Different Ways to Install Roof Truss Ceiling Corner Backing
How to Install Roof Truss Ceiling Corner Backing
Installing roof truss ceiling corner backing is an important step in the construction process. It helps to support the ceiling and prevent it from sagging. There are a few different ways to install roof truss ceiling corner backing, and the best method for you will depend on your specific needs.
Why the Ceiling Backing Needs to Float
The video explains that the truss ceiling backing needs to hang or float and it cannot be touching any of the top plates. The reason for this is because the trusses will settle as more weight is added to them. This settlement can cause the gaps between the ceiling and the wall to become narrower. If the ceiling backing is nailed to the top plates, it will prevent the trusses from settling properly and could lead to structural problems.
Different Methods for Installing Roof Truss Ceiling Corner Backing
There are four main methods for installing roof truss ceiling corner backing that are explained in the video:
The first method is to use a 2x4 framing plate on the end and a 1x4 framing plate running perpendicular to the trusses. This method is the most common and is considered to be safe by most home builders.
The second method is to block the corners of the ceiling backing. This method is easier to insulate than the first method.
The third method is to put a block at the end of the ceiling backing instead of having it sitting on top of the trusses. This method is said to be a better way to prevent the nails from being pulled out of the backing.
The fourth method is to cantilever a 2x4 past the corner and then nail the ceiling backing to it. This method is useful if there are heating ducts or other obstacles in the way.
Bonus Tips
The corner backing can be extended a few inches past the corner for more support.
You can eliminate the board that hangs off of the trusses and attach the ceiling backing to the wall framing instead.
The 1x4 backing that runs parallel to the walls can be difficult to insulate. Blocking between the backings can make it easier to insulate this area.
Additional Tips
It is important to use the correct size lumber for the ceiling backing. The size of the lumber will depend on the span of the ceiling and the weight that it will need to support.
You should also use the correct type of nails or screws to attach the ceiling backing to the wall framing. Screws are generally considered to be more effective than nails.
Be sure to follow all local building codes when installing roof truss ceiling corner backing.
Conclusion
Installing roof truss ceiling corner backing is an important step in the construction process. By following the tips in this article, you can be sure that your ceiling is properly supported and will not sag.
