Aluminum Windows in Los Angeles.

Thermally broken aluminum windows for Los Angeles new builds and remodels, sized for the wall-to-wall glazing a hillside or canyon lot calls for and glazed to clear Title 24 without a smaller opening.

In short

Los Angeles building departments run Title 24 energy calculations off the actual glazing spec you submit, and on a hillside lot with floor-to-ceiling openings toward the canyon or the coast, a low U-factor thermally broken aluminum frame is what gets that calculation to pass without shrinking the glass. Crateworks sources that frame factory-direct and hands over the performance numbers before your architect's Title 24 submittal goes in.

Built for Los Angeles’s climate

Los Angeles sits in IECC climate zone 3B, mild on paper, but Title 24, California's Building Energy Efficiency Standards, sets a U-factor and solar heat gain ceiling that scales with how much glass is in the wall, and a canyon or hillside house built around view glazing runs that math harder than a standard elevation does. The other local fact is heat, not humidity: inland-facing rooms in the foothills and canyons take direct afternoon sun through large openings, and a high-SHGC assembly turns that view into a greenhouse. Because nothing here forces a seasonal buying window, the deadline that matters is locking the glazing spec before Title 24 documentation goes into plan check, since a late change resets that review.

Why it suits Los Angeles

A production home builder can spec a standard window in a standard opening. A custom house built around a canyon view or a hillside sightline cannot, the glazing is often the largest single line item on the elevation, and it needs sizing, mulling, and specification as one continuous run rather than assembly from stock units. Sourcing that direct is what keeps a wall of glass affordable at a custom size: a PA66 polyamide thermal break to hit Title 24's numbers, low-SHGC glazing for the inland sun, built to the exact opening an architect drew rather than the nearest stock size.

Common questions

On the large majority of Los Angeles submittals, yes. We spec the U-factor and SHGC to the numbers your project needs and hand over the documentation your plan checker asks for before the submittal, not after.
That is most of what gets ordered here. Send the architect's elevation and we spec one continuous mulled system sized to the exact opening, not a series of stock units butted together.
Aluminum itself does not fade or degrade under UV. The glazing package is what does the work against heat gain, and we spec that package to the exposure your opening actually faces.
Lock the glazing spec before your Title 24 plan-check submittal goes in; a late swap resets that review. Custom aluminum also runs on a production-plus-ocean-freight window, so ordering early protects both timelines.
