ConceptWall 50
A 50 mm stick-system curtain wall — the aluminium grid behind most contemporary glazed facades, capable of carrying up to 700 kg of glass per panel and available as capped, structurally glazed or structurally clamped, with a steel-beam-look variant. Thermal performance goes down to Uf 0.56 W/m²K on the insulated versions. At 108 kgCO₂e per m² of facade it is one of the heavier surfaces a project specifies, which is what makes the aluminium recycling credit at the end of its life worth reading properly rather than netting off.
Carbon and evidence
Product Evidence
Evidence currently held for the Reynaers Aluminium product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of curtain wall, essentially all fossil (108 of 108, with 0.202 biogenic and 0.0615 luluc). Module D declares a large aluminium and glass recycling credit — −41.7 if the glass is recycled, −12.3 if it is landfilled — but that sits outside the production figure and depends on what happens at demolition decades from now. Do not net it against the 108.

Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
A 50 mm stick-system curtain wall — the aluminium grid behind most contemporary glazed facades, capable of carrying up to 700 kg of glass per panel and available as capped, structurally glazed or structurally clamped, with a steel-beam-look variant.
Typical Uses
- •Glazing systems
- •Facade engineering
- •Thermal envelope
Key Performance
Supports daylight and thermal performance of the envelope, and carries wind load back to the frame.
Typical Service-Life Estimate
30 yearsGeneric estimate for early design discussion; confirm with the manufacturer.
Specification Actions
- •Verify product-specific recycled content and manufacturing energy route.
- •Use reversible fixings to support high-value metal recovery.
- •Confirm the current EPD covers the selected product, finish and manufacturing route.
