There are many arguments for wooden constructions. For example, the environmental benefits associated to building with wood. Trees take CO2 out of the atmosphere and store it both in forests and in the structures of wooden buildings in cities. Carbon dioxide stays stored in wood, even when it is transformed into wood-based products. Another reason, according to a research quoted from the architecture website Archdaily.com; “the life-cycle emissions of wood houses are 74% lower than those of steel houses and 69% lower than those of concrete houses”.
Thus, new wood-based materials coming into the market means more options for architects and builders when conceiving and planning wooden buildings. This is always good news, especially if they are poplar based.
That is the case of Lignumstrand, the new wood-based building material made of PEFC certified local (Spain) poplar wood, available for the construction market.
On July 3rd, the EAD permitted the CE marking for Lignumstrand and it was published on the EU Bulletin, allowing it to be commercialized throughout the European Economic Area. Made by the Spanish company TABSAL, Lignumstrand is a product of the LSL family (Laminated Strand Lumber), quite a common product in mature wood construction markets such as North America, Canada, or the United Kingdom.
The Lignumstrand E 10700 offers extraordinary stability and resistance, as well as good behaviour against fire, at the level of the best of woods. Structural Lignumstrand is presented as a unique product from the environmental point of view due to its composition.
It gets the highest score, A + in the French evaluation system, as due to its raw material and process its carbon footprint is minimal.
It is a very versatile material and can be directly used as a beam or as a component of composite beams, whether they are double T, box, lattice, or others, or as posts, lintels, uprights, straps, braces, boards and other structural elements of construction.
