An entrance canopy is one bay. A covered walkway is sixty. That difference is the whole design problem. Decisions that barely register over a single doorway — how much the assembly weighs, how far it spans, how many supports it needs — compound across every bay of a long run until they govern the budget,…

A glass canopy is the most scrutinized twenty feet of a building. It’s at eye level, it’s the first thing anyone touches, and it’s the element most likely to be judged on appearance and remembered for performance. It’s also a roof, cantilevered over the one place a building can least afford to drip, ice over,…

“How big can it be” is the first question on almost every atrium, natatorium, and lobby project, and it doesn’t have a single answer. The honest one is that size isn’t a product limit — it’s the output of four variables working against each other. Here’s what actually governs it. The Short Answer How Big…

The words describe the same object, glass in a roof, but they refer to two different product categories with different governing standards, different engineering, and different failure consequences. Knowing which one a project needs is usually obvious. Knowing why is what keeps the wrong one from getting specified. The Core Distinction What’s the Difference Between…

Pre-engineered metal buildings are the most common commercial roof type in the country and the least forgiving place to put a skylight. The structure is optimized, the secondary framing is light, the panels move, and the whole assembly was engineered as a system before anyone drew a roof opening on it. Detailing that works on…

When a building owner calls about a leak, the skylight gets blamed first — it’s the most visible thing on the roof, directly above the stain on the ceiling. But in most cases the unit isn’t leaking. The interface is — where the skylight meets the curb, the curb meets the deck, the flashing meets…

Crystal Structures adds products in RIB SpecLink to support design professionals through product research, evaluation, and specification Crystal Structures, a leading manufacturer of glazed structures such as skylights, canopies, solariums and more, has announced that its products are now listed in RIB SpecLink, a software platform that has helped thousands of architects, engineers, and specifiers…

Daylighting systems are intended to enhance architectural spaces for decades — delivering natural light, energy savings, occupant wellness, and visual comfort. But not all translucent systems age the same way. Across schools, healthcare facilities, transportation hubs, retail centers, and civic buildings, aging fiberglass skylight systems are increasingly showing signs of optical degradation, discoloration, reduced light…

Not every commercial skylight is built for the same job. A skylight that works perfectly above a hotel atrium would be the wrong choice for a school corridor — and the system that drops cleanly into a metal roof retrofit is rarely the one specified for a custom barrel-vault entrance. Choosing the wrong category at…
