Deceuninck Heritage Flush Sash
Deceuninck’s flush casement on the Heritage 2800 platform: sashes sit flush within the frame for a timber-look elevation, in 30+ colourways including woodgrain foils with matched ancillaries. Made from PVC-U with Deceuninck’s own 45,000 t/yr post-consumer recycling loop behind the profile.
Carbon and evidence
Product Evidence
Evidence currently held for the Deceuninck product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of the industry-average PVC-U reference window (1.23 × 1.48 m, double glazed, 31.4 kg), per EPD-QKE-20220002-IBG1-DE — a QKE/EPPA sector average with Deceuninck Calne among contributors, NOT a Deceuninck-specific figure. Triple glazed: 96.3.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.
