Fontana Window Replacement provides professional title 24 compliance & energy documentation in Fontana, CA for residential and commercial properties across the central Inland Empire. Every replacement opening in this city answers to one document before it answers to a salesperson. Fontana sits in California Building Climate Zone 10, and the prescriptive fenestration package for that zone is a maximum U-factor of 0.30 and a maximum solar heat gain coefficient of 0.23.
Those two numbers come from Table 150.1-A of the Building Energy Efficiency Standards, and the climate zone comes from the Energy Commission's own ZIP code assignment. The 92335, 92336 and 92337 ZIPs are all Zone 10. Nothing about that is negotiable at the kitchen table, and nothing about it depends on which showroom you walked into first. Fontana is not a borderline address; the whole city sits inside one zone.
The paperwork runs in two halves. A Certificate of Compliance, the CF1R, goes in with the permit application and lists the U-factor and solar heat gain coefficient the job is promising. After the units are in, a Certificate of Installation, the CF2R, is signed by whoever did the work, under penalty of perjury, saying the glass that went in matches what was promised.
The inspector closes the loop by reading the temporary labels still stuck to the glass. That is why we tell homeowners not to peel them off, however much they want their new windows to look finished. Those stickers are the evidence. Pull them early and the field check has nothing to read, and you are into default tables or a second inspection.
The label numbers themselves have to come from the National Fenestration Rating Council or from the code's own default tables. A brochure claim is not a source. Field-fabricated glazing has to use the defaults, and the defaults are deliberately unflattering, which is a quiet argument for buying rated manufactured units rather than something assembled on site. Ask which of the two sources your quote is built on before you compare prices.
There is a second route. Where the prescriptive numbers do not work for a particular house, the performance approach models the whole building and lets one measure trade against another. It costs a modeling fee and it takes longer. It is occasionally the cheaper answer on an odd house with a lot of west glass, and almost nobody offers it, because selling a window is easier than running a model.
We will be honest about what this page is. Almost nobody searches for Title 24 windows. The people who land here have usually already failed an inspection, or they are holding three bids and trying to work out why one is four thousand dollars cheaper than the other two. Usually the answer is the glass package, and usually the cheap bid clears 0.30 comfortably and misses 0.23 by a mile.
So ask for the numbers in writing before you sign anything, from us or from anyone else. A contractor who cannot tell you the U-factor and solar heat gain coefficient of the exact unit they propose has not priced your job. They have priced a window and hoped the inspector was in a good mood. We put both numbers on the estimate, per opening, before anyone signs anything.
Our licensed and insured team brings the right materials and equipment to every job — spectrally selective soft-coat low-E glass, argon-filled insulated glass units, warm-edge stainless and foam spacers, welded multi-chamber vinyl frames, pultruded fiberglass lineals, aluminum-clad wood sash — and backs the work with a written workmanship warranty. We serve Fontana and nearby communities including Rialto, Bloomington, Colton, Grand Terrace.

Materials, equipment and how we do title 24 compliance & energy documentation
The difference between title 24 compliance & energy documentation that lasts and title 24 compliance & energy documentation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with spectrally selective soft-coat low-E glass, argon-filled insulated glass units, warm-edge stainless and foam spacers, welded multi-chamber vinyl frames, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Fontana job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in the central Inland Empire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
