Market Pressures — 2026

Three forces reshaping
every glazing bid right now

01

Energy codes are tightening faster than specs are updating

ASHRAE 90.1-2022 and the 2024 IECC now require U-0.27 or better across commercial fenestration in climate zones 4 through 7 — a 23% improvement over 2019 code. Most glazing specified in current bids was designed to 2016 standards. The liability is in the spec sheet.

Supply chain disruptions have made lead times a bid variable

Between 2022 and 2025, average commercial IGU lead times fluctuated between 14 and 26 weeks depending on float glass availability. Projects that specified glazing without confirmed lead-time commitments averaged 11 days of schedule compression per delayed shipment. Pane maintains 40,000 sqft of float glass inventory on-site.

LEED v4.1 credit EA Prerequisite 2 requires documented glazing performance

Architects specifying for LEED certification now need manufacturer-certified SHGC, VLT, and U-value data submitted as part of the energy model. Generic glazing certificates don't satisfy the prerequisite. Pane ships every IGU with a serialized performance certificate traceable to the production batch.

Modern residential building with large triple-glazed floor-to-ceiling windows in grey aluminum frames
Triple-Glazed Residential

R-7.5 assemblies. Cut to dimension. Shipped in six weeks.

Our triple-pane residential line uses two argon-filled cavities and a krypton-boosted option for passive house applications. Every unit exits the tempering furnace with a measured center-of-glass U-value, not a nominal one. We cut to your dimension list, not to stock sizes.

IGU Replacement

Failing seals. Broken argon. We match your existing frame.

Facility managers replacing failed IGUs in aging towers face a hidden problem: the original manufacturer is gone and the frame tolerances are undocumented. We field-measure, fabricate to match, and ship with a 10-year seal warranty. Same-day phone support. No ticket queue.
