While we may not think much about the doors we use every day, they’re among the most versatile elements in our homes. From exterior entryways to interior passages, doors come in various types, materials, and styles to suit different needs and preferences.
Your home’s interior and exterior doors do more than keep you safe — they also boost your home’s curb appeal, keep out noise, and give you privacy. In this guide, learn more about residential doors and which ones may be the best fit for your home’s needs.
Types of Doors in Every Home
Doors can be broadly categorized into three main types: exterior, interior, and specialty doors. Each type serves a specific purpose and is designed to meet different needs.
Exterior Doors
Exterior doors are the first line of defense for your home, providing security and protection from the elements and intruders. These doors are typically thicker and more robust than interior doors, usually measuring between 1 ¾ inches and 2 ¼ inches in thickness. They’re designed to withstand harsh weather conditions and provide greater security.
Exterior doors often come in standard widths of 30, 32, or 36 inches, with a standard height of 80 inches. Many exterior doors feature weatherstripping and special sills to keep out rain and wind. For added visual appeal and natural light, some exterior doors are flanked by sidelights — smaller, stationary panels with glass windows.
Interior Doors
Interior doors are generally thinner than exterior doors, with a standard thickness of 1 ⅜ inches. These doors come in several styles and materials to complement different room designs and functions. Standard interior door widths range from 24 to 36 inches, with custom sizes available for unique spaces.
Some interior doors are made entirely of wood, with pine, poplar, and alder being popular choices for painted doors. If you’re looking for a more budget-friendly option, hollow-core doors are another great choice. These doors feature lightweight cardboard honeycomb cores surrounded by wood or medium-density fibreboard (MDF) frames.
Specialty Doors
Specialty doors are designed for specific purposes, like architectural features. Some examples include the following:
- Sliding glass doors for patios or decks
- Pocket doors that slide into wall cavities
- Barn doors that slide along exposed tracks
- Bifold doors for closets or room dividers
These specialty doors offer creative solutions for space-saving or improved accessibility in various areas of the home.
Door Materials: Choosing the Right Option
The material you choose for your door can significantly impact its durability, maintenance requirements, and overall appearance. Wood, steel, fiberglass, and glass are the most common door materials.
Wood Doors
Wood is the traditional material for doors and remains a popular choice for both exterior and interior applications. Wood material doors offer a classic, warm appearance and can be easily customized with different finishes and styles. However, they require regular maintenance to prevent warping and weathering, especially for exterior use.
Steel Doors
Steel is a popular choice for exterior doors due to its strength, security, and low maintenance requirements. Many steel doors feature a wooden interior frame faced with galvanized steel, with the space between filled with rigid foam insulation. This construction provides better insulation than traditional wood doors.
Fiberglass Doors
Fiberglass entry and interior doors have gained popularity in recent years due to their durability, energy efficiency, and low maintenance needs. Like steel doors, fiberglass doors often have a wooden frame with a fiberglass skin and foam core. They can be designed to mimic the look of wood grain and are available in a wide range of styles and colors.
Glass Doors
Glass doors, such as sliding patio doors or French doors, are excellent for bringing natural light into a space and creating a seamless transition between indoor and outdoor areas. All glass used in or near doors is required by code to be safety glass to minimize the risk of injury should the glass break.
Door Styles and Designs
Different door styles and designs can change the overall look and feel of your home. Here are some popular options.
Traditional Panel Doors
Panel doors are a classic choice for both exterior and interior applications. These doors typically feature four or six panels, with vertical members called stiles and horizontal members called rails. The panel construction allows for natural wood expansion and contraction without affecting the door’s overall dimensions.
Modern Flush Doors
Flush doors have a smooth, flat surface without panels or decorative elements. They offer a clean, contemporary look and are often used in modern or minimalist interior designs. Flush doors can be made from various materials, including wood veneers, MDF, or engineered wood.
French Doors
French doors consist of multiple glass panes set within a frame. They’re often used as exterior doors leading to patios or balconies or interior doors between rooms. They allow for ample natural light and create an open, airy feel in a space.
Barn Doors
Barn doors have become increasingly popular recently for interior applications. These doors slide along an exposed track mounted above the doorway, adding a rustic or industrial touch to the room’s decor. Barn doors are also excellent space-saving solutions.
Understanding Door Construction
A door’s construction affects its performance, durability, and appearance. Here are the different ways that doors can be built.
