Use slim internal wall insulation with vapor control where façades cannot change, combining aerogel plasters, capillary‑active boards, or vacuum panels behind millwork. Coordinate dew‑point modeling, moisture monitoring, and careful edge sealing to prevent hidden condensation, preserve finishes, and support healthy indoor air over every season.
Select high‑performance glazing with warm‑edge spacers and gas fills, paired to slender timber‑aluminum hybrids or steel replicas matching original sightlines. Consider secondary panes where replacements are restricted, optimizing solar control, acoustic dampening, and security without visually heavy frames or reflective distortions that betray historic character.
