How To Construct An External Door Header?

This tutorial focuses on the process of building a framed rough opening and provides guidance on various framing techniques. Window headers are beams that provide structural support across open spans in window framing, allowing openings for windows without weakening a wall. To build a load-bearing header, measure the span of the opening in feet and add 2 to that number. The header is built by superimposing 2 pieces of lumber.

For a box header, a structural panel is installed on the outside face of the framing (for a one-sided box header) or on the inside and outside faces (for a two-sided box header). The tutorial covers the entire framing process for an exterior door, including cutting through drywall, assembling new studs, and building a new door frame.

To add thick Craftsman and farmhouse door trim to windows and doors, measure twice, cut once, and look at the nail, not the hammer, and watch the fence, not the blade. Modifying the exterior door header requires careful planning and organization, as well as careful attention to detail and safety.

How to put a header on a door frame?

To create a header, fit two 2 x 8s around a 1/2-inch piece of plywood, secure them with construction adhesive and nails. Cut the header to fit between the king studs and install a cripple stud halfway between the studs. Toenail the cripple stud to the top plate and the side of the header. Ensure the horizontal stud faces are co-planer with the king and jack studs’ edges. Position the jack studs against the inside of the king studs and nail them into place. Use a hammer or nailer to nail through the king studs into the header. Co-planer joints are crucial to prevent uneven drywall and doorcase trim gaps.

Do exterior doors need headers?

Exterior walls are load-bearing, requiring doubled studs on both sides of the door opening and a larger header than interior doors. Local building codes provide minimum header sizes based on rough opening size. Use a level to create guidelines for the rough opening, ensuring it is square, level, and plumb. Draw additional lines 1-1 ½” outside of these lines to account for drywall removal. Consider the space around the exterior door frame, stairway or stepping support needed, and the type of flooring on the interior.

If carpeting is used, add an appropriate amount to the doorjamb height to allow clearance between the carpet and door. Additionally, consider the type of stairway or stepping support needed for accessing the door from the exterior.

Why put plywood between headers?

Structural engineer Christopher DeBlois emphasizes the importance of plywood thickness in header designs. However, he argues that the additional strength from plywood is often overlooked due to several reasons. The thickness of plywood is only added when the grain is horizontally parallel to the direction of the header. This extra thickness is only effective if there are no splices in the plywood near the middle of the span, which is not often the case for headers at openings wider than 8 feet.

Additionally, size limitations make the plywood almost never make a critical difference in safety. When designing a header, the number may suggest two 2x9s, but two 2x9s are about 30 stronger than two 2x8s. Therefore, the 2x8s plus 8 from 1/2 inch plywood would not be strong enough. DeBlois suggests using double 2x10s for all headers, big and small, as headers only come in certain depths. The extra strength in the 2x10s means that the small extra strength from the plywood is rarely important.

Can you install a door without a header?

The header board is a crucial component in the barn door system, providing stability and strength to the door, ensuring smooth and secure operation. It prevents the door from resting solely on the frame, preventing structural damage and compromising its functionality. The header board also serves as a mounting surface for the track, providing a secure and level base for the door, especially for heavier doors. This ensures smooth operation without strain on the track or door frame.

Using a header board in barn door installation enhances the door’s stability and durability, preventing sagging or warping. It also simplifies the installation process by providing a level and secure surface for attaching the track, eliminating the need for complicated adjustments or modifications to the door frame. This makes the installation process quicker and more efficient, saving time and effort.

How thick should a door header be?

A 2-inch piece of lumber has a thickness of 1. 5 inches. Therefore, to obtain the desired result of 3. 5 inches, it is necessary to multiply the piece of lumber by 2 and add 0. 5 inches. In order to construct a door header measuring 4 inches by 4 inches for a door measuring 4 feet in length, the lumber must be cut to a length of 4 feet or 48 inches plus 3 inches, in order to accommodate the thickness of the jack studs that are supporting the door header.

What lumber to use for door header?

Double 2×12 headers are the standard for window and door openings, but alternative designs like rim-board header, box header, and using a flat 2x are available. The standard header for most window and door openings was a double 2×12 with a 1⁄2-in. plywood spacer to bring it flush with the stud edges in a 2×4 wall. When pushed hard to the double top plate of an 8-ft.-high wall, its bottom sets up window and door head jambs 6 ft. 10 in. off the floor, perfect for standard 6-ft. 8-in. doors.

When high-performance homes gained market share in the late 1980s, the building industry looked for ways to reduce the amount of lumber used to build headers or eliminate conventional headers altogether. Double 2×12 headers are often oversize for the load, but there is no structural advantage to installing larger headers. They also have downsides, such as higher costs and increased risk of drywall cracks due to green lumber dries or dried lumber expansion during seasonal humidity changes.

What type of wood is used for headers?

Headers are crucial structural elements in house framing, supporting the weight of loads above openings like doors and windows. Two common options for headers are Laminated Veneer Lumber (LVL) and traditional 2×12 lumber. LVLs are engineered wood products made by laminating thin veneers with adhesives, resulting in a strong and durable material with high load-bearing capacity. They are also known for their consistency and uniformity, minimizing the risk of warping, twisting, and other issues associated with traditional lumber. Making an informed decision on header materials can lead to cost and time savings.

What is the typical header size for an exterior door?

A typical header width with single jack studs is 3 inches larger than the rough opening, such as a 36″ door with a 38″ rough opening width. Double or triple jack studs may be required based on the opening width and load the header carries. Before framing, check code requirements. Headers are similar to small bridges, allowing loads to cross without plunging into the water below. Load bearing, non-load bearing, span, and load are all terms used to describe and calculate door and window header sizes. Breaking down headers into simple descriptive terms is essential for accurate framing.

How is a header constructed?

Headers are wood members that transfer loads above openings, creating openings for windows, doors, and interior passageways. They serve a structural purpose by collecting and redistributing the weight of above openings to adjacent studs. The depth of the header is determined by the weight from the structure above and the width of the opening. Grademarks identify species, grade, grading agency, and mill number, allowing traceability to the mill of origin and establishing structural properties. Most 2×4 dimension lumber is visually graded and marked with an ink stamp at the mill, ensuring the product’s strength for the application.

What is used to support a door header?

Jack studs are a necessary component in the support of a header within a wall opening, regardless of whether the wall is load-bearing. These studs are exclusively found on King studs with a nailed “header.”
