Finger Jointed Panels
Finger Jointed Laminated Boards - A Solid Solution


[Zoom] 		Finger Jointed Laminated Boards can be used to make joinery material, beams, table tops, parquet flooring and for other panel applications. Finger Jointed Laminated Boards offer a solution to the increasing shortage of solid timber panels. The timber is kiln dried to a moisture content below 10%, planed and ripped to thinner strips. These strips are finger jointed after color matching to the desired lengths and then edge coated with special resins, which can withstand boiling water tests.
The coated strips are edge laminated applying pressure from the sides AND top in a composer press to form panels. These panels are sanded to produce finished solid lumber panels. Machining these panels can be done exactly the way solid lumber is machined. mahaghonyboard

Specifications
The treated Wood for Finger jointed solid wood panels is pressure impregnated with Boric- Borax Parachem Anti-Bacterial Chemicals, kiln dried & normalized. The grade specification is applicable to 1 face & 2 edges and the other face will have the specification with minor defects of the next lower grade. The Resins for edge gluing & Finger Jointing are polymers (PVAC, PU Combinations), which are either white or translucent. The glue joints are designed to withstand delamination tests conducted after boiling.
The depth of chemical impregnation is usually above 70% and is measured by reagents. The toxicity level of the product is low and within allowable limits.

The maximum dimensions of panels are: Length 6000mm, Width 1200mm, and Thickness 60mm.

Finger Jointed S4S Timber - Longer Lengths Reduce Wastage

[Zoom] 		Finger jointed S4S Timber can be used as Door & window frames, partition & false ceiling framework, furniture, beams & purlings (either with or without lamination). Finger Jointing is a modified butt joint where shear force is made to transmit compression or tension in wood member. The fingers are usually cut at a fibre slope of 1: 8 & the cut fingers are glued with special resins & then interlocked with pressure to produce longer lengths.
To achieve high strength, normally the glue area is designed to have around 6 times the cross-section area of the timber. The timber for jointing is dried to maintain proper moisture content. The joint could be oriented with the finger designs visible at the timber edge or on the flat side. From the point of view of strength, both these considerations are the same.

Applications
Furniture - Furniture suitability coefficient for rubberwood is calculated to be 69. Hence rubber wood is classified and standardized, as a Group III species in IS 13622:1993. (Indian timbers for furniture and cabinets- classification.)
Kitchen furniture - decorative and utility household items such as salad bowls, knife blocks, bookshelves, trays, magazine racks etc.
Flooring- Rubberwood has been successfully used for wooden flooring in offices, homes etc.
Building Components- Rubberwood has been using for making doors, windows, steps, railings, balusters etc.
Interiors - Paneling, mouldings, beadings, skirting, edging, parquet and strip flooring
Laminated Veneer Lumber - Rubberwood is being used for making LVL, which is a new wood based panel product in India.
Veneer and Plywood - Rubberwood can easily be peeled into uniformly thick, smooth and tight veneers and is reportedly suitable for making commercial plywood. Rubberwood veneers after proper treatment with preservative is widely used as plywood core stock.
Packing Cases - Rubberwood is a widely used timber for making packing cases. It has a packing cases suitability figure of 89 and is classified as Grade II in IS: 6662-1993. (Timber species suitable for wooden packaging specification).
Wood Carvings - Rubberwood has been widely used for making carved, decorative and utility items like ornament boxes, utility boxes, lacquered items trays etc.
