Exterior Doors

A Homeowner’s Guide to Exterior Doors and Associated Products

Exterior doors are a key component of your home’s security, Energy Efficiency, and visual appeal. They not only create a first impression but also offer functionality, such as protecting your home from weather and providing access to outdoor spaces. With various door types available, including traditional hinged doors, Sliding Doors, and modern accordion-style doors like a NanaWall system, it’s important to select the right style and material to suit your needs.

This article explores different types of exterior doors, including the increasingly popular accordion doors, along with associated products and materials to help you make an informed choice.

Types of Exterior Doors

1. Wood Doors

Wood doors are timeless and bring warmth and elegance to any home. They are available in various wood species, such as Mahogany, oak, and Pine, and can be custom-stained or painted.

Uses:

  • Main entry doors

  • Custom, decorative entryways

Benefits:

  • Beautiful, natural aesthetic

  • Customizable with Stain or paint

  • Excellent insulation properties

Considerations:
Wood doors require regular maintenance to prevent warping, cracking, and weather damage. They are also more expensive than other materials and need refinishing to maintain their appearance over time.

2. Steel Doors

Steel doors are highly durable, providing superior security and insulation. They are typically constructed with a foam core covered by a steel outer layer.

Uses:

  • Main entry doors

  • Garage entry doors

Benefits:

  • Very secure and durable

  • Energy-efficient

  • Affordable and low maintenance

Considerations:
Steel doors can dent or scratch, and if the finish is damaged, they may rust. While strong, they offer fewer design options compared to wood or Fiberglass.

3. Fiberglass Doors

Fiberglass doors are popular for their low maintenance, durability, and ability to mimic the appearance of wood. They resist dents, warping, and moisture damage, making them ideal for harsh climates.

Uses:

  • Main entry doors

  • Homes in coastal or humid environments

Benefits:

  • Extremely durable and weather-resistant

  • Low maintenance

  • Can be made to look like wood

Considerations:
Fiberglass doors can be more expensive than steel doors, but their longevity and low upkeep often justify the cost.

4. Glass Doors

Glass doors or doors with large glass inserts offer natural light and modern design. They can range from fully glass to half-glass designs and often feature decorative or privacy glass.

Uses:

  • Patio Doors

  • Front entry doors with glass accents

Benefits:

  • Brings in natural light

  • Creates a sleek, modern look

  • Available with energy-efficient double or triple-paned glass

Considerations:
Glass doors may reduce privacy and security unless reinforced or paired with laminated or Tempered Glass. They may also require more frequent cleaning and offer lower insulation unless specialized glass is used.

5. Sliding Patio Doors

Sliding patio doors are a space-saving option for accessing decks, patios, and outdoor spaces. They provide large glass panels that offer unobstructed views and easy access to outdoor areas.

Uses:

  • Patios and balconies

  • Outdoor entrances to decks or gardens

Benefits:

  • Saves space as the doors slide rather than swing

  • Large glass panels offer natural light

  • Provides a modern, open look

Considerations:
Sliding doors may require regular maintenance to keep the track free of dirt and debris. They can also be less secure than hinged doors without additional locking mechanisms.

6. French Doors

French doors feature glass panels extending the length of the door, often used in pairs to create a wide opening. They are typically used to connect indoor living spaces to patios or gardens.

Uses:

  • Patios and balconies

  • Main entryways

Benefits:

  • Elegant, traditional design

  • Allows natural light to enter

  • Can be used as an indoor-outdoor transition

Considerations:
French doors require more space to open fully and may need additional security features, especially if they have large glass panels.

7. Accordion Doors (NanaWall or Folding Glass Walls)

Accordion-style doors, such as NanaWall systems, are a modern option that provides a seamless transition between indoor and outdoor spaces. These doors fold open like an accordion, allowing for expansive, unobstructed views and access to the outdoors.

Uses:

  • High-end patios, decks, or balconies

  • Homes with a focus on indoor-outdoor living

Benefits:

  • Maximizes the opening to outdoor spaces

  • Provides a modern, sleek design

  • Offers energy-efficient options with Insulated Glass

Considerations:
Accordion doors are more expensive than traditional doors due to the complexity of the system and materials. Installation requires precise measurements, and regular maintenance is needed to keep the sliding and folding mechanisms working smoothly. These systems may also need reinforced framing to support the larger glass panels.

Associated Products and Materials

1. Door Frames and Jambs

Door frames and jambs provide the structural support for exterior doors. Properly installed frames are essential for the door to function smoothly and securely.

Uses:

  • Supports door structure

  • Provides a base for Hinges and lock systems

Benefits:

  • Made from durable materials like wood, steel, or composite

  • Essential for maintaining energy efficiency by reducing drafts

Considerations:
Frames and jambs must be installed securely to ensure the door operates smoothly. Frames can warp over time if exposed to moisture, so proper Weatherproofing is crucial.

2. Weatherstripping

Weatherstripping helps seal gaps between the door and the Frame, preventing drafts, moisture, and pests from entering the home. It is critical for energy efficiency and insulation.

Uses:

  • Seals the door to prevent drafts and moisture intrusion

  • Enhances energy efficiency

Benefits:

  • Reduces heating and cooling costs

  • Easy to install and replace

  • Available in foam, rubber, or felt

Considerations:
Weatherstripping wears out over time and may need replacement, especially in high-traffic areas or homes exposed to extreme weather.

3. Thresholds and Door Sweeps

Thresholds and door sweeps seal the gap between the bottom of the door and the floor. This is important for preventing drafts, water infiltration, and pests.

Uses:

  • Seals the door at the base

  • Improves energy efficiency and weatherproofing

Benefits:

  • Prevents drafts and water from entering the home

  • Available in aluminum, wood, or Vinyl

Considerations:
Door sweeps and thresholds can wear out over time, particularly in high-traffic areas. Regular inspection and replacement may be required to maintain a proper seal.

4. Locks and Deadbolts

Locks and deadbolts are crucial for securing exterior doors. A high-quality Deadbolt adds an extra layer of security and can be paired with modern keyless or Smart Lock options.

Uses:

  • Secures exterior doors

  • Adds protection against forced entry

Benefits:

  • Deadbolts provide superior security

  • Keyless and smart locks offer convenience

  • Can be integrated with home security systems

Considerations:
Deadbolts should be installed with a reinforced Strike Plate for additional security. Smart locks require regular updates and maintenance to ensure they function properly.

5. Glass Inserts

Glass inserts can be added to many types of doors, from traditional front doors to sliding and accordion doors. Decorative, frosted, or energy-efficient glass can enhance the door’s appearance and performance.

Uses:

  • Enhances aesthetics and light entry

  • Adds decorative elements to entry doors

Benefits:

  • Allows natural light to enter

  • Double- or triple-paned glass improves energy efficiency

  • Decorative glass provides privacy without sacrificing style

Considerations:
Glass inserts may reduce the overall insulation of the door if they are not energy-efficient. Laminated or tempered glass can increase security by making the door harder to break.
