Difference Between Softwood Plywood and Hardwood Plywood? Softwood Plywood
The most common size is 1.2 by 2.4 meters (3 ft 11 in 7 ft 10 in) or the slightly larger imperial size of 4 feet 8 feet. The thickness of plies ranges from 1.4 mm to 4.3 mm. The number of plies required depends on the thickness and grade of the sheet, but the minimum odd number of plies is three. The thinner 5/8 can be used for roofing "Plywood (15 mm) Subfloors are at least 3/4 inch thick "(18 mm) thick, with the thickness varying according to the distance between floor joists. When the joints do not lie over joists, plywood for flooring applications is often tongue and groove; this prevents one board from moving up or down relative to its neighbor, providing a solid feeling floor. Applications for Softwood Plywood
1. Spruce plywood is commonly used for floors, walls, and roofs in home construction. 2. Panels for wind resistance 3. Internal vehicle bodywork 4. Boxes and packages 5. Fencing 6. Coating solutions are available to conceal the visible grain structure of spruce plywood. There are some end uses for these coated plywood's where reasonable strength is required but the lightness of spruce is advantageous, for example: 7. Panels of concrete shuttering 8. Ready-to-paint construction surfaces. Hardwood Plywood
Hardwood plywood is made from angiosperm tree wood and is used for demanding applications. Hardwood plywood is distinguished by its high strength, stiffness, and creep resistance. It has high planar shear strength and impact resistance, making it ideal for heavy-duty floor and wall structures. The wheel-carrying capacity of oriented plywood construction
