Build it. Calculate it. Issue the sheet.
Build insulating units and laminates layer by layer with the maker’s own interlayers and spacers, get real performance from LBNL’s engine, and issue spec sheets in your own layout.
From layers to an issued sheet
1. Build
Layer by layer, named
Glass, Saflex®, SentryGlas®, Trosifol® and every Vanceva® color, spacers from Technoform, Edgetech, Quanex, Cardinal and more, gas fills and strength marks, with a to-scale cross-section.
2. Calculate
Real performance, every time
U-factor, SHGC, light, reflectance, UV and color from LBNL’s Windows-CalcEngine, plus an estimated STC and OITC, with a bill of materials.
3. Issue
Sheets in your own layout
Spec sheets with your logo and a verification code (Basic), your own templates and comparison sheets (Pro). Issued sheets stay exactly as issued.
4. Control
An approved catalog and change alerts
On Pro, choose what your people may build with, and get told when LBNL updates or withdraws a glass on your saved sheets.
What fabricators get
- 57 named interlayers and the Vanceva® color builder, from measured laminates in LBNL’s IGDB
- Named spacers with the maker’s colors and widths
- A warning when a low-e coating is laminated against the interlayer
- Read-only Technician seats for the shop floor, free on Basic and Pro
- Submit a glass that isn’t listed and use it right away (labeled not NFRC)
Custom laminates are calculated by GlassRef with the NFRC laminate method and checked against LBNL’s clear PVB laminates (within 0.001 on light, solar and SHGC). GlassRef never certifies a product.

Questions fabricators and manufacturers ask
Is our glass in GlassRef?
GlassRef carries every product in LBNL’s International Glazing Database, about 6,600 glazing products from 80+ manufacturers, synced weekly. If a product isn’t there, a user can submit it from the maker’s data sheet; it is labeled “Submitted · not NFRC”.
Does any manufacturer get preferred placement?
No. Equivalents are ranked on measured properties, and no manufacturer pays for placement or gets a boost.
How are laminates with named interlayers calculated?
Each named interlayer’s optics are taken from measured laminates in LBNL’s IGDB and combined by LBNL’s engine. Results were checked against LBNL’s laminates and come out within about 0.01; sheets name the interlayer maker and the source.
Can we keep our team to the products we sell?
Yes, on Pro. The approved catalog limits manufacturers, glass types, interlayers, spacers, gas fills and strengths, enforced on the server for library searches, the builder and every sheet.
What happens to issued sheets when LBNL data changes?
Issued sheets stay exactly as issued. On Pro, GlassRef lists the sheets whose glass changed, shows what changed, and lets you re-issue in one tap.
GlassRef publishes reference data and shows where every number came from. It does not test, certify or approve products; product certification belongs to bodies such as NFRC, and the design professional of record signs off on what goes into a building. GlassRef is independent and not affiliated with LBNL or any manufacturer.
