Custom Manufactured Glazing Products in North Bay, CA

When the spec calls for fire-rated separations, opacified spandrel, oversized custom IGUs, or shaped lites that catalog stock can't deliver, the project needs a specialized glazing contractor — not a distributor. B & L Glass sources these high-performance products from trusted fabricators to custom-build, frame, and install advanced architectural assemblies, serving Sonoma, Napa, and Marin counties for 65+ years. Fire-rated assemblies, spandrel panels, custom-shaped lites, ceramic-frit and silk-screened patterns, custom glass walls/conference rooms and offices, custom IGUs, and special glazing for skylights and atriums — all expertly engineered, framed, and installed by our team. Drawings reviewed in person, samples on the bench, shop drawings issued, and systems built and installed on your project's timeline.

Why Architects and GCs Choose Custom-Manufactured Glazing

Catalog stock covers the easy 80%. The remaining 20% — unusual openings, performance pulled tight to a Title 24 envelope, fire-rated separations, opacified spandrel courses on a curtain-wall infill — is where custom fabrication shows up on the drawings.

Custom-manufactured glazing gives the design team three things off-the-shelf can't deliver. Design freedom — radius cuts, oversized lites, ceramic frit and silk-screen patterns, opacified panels — so the glass carries the architectural intent rather than forcing a workaround. Performance to spec — U-value, SHGC, VLT, and fire ratings tuned to what the envelope and code path actually require. Code compliance — fire-rated assemblies and safety glazing built to the exact rating the drawings call out, not the closest substitute on a distributor's shelf.

The fourth advantage is local. B & L 's Santa Rosa shop sits between a residential glazier (no real fab capability) and a high-rise mainland fab house (long lead times, no design-assist that doesn't ride a rep). For North Bay projects, that lane is the moat — drawings reviewed in person, samples on the bench, fabrication on a turnaround that fits the GC's schedule.

Custom Glazing Products We Fabricate

The B & L custom-fab catalog covers the architectural glazing scope most North Bay commercial and mid-rise mixed-use projects need:

01

Fire-rated glass assemblies

20-minute through 90-minute ratings, with 2-hour assemblies where the application supports it. We build with Pilkington Pyrostop and Pyroshield families for code-driven separations, doors, sidelights, and borrowed-light openings.

02

Spandrel panels

back-painted, ceramic-frit, and opacified spandrel for floor-line concealment and curtain-wall infill. Color-matched to the vision lite or specified independently per the architect's elevation.

03

Custom-shaped lites

radius-cut, trapezoidal, triangular, and irregular openings for unusual geometry, gable ends, and non-orthogonal facades.

04

Ceramic-frit and silk-screened patterns

solar control, bird-friendly, branded, or purely decorative; specified per panel or per elevation.

05

Custom fabricated wall panels for tenant improvement

shop-built panels delivered ready-to-install on TI timelines, so the GC's interior schedule isn't held hostage by glass.

06

Custom IGU configurations

non-standard sizes, specialty coatings, warm-edge spacers, and triple-glaze builds where the energy spec calls for them.

07

Special glazing for skylights and atriums

laminated overhead glass and structural performance to spec for daylit lobbies, atriums, and overhead vision.

08

Specialty-trade fabrication

museum and exhibit glass, medical imaging glazing, hospitality and cultural-institution one-offs that don't fit a catalog SKU.

Glass Substrates, Coatings, and Performance Options

  • Custom fabrication is a substrate-and-coating decision before it's a fabrication decision. We work across the full architectural substrate range — standard clear, low-iron (Starphire-style) where true-clear matters, tinted, reflective, and patterned — paired with low-E coatings (single, double, or triple silver), solar-control and anti-reflective layers, and self-cleaning surfaces where the application warrants.
  • Substrates and coatings come from established sources Vitro (formerly PPG) for flat-glass and coated stock, Cardinal for IGU substrates and coating systems, Pilkington for fire-rated lines. Performance specs (U-value, SHGC, VLT) are tuned to the project's energy envelope rather than picked off a single sheet. For laminated builds, we carry PVB and SentryGlas-style interlayers, plus decorative interlayers (color, frit, fabric) when the design intent calls for it. Code-driven assemblies reference ASTM E119 and NFPA 252/257 for fire-rated separations and ANSI Z97.1 for safety glazing — light touch on the page; full detail in the spec.

Where Our Custom Glazing Products Are Used

Custom-fabricated glazing shows up across nearly every commercial project type B & L touches in the North Bay:

  • Mid-rise commercial and mixed-use up to 4 stories storefront-over-residential, multifamily, and small office buildings where catalog glass can't hit the spec or geometry.
  • Tenant improvement Custom fabricated wall panels and partition glass delivered on TI timelines so the GC's interior trades stay on schedule.
  • Hospitality and wine country tasting rooms, restaurants, hotels, and resort architecture where glass is part of the brand experience.
  • Cultural institutions and specialty trades museums, galleries, exhibit cases, and medical imaging facilities with non-catalog requirements.
  • Architectural residential large-format custom IGUs and oversized lites for high-end custom homes built by North Bay architects and custom-home builders.
  • Skylights and atriums overhead and structural glazing on commercial and architectural-residential projects across Sonoma, Napa, and Marin.

04

Inspect & Schedule Install.

Quality inspection on every piece — edges, hardware, and finish — before scheduling your install at your convenience.

05

Install & Final Payment.

A B & L crew installs end to end, walks you through operation and care, and collects the final balance — backed by our "We Make It Right" guarantee.

