Which of the following statements related to laminates of building materials is correct?
1) A wood panel glued under pressure from an odd number (usually 3 to 13) of layers/piles of veneers is known as plywood.
2) The process of producing thin sheets of 0.4 mm to 0.6 mm thickness wood for the manufacture of wood products is known as veneers.

Correct option is B

Three or more veneers in odd numbers are placed one above the other with the direction of grains of successive layers at right angle to each other.
Plywood is obtained by gluing wooden sheets at pressure of 100 to 150 kg/cm2 and a temperature of 100 to 130 degrees Celsius. Plywood is made up of three or more thin layers of wood.
It has good strength both along as well as across the grains.

The wood shrinkage or swell more across the grains. Since plywood has cross-grained construction, the tendency to shrink or swell is reduced.
The process of producing thin sheets of 0.4 mm to 0.6 mm thickness wood for the manufacture of wood products is known as veneers.
