Glossary: the terms as Eurodita uses them
This glossary defines the terms Eurodita uses when it quotes, draws and manufactures timber buildings in Kaunas, Lithuania, in the sense Eurodita uses them. Most enquiry errors are vocabulary errors: a joinery figure copied into the wall field, or an internal size read as external. Each entry gives the working definition and links to the reference page where one exists.
The definitions are written for dealers, developers, architects and private clients of larger homes, and describe how each term is used in a Eurodita quotation, not general trade usage. Wall figures are on the wall profile reference and the scope boundaries are on what Eurodita does not do.
At a glance
Wall profile: thickness first, then height, so 44 x 130 mm is a 44 mm wall.
IV45, IV68, IV92: window and door systems, never wall thicknesses; a 35 mm wall does not exist and the solid profile is 34 x 100 mm.
External dimensions: every stated size is the outside of the wall structure; a terrace is stated as its own figure.
Twin-skin build-up: outer skin, cavity, inner skin, written 44-100-44; the cavity is a space, not an insulation specification.
Glulam log: glued laminated profiles from 70 x 130 to 220 x 260 mm; dovetail corners on 88 to 220 mm only.
EXW Kaunas: the default quotation basis; the buyer’s forwarder collects at the factory.
Private label: a product made to the partner’s specification; white label is a generic product with the partner’s brand applied.
Pilot unit: a single first unit ordered to test a route; accepted practice, but not a blanket “no minimum order”.
Which terms describe the wall?
- Solid log (wall log)
- A single machined length of Nordic spruce or pine. Eurodita machines six solid profiles, 19 x 100, 28 x 100, 34 x 100, 44 x 130, 58 x 130 and 70 x 130 mm, and any of them can be specified on any model. Wall logs are supplied untreated by default; see the wall profile reference.
- Wall profile (thickness x height)
- The machined cross-section of a wall log, written thickness first and height second, for example 44 x 130 mm. The first figure is the wall thickness a buyer sees in a model name; the second is the height of one course. Writing both prevents a joinery figure being quoted as a wall.
- Tongue and groove
- The machined profile along the top and bottom of each wall log, roof board and floorboard, where a raised tongue on one edge fits the groove of the next. Eurodita data sheets record the wall construction as interlocking tongue and groove joints.
- Interlocking corner joint
- The notched crossing at each corner where the logs of two adjoining walls overlap and lock into one another, so the wall structure holds together without a separate corner post. It is the standard corner on Eurodita solid log buildings and the joint meant when a data sheet says interlocking.
- Glulam (glued laminated timber) log
- A wall log built from several timber laminations glued together rather than one solid section. Eurodita’s glulam series is 70 x 130, 88 x 260, 135 x 260, 180 x 260 and 220 x 260 mm, the wall route for glulam homes and larger structures. Where 70 x 130 mm is meant, the enquiry states solid or glulam.
- Dovetail corner
- A corner system for glulam walls in which the log ends are cut to a tapered dovetail that locks the two walls together. Eurodita offers it on the 88 x 260, 135 x 260, 180 x 260 and 220 x 260 mm profiles and not on 70 x 130 mm. It is a corner type applied to a profile, not a profile.
- Twin-skin wall and cavity
- A wall of two equal solid log skins with a cavity between them, written outer skin, cavity, inner skin. Eurodita manufactures four build-ups, 44-50-44, 44-100-44, 58-50-58 and 58-100-58 mm. The cavity is the space the insulation occupies; the insulation is bought locally and no U-value is published. See twin-skin wall build-ups.
Which terms describe the roof, floor and dimensions?
- External dimensions
- The size of a building measured to the outside of the wall structure, stated as length x width in metres. Every dimension Eurodita states is external; a terrace or overhang is stated separately, and internal floor area is smaller by the wall thickness on each side. Footprints are on base size by model.
- Eaves height and ridge height
- Two heights recorded on each catalogue data sheet in centimetres. Eaves height runs from the base of the wall to the underside of the roof at the wall line; ridge height is the highest point of the roof. A row shows “per order” where no figure is recorded.
- Apex, pent, long-ridge and hip roof
- The roof forms named in Eurodita model titles. Apex has two slopes meeting at a central ridge. Pent has one slope. Long-ridge is the roof form named on some modern models with aluminium sliding doors; the model page and order drawings show its exact geometry. Hip has slopes on all four sides. The data sheet lists it as roof form where recorded.
- Floor bearer
- The timber members that sit on the buyer’s base and carry the floor and the wall structure. Floor bearers are impregnated as standard and supplied with the kit. The base they rest on is outside Eurodita’s scope and is confirmed for the model and site.
- Floorboard and roof board
- The boards laid on the floor bearers and on the roof structure. Eurodita’s standard floorboard is 28 mm; roof boards are recorded as 19 mm tongue and groove boards on most catalogue models. Both figures are on the model’s data sheet; open structures such as gazebos are recorded without floorboards.
