The Difference Between Square Edge and Tapered Edge Plasterboard

The Difference Between Square Edge and Tapered Edge Plasterboard

Plasterboard is a popular alternative to wet plastering for many construction and renovation projects these days. It offers several benefits and can help you to achieve a flawless finish, regardless of where it’s installed. Plasterboard is known for its versatility and there’s a huge range of materials on the market to choose from.

One big decision to make when ordering plasterboard for your project is whether you opt for square edge or tapered edge boards. This decision can significantly impact the project timeline and outcome, and it’s important to carefully compare these two options. In this post, we have explored the distinctions between these two types of plasterboard, helping you make an informed decision for your next project.

Understanding Plasterboard Edges

Plasterboard is a key component of wall, ceiling and partition projects, and it commonly comes in two edge profiles; square edge and tapered edge. The main difference between these two types of plasterboard is the board edges and they’re designed to suit different finishing techniques. The choice between these profiles not only affects the aesthetics of the final surface but also the approach to installation and finishing.

While square edge plasterboard is a traditional solution suitable for various applications, tapered edge plasterboard is ideal for projects requiring a high level of finish, particularly in smooth wall and ceiling surfaces. The versatility of products on the market ensures that regardless of your project’s specific demands, there is a plasterboard edge type suited to meet them efficiently.

Square Edge Plasterboard

Square edge plasterboard has uniform, straight edges. When installing this type of plasterboard, you will have a clear joint that needs to be covered. Professional skimming with a layer of jointing compound will help achieve a flawless finish.

Pros;

  • Versatility - Square edge plasterboard can be used in a variety of applications where the joints can be hidden with specific decoration.
     
  • Simplicity - Typically, this type of plasterboard is straightforward to install without the need for special techniques at the joints.
     

Cons;

  • Finishing Time - Due to the angle of the edges, it may require more time and material to achieve a smooth finish over the joints.
     
  • Limited Application - Square edge plasterboard isn’t always the best choice for smooth, painted finishes where joints need to be invisible.
     

Tapered Edge Plasterboard

Tapered edge plasterboard features edges that taper towards the end of the board, creating a slight groove when two boards are installed side by side. This design supports the seamless application of jointing compound and tape.

Pros;

  • Seamless Finishes - Tapered edge plasterboard is ideal for achieving smooth, flat surfaces that are ready for painting or wallpapering.
     
  • Reduced Joint Visibility - The tapered edges allow for easier filling and creating smoother transitions between boards.
     
  • Efficiency in Material Use - Typically, this type of plasterboard requires less joint compound to finish the seams, making it a cost-effective choice.
     

Cons;

  • Skill Level - Installing and finishing tapered edge plasterboard can require more skill to ensure that the tape and joint compound are applied correctly.
     
  • Cost - Tapered-edge plasterboard can be more expensive than square edge plasterboard, impacting the overall cost of your project.
     

Making the Right Choice

When choosing between square edge and tapered edge plasterboard, it’s key to consider your project's specific requirements and desired finish. For seamless, paint-ready surfaces, tapered edge plasterboard is a great choice, offering an efficient solution for creating invisible joints. It simplifies the finishing process, ensuring walls and ceilings have a smooth appearance.

On the other hand, square edge plasterboard is a versatile option for projects where the decorative finish will conceal the joints or when a textured surface is desired. It allows for greater flexibility in applications but may need additional effort and materials to achieve a smooth seam if a non-textured finish is required.