Frame-and-Panel Design
The frame-and-panel design is a traditional method used in many wood doors. This construction technique allows for natural wood movement due to changes in humidity without affecting the door’s overall dimensions. The panels fit loosely in grooves (dadoes) within the rails and stiles, allowing them to expand and contract seasonally.
Hollow Core vs. Solid Core
Interior doors often have hollow-core or solid-core constructions. Hollow-core doors are affordable but provide minimal sound insulation. Solid-core doors have a particle board or engineered wood core, making them heavier and more similar to solid-wood doors. They offer better sound insulation and a more substantial feel than hollow-core doors.
Door Skins and Veneers
Door skins are the outer layers of a door, which can be made from various materials such as wood veneer, MDF, or engineered wood products. For flush doors, these skins can be thin hardwood plywood or MDF. In paneled doors, the skins may be molded to create a traditional panel design.
Door Sizes and Measurements
You need to measure your door openings properly before replacing or installing doors in your home.
Standard and Custom Door Dimensions
Standard door heights are typically 80 inches, while widths vary depending on the door’s location and purpose. Doors wider than 36 inches are usually either custom-made or a combination of two doors.
Custom door sizes are available for unique openings or specific architectural requirements. These doors are made to order and can be tailored to fit non-standard openings or meet specific design preferences.
Measuring for a New Door
Measure the width at the top, middle, and bottom of the door, as well as the height on both sides and in the center. Use the smallest measurements to ensure a proper fit. For pre-hung doors, measure the rough opening, which is typically about 2 inches wider and 2 ½ inches taller than the door itself.
Door Installation and Maintenance
Proper installation and regular maintenance are key to ensuring your doors function correctly and last for years to come. Doors with poor placement or upkeep may begin sticking, squeaking, leaking air, and more. Instead, follow this guidance to get the most out of your investment.
DIY Door Installation Tips
For those comfortable with do-it-yourself (DIY) projects, installing a pre-hung door can be a manageable task. Key steps include the following:
- Measuring the rough opening accurately
- Shimming the frame to ensure it’s plumb and level
- Securing the frame to the rough opening
- Installing the door hardware
- Adding weatherstripping and thresholds for exterior doors
Professional Installation Services
For complex installations or if you’re not comfortable with DIY, professional installation services are available. Experienced installers can ensure your door is properly fitted, aligned, and sealed, which is especially important for exterior doors.
Routine Door Maintenance
Regular maintenance can extend the life of your doors and keep them functioning smoothly. Some maintenance tasks include the following:
- Lubricating hinges and locks
- Tightening loose screws
- Adjusting the strike plate if the door isn’t latching properly
- Fixing any doors that stick
- Refinishing wood doors every few years to protect against weathering
Enhancing Energy Efficiency with Doors
Doors play a major role in your home’s energy efficiency. Insulated doors, typically made of steel or fiberglass with a foam core, offer better thermal performance than traditional wood doors. These doors help maintain a comfortable indoor temperature and can reduce energy costs.
Energy-Efficient Glass Options
For doors with glass elements, such as French doors or doors with sidelights, energy-efficient glass options can significantly improve insulation. Look for double-pane or triple-pane glass with low-E coatings and argon gas fills for optimal energy performance.
Weather-sealing Techniques
Proper weather-sealing is crucial for preventing air leaks around doors. This includes the following:
- Installing or replacing weatherstripping around the door frame
- Adding a door sweep to the bottom of the door
- Caulking around the door frame to seal any gaps
Choosing the Right Door for Each Room
Different rooms in your home may require different types of doors. Here are a few words of advice for choosing doors throughout your home.
- Entryways: Entryway doors should prioritize security, energy efficiency, and curb appeal. Steel or fiberglass doors with multi-point locking systems and decorative glass elements can provide a balance of function and style.
- Bedrooms: Bedroom doors often prioritize privacy and sound insulation. Solid core doors or doors with sound-dampening features are good choices for bedrooms.
- Bathrooms: Bathroom doors should provide privacy while also allowing for proper ventilation. Doors with louvered panels or built-in vents can help manage moisture levels in the bathroom.
- Closets: Closet doors come in various styles to suit different spaces and preferences. Options include bifold doors, sliding doors, or French doors, depending on the available space and desired aesthetic.
Our Conclusion
Doors are more than just entryways; they impact the look, security, and privacy of your home. Proper installation and regular maintenance are key to ensuring your doors perform well and last for years to come. With the right choices and care, your doors will not only serve a practical purpose but also contribute to the comfort, style, and value of your home.
