WALL PANELLING WALL PANELING Panelling is a wall covering constructed from rigid or semi-rigid components. These are traditionally interlocking wood, but could be plastic or other materials. INSTALLATION OF PANELLING PREPARE THE WALLS : Paneling may be installed on three different types of walls (Fig. 1). Panels less than 1/4“ thick need a solid backing. Panels 1/4" and thicker can be installed directly over even framing members– studs or furring strips. All paneling may be put up with nails or with a combination of panel adhesive and nails. INSTALLING ON A MASONRY WALL: First check the masonry walls for excessive moisture. Walls with moisture must be completely waterproofed before they are paneled. Moisture can sometimes be caused by condensation. If this is the case, add a waterproof vapor barrier over the wall. INSTALLING WITH ADHESIVE: To hold the panels firmly to the wall, apply 3" long 1/8" beads of a solvent-based panel adhesive to the studs or solid-backed wall. At the panel edges, apply a continuous zigzag bead. If the wall has been papered, the wallpaper must be removed before applying adhesive. Place the panel in position on the adhesive and drive several nails loosely in the proper position. Then pull the panel about 10" from the wall at the bottom, resting it on a block of wood. The adhesive will become tacky in 2 to 10 minutes. Heavy panels need additional support, with nails 16 to 20 inches apart. In this case, you need not pull the panel away from the wall to allow the adhesive to become tacky. PLYWOOD USED OVER PANELLING Plywood is probably the most widely available manufactured board material. It is made by bonding together a number of thin veneers of softwood or hardwood - or a combination of each.The more veneers used, the stronger the plywood. Both the type of glue and veneers determine the suitability of a sheet for a particular application. The finish quality of plywood varies enormously. Exterior grade plywood (WBP - Weather and Boil Proof) is specially made using a water-resistant adhesive to withstand a certain amount of moisture and can be used for outdoor constructions - sheds etc. Internal plywood is of a similar quality as Exterior grade but it does not use water resistant adhesive. It can be used for wall panelling, flooring and furniture. Shuttering Ply is used in the construction industry for making shuttering boxes for containing concrete while it goes off. SIZE OF PLYWOOD Plywood is normally available in 2440 x 1220 sheets (or subdivisions) and in thicknesses from 3 to 35 mm. Working with plywood- If the sheets are to be used in a centrally heated room, store them in similar conditions before use so that the moisture content of the sheets will stabilise before installation - this will avoid shrinkage later. Cutting- To avoid damage to the finishing face, cut into the panel from that face - for hand sawing have the face upwards, for power sawing have the face downwards. To reduce the damage, score through the outer veneer on both sides of the sheet using a sharp knife before starting to saw. Thin sheets (up to 3mm) can be cut using a sharp knife. From 3 to 6mm use a tenon saw. From 6 to 12mm thick, use a fine tooth panel saw. For thicker sheets use a coarse tooth panel saw. Fixing- Plywood may be fixed in place with adhesive and screws or nails. Where a corner joint is required, fit a softwood batten in the corner so than both sheets of ply can be fixed to it. For thin material, always fix plywood to a pre-made frame, use glue and panel pins (on about a 200mm pitch), use a punch to knock the head of the pins below the surface. The frame should support all edges of each plywood sheet and at about 400mm centres (for 6mm ply), 600mm centres (for 9mm) or 900mm centres for thicker material. Finishes- Plywood which is supplied with a decorative veneer can be varnished or painted but to get a really smooth surface will need good preparation as most plywoods are not as smooth as planed timber. Sheets are also available with pre-printed faces such as mock panelling. TYPES OF WALL PANELLING Wall paneling is an architectural element that can be installed in residential or commercial buildings. Decorative wall paneling is installed over walls to add aesthetic appeal, while other types of paneling may be added for their functional or structural characteristics. Decorative Wall Panels Decorative wall panels are available in many different materials. They are often used to change the look of the wall, but may also be installed to help protect the wall from damage. Wainscoting is one of the most commonly used wall panels. It is made from wood or synthetic materials patterned with carvings and designs. Wainscot is usually installed on the lower half of a wall, but heights and styles may vary. TILEBOARD Tileboard panels are made from melamine or resin and are used to mimic the look of ceramic tiles. They are textured and colored to look like tile and are attached to a moisture-resistant backerboard. These panels are an affordable alternative to ceramic and are much easier to install. UTILITY PANELING Utility paneling is made from perforated hardboard and is used for its function and appearance. These panels contain rows of small holes that can be used to hang objects from nails or