors | Contemporary looks, maximum durability |
Choosing a Finish for Your Home
Three questions narrow it down quickly.
What are you matching? If your windows, gutters, and trim are already a defined color, painted frames give you the closest match. Bring a sample or the manufacturer’s color code to the conversation rather than describing it.
What’s the architectural style? Traditional homes generally suit bronze or white. Contemporary and modern homes tend to look better with black or clear anodized, where the frame reads as a thin structural line instead of a border.
How much sun does the room take? Heavy west or south exposure argues for the highest-durability exterior finish available, since that’s the elevation where color retention gets tested. Their glass options and custom sunshades work alongside the finish on those exposures.
The most reliable way to decide is to see the finishes on completed rooms rather than on a chip. The project gallery shows how each reads at full scale and in real light.
Lead Times, Warranties, and Practical Notes
Standard frame finishes carry a 10-year warranty. Custom finishes may carry different terms, so get the specific warranty in writing for whatever you choose.
Standard colors ship fastest because they’re stocked. Custom painted finishes add production time, which can matter if you’re working toward a seasonal completion date. If your schedule is tight, ask about lead time before falling in love with a custom color.
Finally, specify the finish early rather than late. It affects pricing, schedule, and warranty, and it’s far easier to settle during design than to revisit once fabrication is underway. Full details are on the frame finish options page.
So, What Colors and Finishes Are Available for Sunroom Frames?
Painted frames give you Bone White and Medium Bronze as standard, with flat black, gloss black, and custom Kynar or Polycron colors available for an upcharge and added lead time. Anodized frames give you clear and dark bronze as standard, with medium bronze, black, and champagne as options. Painted wins on color matching and range; anodized wins on durability and a finish that cannot chip.