- Storm brace and anchor set
- The hardware set supplied with the kit for bracing the wall structure and anchoring the building to its base, recorded as Included on every Eurodita catalogue data sheet. Fitting it is part of assembly by the buyer’s crew, and the base it anchors to is the buyer’s.
Which terms describe joinery and finishing?
- IV45, IV68 and IV92 joinery systems
- Eurodita’s own timber window and door systems, made in the Kaunas joinery shop and named by the profile depth of the frame; IV92 is the triple-glazed route. The figures 45, 68 and 92 are never wall thicknesses: a “68 mm cabin” has IV68 joinery. See Eurodita windows and Eurodita doors.
- Double and triple glazing
- Joinery options, not building options. Catalogue data sheets record most windows and doors as double-glazed timber joinery in a standard or an insulated profile, with single glazing on some small garden buildings. Triple glazing is supplied through the IV92 system. Glazing is specified on the joinery line of an enquiry and confirmed in the quotation.
- Aluminium sliding system
- A sliding door system in aluminium that Eurodita buys in from a specialist supplier and integrates into the building, as on the modern log cabins with aluminium sliding doors. It is the one joinery item Eurodita does not make itself; timber sliding and bifold doors are Eurodita’s own.
- Impregnated and untreated
- Two default finishes for two components. Floor bearers are impregnated as standard because they sit on the base; the treatment route is stated in the order documentation. Wall logs are supplied untreated by default, so the buyer or end customer applies the chosen stain or paint after assembly. Neither default changes unless the quotation states otherwise.
- Factory painting
- An optional finishing service in which wall components are painted at the factory before dispatch. It is offered with limited capacity and is never the standard finish; on glulam it is an extra service. A request goes on the finish line of the enquiry, and whether it can be accepted is confirmed in the quotation.
Which terms describe manufacturing and timber?
- Nordic / Northern European spruce and pine
- The approved wording for the timber in Eurodita wall logs and components. Both species are used, and a product is not reduced to spruce only or pine only unless the specific order says so. Eurodita holds no own FSC or PEFC chain-of-custody; sourcing documentation is discussed only from the actual supplier and order paperwork.
- Kiln drying and moisture target 12 to 14%
- The drying of wall timber in Nardi kilns at the Kaunas factory to a moisture target of approximately 12 to 14% before machining. The drying system runs on electricity. The target describes the timber as it leaves the kiln; it is not a performance claim for the finished building.
- Hundegger CNC machining
- The computer-controlled cutting of wall logs, joints and components on Hundegger CNC lines, working from the order drawings. The approved wording is “Hundegger CNC machining”; no machine model or count is published. Routine checks cover incoming timber, moisture, CNC accuracy, joints, joinery and pre-dispatch inspection. See about Eurodita.
- Flat-packed kit
- The form in which a Eurodita building leaves the factory: machined logs, floor and roof components, joinery and the storm brace and anchor set, packed flat for transport. Buildings are not generally pre-assembled in the factory. Assembly is by the buyer’s own crew, and unloading at the destination with suitable equipment is the buyer’s responsibility.
Which terms describe the commercial basis?
- Written quotation
- The document that fixes the scope, specification, documentation and price of an order. Eurodita quotes every order in writing and publishes no price list, so the quotation is the only price reference for a project. Prices are in EUR, excluding VAT and delivery unless stated otherwise.
- EXW, DAP and DDP
- The three Incoterms in Eurodita quotations. EXW Kaunas is the default: the goods are made available at the factory and the buyer’s forwarder collects. DAP, delivered to a named place with unloading by the buyer, is quoted per order where it suits the route. DDP, duties paid, is case by case only. See the shipping and delivery policy.
- 50/50 payment terms
- Eurodita’s default payment structure: 50% of the order value with the order or order confirmation, and the remaining 50% before dispatch from the factory. It applies unless the quotation for a specific order states otherwise. The structure is the same for catalogue, bespoke and private-label orders.
- Pilot unit
- A single first building ordered by a dealer or operator to test a product, a route or a market before a programme quantity. It is accepted practice where the order makes commercial and operational sense, and is quoted like any order. It is not a blanket “no minimum order”, which Eurodita does not offer.
- Volume-driven range vs single-project range
- The commercial shape that follows the wall profile. The 19 to 44 mm standard ranges are volume-driven and are normally discussed as a programme quantity. The 58 and 70 mm profiles, bespoke designs and glulam can be single projects. There is no single fixed minimum order; the quotation states what applies. See the dealer programme.
- Private label vs white label
- Private label is a product manufactured to one partner’s specification, so no other dealer can order the identical building. White label is a generic product several resellers sell under their own brands. In Eurodita’s private-label model the partner controls pricing and the end customer, and documentation carries the partner’s brand where agreed per order. See private label vs white label.
