The EU timber construction market faces unprecedented regulatory pressure. With EUDR compliance deadlines approaching December 2026 and building decarbonization mandates driving decisions, specifiers are evaluating engineered mass timber — particularly glulam — alongside traditional solid log construction. This guide provides developers, architects, and B2B dealers with the technical framework for informed material selection under EN 14080:2013 and Eurocode 5.
Mass Timber Market Context — EU Growth 2020–2026
European glulam market grew 8–12% annually from 2020–2025, strongest in Scandinavia, Germany, Austria, and UK. Three drivers:
- Regulatory Momentum: NZEB (Nearly Zero Energy Buildings) mandatory across EU-27 by 2030. Glulam locks CO₂ in structure for lifetime.
- Architectural Liberation: Unlike solid log, glulam enables 30–50m load-bearing spans, curved beams, multi-storey envelopes.
- Supply Chain Maturity: EU production exceeds 2M m³ annually. CNC lamination to ±2mm. Digital design integration.
Mass timber construction delivers 42–48% lower embodied carbon per m² vs concrete (198 kg CO₂eq/m² glulam vs 243 kg CO₂eq/m² steel frame).
Technical Comparison — Glulam vs Solid Log
Thermal Performance
| Parameter | 90mm Solid Log | 140mm Glulam | Advantage |
|---|---|---|---|
| U-value (timber) | 0.5–0.7 W/m²K | 0.25–0.35 W/m²K | Glulam 40–50% lower |
| U-value (twin-skin) | 0.22–0.28 | 0.15–0.20 | Glulam 30–40% lower |
| Thermal mass (kJ/m²K) | 42 | 68 | Glulam 62% greater |
| Thermal bridging | ~15% at joints | <2% | Glulam minimal |
| NZEB-ready | No (needs cavity) | Yes (as-assembled) | Glulam |
Fire Performance (Eurocode 5 EN 1995-1-2)
Charring rate 0.8–0.9 mm/min for glulam; 0.7–0.8 mm/min for solid log.
- Glulam REI 60: achievable with 89mm section (44mm char allowance per face)
- Glulam REI 90: achievable with 140–180mm sections. Post-char laminate redundancy preserves 70–80% original strength.
- Solid log REI 60: practical limit; REI 90 requires external protective cladding (+€200–300/m²)
Structural Span
Glulam GL30c: bending strength 30 N/mm². Solid log C24: 24 N/mm². For 6m residential roof span, glulam uses 25% less material. For 25m hall span, solid log requires intermediate posts every 7m; glulam enables single curved beam.
When to Choose Glulam vs Solid Log
| Project Type | Verdict | Reasoning |
|---|---|---|
| Single-storey garden building, holiday retreat | Solid Log | Cost €100–200/m² lower; simple spans (4–6m); REI 30 acceptable |
| Urban multi-storey residential | Glulam | REI 60 mandatory, NZEB compliance, open-plan spans, embodied carbon |
| Adaptive reuse, heritage extensions | Glulam | Constrained post spacing; complex geometry; REI 60 |
| Commercial spans 25–40m | Glulam | Solid log impossible at 40m; steel alternative 30–50% more costly |

3 B2B Models for Glulam
Model 1: Developer Direct (Build-to-Rent)
Conceptual design → Eurodita pre-design (free). Structural drawings via Eurodita engineer (Eurocode 5 calcs + BIM, €2k–5k fee). 35–40% dealer margin. Example: 200m² residential frame = €18k manufacturing + 35% margin = €24.3k developer invoice. Minimum engagement: 500m³/year for favorable pricing.
Model 2: Architect Specification
Architect specifies “Eurodita GL30 glulam per EN 14080, CNC precision, CE-marked.” Eurodita engineer liaison (€1–3k fee, credited). Architect commission 5–8% from builder. No direct architect-customer invoicing.
Model 3: Dealer/Distributor Channel
3-tier margin structure: Tier 1 (50–150m³/year) 25–30%; Tier 2 (150–300m³/year) 32–38%; Tier 3 (300m³+ + territory exclusivity) 40–45%. Dealer example: 180m³/year Tier 2 = €2.85M gross profit on €8.1M wholesale revenue.
Cost-Per-m² Breakdown (200m² residential frame)
| Line | Solid Log | Glulam |
|---|---|---|
| Wall elements | €7,200 (€40/m²) | €9,900 (€55/m²) |
| Roof trusses | €7,000 | €12,000 (curved CNC) |

Cost premium: €16,220 (75%). BUT: Glulam enables 20% larger usable floor area (no interior posts) = €405/m² added space. Faster assembly (3 vs 6 weeks) = €40–60/m² site labor savings. Embodied carbon 23% lower = Passive House certification bonus. True developer net premium: €6–10k over solid log for tangible advantages.
Frequently Asked Questions
What’s the difference between glulam and solid log construction?
Solid log uses single 90mm spruce logs laminated in horizontal courses. Glulam bonds thin laminations (33–45mm) vertically into engineered beams. Glulam offers superior strength-to-weight, 40–60% wider spans, better fire ratings (REI 90 naked vs REI 30–60 requiring lining), and lower U-values (0.15–0.20 vs 0.22–0.28 W/m²K). Cost premium: 50–75%.
What fire rating does Eurodita glulam achieve?
140mm Eurodita GL30 naked = REI 60; 180mm+ = REI 90 per Eurocode 5. Solid log 90mm requires protective lining to achieve REI 60 (cost €200–300/m²).
Does Eurodita glulam comply with Eurocode 5?
Yes. All designs calculated per EN 1995-1-1 (strength) and EN 1995-1-2 (fire). Design calculations + CE documentation included in order package. Local structural engineer can stamp if required.
What’s the U-value of Eurodita glulam homes?
140mm timber alone: 0.25–0.35 W/m²K. Twin-skin assembly (100–150mm mineral wool cavity): 0.15–0.20 W/m²K (Passive House certified).
Can Eurodita supply glulam to architects for custom designs?
Yes, via nominated builder/contractor. Eurodita doesn’t invoice end-customers directly. Free pre-design consultation (2–3 hours) during design development phase.
What’s the minimum order for glulam homes?
No MOQ. Single-unit projects accepted for sample/prototype designs. Standard discount tiers apply for 500m³+ annual dealer volume.
How long is the lead time for custom glulam design?
Design phase 4–6 weeks + manufacturing 3–4 weeks + logistics 3–10 days EU = 8–12 weeks total. Standard sections: 4–6 weeks.
Does Eurodita provide structural calculations?
Yes. Eurocode 5 calculations + CE documentation included in all orders. Calculated by Eurodita notified-body-verified engineer.
What about EUDR compliance for timber sourcing?
FSC-certified Nordic spruce (Lithuanian, Swedish, Finnish state forests). Full DDS documentation with supplier geolocation and deforestation-free proof. Ready for developer/dealer EUDR filing.
Can I private-label glulam homes for my brand?
Yes. White-label available for 500m³+/year dealers: custom branding on crates, CE marking with distributor name, custom spec sheets. Adds 2% cost.
What margin can glulam dealers achieve?
25–45% depending on volume. Tier 1 (50–150m³/year): 25–30%. Tier 2 (150–300): 32–38%. Tier 3 (300+ + territory): 40–45%.
