Untreated wood for construction projects in Aarhus and the rest of Denmark

The choice of wood type is crucial for both function and aesthetics in a building project. For load-bearing structures, Nordic conifers such as spruce and pine are frequently used, as they have straight fibers and good strength-to-weight ratio. For visible indoor solutions or floors, professionals often choose hardwoods such as oak or ash, when high wear resistance and a dense grain structure are required.

Durability and use of untreated wood indoors and outdoors

Untreated wood lasts a long time in dry, ventilated structures where the material is not exposed to constant moisture. Indoors, it is often used in interior walls, roof structures and load-bearing columns, where the natural properties of wood provide a simple and robust structure. Outdoors, design and details must take into account drainage, ventilation and installation methods, as direct ground contact or constant moisture significantly reduces the lifespan.

Quality requirements and strength-graded wood for structures

Construction projects require documentation of strength and grading. That is why many contractors prefer wood in classes such as C18 for timber framing and timber. Strength grading ensures that dimensions and load-bearing capacity are consistent with the design calculations and facilitates inspection on the construction site. Bygma states that certification and marking typically accompany deliveries, ensuring traceability and quality assurance for larger orders.

How to choose the right untreated wood for your project

Start by assessing load requirements, installation environment, and visible finish. Then, the wood type and strength grade are selected based on these criteria. Contractors compare technical drawings with the standard dimensions and strength grades that suppliers can offer, and many professionals coordinate early with the purchasing office to avoid delays. For larger purchases, projects often choose to buy untreated wood, which is delivered in known dimensions and approved grades, simplifying logistics and ensuring compatibility with construction plans.

Practical advice for transport and storage

Avoid direct contact with moisture during transport and ensure that materials are stored elevated and ventilated on site. Proper storage minimizes warping and shrinkage and is a simple but often crucial step in ensuring that untreated wood maintains the planned dimensions and tolerances.

Interaction between workflow and material selection

Plan cutting, assembly and finishing as early as possible to optimise quantity calculations and cuts. Bygma supplies materials in standard lengths and dimensions, which allows for preparation of cuts in the workshop rather than on site, reducing both waste and workload.
