Slim-frame aluminum windows in a warm interior

Aluminum Windows · San Jose, California

Aluminum Windows in San Jose.

Thermally broken aluminum windows for San Jose remodels and new construction, glazed to the SHGC and U-factor limits Title 24 sets, built to match the slim sightline a mid-century glass wall calls for.

In short

Eichler-era homes across San Jose were built around floor-to-ceiling glass walls facing an atrium or courtyard, and swapping that glazing today means clearing California's Title 24 solar heat gain limit without losing the slim steel-look sightline the house was designed around. Crateworks sources thermally broken aluminum that hits both marks and confirms the Title 24 numbers before your architect submits.

Built for San Jose’s climate

San Jose sits in IECC climate zone 3C, the marine designation, but far enough up the bay and inland from real coastal exposure that the defining fact is dry, sunny days with a narrow day-to-night swing rather than fog or salt air. What that means for glazing is that solar heat gain matters as much as the U-factor Title 24 checks at plan review, since a room that faces long, direct sun most of the year will overheat on SHGC alone even with a strong U-factor. It shows up hardest in the city's mid-century Eichler homes, common through Willow Glen and Almaden Valley, where the original design ran floor-to-ceiling glass along an atrium or courtyard wall, and a modern replacement has to clear Title 24 without trading away the narrow steel-look frame the house was built around.

Why it suits San Jose

In an Eichler-style remodel the window frame is not trim, it is most of what you see, so the sightline carries as much weight as the performance numbers. Because the aluminum ships factory-direct, the low-SHGC glazing package or a triple-pane upgrade for a Los Gatos great room costs a spec line rather than a premium tier, which is what makes replacing an entire wall of glass, not just one opening, affordable inside a normal remodel budget. Send the opening dimensions and glazing pattern through /brief and we build to it.

Common questions

On nearly every permitted San Jose project, yes. We spec the SHGC and U-factor to California's Title 24 standard and hand over the documentation your plan checker will want before submittal.
That is one of the more common requests we get out of Willow Glen and Almaden Valley. Thermally broken aluminum holds the narrow sightline of the original steel frame while clearing a modern energy code the original glass never had to meet.
Yes, and it is priced as a spec line rather than a custom project fee. Send the opening dimensions through /brief and we quote the full run.
Lock the glazing spec before your Title 24 plan-check submittal goes in, since a late change resets that review. Custom aluminum also runs on a production-plus-ocean-freight window, so ordering early protects both timelines.
