Hasslacher Glulam
Structural glued laminated timber (glulam / BSH) — spruce lamellas finger-jointed and bonded into strong, stable beams and columns for portal frames, long-span roofs and timber or hybrid structures. Manufactured to EN 14080; stores biogenic carbon so its product-stage footprint is strongly negative.
Carbon and evidence
Product Evidence
Evidence currently held for the Hasslacher product record.
Recorded Carbon Result
A1–A3 GWP-total per m³, incl. biogenic carbon stored in the timber (EN 15804+A2), per EPD
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

Externally (third-party) verified IBU EPD; average glulam from Sachsenburg (AT). Declared per 1 m³; GWP-total A1–A3 is strongly negative because EN 15804+A2 counts the biogenic carbon stored in the timber. C3 (+752) is the incineration end-of-life scenario releasing that carbon; D (−364) is the energy-recovery credit. A4/A5/B not declared.

Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
Structural glued laminated timber (glulam / BSH) — spruce lamellas finger-jointed and bonded into strong, stable beams and columns for portal frames, long-span roofs and timber or hybrid structures.
Typical Uses
- •Primary frame
- •Long-span elements
- •Load-bearing supports
Key Performance
High load-bearing capacity for primary frame.
Specification Actions
- •Confirm FSC or PEFC certification for all timber products.
- •Request chain-of-custody documentation from supplier.
- •Confirm the current EPD covers the selected product, finish and manufacturing route.
Indicative Health & Indoor Air
Solid glued timber; verify adhesive/formaldehyde class for exposed interior use.
