LITERATURE STUDY TOPI C - BOARDS BMCT VII Presentation by: Sagi Aakash Varma Sapavath Lokeshwar Nayak Pallavi Sudhakar Ojas Shirpurkar FIBERBOARD : FIBERBOARD IS ENGINEERED WOOD SHEETS MADE FROM VARIOUS MATERIALS, SUCH AS RECYCLED PAPER, WOOD WASTE, HARDWOOD, AND SOFTWOOD FLAKES, AS WELL AS SAWMILL OFF-CUTS. IT IS USED IN VARIOUS APPLICATIONS, SUCH AS LOWSLOPE ROOFING, STRUCTURAL SHEATHING, SOUNDPROOFING, AND FLOORING UNDERLAYMENT. THERE ARE THREE MAJOR TYPES OF FIBERBOARD WITH VARIED DENSITIES— PARTICLE BOARD, WHICH HAS THE LOWEST DENSITY, MEDIUM-DENSITY FIBERBOARD (MDF), AND HIGH-DENSITY FIBERBOARD. PARTICLE BOARD : PARTICLEBOARD IS COMPOSED OF WOOD FLAKES MIXED TOGETHER USING A RESIN SOLUTION SUCH AS MELAMINE BASED RESIN. IT HAS A DENSITY OF 160-450 KG/M³ AND IS USED IN VARIOUS CONSTRUCTION PROJECTS SUCH AS UNDERLAYMENT IN BATHROOMS, LAUNDRIES, AND KITCHEN FLOOR COVERINGS AS WELL AS IN FURNITURE DESIGN. PARTICLEBOARD IS THE WEAKEST AND LIGHTEST AMONG THE FIBERBOARDS AND IS PRONE TO DISCOLORATION AND WARPING WHEN EXPOSED TO HIGH MOISTURE. MDF (MEDIUM DENSITY FIBERBOARD) : MEDIUM-DENSITY FIBERBOARD IS ANOTHER TYPE OF FIBERBOARD COMPOSED OF FLAKES OF HARDWOOD AND SOFTWOOD COMBINED BY APPLYING A RESIN BINDER AND WAX WITH A DENSITY RANGING FROM 600-800 KG/M³. IT IS COMMONLY USED IN THE SHOPFITTING BUSINESS, LOUDSPEAKER ENCLOSURES, AND ON SCHOOL PROJECTS. MDF IS MUCH DENSER THAN CONVENTIONAL PLYWOOD AND IS OFTEN USED AS A SUBSTITUTE TO PLYWOOD WHERE GREATER STRENGTH AND FLEXIBILITY ARE REQUIRED. GREEN MDF IS MOISTURE-RESISTANT, YELLOW MDF IS NUCLEAR RESISTANT, AND BLUE AND RED MDF IS FIRE RESISTANT. HIGH-DENSITY FIBERBOARD : ALSO CALLED HARDBOARD, HIGH-DENSITY FIBERBOARD IS MADE OF HIGHLY COMPRESSED WOOD FIBERS THAT ARE MUCH DENSER, HARDER AND STRONGER COMPARED TO PARTICLEBOARD AND MEDIUM-DENSITY FIBERBOARD. WITH A DENSITY OF 600-1450 KG/M³, HIGH-DENSITY FIBERBOARD IS IDEAL FOR HIGH-QUALITY FURNITURE, FLOORING, CABINET-MAKING, AUTOMOBILE DASHBOARD PANELS, AND CONSTRUCTION PROJECTS. HIGH-DENSITY FIBERBOARD : ONE OF THE MAIN ADVANTAGES OF A HIGH-DENSITY FIBERBOARD IS ITS MOISTURE RESISTANCE. THIS IS NOT TO SAY THAT HDF IS TOTALLY WATERPROOF, THOUGH. HIGHDENSITY FIBERBOARDS ARE MOISTURE