pegs. They are frequently used in kitchens or garages, as well as in commercial applications. Utility paneling is available in standard white or natural wood finishes and also in custom colors. These panels can be installed over the entire wall or just in small areas as needed. ACOUSTICAL PANELS Acoustical panels are used to control noise levels in a space and to block noise transfer through walls. They are made from foam or wood cores wrapped with a layer of vinyl or fabric.The panels help absorb sound and are commonly used n schools, auditoriums and hotels. These panels are available in a wide variety of colors and textures to match the room's decor. Acoustical panels can be installed temporarily using clips or magnets, or with nails or adhesive for more permanent applications. STRUCTURAL WALL PANELS Most types of wall paneling are installed on the interior, others are used to create exterior walls. These panels are frequently made from precast concrete and allow for quick and easy framing of homes and businesses. Structural insulated panels (SIPs) take the place of wall framing, interior drywall and exterior sheathing or siding. They are made from sheets of rigid foam insulation sandwiched between layers of wood fiber board. WAINSCOT PANELING Wainscot or wainscoting is a paneling style applied to the lower 3' (900mm) to 5' (1500mm) of an interior wall, below the dado rail or chair rail and above the baseboard or skirting board. It is traditionally constructed from tongue-and-groove boards, though beadboard or decorative panels are also common. USE OF PANELING Panelling was developed in antiquity to make rooms in stone buildings more comfortable. The panels served to insulate the room from the cold stone. In more modern buildings, such panelling is often installed for decorative purposes. Wall panels serve many functions, from providing descriptions of exhibits in museums and galleries to hiding away electronics such as stereo speakers. It is also used for decorative purposes. Modular wall panels may be constructed of wood or metal and are often covered with textured materials, fabrics, panelling or wallpaper to make them more aesthetically pleasing. In the business setting, there are portable or temporary wall panels that can be used to divide a space into cubicles. There are also acoustical and sound absorbing wall panels that are perfect for the studio. Wall panels are convenient and practical whether used for functional purposes or simply as an aesthetic element. APPLICATIONS Paneling may be applied to drywall, directly to wall studs, or to furring strips applied over masonry surfaces. Many homes have wood paneling that covers all or part of a wall in a living room, study, family room, or similar space. Paneling is paired with another material on a single wall--it isn't unusual for the top of a wall to be drywall and the bottom half to be wood paneling or wainscoting, for example:Wood paneling is typically installed as solid, interlocking boards. Sheets of wood are fairly thin, normally 1/4 to 3/4 inch thick, and are made of different kinds of hardwood that can be given a clear finish or less expensive woods meant to be stained or painted. Boards may be milled to overlap or to interlock with tongue- and-groove or shiplap edges. Wood paneling is also sold as a 4-by-8-foot sheet material with a wood-veneered or simulated wood surface. FINISHING OF DIFFERENT TYPES OF PANELLING Cut your wood or plastic moldings in a miter box using a fine- tooth saw. If the moldings are prefinished, clean them with a dry cloth. Otherwise, apply paint or stain and a clear finish to complete your paneling project. Paneling can be cleaned with a dish detergent solution or mild cleaner. Avoid strong alkalis and solvents. Exercise care if the shellac or varnish is cracked, as moisture may penetrate and stain the grain. Beware of cleaning bare wood. Since unsealed wood lacks a shield of finish, the grain will absorb moisture, grease, crayon and fingerprints. An unfinished panel is hard to clean without making it look worse and requires regular "feeding" with oils and polishes to prevent wood drying. o MAINTENANCE External coating systems must be maintained in accordance with the respective manufacturer’s instructions and all damage repaired promptly to ensure the ongoing weather tight properties of the coating systems. In addition to these system-specific requirements, the following general maintenance procedures must also be implemented Any dirt accumulation or organic growth that may occur should be regularly removed from the external surface by cleaning with warm water and detergent and a soft bristled broom. Solvent-based cleaners must not be used. INSTRUCTIONS FOR CLEANING Step 1- Dust wood walls and paneling with a soft rag, or vacuum with a vacuum cleaner brush about every two weeks. Step 2- Use a soft cloth to apply oil soap to particularly dirty wood according to the oil soap manufacturer's directions. Step 3- For tough stains, clean the wood with mineral spirits as a last resort. To test for staining, use a soft cloth to apply the spirits to an inconspicuous area of the wall. If the spirits do not stain, moisten the cloth with mineral spirits and lightly dab the spot or stain. Allow to dry. THANK YOU….. …..
