Material types - Slat boards

416 Slat boards are usually constructed as a three-layer construction. At the bottom a bottom layer of coniferous wood with the fibers in the longitudinal direction of the board. A middle layer or barrier layer of eg. particle board, plywood, MDF or cross-laminated hardwood or softwood slats. Top a wear layer that is at least 2 mm thick, but which in most lamella boards usually has a thickness of 3-4 mm. The wear layer can be made of one piece of veneer or divided as the stake park. Slat boards are therefore available with the appearance of floorboards, parquet or pattern park.

Slat boards are provided with ferrules and grooves on all four sides and are also available with a locking ferry and groove system (click system), which eliminates the use of glue in ferries and grooves for swimming floors.

Slat boards can also be laid as glued or nailed floor, or as bearing floor, if the slab thickness is at least 22 mm.

Types of materials - Stake parquet

412 The stake parquet is single rods, usually in solid wood. The rods are rectangular with ferries and grooves. The solid rod park is also found without ferries and grooves.

The stake park is made from the traditional European tree species such as beech, oak and ash, as well as from a number of overseas tree species, eg padouk, merbau, doussie, jatoba and wengé.

The rods are usually 200-700 mm long and 50-70 mm wide. The thickness is usually 15-22 mm. For rods without ferrules and grooves, the length must not exceed 300 mm, and the thickness can be down to 10 mm. Parquet staves are also made as so-called long bars, which have a length of 700-1200 mm.

Parquet floors are laid either as glued or nailed floor. Longer bars, which are at least 20 mm thick, can also be laid as a bearing floor.

Types of materials - Parquet boards

413 Parquet boards are solid single rods that are assembled at the factory for boards. Usually two parallel rows of rods are used, which are assembled with a special dovetail collection. The boards are provided with ferries and grooves on all four sides, and are available in lengths as ordinary floorboards.

Parquet boards can be laid in the same way as ordinary floorboards, ie. as a bearing floor when the board thickness is at least 20 mm, or as a nailed floor.

Parquet boards can also be used for floating floors, which are assembled with hangers or clips (gluing of the boards is usually not suitable for parquet boards).

Types of materials - Floorboards


Floor boards are solid boards made of pine, spruce, douglas etc. Hardwood, eg oak and merbau, are only used to a lesser extent. Floorboards are planed and plowed boards, usually found in widths from 75 to 180 mm and in thicknesses from 14 to 30 mm. Standard products can be ordered up to 40 mm in thickness and 450 mm in width. The length is usually between 1.8 and 5.4 m. If delivered in decreasing lengths, some of the boards in a delivery can be shorter. Delivered in fixed lengths, part of the lot, often 5-10%, will be delivered in shorter lengths for the utilization of the raw material.

Flooring floors are sometimes referred to as plank floors, although none of the products have sufficient thickness (planed, directed at least 42 mm) to be referred to as planks. The boards only have a plank-like appearance.

Boards that are at least 20 mm thick can be laid on beams or joists as a load-bearing floor. The support distance must be matched to the thickness and load, see Tables 2 and 3. For smaller board thicknesses, full support of the floor surface is required.