RESISTANT, BUT NOT WATERPROOF. HIGH-DENSITY FIBERBOARD HAS NO NATURAL WOOD GRAIN IT IS COST FRIENDLY TYPES OF FIBER BOARDS I NS UL ATI NG F I B E R B OARDMADE FROM THREE TYPES OF FIBER - WOOD, SUGAR, ASBESTOS, AND BINDER, FORMED INTO A BOARD. THERE ARE TWO TYPES OF GRADES : INSULATING GRADE IS MADE UP FOR INSULATING, DECORATIVE PANELSAND CEILINGS TILES. SHEATHING GRADE IS WHERE SURFACES AND EDGES ARE COATED WITH ASPHALT AND OR WITH FIBRES IMPREGNATED WITH ASPHALT DURING MANUFACTURING. TYPES OF FIBERBOARDS MINERAL FIBERBOARD : MADE FROM AS BESTOS FI BERS MI XE D WI T H CEMENTI NG AGENT I DEAL FOR F I RE PR OOFI NG AN D ACCOUSTI C AL PUR POSES. CANE FIBERBOARD : S HR EDDED C AN E AND PROCES S E D I NT O F I BRES GYPSUM BOARDS: IT IS A PANEL PRESSED BETWEEN TWO THICK SHEETS OF PAPER. IT IS USED TO MAKE INTERIOR WALLS AND CEILINGS. IT IS FIXED USING GLUE, ALUMINIUM OR PLASTIC MOLDINGS. STRAW BOARDS: MADE UP OF COMPRESSED WHEAT STRAW, PROCESSED AT 350-400 DEGREE F. IT IS MADE UP OF 100% WASTE STRAWS. USED FOR NON-BEARING PARTITIONS, PLASTER BASE, ROOF DECKING, EXTERIOR SHEATHING AND OTHER INSULATION PURPOSES. ASBESTOS CEMENT BOARDS: IT IS A DENSE AND RIGID BOARD THAT CONTAINS HIGH PROPORTION OF ASBESTOS FIBERS BONDED WITH PORTLAND CEMENT. IT IS FIRE AND WEATHERING RESISTANT. USED AS CORRUGATED SHEETING. SCREWS, BOLTS SANDS AND OTHER FASTENERS SHOULD BE USED IN INSTALLATION. PLASTIC FOAM BOARDS: MADE FROM POLYSTERENE AND POLYURETHANE PLASTICS THAT ARE 40 TIMES ORIGINAL VOLUME. THE FOAMED MATERIAL IS MOULDED INTO BOARDS FROM 0.5-3 INCH THICK BOARDS. USED FOR INSULATION OF CONCRETE SLABS, WALLS AND ROOF-DECKS. THESE BOARDS HAVE HIGH COMPRESSIVE STRENGTH AND HIGH INSULATION VALUE. FIRE RESISTANT BOARD (FR BOARD): FIRE RESISTANT GYPSUM BOARDS OR ALSO KNOWN AS FR BOARDS OFFER EXCELLENT FIRE PROTECTION DUE TO ITS SPECIALLY MADE CORE WHICH HAS LOW CONDUCTIVITY AND HIGH HEAT ABSORPTION. THE CORE OF FR BOARDS CONSISTS OF AERATED GYPSUM, GLASS FIBER AND ADDITIVES . FIRE RESISTANT BOARDS CAN RESIST FIRE BETWEEN 60 TO 120 MINUTES DEPENDING UPON THEIR THICKNESS AND INSTALLATION PROCESS. THEY CAN BE USED IN BOTH RESIDENTIAL AND COMMERCIAL SPACES SUCH AS OFFICE SPACES, KITCHENS, SERVER ROOMS, INVERTER ROOMS ETC.

