When we talk about the types of wood used to manufacture acoustic panels, we have to distinguish the two parts of a panel in which they can be used: the core and the finish.
Core: The core is the base on which the wood acoustic tiles are built and it is not visible. It is usually made of plywood or, particularly, MDF (medium density fibreboard). Actually, MDF is not exactly wood, but rather a product derived from wood, combining wood fibre with synthetic resins to achieve a higher density.
Finishes: The finish is a much thinner layer that is visible on the acoustic panel, and it is placed on the core. Finishes can be made of melamine, through-dyed MDF, HPL, lacquer or natural wood veneer. A finish in natural wood veneer allows us to enjoy the aspect of the different types of wood in existence.
Following is a review of the more common types of wood and the characteristics that define them in a general way, although some are almost imperceptible as a natural finish in acoustic tiles. There are other woods and wood finishing options that Spigogroup can include in its acoustic panels, but always as special orders.
- Beech: It offers clear, almost whitish shades, and it is very abundant thanks to sustainable forest holdings. It has a straight, fine fibre and a uniform grain. It is a heavy wood, above 710 kg/m3, and medium hard.
- Oak: next to pine, it is the most popular among all types of wood. Its colour varies from light brown to dark shades. It is resistant and relatively dense: between 700-770 kg/m3 with a humidity level of 12%. It has a straight fibre and medium grain, and offers good moisture resistance.
- Maple: It is highly appreciated for its light colour. It has straight grain, so it is easy to work. In addition, it has good resistance to deformation, torsion, shock and wear.
- Cherry: It is a very decorative reddish wood with very characteristic veining. Its fibre is straight and the grain varies from fine to very fine. It is also very easy to work.
- Birch: It ranges from light yellowish white to soft orange shades. It is a very fine wood used in woodworking. It has straight fibre and a fine grain, and has a very uniform appearance.
- Iroko: This is a tropical wood native to Africa well known for its resistance. Its grain and a colour, between yellow and brown, are highly appreciated. It is not cheap due to a shortage caused by uncontrolled farming.
- Walnut: It is one of the most highly appreciated types of wood and its price is high, as the tree grows very slowly. It ranges from light brown to dark chocolate brown and it is considered a medium heavy wood (around 650 kg/m3). It has coarse grain and a straight fibre.
- Melis pine: It is a light brown to reddish brown and quite heavy. It is a very straight fibre and medium grain, qualifying as medium hard or hard.
