Question

what is the diffrence between ply wood and laminated wood?
Thanks,

Answer 1

Wellll that's a bit like asking what's the difference between an automobile and a vehicle.... all automobiles are vehicles, but not all vehicles are automobiles. All plywoods are laminated wood, but not all laminated wood is 'plywood'.

One example of "laminated wood" and probably the most common, is laminated hardwood flooring. This is usually about 3/4" thick, and consists of 3 thick layers of wood. This is a common alternative to 'solid' wood....you can sand the floor down up to a quarter inch, if necessary, its more stable than solid wood, and costs less. (But its still more expensive than other forms of flooring, hehe).

Another example of laminated wood, is 2 ply veneers. Ive used some of these myself. Theyre 2 layers of veneer, running crosswise to each other, to add strength, and stability. But theyre still thinner than most greeting cards.

Plywood can come in many shapes sizes and forms.... usually we think of it in certain basic terms... 3, 5, or 7 layers, construction, exterior, or cabinet grade, etc. You can get it with specific veneers, like birch, or oak, or even in a 'bendable' form... literally, you can roll it in a tube ('Bendy' ply is the common name for this type... its 3 layers, and comes in two thickness options).

Another type that kind of blurs the lines between the two, is curved laminated shapes... for example, kitchen chairs...that top piece that runs across the back (many have a design embossed into them), is usually a laminated wood...it LOOKS a lot like plywood... but it is layed up in a bowed form, or mold, where plywood is generally a 'flat' product.

Perhaps you'd like to give a context to your question? We might be able to give some more specific details then.

Hope this helped

Answer 2

The technology of laminated wood consists in dividing the log into planks, which are then dried and sorted in degrees of quality. They to are then united together to form a ”laminate” about 33 millimetre thick. Finally they are glued together to form beams and structural elements in different sizes. They can be geometric in shape or take on any curved form.
Wood laminates improve upon the natural strengths of solid lumber and reduce or eliminate such inherent defects as warping, bowing and shrinkage. Precise lengths can be cut which are consistent in quality throughout the board or the panel, reducing waste and labour in a wide range of applications.

Plywood is manufactured by slicing or rotary peeling thin [<2.5 mm] sheets of material [veneer] from a flitch or log and then laminating three or more veneers into a rectangular sheet perhaps 1200 mm × 1200 mm for very thin sheets otherwise 1200 mm × 2400 mm. Laminating an odd number of plies [3, 5, 7 ...] reduces warping while increasing the number of plies increases the resistance to shearing forces.

Answer 3

Give the 10 to Wrangler. PLYwood is a laminate; just not a "Laminated" board used in finish flooring.

Actually "PLY" wood defines the lamination of various species; and was in existance and use; as far back as the Early Egyptians.

Answer 4

Ply wood is many thin layers of wood pressed together. You can see this by looking on the edges. Laminated wood is compressed saw dust with a lamination over it. If you want to build something and want it to last a few years use ply wood over laminated wood.

Compressed wood is little pieces of wood like chips and sawdust all glued together. Then it is usually covered with a photograph of wood to make it look nice. It's not too expensive but it won't last well when gotten damp, or when moved. There are higher grades, but still has a lifespan. Plywood is the next step up - thin sheets of wood are shaved off of the tree, then glued together to make a sandwich. These can last 50, even 75 years if kept dry and cared for - especially if it is a higher quality of plywood. You can make plywood furniture yourself - it's not hard. The highest step up is solid wood. I saw some the other day from the 1700's and they were still in excellent shape. My suggestion would be to just buy cheap used furniture for your needs, and use the savings to buy one really nice solid wood piece whenever you can afford it. They will last generations.
