  • Industry: Residential Construction
  • Application: Window installation in rough openings
  • Shim Type: Plastic flat shims
  • Key Benefit: Reliable load support and precise window positioning

 

Overview

Proper support is critical during window installation. Before a window can be secured and finished, it must be positioned correctly and supported evenly within the rough opening.

Plastic shims provide a stable foundation that helps installers maintain alignment while supporting the weight of the window throughout the installation process.

In this project, Baywest Projects used Grove plastic shims to support residential window installations and ensure consistent positioning across multiple homes.

 

The Challenge

Residential window installations require a reliable support system within the rough opening before the window is fastened into place.

Key challenges included:

  • Supporting the weight of installed window units
  • Maintaining proper positioning during installation
  • Creating a stable base within the rough opening
  • Ensuring consistency across multiple residential builds

Without adequate support, windows can shift during installation, making alignment more difficult and increasing the potential for rework.

 

The Solution

Baywest Projects used Grove plastic shims in the rough openings to create a solid, level base for each window installation.

The shims were strategically placed to:

  • Support the load of the window unit
  • Maintain proper positioning throughout installation
  • Create consistent bearing points within the opening
  • Improve installation accuracy and efficiency

Because plastic shims provide consistent thickness and dependable support, installers were able to position windows confidently before final fastening and finishing.

 

Why Plastic Flat Shims Work

Plastic flat shims are designed to provide stable support and consistent spacing in load-bearing applications.

  • High load-bearing capability: Supports window weight during installation
  • Consistent thickness: Helps maintain proper positioning and alignment
  • Non-compressible: Provides reliable support without shifting
  • Multiple thickness options: Allows installers to level and position windows accurately
  • Versatile use: Ideal for windows, doors, framing, and general construction applications

These features make flat plastic shims a dependable choice whenever a stable bearing surface is required.

 

Results

Using plastic shims in this project helped:

  • Support the weight of installed windows during construction
  • Maintain proper positioning within rough openings
  • Create a stable base for installation
  • Improve consistency across multiple residential builds

Installers were able to work efficiently while maintaining alignment and structural support throughout the installation process.
