Differences in the Production of Finger-Jointed Boards vs. Blockboard

Finger-jointed boards are classified as solid wood, whereas blockboard is an engineered wood product. Consequently, finger-jointed boards feature a natural wood grain, evoking a sense of connection with nature.
A piece of furniture's eco-friendliness depends primarily on its formaldehyde emission levels. When comparing an E1-grade finger-jointed board (with a formaldehyde emission limit of 0.124 mg/m³) to an E1-grade blockboard, the environmental impact is essentially the same if the emission levels are identical. However, finger-jointed boards generally use less adhesive, making it easier to control formaldehyde emissions. Blockboard consists of a core sandwiched between outer veneer layers (bonded under pressure), a process that contributes to formaldehyde emissions; finger-jointed boards lack these outer veneer layers. The two types of board can easily be distinguished by the naked eye.
