According to standard PN-EN316 fibreboard is a material produced from lignocellulosic fibers with the use of heat and pressure. Fiber bindings can be achieved as a result of full and natural adhesion propertiesof the fibres or further by the addition of a binder ( glue) . Fibreboards have a single layered structure, it means they are formed of one sized particles. In contrast to the MDF boards, other fibreboards (i.e. so called hard boards) are formed using the "wet procedure" (fibers obtained in this process contain more than 20% of moisture). Hard boards formed using the wet method imprint characteristics of the net on one side.
Methods of refining:
Hard boards: covering material with painting and varnishing, plastering other
materials (eg. decorative foils)
Porous plates: Bituminization
Hard boards (HB) ≥ 900 kg / m 3,
Semi-hard boards (MB) 400 and 900 kg / m3.
Porous boards (SB) 230 kg / m3 ÷ 400 kg / m3
Types of fibreboard (wet method)
Among hardboard panels we distinguish general purpose boards (type HB) used in dry conditions, the type HB.H used in humid conditions, the type HB.E used in outdoor conditions. Load bearnig boards are divided into panels used in dry conditions (type HB.LA), plates used in humid conditions (type HB.HLA1) and plates with increased load-carrying capacity in use in humid conditions (type HB.HLA2).
Semi-hard boards consist of general purpose panels (type MBL and MBH) used in dry conditions, type MBL.H and MBH.H used in humid conditions, the type MBL.E and MBH.E used in outdoor conditions. Semi-hard load bearing plates are divided into panels used in dry conditions (type MBH.LA1) plates with high load-carrying capacity used in dry conditions (type MBH.LA2), load bearing panels used in humid conditions (type MBH.HLS1) and plates with increased load-carrying capacity used in humid conditions (type MBH.HLS2).
There have also been distinguished following types of porous boards: general purpose boards (type SB) used in dry conditions, the type SB.H used in humid conditions, the type SB.E used in outdoor conditions. Load Bearing plates were divided into panels used in dry conditions (type SB.LS) and plates used in humid conditions (type SB.HLS).
In addition, some manufacturers have on offer boards with increased parameters of the reaction to fire,plates with tight spaces with shaped design connectors on the tongue and groove and perforated plates or bituminized.
