3-layer or 2-layer parquet: which is the best choice for you?
The 3-layer structure of Lignum Venetia is the highest expression of pre-finished parquet. This structure takes its name from the number of layers that compose it: the first layer formed by a folder of noble wood of variable requested thickness, an intermediate layer composed of a central core consisting of strips of spruce fir and a last layer, also called against plack, made in essence or in finger joint ash. The standard thickness of 3-layer boards is 16mm but upon request they can be made with any other thickness.
This particular construction and above all the use of rigatino fir as a central support ensure the floor an extraordinary stability and durability over time allowing both floating type installation (without the use of glue under each individual bridge) or glued installation, even on underfloor heating systems.
In the central part, a particular asymmetric milling operation is carried out on both sides and this guarantees considerable durability and stability over time and throughout changes in environmental conditions.
The advantage of the floating installation is that, having no glue underneath each table, if you need to inspect the area under the floor (such as in the case of underfloor heating systems), it’s possible to remove the planks without ruining them.
With a 3-layer Lignum Venetia parquet it is possible to obtain boards with large dimensions thanks to the third layer acting as a counter-plate, the forces present inside the wood are balanced.
The 2-layer structure of Lignum Venetia is a board composed of a layer of noble folder glued with D4 vinyl adhesive onto a support in phenolic birch plywood, resistant to moisture and water.
Unlike the 3 layers, this type of board does not have the counter-plate layer at the bottom and for this reason we always recommend installation with glue in order to guarantee the right stability over time.
The 2-layer wooden floors are smaller in size than the 3-layer ones and have a reduced thickness, ideal for renovations. It often happens that we are faced with situations where, in order to renovate, for example, one's own home, one chooses to glue the parquet on an existing floor to avoid its complete dismantling. If, for some design reason, problems with the thickness are found, the ideal solution is to lay wooden boards with a 2-layer structure that can reach a minimum thickness of 9mm.
