Puitkiudplaat

Puitkiudplaat is a type of wood-based fibreboard used in construction and interior applications. The term refers to boards manufactured with a cellular or foamed structure that incorporates air voids to improve thermal and acoustic performance. Puitkiudplaat is typically produced from processed wood fibres bound with a synthetic resin or pitch and formed under heat and pressure into flat panels.

Depending on the product, the board may be assembled from short wood fibres together with binders and foaming agents to create a light, porous core. Some variants include surface finishes such as paper, foil, or veneer to improve strength, moisture resistance, and ease of finishing. The boards are cut and installed like other fibreboards, and can be machined with standard tools.

Key properties include lightweight, moderate structural strength, good thermal insulation due to the cellular structure, and varying degrees of moisture resistance. When properly treated, they can have fire retardant properties and meet local building codes for insulation or interior applications. They are sensitive to sustained high humidity and water exposure, and long-term performance depends on moisture barriers and ventilation.

Uses include interior wall and ceiling panels, roof insulation, partition systems, and backing for furnishings or equipment. Sustainable variants may use recycled or certified wood fibre and low-emission binders; some products are designed for recyclability and lower environmental impact.
