Methodology and sourcing behind the figures and links shown above.

Residential entry doors

Estimate derived from global exterior-doors market sizing and category shares in the provided results. MarketResearchFuture reports a 2024 exterior-doors market of $124.63B; assuming residential accounts for ≈60% of exterior doors and using Principia’s breakdown showing entry doors represent ~65.6% of exterior-door volume (entry 21% of total doors vs. patio 11%), yields ~49.1B for global residential entry doors. Growth potential uses MRFR’s exterior-doors CAGR 5.23% (2025–2035) supported by HIRI’s historical CAGR ~5.1% (2020–2025) and regional estimates (US: $8B for residential entry doors, US doors CAGR 2.8–4%), so a blended CAGR of ~5.2% is applied.

Patio and folding doors

Estimated global 2025 market size ~USD 13.0B by combining published patio-door and bifold-door figures (patio doors ~USD 12.94B; bifold doors ~USD 10.99B) and accounting for overlap. Growth CAGR taken as midpoint of segment-specific forecasts (bifold ~5.8%, residential patio ~5.2%) and above broader US doors CAGR (2.8%), yielding ~5.5% for the patio + folding doors segment.

Aluminium windows and roof lanterns

Estimate uses recent market reports for global aluminium window systems as the baseline (Credence: ~USD 111.6B in 2024). Roof-window/rooflight/lantern markets (Zion, BRI) are smaller (USD ~3–4.5B) and largely overlap with broader window-system figures; a modest incremental allowance was added to reflect premium thermally-broken aluminium roof lanterns and niche premium upgrade demand. CAGR is a midpoint estimate (≈4.5%) derived from reported CAGRs for aluminium window systems/profiles and roof windows (range ~3.4%–5.9%), reflecting stronger growth potential for energy-efficient, thermally-broken aluminium products.

Architectural aluminium fenestration for commercial buildings

Primary curtain-wall market reports place aluminum curtain wall demand at roughly USD 50B (mid-2020s) with CAGRs ~8.9–9.1%. Commercial aluminum windows are reported separately (~USD 19.4B in 2025). Aggregating curtain walls, commercial windows, and additional commercial aluminium fenestration (doors, shading) yields a conservative global commercial architectural aluminium fenestration market estimate of about USD 70 billion today. Growth potential is driven by curtain-wall momentum and retrofit/energy-efficiency demand; weighted CAGR is estimated ~8.5%, consistent with major curtain-wall forecasts (8.9–9.1%) and somewhat above some window-specific forecasts.
