How To Flatten Vaulted Ceiling - Pressure Blocking and Joist Hangers Part Three
In this part, we will discuss two methods for attaching the ceiling joists to a ledger: pressure blocking and joist hangers.
Pressure Blocking
Pressure blocking is a simple and effective method for attaching ceiling joists to a ledger. It is typically used for ceilings that are less than 8 feet wide and will not be carrying a structural load.
To use pressure blocking, first nail a ledger to the walls. The ledger should be level and parallel to the floor joists. Next, place pressure blocks in between the ceiling joists. You can place a block in every bay between each joist, or you can simply toenail the ceiling joist to the ledger.
Pressure blocks are typically made of wood or metal. Wood blocks are more affordable, but metal blocks are more durable.
Joist Hangers
Joist hangers are another option for attaching ceiling joists to a ledger. This method is typically used for ceilings wider than 8 feet. Joist hangers are also a good option for ceilings that will be carrying a structural load, such as a second floor or a roof.
To use joist hangers, first nail a ledger to the walls. The ledger should be level and parallel to the floor joists. Next, place the joist hangers on the ledger. The joist hangers should be positioned so that they straddle the ceiling joists. Finally, nail or screw the joist hangers to the ledger.
Joist hangers are available in a variety of sizes and styles. The size of the joist hanger you need will depend on the size of your ceiling joists.
Choosing a Method
The best method for attaching your ceiling joists to a ledger will depend on the size of your ceiling, the weight of the ceiling joists, and the structural load that the ceiling will be carrying. If you are unsure which method to use, it is a good idea to consult with a structural engineer.
Additional Tips
Make sure that the ledger is level and parallel to the floor joists.
Use the correct size and type of pressure blocks or joist hangers.
Nail or screw the pressure blocks or joist hangers securely to the ledger.
Shim the ledger if necessary to level it.
Inspect the ceiling joists for any damage before flattening the ceiling.
Repair any damage to the ceiling joists before flattening the ceiling.
Hire a professional contractor to help you with the project if you are not comfortable doing it yourself.
