Kawneer's MetroView 4-SSG Lands: A Slab-to-Slab Window Wall Built for Multifamily Retrofits and 14-Foot Glass

Kawneer's new MetroView 4-SSG is a structural-silicone-glazed, unitized window wall built around a 2.5-inch sightline and 5-by-14-foot glass capacity. The system targets a gap in the market: slab-to-slab retrofits and mid-rise multifamily where curtain wall is overkill but punched openings can't deliver the daylight.

Apogee Reverses Course on Wausau: Why Spec Writers Just Got Their Behavioral Health and Historic Replication Brand Back

Apogee Architectural Metals has scrapped its 2024 plan to fold Wausau Window and Wall Systems into EFCO. For architects with active behavioral health, historic renovation, and high-performance curtain wall specs, the reversal means the brand and product line stay intact—and the INvent series stays specifiable by name.

Trump Tweaks Section 232 Tariffs Again: What the June 8 Metals Reset Means for Window, Curtain Wall, and Hardware Specs

A new presidential proclamation effective June 8, 2026, reshuffles Section 232 tariff rates on steel, aluminum, and copper—lowering duties on some equipment categories while pulling new derivative products into the 25% bucket. For window manufacturers, glazing contractors, and envelope specifiers, the changes reset the cost math heading into the second half of 2026.

Wales Adopts Home Energy Model with 1.4 W/m²K Window U-Value Limit: Triple Glazing Becomes the Practical Default

Wales has followed England in shifting from SAP-based U-value calculations to the new Home Energy Model—but with a stricter 1.4 W/m²K limiting U-value that will likely push housebuilders toward triple-glazed windows. The change forces per-window performance modeling rather than theoretical product data.

Saint-Gobain's COOL-LITE SKN 155 Lands: A Double-Silver Workhorse Gets a Performance Refresh and a Low-Carbon Substrate Option

Saint-Gobain Glass has launched COOL-LITE SKN 155 and SKN 155 II, the next-generation replacement for the widely specified SKN 154 line. The new double-silver solar control coating brings refined aesthetics, 50% light transmission with a 27% g-value, and availability on the ORAÉ low-carbon substrate—giving spec writers a drop-in path to lower embodied carbon without retooling façade design.

NAFS-26 Is Out: FEMA-Driven Secondary Designator Goes Mandatory—What Spec Writers and Manufacturers Need to Do Now

The 2026 edition of the North American Fenestration Standard has landed, and while most of the document is stable, one change has real teeth: the previously optional secondary designator is now mandatory, driven by FEMA and the Florida Building Commission's concerns over water intrusion in hurricane-prone regions.

LionGlass Heads to the Float Line: Vitro and Penn State Aim to Cut Architectural Glass Carbon in Half by 2028

Vitro Architectural Glass has committed to a multi-year R&D push with Penn State to commercialize LionGlass—a patent-pending formulation that lowers melting temperatures by 400°C, eliminates carbonate raw materials, and delivers up to 10x the crack resistance of conventional float glass. For specifiers wrestling with embodied carbon, this could be the most consequential float glass development in a generation.