Butt Joint: The end of a timber board is called the “butt.” Woodworkers forming this joint are placing two ends together at a right angle to create a corner. Mechanical fasteners such as nails or screws are necessary to preserve this joinery. TYPES OF JOINTS: 2. Mitered Butt Joint (Miter Joint): This joinery option connects two butts that get cut at an angle. The advantage of using this approach involves the strength of the corner. We get a seamless look that does not show any end grain. TYPES OF JOINTS: 3. Half-Lap Joint: Woodworkers use this joint to join two boards together to create a flush surface. It used most often when a connection is needed in the middle of the timber, although corner connections are also possible. Cross-lap Joinery: If the joint forms in the middle of both boards, it is called a cross lap joint. TYPES OF JOINTS: 4. Biscuit Joint: Woodworkers use this technique to create a more robust version of the butt joint using tongue and groove principles. Both ends of the timber get a slot cut into them to hold a small wafer that acts as a connection. When the glue gets added to the insert, it starts swelling until the entire carved-out area gets filled. TYPES OF JOINTS: 5. Half-Blind Dovetail: Most drawers use this joint design because it features a trapezoid design for the pins that fit together at the end of the timber. Woodworkers use it to avoid having the connection visible from the front of the piece without compromising their work’s strength. TYPES OF SCREWS: PAN HEAD SCREWS FLAT HEAD SCREWS WASHER HEAD SCREWS These heads have a rounded top and a flat underside. These screws are best for attaching sheet metal, Plexiglass or other thin materials to a piece of wood. The flat underside sits on top of the surface to hold everything together. These screws have a flat top and a cone-shaped underside, allowing the head to sink into the wood and sit flush to the surface. These screws have a rounded head with a builtin washer. They also have a flat bottom. Washer head screws are commonly used in pocket hole joinery, because the washer part fits into the predrilled hole and holds the two boards together tightly. DIFFERENT DRIVE TYPES (OR DRILL BIT SHAPES): PHILIPS HEAD STAR HEAD OR TORX SLOTTED OR FLATHEAD This head looks like a cross. You're likely familiar with this style. While better than slotted (flathead) drives, Philips head screws tend to bounce out or strip as torque increases. These are many woodworkers' favorite screws. The star head screw looks like a star with six points. It withstands high torque These screws have a single slit across the top to be used with a flathead screwdriver. MAKING OF PLYWOOD: Plywood panels are fabricated from multiple layers or plys of softwood veneer glued together with the grain direction of each layer of veneer perpendicular to that of the adjacent layers. These cross-laminated sheets of wood veneers are fastened together with a waterproof phenol-formaldehyde resin adhesive and cured under heat and pressure. manufacturers produce a range of plywood products for structure and non-structural uses suitable for both wet and dry service conditions, including subflooring, single-layer flooring, wall, roof and floor sheathing, structural insulated panels, webs of wood I-joists and concrete formwork. HOW DOES PLYWOOD COMPARE TO OTHER PRODUCTS? Plywood MDF Costlycompared to MDF cheaper than plywood weighs less weighs more than plywood More strength Less strength Not much dust is created MDF creates more dust when cut Need to finish the edges of plywood easy to cut, even along the edges plywood is great for stains MDF takes well to paint Boards Plywood Particle Board Materials Resin, Glue, Lumber, etc Thickness Density Property MDF Gypsum Board Cement Board wood chips, sawdust, wooden shavings, etc wood fibre, glue, etc crushed natural gypsum ,recycled paper, water and additives cement, fillers, cellulose 3, 4, 6, 8, 12, 15, 18, 21, 25 mm 9, 11, 12, 17, 18 mm 3, 4.75, 6, 9, 12, 16, 18, 25, 32 mm 6 to 25 mm 6 to 40 mm 500 - 650 kg/m3 0.2–0.3 g/cm3 600–800 kg/m3 600 to 1000kg/m3 350 - 570kg/m3 75-95 rs/ sq.ft 98 rs/ sq.ft 55 rs/ sq.ft 12 rs/ sq.ft 24 rs/ sq.ft Fire resistant Water proof Moisture resistant Price THANK YOU Presentation by: Sagi Aakash Varma Sapavath Lokeshwar Nayak Pallavi Sudhakar Ojas Shirpurkar
