The secondary research process involved comprehensive analysis of regulatory databases, industry publications, technical standards, and authoritative construction and glass manufacturing organizations. Key sources included the US Department of Energy (DOE), National Institute of Standards and Technology (NIST), American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), International Energy Agency (IEA), European Commission Directorate-General for Energy, Glass Association of North America (GANA), British Glass Manufacturers' Association (BGMA), China Architectural and Industrial Glass Association (CAGA), International Organization for Standardization (ISO), ASTM International, US Green Building Council (USGBC), World Green Building Council (WorldGBC), National Fenestration Rating Council (NFRC), European Committee for Standardization (CEN), Japan Glass Products Association (JGPA), Korea Glass Industry Association (KGIA), United Nations Environment Programme (UNEP), International Renewable Energy Agency (IRENA), and national energy efficiency agencies from key markets. These sources were used to collect energy efficiency standards data, building code regulations, glass production statistics, thermal performance benchmarks, and market landscape analysis for Low-E glass, solar control glass, tinted glass, and clear glass technologies across residential, commercial, industrial, and transportation applications.
In order to gather both qualitative and quantitative insights, supply-side and demand-side stakeholders were interviewed during the primary research process. CEOs, VPs of Manufacturing, R&D directors, and commercial directors from vacuum-insulated glass producers, glass substrate suppliers, and vacuum sealing equipment OEMs were examples of supply-side sources. Chief sustainability officers, procurement directors from real estate and construction companies, architectural specification consultants, and facilities managers from commercial building operators and refrigeration OEMs were examples of demand-side sources. In addition to confirming manufacturing capacity expansion schedules and validating market segmentation, primary research also provided information on pricing tactics, specification acceptance patterns, and the dynamics of green building certification.

Global market valuation was derived through revenue mapping and installation volume analysis. The methodology included:
Identification of 40+ key manufacturers across North America, Europe, Asia-Pacific, and Latin America
Product mapping across Low-E glass, solar control glass, tinted glass, and clear glass categories
Analysis of reported and modeled annual revenues specific to vacuum insulated glass portfolios
Coverage of manufacturers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (installation volume × ASP by country/region) and top-down (manufacturer revenue validation) approaches to derive segment-specific valuations for windows, doors, skylights, refrigeration, and automotive applications across metal, wood, vinyl, fiberglass, and composite frame materials
