Door Header Non Load Bearing Wall: A Comprehensive Guide

Understanding Door Headers in Non-Load Bearing Walls

A door header is a structural element installed above a doorway to support the weight of the wall and any loads above it, while maintaining the opening for the door. In non-load bearing walls, the header carries the weight of the wall above the door, but not the weight of the roof or other structural elements.

Types of Door Headers for Non-Load Bearing Walls

1. Single Header:
- Consists of a single beam spanning the width of the door opening.
- Suitable for small openings (less than 4 feet wide) and low loads.

2. Double Header:
- Comprises two beams placed side by side, with a spacer between them to create an opening for utilities.
- More suitable for wider openings (over 4 feet wide) and heavier loads.

3. Triple Header:
- Similar to a double header, but with three beams to support larger openings and heavier loads.

4. Box Header:
- Forms a box-like structure around the opening, providing additional strength and stability.
- Ideal for very large openings or high-traffic areas.

Material Options for Door Headers

• Wood: Economical and easy to work with, but has limited load-bearing capacity and can warp over time.
• Steel: Strong and durable, capable of supporting heavy loads, but more expensive than wood.
• Engineered Lumber: Combines the strength of steel with the affordability of wood, providing a balance between strength and cost.

Sizing and Load Calculations

The size and type of door header required depends on the size of the opening, the weight of the wall, and the expected loads.

• Opening Size: Measured as the width and height of the doorway.
• Wall Weight: Determined based on the type of wall construction and materials.
• Load: Includes any dead loads (permanent fixtures like shelves) and live loads (occupancy or equipment).

Installation Process

1. Mark the Header Location: Determine the height and position of the header using a level and framing square.

2. Cut the Header: Measure and cut the header beams to the required length and configuration.

3. Support the Existing Wall: Install temporary supports under the wall above the doorway to prevent it from sagging during installation.

4. Insert the Header: Carefully lift the header into place and secure it to the studs using framing anchors or bolts.

5. Support the Header: Install joist hangers or blocking above the header to distribute the load.

6. Finish the Opening: Install the door frame and trim to complete the doorway.

Engaging Stories

Story 1:
A homeowner decided to install a new door in a non-load bearing wall but neglected to use a header. As a result, the wall above the doorway began to sag, damaging the drywall and door frame. The homeowner had to hire a contractor to install a header and repair the damaged wall, incurring significant costs.

Lesson Learned: Never underestimate the importance of a door header. It provides essential support to the wall and prevents structural damage.

Story 2:
A handyman attempted to install a door header in a non-load bearing wall using wood that was too thin and weak for the load. The header sagged under the weight of the wall, causing the doorway to become misaligned and difficult to open. The handyman had to remove the faulty header and replace it with a stronger one, delaying his progress and frustrating the customer.

Lesson Learned: Use the correct type and size of header for the job. Don't sacrifice strength for convenience or cost.
