Thickness +/- 0,5mm, width +/- 0,5mm, length +/- 1mm, inequality of upper surface no more than 0,5mm.
7 +/- 2%
Wood color in different packages and deliveries may vary. For more information slick sorting types.
High hardness, high resistance on biological destruction, acoustic isolator, natural regulator of air humidity. Product doesn’t cause allergy.
It might be necessary to adjust the ground in order to achieve the right parameters. The ground and the room might also need seasoning (process of removing moisture content) in order to achieve the right hygroscopic balance between the wood and the surrounding. Optimal humidity the wood has to achieve to be ready for installation is 7% +/- 2% with the air humidity at 45-55% and cement substrate humidity up to 2% (anhydrite up to 0,5%).
Substrate inequality can be max. Of 2mm on a 2 linear metre distance in every direction.
