Demystify the Performance Mock-Up
A façade performance mock-up (PMU) tests how a representative façade assembly handles wind, rain, building movement, and temperature extremes. It helps the project team identify issues before the same details are built across the building. For the separate review of appearance and finishes, see our guide to the visual mock-up process. PMU testing is much […]
Visual Mock-Up Process
A visual mock-up (VMU) gives the project team a full-scale assembly to review before fabrication. The team can assess how the façade will look and how the specified materials and finishes come together. For testing how a representative assembly performs under wind, rain, and movement, see our guide to façade performance mock-up testing. Done well, […]
WHTB Now Covers the Unitized Facade Chain
Most people in the glass business never see the inside of a facade factory. They sell glass, they discuss specifications over email. But the moment aluminum meets glass and becomes a unitized panel — the moment a building’s skin is actually assembled — that happens somewhere most of us have never stood. From the last […]
What the TAGG Collapse Tells Us About Canadian Construction
On October 24, 2025, TAGG Industries (WHTB’s client) — a glazing and building envelope company that had operated for nearly 30 years — filed for bankruptcy. TAGG was not a struggling startup.

WHTB Glass USA Is Now a Guardian Select Fabricator
There is a short list of glass fabricators in North America that architects and specifiers trust by name. Not because of marketing — because their products carry a certification that architects can put directly into a specification and have it accepted without question. As of July 20, 2026, WHTB Glass is on that list. We […]
The Glass Behind the Ice Cubes Cultural Center
A monumental sculpture that would read as a natural phenomenon — something that looked less like architecture and more like something that had formed overnight, the way ice does. The Xinxiang Cultural Tourism Center in China, designed by Zone of Utopia and Mathieu Forest Architect with structural engineering by Arup Group, needed to become the […]
Bending Glass in Three Dimensions: Inside WHTB’s Ginza Project
Stand at the corner of Ginza’s main shopping street and look up. The facade above you doesn’t sit flat against the building: it curves outward, folds back in, catches the light differently depending on where you’re standing https://www.tiffany.com/stores/en/japan/tiffany-ginza-8075 From a distance it looks like a single fluid surface. Up close, it’s hundreds of individual glass […]
Where Is Your Glass Coming From? The Tariff Question Every Project Manager Should Be Asking
Here’s a story from a client in eastern Canada. He had a 30,000 sq.ft project to complete, and 200 pieces IGUs were needed on site in 4 weeks. The answer he gets from the previous supplier: ETA 12~14 weeks, and prices subject to material pricing change accordingly. The IGUs were being fabricated overseas. The raw […]
Bird-Friendly Glass Goes Mainstream: ASHRAE 189.1 Addendum o Is Now Law
Bird collision happens 2 billion times a year across the U.S from buildings. Most of the collisions happen in the first 30 meters off the ground, where the glass is closest to the trees and street-level plantings. The construction industry has known this for a long time. And for most of that time, doing something […]
