As summer 2025 heats up, it’s time to talk windows. Specifically, custom steel-framed skylights—a solution we’ve been perfecting for years at Optimum Window.
Why now? Because when the sun’s beating down and your AC’s working overtime, the quality of your windows and skylights matters more than ever.
Let’s break it down.
Less Frame, More View
Our steel skylights are built for minimal sight lines—that sleek, modern look where glass does all the talking.
Instead of bulky framing that chops up the sky, we’ve designed these units to let in more of what you want: sunlight, open space, and calm.
Table: Sight Line Comparison
| Material | Typical Sight Line Width | OWM Steel Skylight |
|---|---|---|
| Aluminum | 2″ – 2.5″ | 1.25″ |
| Vinyl | 3″ – 4″ | Not Applicable |
| Steel (OWM) | 1.25″ | ✓ |
Comfort You Can Feel Year-Round
We’re not just building for summer. These skylights are engineered to hit the U-Values you need to stay cool in the heat and warm in the cold. That means your HVAC system isn’t doing double shifts—and your energy bill doesn’t spike.
We use thermally broken steel frames and IGUs (Insulated Glass Units) that perform as good as they look.
U-Value Performance Table
| Product Series | U-Value (Lower is Better) |
|---|---|
| RTS430 Skylight | 0.19 – 0.24 |
| 6500SB Series | 0.21 – 0.25 |
| Typical Wood Frame | 0.30 – 0.35 |
Built to Fit Your Life (And Roof)
Every home is different.
That’s why we customize skylights to your specs—in shape, size, finish, and even hardware. Want blackened steel? Or a custom RAL powder coat that matches your kitchen cabinetry? Done.
And because these units are fully welded and made from galvanized cold-rolled steel, they’re made to last decades, not years.
Let the Light In—Without the Heat
Sunlight is the point of a skylight. But if it brings glare or heat, you’ve got a problem.
We solve this with low-emissivity glass coatings that filter out UV while still letting the glow pour in.
Sustainability in Steel
If you’re thoughtful about what goes into your home, steel skylights just make sense.
We use 100% recycled steel. It’s strong, clean, and recyclable forever. That’s something vinyl and wood can’t claim.
