Glulam Wall Thickness Guide: 88mm to 220mm Explained for B2B Partners
Eurodita B2B Manufacturing Partner
For B2B timber dealers, recommending the correct glulam wall thickness is one of the most consequential decisions in any project. Too thin and the structure underperforms thermally. Too thick and the customer overpays for performance they do not need. The right specification matches the building’s intended use, the local climate, and the regulatory environment of the target market.
Eurodita manufactures four public glulam wall profile routes, each specified according to the project brief and selected build-up. This guide explains every option from 88mm to 220mm, helping partners recommend with confidence and position their product range across market segments.
All profiles are manufactured from Northern European timber at Eurodita’s Kaunas production facility, CNC-machined to the approved drawings using Hundegger (DE) equipment, with tolerances confirmed for the specific product, and kiln-dried to 12-14% moisture content in Nardi (IT) kilns. Production lead time for glulam structures is confirmed per order in the written quotation.
Understanding Glulam Profiles
A glulam profile is expressed as thickness × width, for example, 135mm × 260mm means a 135mm wall thickness with a 260mm log width (the visible face height of each laminated log in the wall). The thickness affects thermal performance, structural capacity, and acoustic insulation. The width determines wall appearance, joint frequency, and aesthetic character.
Thicker walls give the wall element a lower U-value (lower thermal transmittance), because the thermal resistance of solid timber increases with its thickness. The energy performance of the finished building, though, depends on the complete envelope, not on the wall thickness alone.
Structurally, glulam enables longer spans without intermediate columns compared to solid log construction. Lamination spreads natural defects (knots, shakes) across several layers, so glulam is more uniform than solid timber of the same size and typically moves less. This stability is why glulam is often reviewed for larger accommodation, holiday-park and residential-intent projects, subject to the confirmed specification and local authority requirements.
Eurodita produces approximately 1,800-2,000 bespoke timber structures per year, with glulam output reported separately, alongside approximately 12,000 standard cabins. Partners across multiple markets use these four profile routes for garden offices, accommodation-style projects, glulam houses and larger project-specific timber structures.
88mm, 135mm, 180mm and 220mm Glulam Routes
Eurodita engineered wall profile routes should be listed as 88mm, 135mm, 180mm and 220mm. A 70mm profile belongs to the standard solid-log cabin range.
Specification note: engineered wall briefs normally begin at 88mm. Standard solid-log 70mm cabins can still be suitable for garden, leisure and bespoke cabin briefs, depending on the full specification and intended use.
Technical review: wall thickness alone does not confirm year-round, residential or high-performance suitability. The full wall, floor, roof, glazing, insulation, airtightness, services and local-authority route must be reviewed for each project.
Dealer positioning: use 70mm as a standard solid-log cabin route where appropriate. Use 88mm, 135mm, 180mm or 220mm when the brief requires an engineered laminated wall profile.
88mm × 260mm, Residential Standard
The 88mm × 260mm profile is the first in Eurodita’s range to feature the full 260mm width, producing a substantial wall presence that communicates quality and permanence. This is the threshold where Eurodita begins its public engineered-glulam wall profile routes.
Recommended applications: holiday homes, granny-annexe briefs, mobile-home projects, holiday-park accommodation and commercial hospitality cabins where the final use is checked against the destination market requirements.
Thermal review: the 88mm wall profile can support extended-season briefs when reviewed with the roof, floor, glazing, insulation and installation package. Final thermal or regulatory suitability remains project-specific.
Market positioning: this profile occupies a strategic position for dealers that need an engineered-glulam entry route. In the UK and EU, use claims should be tied to the confirmed brief, insulation package, drawings and local review rather than a blanket residential or rental-performance promise.
135mm × 260mm, Premium Residential
The 135mm × 260mm profile is a common Eurodita glulam route for larger accommodation and residential-intent briefs. It should be reviewed against the complete specification, local rules and the dealer or client team’s approval process.
Recommended applications: larger accommodation projects, multi-room holiday homes, boutique hospitality units and residential-intent briefs where a full project specification is reviewed.
Thermal review: a 135mm glulam wall can form part of a higher-specification envelope, but it does not by itself confirm residential compliance or energy performance. Review wall, roof, floor, glazing, insulation, airtightness and local authority requirements together.
Market positioning: this is a useful starting point for dealers handling larger glulam enquiries. Pricing and recommended use depend on the drawings, selected build-up, logistics and private-label commercial agreement.
