GlaziersEdge Knowledge tools 7

• list_topicsList the 32 topics in the commercial glass & glazing knowledge base (glass types, safety glazing codes IBC 2406, storefront/curtain wall, energy codes IECC/ASHRAE 90.1/Title 24, fire-rated, hurricane/impact, wind load ASTM E1300, butt-glazed partitions, railings, sealants, testing, specs, warranties, discontinued products, glass performance data, aluminum system cross-reference, budget pricing). Returns topic numbers, titles, one-line summaries and UNVERIFIED counts. Call this first if you are unsure which topic covers a question. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
• get_topicRead the full text of a knowledge-base topic, or a single section of it, with tables and verification tags intact. Use after list_topics or search_glazing_knowledge when you need the complete context (e.g. a whole code table). `topic` accepts a number (30), 'T30', 'Topic 30', or a title phrase ('butt glazed'); `section` accepts a section id like '30.4', 'sources', 'key', or a heading phrase like 'summary table' or 'bid-day checklist'. Long topics are paged: follow the continue_from hint. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
• search_glazing_knowledgeKeyword search (BM25 relevance ranking) across all 32 topics; returns the best-matching sections with cited snippets (topic + section id), relevant tables, and the verification tags present. Best for free-text questions: code requirements ('IBC 2406 hazardous locations', 'IECC 2021 zone 2 SHGC'), sizing rules ('max size 1/2 tempered butt glazed'), definitions ('LSG', 'heat soak'), estimating red flags, lead-time drivers, testing standards. Use specific technical keywords. For numeric glass makeup data use lookup_glass_performance; for product equivalents use cross_reference_glass / cross_reference_aluminum_system; for budget $ use budget_price_range. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
• lookup_glass_performanceFilter manufacturer center-of-glass performance data for 1 in. insulating glass units: Vitro (Solarban 60/70/72/90/R67/R77/R100, Sungate 400, Solarcool, Vistacool on Clear/Starphire/Acuity/Solexia/Atlantica/Azuria/Solarblue/Pacifica/Solarbronze/Optigray/Solargray/Optiblue/Graylite II; 145 makeups), Guardian SunGuard (SNX 62/27, SNX 51/23, SNE 50/25, SN 68, SN 54, SNR 50/43/35 on UltraClear/Clear/Green/CrystalGray/Gray) and Viracon (VNG-5024, VNG-4022, VNE-53, VRE-4725, VRE-4423 by substrate). Returns VLT, exterior/interior reflectance, U (air/argon), SHGC, LSG, catalog status and tags. Filter by maker, product, substrate, or limits (e.g. max_shgc 0.25 to meet IECC CZ 2). Old names like 'Solarban 70XL' or 'Solarban 67' are mapped to current names. Values are COG, not NFRC whole-product ratings. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
• cross_reference_glassGiven a glass coating/product (e.g. 'SNX 62/27', 'Solarban 70', 'SN 68', 'VNE-53', or an old name like 'Solarban 70XL'), return equivalents from other makers with a match rating (Close / Approximate / Not supported by the numbers). Uses (1) the KB's Guardian↔Vitro chart with tested deltas (Topic 32 §32.9), (2) computed nearest makeups across Vitro, Guardian and Viracon on the same substrate color family using the KB rating rule, and (3) Topic 29 renamed/discontinued notices. Use for 'or-equal' and substitution screening (e.g. 'SNX 62/27 Vitro equivalent'). Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
• cross_reference_aluminum_systemGiven an aluminum storefront, curtain wall, entrance door, window, interior or specialty framing series (e.g. 'Kawneer Trifab 451', '451T', '1600 Wall System 1', 'Tubelite E14000', 'YKK YES 45 TU', 'EFCO 403', 'Trifab 400'), return the equivalent series from Arcadia, OBE, Kawneer, Tubelite, EFCO/Wausau, YKK AP, CRL-U.S. Aluminum and Manko for the same family (54-row Topic 28 cross-reference), with basis (face x depth, glazing plane, thermal), Verified/Flagged status, notes, and Topic 29 discontinued-series notices. Equivalent does not mean identical: always check depth, plane, glass thickness, thermal tier, performance. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
• budget_price_rangeReturn 2026 US installed budget SELL price ranges from an experienced commercial glazing estimator ([Expert]) for a scope item: storefront, curtain wall, windows, all-glass walls/doors, folding walls, skylights, fire-rated glass/framing, entrance doors and operators, automatic sliders, glass handrails, mirrors, films, ballistic/storm-shelter glazing, sunshades, mock-ups. Units per SF, LF, each, or LS. Budget/sanity-check use only, never for bids; ranges vary by region, scope and market. Optionally include low-reliability public cross-checks. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.
