Raise Framing Opening Headers To Make Stronger Arches - Home Building And Remodeling Tips
The video opens with the importance of avoiding breakage at the tips of arches, especially when these arches are intended for exterior applications and will be covered in stucco. A broken arch tip on an exterior wall can lead to problems, whereas the same issue on an interior wall may be less concerning.
The simplest solution to this problem is to raise the header, which creates a wider arch. While this may seem like an obvious solution, Greg acknowledges that planning ahead and making adjustments can be difficult. He assures viewers that he creates these videos because he has made these mistakes himself, and wants to help others avoid them.
Raising the header all the way to the top eliminates the need for small two-by-fours, which are prone to breaking when nailed into place. A wider header also provides additional stability.
However, Greg points out that the tips of the arch on the lower portion can also break, especially if the arch has a lower slope or a smaller opening with a larger diameter circle. To prevent this from happening, he suggests reshaping this section to be one and a half inches wide instead of coming to a point. This will provide more stability. It is also important to ensure that the trimmer (a horizontal structural member that strengthens the opening above a window or door) is solid and continues up to meet the header, providing structural support.
Greg acknowledges that some engineers may not approve of this alteration, depending on the weight the header will be supporting. In such cases, it is important to consult with an engineer to determine the best course of action, as they may have specific requirements regarding the integrity of the trimmer.
In summary, this short video provides valuable tips for constructing stronger and more durable arches. By raising the header, reshaping the lower portion of the arch, and ensuring a solid connection with the trimmer, viewers can avoid common mistakes and create beautiful, long-lasting arches. It is important to note that consulting with a qualified engineer is always advisable for projects involving significant structural changes. Back To Arch Framing
