Plywood for Interior and Exterior

Plywood is structural wood made by joining three or more layers of plies or veneer. After glueing, these plies are laid with the grain of adjoining plies at right angles. There are different Plywood for Interior and Exterior.

Plywood Consists Of:

• Face
• Core
• Back

The surface visible after installation is the face and the core lies between the face and back.

Plywood can be derived from:

1. Hardwood (such as teak or Gurjan wood).
2. Softwood (such as pine, cedar or mango wood).

Properties Of Plywood

1. High Strength

• Plywood has the structural strength of the wood it is derived from.
• To enhance strength and stability each ply is usually orientated at a right angle to the adjacent layer.
• Due to its higher strength to weight ratio, it is ideal for flooring, webbed beams, and shear walls.

2. High Panel Shear

• To make it tough to bend, Plywood is made with an odd number of layers.
• The panel shear of plywood increases due to cross lamination, important in bracing panels and web fabricated beams.

3. Flexibility

• For ceiling and panelling, thinner veneers improve flexibility.

4. Chemical Resistance

• Plywood is treated with preservatives so that it does not corrode when subjected to chemicals.
• These are ideal for use in chemical works as well as cooling towers.

5. Impact Resistance

• Plywood has high tensile strength due to cross lamination of panels.
• It helps against short term seismic activity or strong winds.

6. Fire Resistance

• With a fire-resistant chemical coating, Plywood can be made fire-resistant.
• Mostly, plywood is combined with non-volatile materials such as plasterboard or fibrous cement.
• Also, this makes it suitable for fire-resistant structures.

General Uses Of Plywood 

1. Structural

To make formwork, or moulds for wet concrete. 

In the construction of door frames, shear walls, bundling, and roof trusses

2. Interior Work

To make flooring, rooftops, and so forth 

To make furniture, particularly pantries, kitchen cabinets, and office tables. 

Also, to make segments or panelling. 

3. Exterior Work

Outside cladding, Fencing, Decking, Rails and Balustrades, Landscaping elements, Steps 

4. Miscellaneous Works

In the transportation business. 

In the production of space and aircraft parts. 

Kinds Of Ply 

1. 3-Ply:

This sort has three layers of veneer. 

Application: It is has a preferable appearance over plywood with more plies, making it valuable for indoor use. 

2. 5-Ply:

This sort has five layers of veneer. 

Application: It is utilized for projects that require less toughness and strength. 

3. Multi-Ply:

It can contain several veneers; normally at least seven, to make a solid, unyielding frame for a structure that can oppose winds and outer forces. 

Application: It is for the most part for outside use and roofing.

Plywood Types

1. As Per Wood Used 

Softwood Plywood:

Softwood like pine, redwood, or cedar. 

Application: Walls, roof sheathing, transitory ground surface, crates, boxes, and so forth

Hardwood Plywood:

Hardwoods like debris, oak, red oak, birch, maple and mahogany, in three to seven layers. 

Application: furniture, framing, partitions, and so forth 

2. As Per Usage 

Airplane Plywood:

It uses hardwoods, similar to mahogany or birch, to make a profoundly solid finished piece that can likewise oppose warmth and dampness. Moreover, the design consolidates incredibly slender veneers that can keep it light and adaptable while fortifying it for taking care of solid forces. 

Application: In projects that need modern strength woods, similar to planes, boats, and furniture which can hold a ton of weight. 

Lumber Core:

Application: The inward centre aides handle screws, which makes it ideal for projects that require a solid screw hold, for example, racks in cupboards or storage rooms. 

It is usually made with three plies, with two thin veneers (hardwood) on each side and a thick core (strips of wood).

Structural Plywood:

It can be made both of softwood or hardwood. 

Application: This wood discovers use in long-lasting designs requiring high strength like ground surface, radiates, formwork, and bracing panels. 

3. As Per Grades 

Moisture Resistant (MR) Grade:

Perfect to oppose dampness. 

(Note: Moisture Resistant doesn’t mean waterproof. It just implies that the plywood can oppose a specific measure of stickiness or moistness) 

Application: It is most suitable for furnishings, framing, parcels, and so forth 

Boiling Water Resistant (BWR) Grade:

It is equipped for resisting water. Phenolic resins add waterproofing characteristics to the plywood. 

Application: It is outside grade plywood that can be utilized for indoor, semi-outdoor air and outdoor use. It is generally utilized for making furniture that is probably going to get wet. 

Boiling Water Proof (BWP) Grade:

It is superior grade plywood which is better and stronger when contrasted with both MR and BWR grade plywood. This guarantees that the glue will not quit working if the wood becomes damp from climate or wet conditions. 

Application: It is the most ideal decision for marine applications, and discovers incredible use in the delivery and boat making industry. Besides, it is utilized for the most part for outdoor furniture and constructions like gazebos, planter boxes, kiosks and seats. 

Flexible Grade Plywood:

This kind of plywood isn’t solid and can be rolled without any problem. 

Application: It is useful in making bent or round shapes in furnishings. 

Fire Retardant (FR) Grade Plywood:

Its surface is treated with chemicals that hinder the burning process of wood. 

Application: It is utilized where fire chances should be minimized, for example, in shopping buildings, public theatres, cafés, kitchens, and so forth

Finishing Of Plywood 

1. Laminates: Beautifying covers or others (which are a mix of paper and plastic) are stuck over the plywood surfaces. 
2. Paints: To paint any plywood, a primer is first utilized, which will make the wood surface smooth and permit the paint to stick to it. Besides, it is a minimal expense option in contrast to laminates or veneers and offers a wide scope of colours. 
3. Polish: Wood finish is typically utilized on wooden furnishings. Wood finish (of darker shadings) is utilized on some furniture parts (like the underside of tables or the internal boards of single and double beds). 
4. Veneer: Wood veneers are dainty cuts/sheets of value woods, which can be stuck over the plywood surface to improve its excellence. Veneers are typically the costliest method of enriching plywood. 

Benefits Of plywood 

1. Great Uniform Strength: In plywood manufacture, the grains of connecting piles are laid at right angles, giving strength to the plywood sheets. 
2. Accessible In Huge Sizes Contrasted With Strong Wood: Consistently thick 18 mm plywood sheet of size 8×4 is effectively accessible, however, it is hard to get strong flat wood of such a size. 
3. Prudent Utilization Of Wood By Blending Different Woods: The veneers of such woods are perfect to frame the surface layer of the plywood, while the inward layers might include other solid yet less expensive woods. 
4. A Flexible Material That Has Numerous Applications: Other than home style and furniture, plywood has a few modern and primary applications. for example Marine plywood for boat-making and so on 
5. Durable Materia: Plywood furniture produced using great quality hardwood (like teak, gurjan or eucalyptus wood) is very sturdy and lasts several years.
