1. Types of Interior Doors

Interior doors come in several styles, each serving different purposes:

A. Panel Doors

These are the most common interior doors, featuring raised or flat panels. They can have two to six panels and work well in traditional and modern homes.

B. French Doors

Featuring glass panes, French doors allow natural light to flow between rooms while maintaining an elegant look. They’re ideal for dining rooms, offices, or patios.

C. Pocket Doors

These doors slide into a wall cavity, saving space in small rooms like bathrooms and closets.

D. Barn Doors

A trendy choice, barn doors slide on a track mounted outside the wall, offering a rustic or industrial aesthetic.

E. Bifold Doors

Commonly used for closets, bifold doors fold in half when opened, making them space-efficient.

F. Flush Doors

Simple and smooth, flush doors are affordable and work well in minimalist or contemporary homes.

2. Materials Used in Interior Doors

The material of your interior door affects durability, soundproofing, and appearance.

A. Solid Wood

Pros: Durable, elegant, excellent soundproofing.
Cons: Expensive, can warp in humidity.
Best for: High-end homes, traditional styles.

B. Hollow Core (Composite)

Pros: Lightweight, affordable, easy to install.
Cons: Less durable, poor sound insulation.
Best for: Budget-friendly projects, low-traffic areas.

C. Solid Core (MDF or Particleboard)

Pros: Better soundproofing than hollow core, more stable than solid wood.
Cons: Heavier, moderately priced.
Best for: Bedrooms, offices, noise-sensitive areas.

D. Glass Doors

Pros: Brightens spaces, modern look.
Cons: Less privacy, fragile.
Best for: Offices, kitchens, decorative entries.

E. Metal & Fiberglass

Pros: Extremely durable, fire-resistant.
Cons: Limited styles, higher cost.
Best for: Commercial spaces, modern homes.

3. Styles and Designs

Interior doors come in various designs to match your home’s décor:

Traditional: Raised panel, ornate details.
Modern: Flat panels, sleek lines, minimalistic.
Rustic: Distressed wood, barn-style.
Contemporary: Glass inserts, mixed materials.

Choosing the right style enhances your home’s aesthetic appeal.

4. What Are Prehung Interior Doors?

A prehung interior door comes pre-assembled in a frame (jamb) with hinges already attached. It includes:

The door slab
Hinges (usually 3)
Door jamb (frame)
Door stop molding
Pre-cut strike plate recess

Unlike slab doors (just the door itself), prehung doors simplify installation since the frame is ready to mount.

5. Benefits of Prehung Interior Doors

A. Easier Installation

Since the hinges and frame are pre-attached, installation is faster and requires less skill than hanging a slab door.

B. Better Alignment

Prehung doors ensure proper spacing and alignment, reducing issues like sticking or uneven gaps.

C. Improved Insulation & Soundproofing

The pre-installed weatherstripping in some models helps with noise reduction and energy efficiency.

D. Professional Finish

Prehung doors often come with pre-drilled holes for handles and locks, ensuring a polished look.

E. Ideal for New Construction & Renovations

Whether you’re building a new home or replacing old doors, prehung doors are a convenient choice.

6. Installation Process of Prehung Doors

Installing a prehung door is simpler than a slab door but still requires precision. Here’s a basic guide:

Tools Needed:

Level
Shims
Screwdriver/drill
Hammer & nails
Caulk & paint

Steps:

Remove the Old Door & Frame (if replacing).
Check Rough Opening Size (should be 2″ wider/taller than the door).
Insert the Prehung Door into the opening.
Shim the Frame to ensure it’s level and plumb.
Secure the Frame with screws or nails.
Test the Door Swing to ensure smooth operation.
Install Trim & Finish with caulk and paint.

For best results, follow manufacturer instructions or hire a professional.

7. Choosing the Right Interior Door for Your Home

Consider these factors when selecting an interior door:

Room Function: Bedrooms need privacy (solid core), while closets can use bifold doors.
Home Style: Match the door design to your home’s aesthetic.
Budget: Hollow core doors are affordable; solid wood is premium.
Durability: High-traffic areas need sturdy materials.
Soundproofing: Solid core or solid wood doors block noise better.

8. Maintenance and Care Tips

To keep your interior doors in top condition:

✔ Clean Regularly – Wipe with a damp cloth.
✔ Lubricate Hinges – Prevent squeaking with oil or WD-40.
✔ Check for Warping – Especially in humid climates.
✔ Repaint/Refinish – Refresh the look every few years.
✔ Adjust Striking Plate – If the door doesn’t latch properly.
