Nominal thickness of 3/4 plywood

If you are a DIY enthusiast working on woodworking projects, you must have come across plywood sheets of different thicknesses.

When you inquire or quote for plywood, you must state what thickness you will buy or sell clearly. Plywood thickness ranges from 0. But the common plywood is 3. Nominal Thickness is the thickness by which the is generally called or sold in trade, Actual Thickness means the real thickness of a plywood. Nominal Thickness and Actual Thickness are different.

Nominal thickness of 3/4 plywood

Plywood is a wood panel that is composed of several thin layers, or plies, of wood veneer. The wood is peeled from a log in thin sheets; different types of wood will yield different thicknesses of veneer. The veneers are glued perpendicular to each other, creating a cross-grain pattern that is much stronger than solid wood. Plywood sheet goods are available in various thicknesses and sizes and are typically sold by their nominal thickness, as well as by the number of plies — 3 ply and 5 ply being common. While the length and width are often the actual dimensions, the nominal thickness is usually different from the actual thickness. This introduces challenges when precision measurements are needed, such as determining clearance when using the plywood as an underlayment for flooring or countertops. Because the actual thickness may vary, measuring the plywood sheet using a caliper is the only accurate way to determine its thickness. The exception to this rule is plywood sheets that are over an inch thick. This may vary by manufacturer, though, so always check if you need a precise size or measurement. Keep in mind, that while many sheets of plywood are also sold by the number of plies, that veneers and plies can have different thicknesses as well, depending on the type of wood used. So, a 3 ply sheet — one of the most common — may measure 2mm or 3mm in thickness, depending on what wood was used in its manufacturing. It is important to keep in mind, that regardless of the thickness of the sheet, that the more plies it has, the stronger it will be. Likewise, if you are using plywood as an underlayment, you often need precise measurements of the height of the finished surface. For example, a floor may need to meet up with another material in an adjacent room; you need to know the exact thickness of the underlayment and the material on top to match it with the next space. There are a few reasons why the actual thickness of plywood varies.

While the length and width of a sheet is pretty straight forward, the thickness dimensions are anything but. The optimal plywood thickness mainly depends upon the dimensional requirements of the project and the type of application. DrRobert Replies.

If you are a DIY enthusiast working on woodworking projects, you must have come across plywood sheets of different thicknesses. These plywood sheets are available in grades, with A-grade being the best quality plywood and D-grade being the lowest quality option. This article will provide a detailed guide on plywood thickness and present a chart to help you select the right plywood according to its available thickness. When looking for the right plywood for your project, you should remember that plywood has two types of thickness: nominal thickness and actual thickness. Nominal thickness is the standard thickness that is generally mentioned in the description of the plywood. This is primarily because of the sanding operation performed on the sheets after manufacturing them.

This variation is considered standard within the industry. Additionally, some manufacturers may produce plywood that adheres more closely to the nominal thickness, so consulting the product specifications or contacting the manufacturer directly can provide more accurate information for a particular brand or type of plywood.

Thanks for all the replies. Luan plywood, also known as lauan plywood, is a special type of hardwood plywood made from tropical hardwood. Related Posts. Similarly, a plywood sheet's length is commonly eight-feet, but some suppliers carry four and twelve-foot lengths. All Rights Reserved. Softwood plywood may be thicker than hardwood plywood, due to the need for additional plies to lend stability and structure to the sheet.

These plywood are used for applications where good load capacity is desirable, irrespective of the surface finish. Metric thickness shown here are approximations.

Just how large is the space that you have to fill? Softwood plywood may be thicker than hardwood plywood, due to the need for additional plies to lend stability and structure to the sheet. The standard size of plywood sheets is 4' x 8' which covers a rectangular area of 32 sq. Long story short The optimal plywood thickness mainly depends upon the dimensional requirements of the project and the type of application. Top Contributors this Month View All. There are a few reasons why the actual thickness of plywood varies. The amount of glue will swell the wood slightly during manufacturing; it will then shrink as it dries. MFD boards are best suited for indoor applications like cabinetry, cupboards, desks, etc. First, wood shrinks as it dries and moisture leaves the wood. These solid veneers are bonded together with a strong adhesive, eliminating any voids in its core.
