The structure of the board

The benefits of Rappgo´s multilayer construction

Multilayer board and solid wood board
Do you know the difference between multilayer and a solid wood board? Stability. Wood is a living material and technically hygroscopic. This means that wood strives to maintain a balance with the relative humidity in the surrounding air.

During periods of high humidity, wood swells – in low humidity, it shrinks or contracts. This natural movement can create gaps and cracks in solid wood flooring in winter.

Three-layer construction for form stability – Mörkaskog/Nordic

We have developed a three-layered construction for our wide planks to minimise cracks and give a form-stable construction. This makes cleaning and maintenance easier. By gluing three to five different layers of wood together at a 90 degree angle to each other, we have produced a stable construction where the natural movement of each different layer is minimised. The result is a dimensionally stable board with a minimum amount of gaps between the boards.

“It’s about form stability.

Sanding wooden floors

The solid wood board has a tendency to become convex so that it rises in the middle of the board, or concave so that gaps occur in the longitudinal joints. This tendency to become convex or concave is a major disadvantage when sanding the boards. Unnecessary amounts of wood have to be sanded away to achieve a flat surface. The claim that a solid wood board can be sanded more times than a multilayer board is not always true.

The multilayer board is dimensionally stable, which minimises the risk for cupping or dipping. The floorboard remains plane. The flooring can be sanded without removing unnecessary amounts of the surface. A multilayer board can therefore be sanded several times, just like a solid wood board.

New generation floorboard
A solid floorboard is 100% wood. That used to be the only type of floorboard available. The multilayer board is constructed of several layers of wood, which presents a range off technical benefits in terms of form stability.

SELECTED PROJECTS

Completed projects we like!

Reference projects are important for us – they provide an opportunity for our plank flooring to demonstrate its unique properties in beautiful environments. We hope that these environments will inspire you and awaken a passion for small-scale craftsmanship.
