What's Happening in Glass Processing: March 2026

If you've been around the glass industry for a while, you know March is usually when things start picking up after the winter slowdown. This year feels different. Here's what I'm hearing from the shop floor and the supply chain.

1. The Tempered Glass Backlog Is Real

Anyone running a tempering line right now is feeling the pinch. Orders are stacking up and lead times are stretching.

The residential market softened a bit, but commercial work is booming. Storefronts, office partitions, curtain wall-all the projects that got delayed in 2024 and 2025 are finally moving. The problem is everyone's ordering at the same time.

One shop I talked to last week said they're running 24/5 and still quoting 4 to 6 weeks on standard tempered glass. A year ago it was 2 weeks.

If you're a fabricator, hold onto your suppliers. Raw material availability is tight, especially for low-iron glass. The big float lines are running full, but allocations are getting tighter.

2. Laminated Glass Lead Times Are Worse

If you think tempered glass is bad, laminated glass is worse.

The PVB supply chain is still a mess. There's only a handful of major interlayer suppliers globally, and they're all on allocation. DuPont, Kuraray, Eastman-they're shipping, but you're not getting everything you ask for.

The workaround a lot of shops are using? Stockpiling. If you've got warehouse space, buy interlayers when you can get them. The guys who waited until they needed them are the ones sitting on empty racks right now.

Price is up too. PVB is running about 15% higher than last year. Some of that is raw material costs. Some of it is just supply and demand.

3. Ceramic Frit: The Hidden Bottleneck

Here's one that catches people off guard. Ceramic frit-the baked-on enamel used for spandrel glass, back-painted applications, and architectural details-is getting hard to source.

The major frit suppliers are backed up. Ferro, Fenzi, Torrecid-they're all running behind. The problem is two-fold: raw pigments are coming from China and Europe, and shipping is still unpredictable.

If you're specifying fritted glass, ask your fabricator what their inventory looks like. The ones who planned ahead have stock. The ones who didn't are quoting longer lead times or turning down work.

4. Digital Printing Is Finally Going Mainstream

This is the bright spot. Digital ceramic printing on glass has been "coming soon" for about a decade. It's actually here now.

The big fabricators are investing in machines from Dip-Tech (now part of Fenzi) and other suppliers. The quality has gotten good enough that architects are specifying it regularly now.

What's driving it? Short runs. Nobody wants to store screens for custom patterns anymore. With digital, you print what you need, when you need it. No screens, no minimum quantities, no storage costs.

The downside? The machines are expensive. A decent digital ceramic printer runs well into six figures. But the shops that bought them are saying the ROI is there, especially on high-margin architectural work.

5. Labor Is Still the Biggest Problem

I don't know a single glass processor who isn't struggling to find people.

Tempering operators, laminating line leads, CNC programmers-these are skilled jobs. You can't just pull someone off the street and put them on a tempering line. It takes months to train someone who knows what they're doing.

The shops that are winning the labor game are doing two things: paying better than the competition, and investing in automation. If you can run a line with two people instead of four, that's two fewer people you have to find.

But automation isn't cheap either. CNC machines, automated cutting tables, robotic handling-all of it costs money. The shops that aren't investing are falling behind.

6. What I'm Watching Next

A few things I've got my eye on:

Energy prices -natural gas is volatile right now. If it spikes again, expect float glass prices to follow. The furnace operators pass those costs through.

Tariffs -there's talk of more tariffs on Chinese glass coming into the US and Europe. If that happens, domestic fabricators get busier. But raw materials get more expensive too.

Glasstec prep -October in Düsseldorf. Every supplier is getting their new products ready. If you're going, book your hotel now. It's already filling up.
