The side-lock solid wood flooring is a glue-free, keel-free, flat push floor that can be installed easily and cost-efficiently. Its remarkable advantages are that the PPR plastic lock saves wood and increases the surface utilisation rate by more than 10 per cent, that it is easy to install and that it can be reused. The floor is resistant to high temperatures, waterproof as well as resistant to deformation and ageing, which ensures a long and healthy service life thanks to environmentally friendly materials and processing. This system is known as a recognised DIY solid wood flooring.