180mm × 260mm, High-Performance
The 180mm × 260mm profile is engineered for markets and projects where energy performance is not merely a regulatory requirement but a primary purchasing criterion. This is the specification for dealers operating in energy-conscious markets where thermal performance drives buying decisions.
Recommended applications: colder-climate, higher-performance and architect-led projects where the full envelope is specified by the dealer, client team or appointed project professional.
Thermal review: 180mm glulam can support demanding project briefs, but final U-values and energy performance depend on the complete envelope, installation quality, services, climate and local review process.
Market positioning: Germany, Austria, and Scandinavia are the primary markets for this profile, where building energy codes are among the strictest globally. Dealers in these regions report that customers who choose the 180mm specification prioritise energy performance are less price-sensitive and more focused on lifetime value. This profile is also gaining traction in the UK as energy regulations tighten under the Future Homes Standard.
220mm × 260mm, Maximum Specification
The 220mm × 260mm profile is the thickest wall in Eurodita’s glulam range, specified where a project brief calls for the maximum solid timber wall thickness.
Recommended applications: colder-climate residential-intent projects, architectural homes and showcase buildings where the full envelope is specified by the dealer, client team or appointed project professional.
Thermal review: a 220mm glulam wall adds thermal mass, but final U-values, indoor comfort and energy performance depend on the complete envelope, installation quality, services, climate and local review process.
Market positioning: this is a specialist route for high-specification timber homes. Production timing for 220mm glulam is confirmed in the written quotation, so partners targeting this segment should raise projects early and pass the confirmed timing on to their customers.
Choosing the Right Thickness for Your Market
Market conditions, climate zones, and regulatory frameworks vary significantly across Eurodita’s partner territories. The following recommendations provide a starting point for specification decisions:
- United Kingdom: 88-135mm can support many engineered-timber briefs when reviewed with the full envelope and local requirements. Standard solid-log 70mm cabins remain a separate garden-building route.
- Germany and Austria: 135-180mm is often reviewed for larger glulam briefs. 220mm may be considered for higher-performance projects, subject to full specification and local review.
- Scandinavia: 180-220mm is preferred for the climate. Even garden buildings tend toward thicker specifications than in milder markets.
- Southern Europe: specification should be selected from the intended use, solar gain, glazing, ventilation, insulation and local review requirements.
- North America and Australia: specification depends heavily on the specific climate zone. Eurodita’s design team can suggest specification options for the project on request.
Eurodita’s design team can review a project brief and set out wall profile and specification options in the quotation, subject to technical and commercial review. Structural engineering and calculations, where a project needs them, may be sourced from specialist partners, and structural and local-authority approval remain with the partner’s project team.

Frequently asked questions
What do the two numbers in a glulam profile mean?
The first is the wall thickness and the second the log width, the visible face height of each laminated log. Eurodita's glulam profiles are 70x130, 88x260, 135x260, 180x260 and 220x260 mm. Thickness affects the structural capacity and thermal resistance of the wall element; width sets the joint frequency and the appearance of the wall.
Can a 70 mm solid log profile be specified on a glulam home model?
Yes. Any approved wall profile can be specified on any model. Solid wall profiles run 19x100, 28x100, 34x100, 44x130, 58x130 and 70x130 mm; glulam runs from 70x130 to 220x260 mm. Which profile suits the brief depends on intended use, climate and local review, and the selected profile is recorded in the written quotation.
Which glulam thickness is required for year-round residential use?
No thickness on its own confirms year-round or residential suitability. Eurodita publishes no U-values, and the finished building's performance depends on the wall, roof, floor, glazing, insulation, airtightness, services and installation together. Residential-intent briefs are reviewed as a complete specification, and the approval route stays with the dealer's or client's local authority process.
Is production timing for 180 mm and 220 mm glulam published?
No lead times are published for any profile. Production timing for each order is confirmed in the written quotation, so partners targeting the thicker profiles should raise projects early and pass the confirmed timing to their customers. Pricing is quoted in EUR excluding VAT and delivery, EXW Kaunas by default.
Does Eurodita set dealer margins on glulam homes in each market?
No. Eurodita quotes a wholesale price in the written quotation, in EUR excluding VAT and delivery, and publishes no dealer margins or resale prices. Resellers set their own pricing in their own market, and how a profile is positioned against local alternatives is the dealer's decision. Private-label quotations and drawings can carry the partner's brand, as agreed per order.
