The structure of our wooden floors
Wood is a natural material, which means it responds to changes in the surrounding humidity. When humidity is high, the wood expands; when it’s low, it contracts. This movement can cause floorboards to warp, creating gaps between the boards or causing them to lift in the centre. To minimise these issues, careful consideration must be given to the type of wood floor, its installation, and the conditions where it will be installed. These problems are more pronounced with longer, wider planks, especially when installed over concrete or with underfloor heating.
Three-layer cross-glued plank floors
For enhanced stability and a maintained feel.
At Kullaberg Flooring, quality and customer satisfaction are our top priorities. To meet the needs of our customers, we’ve developed an extra-wide and long solid wood floor designed for those who may not have the ideal surface for traditional options—a concern for many of our clients. These plank floors consist of three layers of wood, cross-glued to reduce movement to just one-tenth of that found in classic solid wood floors.
The cross-glued design provides the same aesthetic as a traditional solid wood floor, but with significantly improved shape stability. This offers greater peace of mind for customers who desire the character of solid wood without worrying about long-term quality issues. As far as we know, we are the only company on the market offering floors of this length and width with such enhanced stability.
Floor installation instructions
A plank floor from Kullaberg Flooring is easy to install, using the same method as most other solid wood floors from other manufacturers. Sanding and surface treatment are not required after installation, as these steps are already completed during manufacturing, unless specified otherwise by the customer. However, depending on the chosen surface treatment, a final polishing may be needed once the floor is installed.
For larger or more complex projects, we offer installation and surface treatment services. We can also assist by guiding local craftsmen to ensure a smooth process.

Floor heating
Our solid wood floors can be installed over floor heating, but there are a few important considerations to keep in mind, as wood responds to temperature changes. Below are some tips for installing wood floors with floor heating:
- Ensure that the concrete slab beneath the floor has a moisture content of 80% RH in the centre.
- Wood floors are best suited for environments with a relative humidity between 30% and 60%.
- Floor heating can dry out the wood, causing it to shrink more. To minimise this shrinkage, we recommend our three-layer cross-glued wood floors.
- Use a moisture barrier to protect the wood from moisture rising from the foundation.
- For newly built homes, it’s a good idea to use temporary heaters to accelerate the drying process of the concrete foundation. Without this, it may take up to a year for the concrete to reach the appropriate moisture level, potentially delaying the installation of your floor.
- Always follow the manufacturer’s instructions when starting up your floor heating system.

Care and maintanance
Aging with patina.
Proper care is essential to preserving the beauty of your plank floor for as long as possible. The type of surface treatment you choose will determine the level and type of maintenance required. We recommend hard wax oil as the surface treatment for its excellent protection, ease of maintenance, and ability to retain the natural character of the wood.

Cleaning and maintaining your oiled wood floor
A solid wood floor is best maintained with dry cleaning methods, such as sweeping or vacuuming. When necessary, it can be mopped using a well-wrung cloth or mop. Be cautious not to use too much water, and be mindful of your choice of cleaning products. Standard natural soap has a low pH, which does not help to rehydrate the wood.
For optimal care, an oiled wood floor should be cleaned with a re-greasing soap that has a pH of around 8-9, ideally with a grease content of 20-30%. This will keep the floor both clean and rehydrated.
For plank floors treated with hard wax oil, we recommend applying maintenance oil every five years, especially on high-traffic areas like kitchen walkways.