Why Choose B & L Glass for Custom Architectural Glazing

For 65+ years, B & L Glass has been the North Bay's in-house custom architectural fabricator — the lane between a residential glazier and a high-rise mainland fab house. We hold a 4.8★ Google rating, CSLB License #1058949, and the kind of mid-rise mixed-use scope (up to 4 stories) that local glaziers don't carry and national fabricators don't bother quoting.

The combined moat is simple. Our Santa Rosa shop fabricates fire-rated assemblies, spandrel panels, custom-shape lites, frit-patterned glass, custom IGUs, and custom-fabricated glass walls/conference rooms and offices in-house — turnaround measured in weeks, not months, because the glass is built where it's quoted. Design-assist is direct: drawings reviewed in person, samples on the bench, shop drawings issued by the same team that will fabricate the work. National fabricators do this through reps; we do it directly, backed by the "We Make It Right" service-after-the-sale promise Jeff Rowland built the company on.

Have a custom architectural glazing spec to fabricate? Bring the drawings and the performance requirements — we'll review the scope, walk the substrate and coating options, and quote the build. 65+ years in the North Bay. In-house Santa Rosa fabrication shop.

“He Saved Me Money Instead of Upselling”

I have nothing but great things to say about the gentleman that came to do the work at my Father's house. Our sliding glass door was jammed, we called around and were told by every other place I called that they don't repair them. That I would need a new one. I got a quote from Anderson's to replace the entire sliding glass door and 5 windows (glass and frames) and boy was that ridiculous over $30k. I called B & L to replace the sliding glass door and a couple of windows that were very foggy they came out and measured and asked why I wanted to replace the sliding glass door when they could just fix it. The gentleman could have tried to upsell me to replace the glass on all my windows and sliding glass door but he didn't. In fact he saved me money by telling me they didn't replace sliding glass doors. I could have ended up going with another company and replaced the sliding glass door but he said don't do that we can fix it. They Arrived right at 8 when they gave me a window 8-9 for measurements. That is refreshing! When it came time for install the gentlemen again arrived on time, they were very professional and did great work. Fixing our sliding glass door was no easy task my father and I tried to fix it our self but was rather complicated! So glad we reached out to B & L!

Stacy from B & L was amazing to work with.

As someone who has been in customer service myself, it's never a fun call to get to change an order last minute (I'm sorry, Stacy!). Stacy didn't skip a beat. As a result, I'm leaving our interaction with positive impression and will definitely work with her again in the future.

We are so glad we worked with a trusted local company for our new windows.

The installation team of Matthew, Jeremy and Trevor was a professional, well oiled machine! They worked hard and quickly - they also worked around my work from home schedule and make things happen quickly without a lot of disruption. We are thrilled with our new windows and just wish we'd made the leap sooner. Haley and the installation team did an amazing job!

Had a 3-sided neo-angle shower enclosure installed by B & L. Looked great except there was no door stop added.

Matt and Jake came out and installed one at no additional cost in under 10 minutes. Great service and attitude! Much appreciated, guys!

“Beautiful New Windows, Sparkling Clean”

This company is fantastic! We originally decided to call for a bid due to a broken garage window (it's baseball season). The representative that came out was friendly and helpful so we decided to ask about a cost to replace an ugly old yellow window as well. They listened to my ideas about what I wanted in place of the old window, and we decided to go ahead and replace it. When the day came for installation, the crew was on time and friendly. They told us they had allotted 4 hours for the job and they completed it in half that time. By the time they left I couldn't even tell they had been there except for the beautiful new windows. Everything was sparkling clean! We are so happy with our new window and glass replacement. I will absolutely call B & L for any future glass needs.

Custom Manufactured Glazing FAQs

What is custom-manufactured glazing, and when do projects need it?+

Custom-manufactured glazing is architectural glass fabricated to a project's specific size, shape, performance, or code spec — not pulled from catalog stock. Projects need it for three reasons: unusual geometry (radius, trapezoid, oversized), performance tuned to the envelope (U-value, SHGC, VLT), or fire and safety code requirements that catalog glass can't meet.

Can B & L fabricate fire-rated glass assemblies?+

Yes. B & L fabricates Pilkington-grade fire-rated glass assemblies in 20-minute, 45-minute, 60-minute, and 90-minute ratings, with 2-hour assemblies where the application supports it. Builds reference NFPA 252/257 and ASTM E119 for the rated separation. Get a quote with the rating and opening details.

What is the typical lead time for custom-fabricated architectural glass?+

Most North Bay custom architectural glass runs 3–8 weeks from approved spec, depending on substrate, coating, and assembly complexity. Lead times beat mainland fab houses on comparable scopes because the Santa Rosa shop is local — no cross-country freight, no rep-routed change orders. Complex IGU plus frit plus fire-rated builds extend the range.

Do you offer design-assist for architects and general contractors?+

Yes. B & L runs design-assist directly out of the Santa Rosa shop — no rep network in the middle. The sequence: drawings and specs reviewed with the architect, sample fabrication produced on the bench when the spec needs to be seen before it's locked, shop drawings issued, then coordination with the install team (B & L 's crew or the GC's). In-person meetings at the shop or on site are part of the workflow, not a billable carve-out. Bring the drawings and we'll start.

Can you handle specialty glazing — spandrel panels, ceramic frit, custom IGUs, curved or shaped lites?+

Yes. The custom-fab catalog covers spandrel (back-painted, ceramic-frit, opacified), ceramic-frit and silk-screen patterns, custom IGU configurations, radius-cut and shaped lites, and specialty-trade glazing for museum, medical imaging, hospitality, and cultural-institution work. Send the drawings and we'll quote the assembly.
