•Panelling is a blanket term for wall coverings constructed from rigid or semi rigid components. These are traditionally interlocking wood, but could be plastic etc.•The panels served to insulate the room from the cold stone. In more modern buildings, such panelling is often installed for decorative purposes.• Panelling, such as wainscoting and boiserie in particular, may be extremely ornate and is particularly associated with 17th and 18th century interior design, Victorian architecture in Britain, and its international contemporaries
Paneling may be applied to drywall, directly to wall
studs, or to furring strips applied over masonry
surfaces
WOODEN PANELINGWood panels offer a thickness range from 3 mm to 43 mm; they
can be painted, wood veneered and polished, or factory finished with foils and decorative overlays
With time, more technically suitable acoustic panels replaced the wood panel cladding concept. Also, with air-conditioners and sophisticated heating systems being used extensively, the purpose of wood in maintaining temperatures too became irrelevant
There are many examples of hardwood panelling in old buildings especially those in cooler climates. Although work of the same character is only occasionally adopted in new buildings, one cannot disregard the contribution these examples have made to this pleasing form of internal surface covering. It is difficult now to surpass the hand craftsmanship and elegance of the earlier panelling, but the same skills and treatment are still required in alteration, conversion and restoration work There are several methods of securing the panel framing to the grounds.

MODERN WOOD PANEL INSTALLATION Horizontal panelling may be fixed with nails and/or stud
adhesive directly to the common wall studs while, vertical panelling will need added horizontal support, in the form of nogging (blocking) between the studs or full battens over the face of the wall. The smoothness of the finished panelling will depend largely on the straightness and spacing of the supporting Embers. Table below provides a guide to maximum support spacings.

TYPES OF WOOD
Wainscot or wainscoting is a panelling style applied to the lower 1.2 to 1.5 m of an interior wall, below the dado rail or chair rail and above the skirting board or baseboard. It is traditionally constructed from tongue-and-groove boards, though beadboard or decorative panels (such as a wooden door might have) are also common. Wainscoting may also refer to other materials used in a similar fashion.
Its original purpose was to cover the lower part of walls which, in houses constructed with poor or nonexistent damp-proof course, are often affected by rising dampness. Though some countries may impose building regulations for adequate damp-proofing, its purpose is now generally decorative.
Boiserie (often used in the plural boiseries) is the term to used to
define ornate and intricately carved wood panelling. Early
examples of boiseries were unpainted, but later the raised
mouldings were often painted or gilded. Boiseries were popular in
17th and 18th century French interior design and the Palace of
Versailles has many fine examples. The panels were not
confined just to the walls of a room but were also used to
decorate doors, frames, cupboards and shelves. Often pictures would be set into the
boiseries, the carving framing the picture rather like a conventional
frame.

Block Boards are made from a combination of suitable seasoned solid wood core and decorative face veneers. Seasoned to a moisture content and chemically treated for termite resistance. PF resin is used for bonding in the hot press process. All core battens are made from well selected hardwoods, strictly 25mm wide, placed horizontally and glued laterally to form the core which is covered with a cross band.
Also available in Commercial, Decorative, Super white and Neo Teak grades

BLOCK BOARD
Wood Wool Cement Boards (WWCB) or Excelsior boards are manufactured from long strands of chemically stabilized wood fibres(cut from debarked spruce or pine logs) coated in portland cement.
Available in boards of sizes 4’ X 2’ and 18 and 25 mm thick, they should be stored flat and kept dry.
ADVANTAGES
Its inherent resistance to fire and termite attack (a steel or timber framed wall faced with wood wool slab on both sides has a resistance of 1 hour)
Acceptance of wide range of finishes -the surface can be plastered and all coating materials including bitumen can be applied over it.
Wet and dry rot resistance
Good sound absorbing and sound insulation properties
Due to its medium density (300-500 kg/m3) and open texture, it is used in spaces where acoustical treatment is required.

WOOD WOOL CEMENT BOARD
Medium Density Fiberboard (MDF) is a wood based composite material that draws on the usage of wood fibers, rather than particles or veneers and involves addition of adhesives, usually urea formaldehyde, to the dry wood fibers slightly compressed to a density of at least 750 kg/cu.m. and cut to board length.
SIZES AVAILABLE 8’ X 4’ , 7’ X 4’ , 6’ X 4’ , 7’ X 3’ , 6’ X 3’
It is typically made as a board type product, though it is use in moldings. Its advantages include
high strengths,
ease of machining,
good weathering properties
Water proof
Termite and fire resistant
and the ability to be made from a wide variety of fibrous products (an environmental plus).
MEDIUM DENSITY FIBRE BOARD
Powder board is mainly made from sawdust bonded with adhesives to form boards (sheets) by
applying mechanical pressure and heat.
Properties of powder board
Powder board have a low strength, good fire resistance and air tightness.
Humid tolerant grades are resistant to occasional wetting.
Paper and plastic finishes are available.
As it is well compressed it is a good material to be used for sound insulation
Powder board is available in the market in the size of tiles also i.e. 2’ X 2’ priced at Rs. 26 per tile.
POWDER BOARD
Particle board is made from chips of timber bonded with urea formaldehyde resins to form boards (sheets) by applying mechanical pressure and heat.
Particle Board is a reconstituted wood panel product. Wood or agro residue is converted in to chips in the process of chipping and milling. This is followed by drying where excess moisture is reduced and uniformly controlled. Dried chips are mixed with synthetic resin in the mixing process, thereby forming chips mats of three layer constituency. the Particle mats are pressed and boards are cured in a heated pres thore with a temperature up to 180 degree and then boards are trimmed to desired size and thickness. Particle boards are finished with laminates on both sides.They available in boards of sizes 8’ X 4’ and of thickness 8,12 and 18 mm
PARTICLE BOARD
Stones have always been a favorite of the designers for the purpose of floorings, wall claddings and ornamental works due to the following factors:
the visual and aesthetic appeal of the stone,
availability of a wide variety of stones in abundance,
attractive and durable,
Strong and water-resistant
Scratch and stain proof
STONE PANELING
TYPES OF STONES
Fixing of stone by metallic clamps • It is the best way of cladding stone on external surfaces.•This involves rough plastering the surface which is to be cladded.•Clamping the stone with stainless steel or gun-metal clamps.•Pasting the stone with cement mortar (1:4).•Thicker stone have to be used for clamping.•Costs of fixing are up to Rs. 40/sqft.
