Factory-Direct Know-How
We spent years installing OKNA windows direct from the manufacturer. We know these frames from the factory floor up — how they're built, and exactly how they should go in.
The Skyline standard
Why homeowners choose Skyline
The short version: factory-direct OKNA experience, one fully insured crew, and a lifetime transferable warranty. The long version is below.
Factory-direct roots
We didn't learn these windows from a catalog.
Before the Skyline name went on the van, Sergii and the crew spent years installing OKNA windows direct from the manufacturer. Not a few seasons — years of nothing but these frames, in every style, in every kind of wall.
That kind of repetition teaches you things a brochure can't. We know what's inside an OKNA frame — the chambers, the interlocks, the way the glass seals — because we've handled these windows from the factory floor up. We know how each style behaves in an opening, and exactly what a perfect install looks like when the trim goes back on.
That knowledge is now the company standard. Every window we set — and every patio door — goes in to the same factory spec we learned the trade on, on homes and commercial jobs alike. No shortcuts, because we'd know.
The full list
The whole standard, on one page
Part product, part crew. The OKNA lines bring the numbers — we bring the install they were engineered for.
One Crew, Fully Insured
The same experienced crew shows up to every job, and every job is fully insured. You'll know who's in your home — and they've worked together for years.
Lifetime Transferable Warranty
OKNA covers frame, sash, glass seal, and hardware for life — including accidental glass breakage — and the warranty transfers to the next owner of your home.
Energy Bills, Noticeably Smaller
U-factors as low as 0.17 with triple-pane, dual-argon, warm-edge glass. The difference shows up in your heating and cooling bills every month, all year.
Quiet, Draft-Free Rooms
Multi-chamber frames, tight interlocks, and air-infiltration ratings as low as 0.01 keep drafts and street noise outside where they belong.
Clean Work, Documented
Floors covered, furniture protected, every scrap hauled away — and a photo report of your finished openings. Our gallery is those reports, unedited.
ENERGY STAR & Rebate-Ready
ENERGY STAR rated glass packages are available across the lineup — ask about current utility rebate programs at your estimate.
The paperwork that matters
A lifetime warranty that actually means lifetime.
Plenty of window warranties shrink the moment you read the fine print — prorated coverage, glass excluded, void when the house sells. OKNA's doesn't.
The OKNA lifetime transferable warranty
Frame, sash, glass seal, and hardware are covered for as long as you own your home — and accidental glass breakage is included, which almost nobody else puts in writing.
If you sell, the warranty transfers to the next homeowner. That's a real line item when the house goes on the market, not just peace of mind.
We register it for you at the final walkthrough — and because we install to OKNA's own spec, the coverage starts on solid ground.
- Frame Covered for life — the structure that holds everything true.
- Sash Covered for life — the moving part that takes the daily wear.
- Glass seal Covered for life — if a pane ever fogs between the glass, it gets replaced.
- Hardware Covered for life — locks, balances, and tilt latches included.
- Accidental glass breakage Included. A stray baseball is a phone call, not a bill.
- Transfers when you sell The coverage follows the house to the next homeowner.

The crew
One crew. The same faces, every job.
We don't hand your house to whoever's available that week. You get the crew that's done this together for years — start to finish.
-
Fully insured, every job
The crew that measures your openings is the crew that installs them — experienced, insured, and accountable to one name on the door.
-
Your home, treated like ours
Floors covered, furniture protected, openings closed up the same day, and every scrap hauled away before we pull out of the driveway.
-
A photo report at the end
We photograph every finished opening and hand you the report. Our project gallery is built from those same photos — nothing staged.
