Using Plastic Horseshoe Shims for Exterior Panel Installation & Alignment

Project Snapshot

• Industry: Residential Construction
• Application: Exterior panel installation and alignment
• Shim Type: Plastic horseshoe shims
• Key Benefit: Precise spacing and alignment around anchors and fasteners
  
  

Overview

In exterior panel installations, maintaining consistent spacing and alignment is essential for both performance and appearance.

Plastic horseshoe shims allow installers to position panels accurately around anchors and fasteners, making it easier to achieve a clean, uniform finish while supporting proper system performance.

Used in a 5,000 sq. ft. off-the-grid residential project, Grove plastic horseshoe shims helped ensure precise alignment and consistent spacing across the entire exterior.

The Challenge

This project required installing fiber exterior panels on a large residential structure with strict design and performance requirements.

Key challenges included:

• Maintaining consistent spacing across all panels
• Ensuring proper airflow behind the exterior system
• Allowing for thermal movement and expansion
• Aligning materials around anchors and fastening points
• Achieving a clean, visually consistent finish
  
  

Even small inconsistencies could affect both the appearance and long-term performance of the system.

The Solution

Plastic horseshoe shims were used to support alignment and spacing throughout the installation.

Offsetting aluminum rails from the structure

Horseshoe shims were placed around anchor points to create a consistent gap between the rails and the wall. This helped:

• Maintain proper airflow behind the panels
• Allow space for expansion and movement
• Improve overall system performance
  
  

Aligning exterior panels

The open-center design of horseshoe shims made it easy to install them around fasteners, allowing for:

• Consistent spacing between panels
• Straight, even alignment across the façade
• Efficient installation without repositioning fasteners
  
  

This approach allowed installers to maintain precision across a large surface area.

Why Plastic Horseshoe Shims Work

Plastic horseshoe shims are designed for applications where alignment around fasteners is required:

• Open-center design: Fits around bolts and anchors without removal
• Consistent thickness: Ensures uniform spacing and alignment
• Color-coded thicknesses: Many options for quick identification and adjustment
• Multiple sizes: Available in 3″×4″ and 4″×6″ formats
• Vertical and horizontal use: Ideal for panel, glass, and storefront applications
  
  

They are commonly used in:

• Precast and tilt-up construction
• Glass and façade systems
• Exterior panel installations
  
  

Results

Using plastic horseshoe shims in this project helped:

• Achieve precise, consistent panel alignment
• Maintain proper airflow behind the exterior system
• Simplify installation around anchors and fasteners
• Improve installation efficiency across a large project
• Deliver a clean, high-quality exterior finish
  
  

Installers were able to work faster while maintaining accuracy and consistency.
