Cement bonded particle board: AMROC-Floorboards - Product description

The Amroc-Panel stands up to the highest expectations when used as drywall, and features superior walking comfort, compressive strength and acoustic insulating characteristics. The "one man" panel in a 1,250 x 625mm size has proven its use. It has a sanded surfaces on both sides, and features a tongue and groove edge profile on all sides.

The panel can be used in floating installations, requiring the panels to be glue-bonded at the profiled edges at all times. A felt substrate layer (or similar) is used as a footfall sound insulator and increases walking comfort. Furthermore, a vapor diffusion barrier must be installed under the floorboard. As an additional installation option, the panels can be mounted to floor beams for modernization work on old structures. For this application, the panels are also bonded to each other with glue and are additionally mounted to the sub-structure with screws. An important consideration is that seams should not be freely floating between beams. On floor beam installations, the required panel thickness is determined as a function of the foot traffic and the support centers,in consideration of the required safety parameters

Depending on the floor space and shape, allowances should be made for expansion joints based on flooring installation guidelines. It is common practice that several weeks can pass between the installation of the panels and the application of the surface treatment. This results in inconsistent drying of the panels, causing "cupping" (arching of the panel) As a countermeasure, the flooring must be covered with plastic sheet until the surface treatment is applied. Using panels that are factory primed on both sides (grey/grey) eliminates this problem.

We therefore recommend the use of the factory primed panels Amroc-Color Primed. The required installation quality can only be achieved by taking this step, especially with respect to a subsequent surface treatment with ceramic or similar materials.
