Key terms to show off your fancy board
Core
This is the base of the board, which is made of wood or synthetic foam material. Boards with a wooden core are considered to be stronger, more stable and more responsive to movement.
Coniferous and deciduous woods, as well as combinations thereof, are used in production.
Boards with a foam core are not as responsive, but they are lighter and less expensive.
Construction
The sandwich is a core with double-sided glass fibre braiding. It performs a protective function and also increases the rigidity and elasticity of the snowboard. A cover is glued on top, and the side walls of the ‘sandwich’ are covered with a separate strip of ABS plastic. This construction is considered to be the most resistant to stress.
In snowboards with a cap construction, the core is covered with a cap that folds over the edges of the snowboard to the very edge. As a result, the sidewalls are not a separate piece of plastic, but a continuation of the top. This solution reduces the weight and cost of the snowboard. However, it can delaminate under excessive loads, which complicates its repair.

The hybrid construction is a combination of the first two options. Here, the central part can be made in a sandwich type, and the nose and tail in a cap type.
Reinforcement
To reinforce the wooden core, belts or strings made of fibreglass, carbon fibre or Kevlar are used.
Braiding
Special fibres or threads protect the core and give it additional flexibility. Such braiding is made of carbon fibre, fibreglass or Kevlar. Its type is determined by the method of applying the threads.
Sliding surface, or base
The base is the bottom surface of the snowboard, on which it slides on the snow.
Extruded bases are made of polyethylene. They are rolled between rollers and glued to the board. The advantages are inexpensive production and ease of use.
In the production of a sintered base, polyethylene droplets are baked under pressure to obtain a porous material. It perfectly absorbs and retains the wax used for processing. This makes it possible to obtain a perfectly smooth surface and, as a result, achieve high speed when riding.
The most advanced type of base is the sintered version with graphite. It has a more porous structure and therefore retains more wax. However, there are some drawbacks: this surface requires regular treatment and is more susceptible to damage.
Snowboard shape
There are three types of shapes:
- twin-tip (symmetrical);
- directional-twin (directional symmetrical, or universal);
- directional (directional).
