Building Code H1 · Energy efficiency
H1 addresses energy performance, not a nationwide double- or triple-glazing prescription. The 2025 compliance-document update retains the overall required efficiency and insulation level.
Glazing implications
Window performance depends on the glazing, frame and edge construction. Read the selected design and compliance route before deciding whether double or triple glazing is appropriate.
Industry signal · company source
AGP describes a purpose-built factory exceeding 40,000 square metres, automated glass shuttles, robotic spacer application and IGU production with minimal human contact. This describes existing plant capability, not a measured H1-driven growth rate. Company source
From specification to manufacturing
Translate the approved window specification into actual pane build-ups, mass, contact faces and IGU production-station requirements.

Victoria · NCC / 7-star homes
New homes must meet 7-star NatHERS and Whole of Home requirements. Victoria explicitly states that double glazing is not mandatory; orientation and the overall design matter.
Glazing implications
A whole-home rating can be reached through different design choices. Glazing selection also depends on orientation, shading and the project’s thermal-performance assessment.
Policy & industry context
The Victoria source explicitly says double glazing is not mandatory. Read state adoption requirements separately rather than treating one state’s rules as a single national glazing specification.
From specification to manufacturing
Confirm the selected glazing and solar-control specification before reviewing coated-glass contact and production-line components.

Building Energy Efficiency Act · Expanded compliance
Expanded new-building compliance concerns envelope and primary-energy performance. The selected glazing depends on the building specification; separate renovation subsidies have their own product and application conditions.
Glazing implications
Low-E glass and insulating units may form part of the selected envelope specification. Building-level performance is different from the thermal value of one pane or window.
Industry signal · company source
NSG announced new sputter-coating equipment at Chiba, with trial production to follow and capability for glass up to 6 by 2.5 metres. The release reported installation; later sales and output are not verified here. Company source
From specification to manufacturing
Review exact Low-E products, accessible contact faces and surface inspection before selecting suction cups or covers.

United Arab Emirates
Dubai · Al Sa’fat Green Building System
Al Sa’fat requires new buildings to achieve Silver Sa’fa. Gold and Platinum add higher requirements. The rating does not establish a universal glass pane count.
Glazing implications
Solar-control performance can shape the glazing specification. Establish the exact coating, glass build-up and panel size rather than inferring a pane count from the building’s rating.
Policy & industry context
Silver is the minimum baseline identified by Dubai Municipality; Gold and Platinum represent higher tiers. This is Dubai coverage, not a statement of rules across all UAE emirates.
From specification to manufacturing
Confirm solar-control glass and actual panel dimensions; assess coated-surface contact and the complete handling task.

Europe
European Union
Energy Performance of Buildings Directive · EU/2024/1275
The recast EPBD supports building renovation and zero-emission buildings. Member States choose nationally appropriate measures; window obligations must be checked in the applicable national law.
Glazing implications
Renovation and building-performance measures can affect window specifications. The obligation for a particular project must be established in the relevant national implementation.
Policy & industry context
The national transposition deadline was 29 May 2026. That deadline does not prove that every Member State has completed implementation, or that one window specification applies throughout the EU.
From specification to manufacturing
Track national renovation measures, then evaluate the confirmed glazing specification and related processing requirements.
2026-11-06
United Kingdom
England · Future Homes and Buildings Standards
The 2026 regulations introduce updated energy and emissions requirements with future commencement. They must not be described as an already effective UK-wide triple-glazing mandate.
Glazing implications
The selected window and glazing design should follow the requirements and transition route applicable to the project. Future commencement dates need to remain visible in specification discussions.
Policy & industry context
The 2026 regulations have been enacted with future commencement. General provisions commence on 24 March 2027; specified higher-risk-building provisions follow on 24 September 2027, with transitions.
From specification to manufacturing
Monitor project specifications and supplier readiness; future regulatory dates alone do not establish current glass orders.

United States
California · 2025 Energy Code / Title 24 Part 6
The 2025 Energy Code applies to permit applications from January 2026. Building-performance compliance must be distinguished from voluntary window certification and from pane-count claims.
Glazing implications
Keep whole-window performance separate from glass-only values. A specification using triple glazing may have a conventional center pane or a thin-center-pane design, with different workpieces to handle.
Industry signal · company source
Alpen reported two high-speed automated glass lines and a collaboration using Corning thin glass as the center pane in triple- and quadruple-pane IGUs. This is company-level investment evidence, not a national growth rate. Company source
From specification to manufacturing
Compare individual-pane and completed-IGU handling; distinguish conventional triple glazing from thin-center-pane designs.
2026-11-06
Canada
British Columbia · Building Code / Energy Step Code
The Step Code uses performance-based energy assessment. Higher local steps require local verification; this is not a Canada-wide instruction to use triple glazing.
Glazing implications
Cold-climate projects can use different IGU and frame combinations. Record the specified complete window and glass build-up instead of deriving a universal triple-glazing requirement.
Policy & industry context
Provincial baselines and municipal higher steps must be read together. The applicable requirement depends on building type, location and permit date; other provinces need separate review.
From specification to manufacturing
Use confirmed cold-climate IGU build-ups to review weight, supports and available suction-cup contact surfaces.

Read each source within its scope. Performance requirements do not necessarily prescribe a glass pane count. Manufacturing implications are technical interpretations, not evidence of market growth or product approval.
Read thermal-performance values in context
Ug: the glazing
Describes thermal transmittance of the glazing. It is not the complete-window value.
Uw: the complete window
Includes the window construction. Check dimensions, framing, units and the calculation or test basis.
R-value: thermal resistance
Compare equivalent constructions and units. Do not use 1/Ug as the R-value of a complete window.
