The Comeback SWL blockboards a sustainable material

SWL blockboards – the Comeback A sustainable material for a variety of challenging applications Quality is asked again in the wood processing trade and industry – blockboard is celebrating a comeback Blockboard in focus Blockboard fell into oblivion for some time. This led to its unique properties being forgotten. Chipboard was the material of preference among carpenters, joiners and furniture makers over the years. Materials were supplied without consideration to substrate board– because customers were focused on the outer appearance without seeing the inside. This paid off, sometimes only after...

Blockboard – a carefully manufactured solid wood product Blockplywood or laminboard (according to DIN 68705-2) are also known as blockboard. As plywood they belong to the wood-based material family. The core material consists of glued collateral solid wood bars, covered on both sides by a layer of veneer. Balancing veneer Core material Referring to the width of the bars, it is differentiated between laminboard cores (STAE) made of bars up to 7mm width and blockboard cores (ST) made of bars of widths between 24 - 30mm. Balancing veneer Laminboards are thus even higher quality and are even less...

SWL Blockboard – compared Comparison of blockboard to MDF and chipboard (19 mm boards) As subject of a technical thesis for the Woodworking School Bad Wildungen, Germany, the materials MDF, chipboard and blockboard have passed several series of tests, with an obvious result. Materials in comparison: n MDF/ST E1 n Eurospan E1 P2 n SWL STAB spruce 3-layer n SWL STAE spruce 3-layer MDF Span SWL STAE Raw density in relation to weight  (in kg/m³)  (in %) 850 The raw density of a wood-based material is the relationship of mass to volume and thus representative of the weight. This parameter is the most...

A material with verifiable benefits Deflection under the influence of moisture (in mm) * After 24 hours in water, the chipboard (P2) swells to 22 mm (16 %), MDF to 23 mm (21 %) and the blockboard to only 20 mm (5 %) Even after 24 hours in water blockboard shows by far the lowest loss of stability – chipboard and MDF are virtually unusable on contact with water! Screw retention strength* Screw retention strength surface (N) 1080 900 * Brute force is needed to loosen screws. Blockboard can even be reused several times due to the excellent screw properties! Glue content* The amount of glue used...

SWL blockboard – sustainability Value and appreciation of blockboard Many consumers put emphasis on sustainable and value stable products, a tendency which manufacturers and processing companies must take into account Sustainability is increasingly important Blockboard is confirmed to have the highest level of sustainability compared to other wood-based materials. In a survey, 37.9 % of experts stated that they see the greatest benefits in blockboard with regard to sustainability. This figure was 20 % for chipboard and merely 13.8 % for MDF. This is verified by comparing the materials according...
