Smart Alitherm 800
The heavy-duty Alitherm for larger openings and commercial use: dual polyamide thermal breaks to 1.3 W/m²K with the correct glass unit, WER A capable. Note: the 800 is not among the five Alitherm systems holding Cradle to Cradle Bronze.
Carbon and evidence
Product Evidence
Evidence currently held for the Smart Systems product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of the CAB industry-average side-hung aluminium window system (1.23 × 1.48 m, standard double glazed), per EPD-2023-0014 — a UK sector average Smart is an approved user of, NOT a Smart-specific figure. Enhanced/triple variants run to 121.
Indicator: GWP-total
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

CAB association EPD representative of >50% of the UK market — not a Smart-specific declaration; Smart’s CAB approval letter is bundled into the PDF they host. Four representative windows: side hung standard 99.2 / top hung standard 105 / side hung enhanced (triple) 117 / top hung enhanced 121 kgCO2e per m². The EPD’s own disclaimer: it "cannot be used as a guarantee of the recycled content of the actual product sold on the market" — and Smart’s published billet sources are primary smelters, so no recycled-content claim is recorded here.
