Energy efficient vintage windows
• Triple-seal integrity – Energy efficient vintage windows achieve air infiltration rates <0.8m³/m·h (EN 1026 Class 4) through silicone-free EPDM gaskets and magnetic perimeter seals, reducing HVAC loads by 32% in UK Victorian retrofits.
• Historical compatibility – Slim 28mm sightlines replicate 19th-century profiles while accommodating 44mm triple glazing for 0.68 U-value performance exceeding Passive House standards.

Energy efficient vintage windows reconcile historical aesthetics with cutting-edge thermal science through engineered steel framing systems designed for carbon-neutral preservation. These steel windows utilize aerogel-infilled thermal breaks (λ=0.015 W/mK) combined with warm-edge spacer technology to eliminate condensation risks down to -30°C ambient temperatures—critical for heritage buildings in Nordic climates where original single-pane installations caused 78% higher heat loss. Unlike PVC replicas, Energy efficient vintage windows maintain authentic muntin profiles while achieving whole-unit U-values of 0.68 W/m²K, validated by PHI Darmstadt certification across 12 European cathedral restorations since 2023.
