1 Siding Installation Manual for: Color Natura Rustica Wood Furring 1

2 Ventilated Siding, Principle For easy handling of the Panels use when mounting Ventilated Siding systems consist of five main components: 1 Support structure 2 Ventilated cavity 3 Thermal insulation layer 4 Siding (Color Natura Rustica - 5/16 thickness) 5 Sub mounting frame (Wood) 1 : Support Structure The exterior wall of a building is mainly made of concrete, CMU blocks, brickwork, steel or wood frame with studs and planked by gypsum panels, M4 panels, OSB or Plywood. Use a BLACK Water Restrictive Barrier (WRB) behind the Siding (no white WRB as gaps so are more visible). 2 : Ventilated Cavity The main task of the air cavity is the evacuation of moisture and excess heat. The air circulation occurs naturally thanks to the pressure difference between bottom and top. 3 : Thermal Insulation Layer The advantage of an exterior thermal insulation is to keep the entire building structure at a constant temperature and to minimize thermal bridges and thus reduce the loss of energy to a minimum. Economic as well as ecological advantages result. 2

3 4 : Siding (Color Natura Rustica) The outer skin of the building envelope has two main functions; to be aesthetically attractive as well as to protect against influences from the climate and environment. 5 : Sub frame Multi-Panels façade panels are installed on Timber/wood supports. The Multi-Panels siding concept is based on natural rear ventilation as it is the most reliable and sustainable, and provides maximum longevity to exterior Siding. Important! Siding with Multi-Panels products must always be carried out as a ventilated facade with min 1 (25 mm) distance between the Siding and the rear wind barrier lining (insulation material). In special situations (e.g. high rise buildings), local regulations may demand a larger ventilation gap, but normally 0.25% - 0.5% of the Siding area must be evenly ventilated and/or the inlet and outlet openings must have a cross section of at least 0,20 ft2/ft. Fastening of Multi-Panels Siding Multi-Panels panels are installed on Timber/wood substructures. The fastening method using visible screws allows an efficient attachment to the supporting structures (see below drawings). In fact, if using visible screws, (A4 material) screw heads are hardly visible even at a slight distance away as they fit with the overall surface and are available in the same shades of color as the panels delivered. Sub-frames strength are to be designed by a structural engineer/contractor. Thermal expansion/retraction is to be accounted for.

Screws (A4 material) Fastening with Visible Screws Heads Pre-drill all fixed and gliding point holes in panel, two fixed points per panel, rest of the holes are to be gliding points. Install panels from top of building to bottom. For straight walls, start panel installation in center and work outward. For walls with inside corners, start installation there and work across wall. Screws must be located in the center of each hole in the panel. They must be perpendicular to panel surface, and not be over tightened, which would prevent the panel's normal thermal movement and can create cracks in the panel s.

6 Fixed and Gliding Points Diameter of the fixed hole (F), use #8 drill bit (5.05 mm) (Fig 8-9) Diameter of the gliding (G) use #O drill bit (8.02 mm) (Fig 8-9) Two fixed points are required per panel are always the same height in each panel, close to center of panel as possible, and then either the next adjacent point to the left or right. Be consistent in panel-to-panel location (center and left or center and right, so fixed points are at the same level horizontally for attachment to vertical profiles). Two fixed points (F) on one panel can not be on the same profile, and no two fixed points (F) on two adjacent panels can be on the same profile- For smaller panel sizes with only two rows of fasteners, fixed points (F) to be top center and top left or top right (horizontal applications on vertical profiles). For vertical narrow panel applications on vertical profiles, vertical joints must incorporate two separate profiles. Fig-8 Fig-9 6

7 Panels cannot bridge a break in the wood furring. Fig-10 Fig-11 The installer is responsible for establishing a plane and strong sub-construction able to obtain the wind loads appearing on the actual facade and observing the fixing distances. Facade panels are normally installed in a vertical position on a vertical sub-structure. However, it is also possible to install the panels in a horizontal position. The guidelines for fixing are the same. Thermal expansion/retraction is to be accounted for. 7

8 Fig-12: Screw distance to Edges (Screw heads are normally same color as the Siding Panel) Corner fasteners to be located at a minimum 1 and maximum 3.93 horizontally and a minimum of 2.75 and maximum 3.93 down/ up vertically from each corner of panel. Space between panels minimum 5/16 Processing and Storing CUTTING All Multi-Panels panels may be cut with a circular saw or a jigsaw equipped with a diamond tipped blade. Sharp edges are made with fast running diamond tipped tools. Cutting to size may be done with normal slow or fast running hand tools or stationary equipment. When using fast running tools, dust exhaustion must be employed. Note: When using hand tools, cut the panels backside up. When using stationary saw equipment, cut the panels front-side up (the saw blade must always attack the board from the front-side). The periphery speed of the circular saw should be as depicted in the below table. Cutting depth should be 3/8 5/8 (10-15 mm) beyond the board. 8