- Creditinfo certificate
- The Creditinfo “Strongest in Lithuania” certificate held by UAB Eurodita for 2019 to 2025, a rating of the company’s financial standing. It is the one certificate Eurodita presents about itself and says nothing about product quality, conformity or delivery. Eurodita holds no ISO 9001 certificate and makes no blanket CE or UKCA claim.
Which terms describe product families and routes?
- Catalogue model, bespoke and made-to-measure
- Three ways an order is defined. A catalogue model is a listed design with recorded dimensions, heights and a standard wall profile, as in the catalogue. Made-to-measure is a catalogue model with changed dimensions, so it has its own footprint. Bespoke starts from the buyer’s sketch or drawing; see bespoke and custom log cabins.
- Holiday-park lodge and mobile log home
- Two names for buildings in Eurodita’s mobile log home family, ordered for holiday parks, resorts and similar sites. Where a market needs a specification such as BS 3632, BS EN 1647 or the UK caravan framework, Eurodita can manufacture to that brief; classification and site acceptance stay project-specific. See mobile log homes and holiday park cabins.
- Granny annexe
- A self-contained residential building placed in the grounds of an existing home, usually for a relative. At Eurodita it is a use-case route, not a separate manufacturing system: an annexe is a residential log cabin, twin-skin cabin or glulam home specified for that use, and the planning route is the buyer’s local one. See granny annexes.
- Order drawings
- The drawings, CAD and technical data issued for a specific order with the quotation, from which the base is planned and the building is machined. They replace the catalogue figures for that order, so a made-to-measure or bespoke building is built from its drawings. The document set is agreed at quotation and can carry the partner’s brand.
- Local approval route
- The planning, architect, building-control or local-authority process a building must pass at its site. It stays with the buyer, the dealer or the local project team; Eurodita supplies drawings and technical data as input but does not obtain approvals. Installation, foundations and utilities are outside scope; see what Eurodita does not do.
- Specialist structural partner
- The external structural engineer Eurodita works with when a project requires structural calculations. Eurodita does not carry out the calculations itself; the partner works from Eurodita’s drawings, technical data and the project brief. A profile dimension on its own establishes no structural performance.
- Declaration of Performance
- A manufacturer’s document declaring a construction product’s performance for CE marking. Eurodita makes no blanket CE or UKCA claim and its IV45, IV68 and IV92 joinery is not represented as CE marked, so no blanket declaration is published. Which documentation exists for a specific product and order is confirmed at quotation.
Frequently asked questions
What is a twin skin log cabin?
A twin skin log cabin has walls made of two equal solid log skins with a cavity between them, written outer skin, cavity, inner skin. Eurodita manufactures four build-ups: 44-50-44, 44-100-44, 58-50-58 and 58-100-58 mm. The cavity is the space the insulation occupies; the insulation is bought locally and no U-value is published for any build-up.
What does EXW mean for a log cabin order?
EXW Kaunas is the default basis of every Eurodita quotation. The kit is made available at the factory in Kaunas and the buyer’s forwarder collects it; transport, export handling and unloading at the destination are on the buyer’s side. DAP can be quoted per order where it suits the route, and DDP is confirmed case by case only.
Is 44 mm the wall thickness or the log height?
It is the wall thickness. A Eurodita wall profile is written thickness first and height second, so 44 x 130 mm is a 44 mm thick wall log with a course height of 130 mm. The height is not a second wall option. The same rule applies to every solid profile, from 19 x 100 mm to 70 x 130 mm.
What is the difference between private label and white label timber buildings?
Private label is a building manufactured to one partner’s specification, so no other dealer can order the identical product. White label is a generic product that several resellers sell under their own brands. The test is whether another dealer can buy exactly what you are buying. At Eurodita, partner-branded quotations and drawings are provided where agreed per order.
Are IV45, IV68 and IV92 wall thicknesses?
No. IV45, IV68 and IV92 are the names of Eurodita’s own timber window and door systems, and IV92 is the triple-glazed route. The figures 45, 68 and 92 are joinery figures that sit next to wall profiles in a specification and get copied into the wall field. A 68 mm cabin is a cabin with IV68 joinery and a separate wall profile.
What is a pilot unit?
A pilot unit is a single first building ordered by a dealer or park operator to test a product, a route or a market before committing to a programme quantity. Eurodita accepts a pilot unit where the order makes commercial and operational sense, and quotes it in writing like any other order. It is not a blanket no minimum order policy.
Which term is missing?
This page covers the terms that recur in Eurodita enquiries and quotations. If a term in a data sheet, quotation or drawing is not defined here, or a definition does not match what you were told, send the term and the document reference and it will be checked against the manufacturing record.
