Slim-frame aluminum windows in a warm interior

Aluminum Windows · San Diego, California

Aluminum Windows in San Diego.

Thermally broken aluminum windows for San Diego builders and homeowners, glazed to the performance figures Title 24 requires and hardened against the salt air that comes with living close to the coast.

In short

California's Title 24 energy code sets the U-factor and solar heat gain numbers a San Diego window has to clear before a permit goes through, and a thermally broken aluminum frame with the right glazing package hits that mark without borrowing an inland spec. Crateworks sources that build factory-direct and confirms the Title 24 numbers before your architect submits.

Built for San Diego’s climate

San Diego falls in IECC climate zone 3B, mild by most measures, but Title 24, California's Building Energy Efficiency Standards, still sets a U-factor and SHGC ceiling that a window has to clear before plan check signs off, and that number needs to be locked at the spec stage rather than adjusted mid-review, since a late swap resets the clock on your submittal. The other local fact is corrosion: marine air drifting in off the coast pits standard hardware and finishes within a few seasons, closer to the water it happens faster. Because the weather here does not force a seasonal deadline, the schedule that actually matters is getting the glazing spec locked before Title 24 documentation goes in.

Why it suits San Diego

Timber looks right on a coastal elevation right up until the salt air works into the joinery, swelling and rotting a wood frame faster than it would inland. Aluminum does not have that problem, and a PA66 polyamide thermal break keeps the U-factor low enough to clear Title 24 without leaning on the coast's mild temperatures to do the work. Sourcing direct is what makes the upgrade path affordable: triple-pane glazing, a heavier-wall frame, marine-grade hardware that will not pit near the water. The spec climbs to meet the code; the price does not climb with it.

Container-direct delivery into San Diego County.

How it ships to San Diego: San Diego's own port handles almost no container traffic, so material comes in through Los Angeles and Long Beach and trucks down I-5, a short coastal run.

Common questions

On nearly every permitted San Diego project, yes. We spec the U-factor and SHGC to clear California's Title 24 energy standard and hand you the documentation your plan checker will ask for before submittal, not after.
Aluminum itself will not rust, but standard hardware and fasteners can pit within a couple of seasons near the water. We spec marine-grade hardware for anything within reach of the marine layer.
Send drawings or a spec and we build to it, size, operation, RAL color, glazing package, hardware. Nothing here comes off a fixed catalog.
Lock the glazing spec before your Title 24 plan-check submittal goes in, a swap mid-review resets that clock. Custom aluminum also runs on a production-plus-ocean-freight window, so ordering early protects both timelines at once.
