Sliding Glass Doors – How to Choose the Right Door for You - CWE

Your Step-by-Step Guide from Coastal Windows & Exteriors

When it comes to replacing your sliding glass door, the number of options available can feel overwhelming. But don’t worry—we’ve made the selection process easier with this complete guide to help you make the best decision for your home.


Why Sliding Glass Doors Matter

Over the past 15 years, sliding glass doors have evolved significantly. New models offer enhanced security, superior energy efficiency, and customizable beauty. Choosing a high-performance door ensures durability, safety, and long-term value.


Key Sliding Glass Door Features to Consider

1. Material: Vinyl vs. Wood

Premium Vinyl (PVV or Pure Virgin Vinyl)

  • Never chips, peels, cracks, or warps

  • Doesn’t require painting

  • Maintenance-free and built to last

Wood Doors

  • Prone to swelling and rot over time

  • Requires regular painting and upkeep

  • Not ideal for long-term durability

Pro tip: Choose premium vinyl to avoid future maintenance headaches.

2. Style Options and Rail Sizes

Choose from:

  • Standard 3” or 5” rails all around the door (5” rails shown in the Preservation Collection example)

  • French Style with 5” top rails and 7” bottom rails for an authentic, space-saving look

You can also add character with:

  • Decorative glass grids

  • V-grooved cut glass patterns

3. Interior and Exterior Color Options

Modern sliding doors come in a range of color combinations that allow you to match both your home’s interior and exterior styles.

4. Security Features That Matter

Strong security is a must. Look for sliding doors that include:

  • Steel hook locks for a tight, energy-efficient seal

  • Interlock systems with anti-lift features to prevent forced entry

  • Hand and foot locks for added protection—without unsightly bars or dowels

Stay safe without compromising on style.


5. Glass Technology for Energy Efficiency

  • 1” thick insulated glass units

  • SST warm-edge spacer systems to minimize heat and cold transfer

  • Enhanced durability for long-term performance

This type of glass helps reduce energy bills year-round and is far more durable than standard glass.


6. Weatherstripping and Track Design

  • Dual internal/external weatherstripping for maximum insulation and performance

  • Stainless steel roller tracks that resist buildup and avoid the dark, worn streaks common in aluminum tracks


7. Professional Installation Is a Must

Even the best sliding glass door won’t perform well if it’s poorly installed. To get the full benefits, always choose a certified window and door technician for installation.


Final Thoughts: A Door That Works as Hard as You Do

As a result, today’s sliding glass patio doors are smarter, stronger, and more beautiful than ever. By carefully considering the key features—material, style, security, energy efficiency, and professional installation—you’ll make a lasting investment that enhances both your comfort and your home’s value.
