Understanding the Thickness of Shuttering Plywood

Shuttering plywood, also referred to as film faced or sheathing plywood, is a popular construction material used in a wide range of applications, from concrete formwork to other building structures. One of the important factors to consider when working with this material is its thickness. In this blog post, we’ll delve into what shuttering plywood thickness means for your construction projects.

What is Shuttering Plywood?

Before we get into details about the thickness, let’s quickly understand what shuttering plywood is. This type of plywood is designed to be durable and robust, capable of withstanding the harsh conditions of construction sites. It’s often coated with a film of resin to make it resistant to moisture, making it an excellent choice for outdoor and indoor use.

Common Thicknesses of Shuttering Plywood

Shuttering plywood comes in a variety of thicknesses to suit different uses. The thickness you choose will depend on the specific requirements of your project.

The most common thicknesses available are 9mm, 12mm, 15mm, 18mm and 21mm1. Among these, 12mm and 18mm are the most commonly used in construction projects due to their optimal balance between weight and strength.

Why Does Thickness Matter?

The thickness of your shuttering plywood has a direct impact on its strength and durability. Thicker plywood is generally stronger and can support more weight, making it suitable for heavy-duty applications such as concrete formwork.

On the other hand, thinner plywood is lighter and easier to handle, but it may not hold up as well under heavy loads. Therefore, choosing the right thickness is crucial to ensure the safety and success of your project.

How to Choose the Right Thickness

When selecting the thickness of your shuttering plywood, consider the following factors:

  1. Load Capacity: If your project involves heavy loads, opt for thicker plywood.
  2. Ease of Handling: If the plywood needs to be moved frequently or installed by hand, thinner plywood may be more practical.
  3. Project Type: For structural projects, thicker plywood is usually better. For decorative or non-load-bearing projects, thinner plywood may suffice.

Wrapping Up

Understanding the thickness of shuttering plywood is a vital aspect of planning your construction project. It plays a significant role in the plywood’s strength, durability, and ease of handling. Always consider your project’s specific requirements when selecting the right thickness. And remember, it’s always best to consult with a professional if you’re unsure about the best choice for your project.
