Using Plastic Shims for Precise Interior Window Installation

Project Snapshot

• Industry: Educational Construction
• Application: Interior punched window installation
• Shim Type: Plastic flat shims (3/8″)
• Key Benefit: Consistent spacing and secure alignment across multiple window types
  
  

Overview

Interior window installations in educational facilities require precision, consistency, and repeatability across a wide range of window types and framing systems.

Plastic shims provide a reliable way to maintain proper spacing and alignment, helping installers achieve consistent results across multiple openings.

In this project, M-TECH Glass used Grove plastic shims to standardize installation practices and improve overall efficiency and accuracy.

The Challenge

This project involved installing interior punched windows across an educational facility with varying window types and framing conditions.

Key challenges included:

• Ensuring precise alignment across multiple window openings
• Maintaining consistent spacing regardless of window type
• Providing reliable structural support during installation
• Achieving repeatable results across glazing and framing systems
  
  

Without a consistent approach, installers risk uneven alignment, inefficiencies, and inconsistent installation quality.

The Solution

M-TECH Glass used 3/8″ Grove plastic shims as a standard part of their installation process.

These shims were used to:

• Maintain consistent spacing between the window frame and structure
• Support proper alignment during installation
• Provide stable, non-compressible support across all openings
  
  

By standardizing shim selection and usage, installers were able to work more efficiently while maintaining accuracy across different systems, including:

• Interior punched windows
• Storefront systems
• Curtain walls
• Standard window installations
  
  

Why Plastic Flat Shims Work

Flat plastic shims provide key advantages in interior window installations:

• Consistent thickness: Ensures uniform spacing across all openings
• Non-compressible: Maintains alignment during and after installation
• Repeatable performance: Supports standardization across multiple window types
• Versatile use: Works across glazing, framing, and window systems
  
  

These benefits make plastic shims a dependable solution for projects requiring both precision and consistency.

Results

Using plastic shims in this project helped:

• Standardize shim usage across all glazing and framing systems
• Improve installation efficiency and speed
• Increase alignment accuracy across multiple window types
• Deliver consistent, reliable results on every installation
  
  

Installers were able to achieve repeatable, high-quality outcomes across the entire project.
