Here’s to another productive week on the forum. Looking forward to more insightful conversations and shared expertise.
We’ve been swapping to warm-edge spacers with recycled-content aluminum frames — saw about a 10% embodied-carbon drop on a small clinic, and setting was quicker since the units stayed truer (like finding level on the first try). Small caveat: confirm coating lead times and “ask for the EPD” up front, @maya_r; anyone tried vacuum IG on retrofits yet?
On a clinic job, we dropped the outer lite from 6 mm to 5 mm after rechecking wind loads and used a double‑silver low‑e; that shaved about 8% off the glazing package’s embodied carbon with no hit to schedule… Caveat: the GC wanted triples, but the extra weight forced heavier frames/anchors, so the LCA favored the tuned double — pull EPDs in EC3 to compare: EC3. @Luis, your spacer tweak pairs nicely with this; just make sure the frame doesn’t become the hidden carbon hog.
Last week I cut unique lite counts by about 30% with a quick Bluebeam layout pass; fabricator pulled from stock, we skipped an extra delivery, and both install time and upfront footprint dropped. I’ve also started comparing sealant/spacer EPDs in EC3 — the spread is wild — @NoraK: one silicone came in nearly 2x higher than another with no cost change (EC3 - Building Transparency). Small caveat: the lower-impact pick sometimes adds a week to lead time.
Quick win: nudge module widths to the fabricator’s stock sheet breakouts; we shifted a lobby grid 25 mm to hit 60 in/96 in multiples and their yield jumped about 8%, scrap bin stayed half-empty. As the OP said about efficiency and accuracy, this takes five minutes in your layout — ask @shopfab_jules for a “yield map” or skim https://www.glassonweb.com/article/optimizing-glass-cutting-yield. Just watch mullion sightlines and hardware backsets so the tweak doesn’t bite you later.
I’ve found adjusting our glass sizes to fit standard module widths can really streamline the fabrication process. When we shifted some design aspects like that, we saw quicker turnarounds and better yield. Just a little tweak made a big difference — has anyone else had luck with that?
