SILBONIT Hydro/HydroPlus Standard
SILBONIT are asbestos free double pressed and autoclaved flat boards. They are reinforced with mineralized cellulose fibres and through coloured, with smoothed surface and rectified edges. Silbonit boards are CE marked according to EN 12467. Their excellent mechanical properties make them one of the most suitable finishing materials for reliable and elegant, high-quality solutions.
Silbonit cladding boards are specially designed for external cladding, semi exposed and external lining applications. Applied on a ventilated façade, Silbonit fiber cement products are strong, durable and lightweight, which provides an attractive cost-effective solution for a wide variety of projects. Can also be used for internal design solutions.
Through coloured range is available in Hydro or HydroPlus treatments.
Product colors
13 different through coloured shades and a smoothed surface give Silbonit Hydro and Hydroplus finishing boards an extremely natural appearance, which is their main feature.
Non uniform colours and some small imperfections of the surface are a feature of the product.
Colours, even through reproduced with great care, can vary compared to the original ones. For colour choice, one must decide from samples, keeping in mind that some difference in tone is possible between different batches and that every board is unique.

Application
Silbonit boards can be used for various purposes, but their basic application is in ventilated facades and interior decoration.
External cladding, semi-exposed & external lining applications.
Installation
Silbonit façade boards must be installed on vertical timber battens or vertical metallic profiles, with a maximum spacing of 60 cm between fixings. 8 mm thick boards are admitted for installation with visible mechanical fixing. For concealed fixing, thicker boards must be used.
An adhesive gasket must be placed between the sheets and the vertical profiles of the subframe, which must not be longer than 3 meters. The number of fixings per square meter is according to the size of the sheets, the distance of the subframe from the wall and the conditions of use. The fixings must be aligned both vertically and horizontally. The boards should be pre-drilled. The corner holes must not be equidistant from the longitudinal and transverse edge. No percussion tools should be used to drill the holes. The diameter of the hole should be larger than the diameter of the screw or rivet (except for the fixed point). Countersunk screws should not be used. A gap of at least 8 mm is necessary between the sheets, both lengthwise and widthwise. Use circular saws with diamond blades to cut on site; the cut is to be made dry.
Warning. The above information is purely indicative, although it is based on our many years of experience. It is the customer's responsibility to ensure that the product is suitable for the intended use and to accept any liability arising from its use.
Transportation & storage
Individual pallets must be transported. Transport must only be carried out with covered vehicles.
The panel packages must be stored in well-ventilated, indoor, and dry rooms, protected from atmospheric agents and sunlight. The panels must be stored with their own pallet, which must lie on a flat, dry surface. For prolonged storage, at least a part of the protective plastic should be removed from the packages. The panels must never come into direct contact with the ground. Do not stack more than two pallets.
