Introduction

When installing exterior doors, ensuring they are level and properly aligned is crucial for security, energy efficiency, and overall functionality. Shims play a vital role in achieving this alignment. Traditionally, wooden shims have been the go-to choice, but plastic door shims are becoming increasingly popular. Are plastic door shims suitable for exterior doors? This article will delve into their suitability, benefits, drawbacks, and how they compare to traditional wooden shims.

Understanding Plastic Door Shims

What Are Plastic Door Shims?

Plastic door shims are thin, wedge-shaped pieces made from durable plastic materials. They are used to adjust the position and alignment of doors during installation, ensuring a snug fit and proper operation.

The Importance of Proper Door Alignment

Why Proper Alignment Matters

Proper door alignment is essential for:

• Security: Misaligned doors can be easier to break into.
• Energy Efficiency: Gaps around doors can lead to drafts and increased energy bills.
• Functionality: Misaligned doors can stick, drag, or fail to latch properly.

Benefits of Using Plastic Door Shims for Exterior Doors

Durability

Plastic shims are resistant to:

• Moisture: Unlike wooden shims, plastic does not absorb water, making it ideal for exterior use.
• Rot and Decay: They do not rot or decay over time.
• Insects: Plastic is impervious to insect damage.

Ease of Use

Plastic shims are:

• Uniform in Size: They offer consistent thickness and shape.
• Easy to Cut: Can be trimmed to size with a utility knife.
• Stackable: They can be stacked to achieve the desired thickness.

Longevity

Plastic shims maintain their shape and structural integrity over time, ensuring the door remains properly aligned.

Drawbacks of Plastic Door Shims

Flexibility Concerns

• Too Flexible: In some cases, plastic shims may be too flexible, leading to potential movement over time.
• Temperature Sensitivity: Extreme temperatures may cause plastic shims to expand or contract slightly.

Cost

• Higher Initial Cost: Plastic shims can be more expensive than wooden shims initially.

Comparison Between Plastic and Wooden Shims

Material Properties

• Wooden Shims: Prone to moisture absorption, rot, and insect damage.
