What should I be aware of for exterior applications?
The panels must always be fastened to a suitable sub-structure that provides rear ventilation. A joint no less than 5mm is required between the individual panels. It is beneficial to place joint tape behind the joint. A coating is not required Sanded panels are not suitable for exterior applications.
To which sub-structures can I fasten the AMROC panel?
It is recommended to fasten the panels to a lumber sub-structure. However, the AMROC Panel can be fastened to any other sub-structure. When using various materials, their coefficients of thermal expansion and expansion characteristics under varying environmental conditions need to be observed.
Under what circumstances do I need to coat the cement-bonded particle panel, and with what materials?
In principle, the panels do not need to be coated, since they are weather and icing resistant. In most cases, coatings of any type and manner are selected for decorative purposes. The panel must always be coated on both sides, to ensure a vapor diffusion equilibrium. This is not always possible for structural engineering reasons, for instance with tiles, wood flooring, laminates or similar materials. For these applications, AMROC offers the product AMROC Color-Primed. This product version has primer applied to the front facing side and the edges, and the rear facing side has a finish coat. After the decorative surface treatment has been applied to the front facing side, the vapor diffusion equilibrium for this product is nearly intact.
What tools can I use to machine the AMROC panel?
The AMROC Panel can be easily machined with carbide tipped tools (cutting, drilling, milling). The panels can be fastened with screws, nails, staples or adhesives.
Is the cement-bonded particle panel environmentally friendly?
Our AMROC PANEL was tested for environmentally and health hazardous substances, and was classified as environmentally friendly. These tests were performed at the Institut für Baubiologie, Rosenheim (construction biological expert opinion), and also by the test lab Eurofin in Denmark (emission test AgBB), and are documented in test reports. We will provide these reports upon your request.
How can I dispose of the cement-bonded particle panel remnants.
Processing waste can be disposed of in above ground construction waste landfills.
What do I need to be aware of for when storing cement-bonded particle panels?
AMROC PANELs should always be stored flat and under dry conditions. During flat storage, the panels must be supported by wooden stretchers every 80 cm. The AMROC PANEL must always remain covered during storage and transport. The only circumstances under which a cover is not needed is if the space is enclosed and is not subject to changes in ambient humidity. (Note)
What differences exist between an AMROC panel and other construction panels (for instance cement fiber panels, gypsum fiber board, sheet-rock, particle board, or OSB)?
The differences between the cement-bonded particle panel and other construction panels are the result of its composition, the mixture ratios of wood and cement and the manufacturing process. Wood is a natural material (for instance cement fiber panels, gypsum fiber board, sheet-rock, particle board, or OSB)? Due to the wood content, the cement-bonded particle panel is lighter and more easily machined and installed, as compared to a purely mineral based construction panel, such as the cement fiber panel. The single layer distribution process (of a so-called monolithic panel) prevents delamination of the panel. This permits the use of the AMROC PANEL for applications where glue bonded construction panels can only be used with restrictions. This is the case for exterior applications, or in high humidity or wet spaces. The vapor diffusion permeability is another feature of the AMROC PANEL. This enables the panel to absorb moisture, and in contrast to gypsum bonded construction panels, is able to disperse the moisture back to the ambient air. This feature prevents moisture damage.
What fire retardant classes does the AMROC panel comply with?
The fire retardant class of construction component is designated by F30, F60, F90, etc. and depends on a variety of factors. These include the construction materials used. The construction materials are classified into various classifications and/or construction materials classes in accordance with DIN 4102, part 1, as a function of their combustion characteristics. This classification is also found in the product designation. AMROC PANEL B1 (fire retardant). However, the fire retardant classes do not provide information about the construction material characteristics in the structure. These are only influenced by the fire retardant duration (fire retardant class). DIN 4102 can be used as a reference to determine which construction materials can be used, for instance for an F90-structure (without having to conduct an elaborate and therefore expensive fire test). A simple and prompt determination can be made using table 2 from DIN 4102, part 2. DIN 4102, part 4 provides several design examples, which provide information about the layout of a structure, and also the strength and type of the construction materials that can be used for one's own design.
What fastening options exist, and what guidelines do I need to follow?
Generally, any fastening methods used on particle board is suitable. A detailed description of the individual fastening methods is provided in the product application section. (see also: fastening methods)
Can the AMROC panel be used as a plaster substrate?
The AMROC panel has only limited applicability as a plaster substrate since cracks can form at the seams. As a rule, we can only recommend dispersion plaster.
What is the difference between a floating installation and an installation on wooden beams?
In a floating installation, the entire surface of the panel is in contact with the floor. Depending on the floor, this style of installation can only be performed with glues. In many cases a bond to the floor is not desirable. In an installation on wooden beams, the panel covers a gap. The panel seams must always occur on a beam (sub-structure), must be glued, and the floor board must be screwed to the beam. The panel thickness required for each gap width is found in the material safety data sheets. [click here to download]
Can I use ceramic materials (tiles) as a surface treatment for the AMROC panel?
Ceramic materials are a suitable surface treatment for the AMROC panel. If this surface treatment is used on a floor board, it is imperative that the panel seams are glued. The floor board must then be sealed with a primer on all sides to prevent a cupping effect. Permanently elastic tile adhesives and grout must be used for these applications.
