Birch plywood structure – unparalleled stability
The cross-glued three-layer structure significantly reduces the hygroscopic changes of the parquet board and its reacting to fluctuations in air humidity and temperature, compared to solid plank or 2-layer wood flooring. Possible hygroscopic changes take place inside the structure, and the floor therefore rarely gets cracks, which usually happens with solid wood floors.
Plywood products are normally considered to be 2-layer structures, but they do not have a counter balance veneer like in the Timberwise products. A counter balance veneer adds a 3rd layer to the product, which makes floating installation possible for the product and it stays stable.
As a forerunner in the industry, Timberwise uses a 9 mm thick Finnish hardwood birch plywood panel as the middle layer structure, which is considerably more durable and stable than the generally used softwood plywood.
The hygroscopic changes in the structure are reduced, because the so-called mirroring effect which is typical to a strip middle layer does not exist in the case of a birch plywood middle layer. The surface of the floor remains even and no wave effect occurs. The product is suitable for challenging conditions occurring for example in Scandinavia, Southern Europe and the Middle East, where temperatures and humidity vary depending on the season.
The mechanical durability of the floor also improves: the floor is more sturdy and durable. Furthermore, the birch plywood structure provides the floor with more efficient sound and damp-proofing.
WiseLoc – easy to install locking tongue and groove
The WiseLoc locking tongue and groove is easy and fast to install. The floorboards can be installed one by one, because the 5G end tongue will lock into the previous floorboard with the help of the spring. Therefore, it is not necessary, for example, to install the floor one row at a time at a certain angle, which requires several installers, but one floorboard at a time. A locking tongue and groove is faster to install than a glued tongue and groove parquet, and if a problem that needs to be fixed occurs during installation, dismantling the floor is quick and easy.
The WiseLoc lock system floor requires a very even subfloor, because the allowed deviation is only ±2 mm / 2 m. If there is a higher deviation in the floor, it must be levelled before installation.
More information about the installation of the locking tongue and groove system is in the installation instructions.