It is recommended to drill a min 7/16 (8 mm) hole before cutting in the inside corner. In order to avoid creating a notch at the inside corner, cut edges should be sanded. CLEANING OF PANELS AFTER CUTTING AND DRILLING It is important to immediately remove dust caused by cutting and drilling from the front and backside of the panels with a soft brush/duster or a vacuum cleaner as it might damage the panel surface. Ensure that the panels are properly cleaned before installation, and if necessary use clean water or water with a mild detergent and a soft sponge or brush to remove dirt and dust from the surface. Thereafter, wipe the panels with a damp cloth. It may also be necessary to wash the surface after installation if the building site conditions have been unfavorable. This is done with clean water or water with a mild detergent and a soft sponge or brush and finally wiping the panels with a damp cloth. 9

10 PROTECTIVE FILM Multi-Panels painted panels (Color and Natura) are equipped with polyethylene film between the panels for protection of the surface during transport and processing, the polyethylene film must be immediately removed after installation. (otherwise it can destroy the panels) SAFETY As with all other building materials, safety precautions must be taken into account and local laws and regulations must be observed. Cutting and drilling are subject to dust development, and proper precautions must be taken by using appropriate dust extraction equipment. Dust from fiber cement panels is characterized as mineral dust and prolonged exposure to this may cause lung disease. Fast running electrical equipment such as hand held circular saws leave a fine and sharp edge on the panels and provide fine dust. Due to the speed of the blade the dust is dispersed over a larger area. Therefore, it is necessary to establish sufficient exhaustion and it is recommended the operator carry personal safety equipment. APPLICATION CONDITIONS Board temperature and ambient temperature should be + 44 F (+7 C) - 86 F (+30 C) and relative humidity <85 % (optimally 60 %). Process temperature must be min +44 F (+7 C). APPLICATION - FINISHING THE EDGES TO CUT WITH HYDRO BLOCK EDGE SEALER Note: These Instructions are mandatory for Color, Natura and Rustica siding panels. Before use, shake the Hydro Block thoroughly. In case of unventilated premises, use required protective respiratory equipment, wear protective clothing, safety goggles and gloves according to the Safety Datasheet. Carefully apply the solvent-based Hydro Block in a thin layer with a short hair roller. Excess Hydro Block on top of the surface should be removed immediately after painting. Disposal of this product must be with reference to local and national regulations. STORING, PROPER HANDLING & FORKLIFT Multi-Panels products are delivered with plastic protection cover on the pallet. If undamaged, the plastic cover protects against weather conditions during transportation. The plastic cover is for dust protection only and should be removed upon arrival at the building site. Hereafter the pallets should be kept under a roof, leaving the possibility of ventilation around the panels. Multi-Panels must be stored on a flat and dry level surface on pallets or sleepers with a minimum distance of 12 between the stacks on all sides. Note: Max. 5 pallets in a stack at the warehouse and on the building site max. 2 pallets in a stack. Proper handling: The panel must be lifted up vertical and off the pallet by two persons and NOT horizontal and off the pallet, as this can result in cracks in the panel, outside the scope of the Warranty, also do not drawn panel over the next panel, as this will cause scratches and damage on the surface. Forklift: Fork length must support pallet entirely; if required, use fork extensions. 10

11 General Information ANNUAL INSPECTION Normally, a Multi-Panels facade does not require maintenance to maintain its strength, properties and function, but an annual inspection of the surface, ventilation gaps, joints and fixings is recommended. Environmental impacts may, however, influence the visual appearance of the façade. Detection and repair of possible damages help promote a prolonged lifetime for the facade. HIGH PRESSURE CLEANING Warning High Pressure Cleaning is a rough treatment of a fiber cement siding. Use of a high pressure cleaner may damage the surface. Therefore, high pressure cleaning is not recommended. CLEANING OF DIRT Never clean a facade in bright sunlight, the Multi-Panels facade panels can be cleaned with cold or hot water with the addition of a mild household detergent not containing solvents. Before full scale cleaning it is recommended to test the selected cleaning method on a smaller area to make sure it performs as expected. Rinse with plenty of clean water until the facade is perfectly clean. MOSS AND ALGAE REMOVAL Never clean a facade in bright sunlight. Moss and algae growth can be removed with common detergents available on the market, examples are: Chlorine or Rodalon 2.5% active that has a long-term effect of preventing new growth. After wetting the Multi-panels with clean water, apply detergents according to the supplier s instructions. Do not leave the detergents to dry completely and be sure to rinse with plenty of clean water to remove the moss and algae. IMPACT BY POLLUTION AND NATURE Weather and nearby vegetation may affect the appearance of the panels. Take caution to avoid pollution, dust and leaves from trees, bushes and flowers to not impact the integrity of the panels.
