How to Tackle Groin Ceiling Framing

The first steps to take when installing groin ceiling framing

Before you actually start the installation process, you’ve got to frame out your groin ceiling. You’ll do this with materials that meet your local coding requirements, of course. Groin ceiling framing is actually rather simple.

It can be done in just a few easy steps. Then, once you’re done with the groin ceiling framing, it’s time to install. Here is a quick overview of the process to get you started:

  1. You just need to frame a cross brace (two pieces of wood that intersect in the center of your desired location). Just make sure your cross brace is strong enough to support the weight of the groin vault and back bracing. You’ve now completed the foundation for your groin ceiling framing.
  2. Snap two lines to the underside of your or cross brace. Just make sure they’re centered in the groin vault area within ¼”.
  3. Identify and organize your struts. Don’t worry; each one comes labeled with positioning indicators that will tell you exactly where they go. When you see struts marked with an “S,” you’ll know that those belong on the shorter side. Go ahead and separate those from the ones that are marked with an “L.” Those belong on the longer side. Each will also be marked with a number. The number indicates exactly where those struts should be placed within the groin ceiling framing.
  4. Use a square to mark the underside of your existing pieces of the cross brace according to the strut positioning measurements on the groin vault plan that came with your kit.
  5. Now it’s time to place your struts. Start from the outside of the groin vault framing. They may seem short, but don’t despair. They’re made in halves. Line up the squared end of each half to the center mark that you marked in step four. Take a look at the groin vault plan to find the rise and placement of the angle-cut tips. Place your struts and then double check to be sure they are on the correct side and position.
  6. Continue nailing all struts into place until all the outer strut halves are in place. Then, it’s time to work your way inward and follow the steps on your instruction guide to complete the installation.
Although groin ceiling framing looks like it might be complicated, it’s really quite simple. Our prefabricated kits and easy-to-follow instructions take the guesswork out of the process. As you can see from the steps above, you don’t need any fancy tools or showy techniques. All you need is a measuring tape, a nail gun and a little initiative. Your groin ceiling framing will be up in no time.
