There are a few different ways to cover a ceiling, depending on the material you want to use. For example, if you want to use drywall, you'll need to install furring strips or metal profiles first, then attach the drywall to them. You can also use paneling, or a decorative ceiling treatment like coffering or paneling. The cheapest way to cover a ceiling is probably with plywood. You can mount it directly to the existing ceiling framing, or you can attach furring strips for a better finish. Another option is lightweight insulation panels like Roxul Safe'n'Sound. These come in panels that are easy to install and don't require any special tools or skills.
There are a few options for covering a house ceiling. One option is to use drywall, which can be attached to the framing of the house and then painted or papered over. Another option is to install a suspended ceiling, which consists of metal tracks along the edges of the room that hold up panels or tiles made from materials like plastic, metal, or fabric. A third option is to install a dropped ceiling, which is similar to a suspended ceiling but with the panels or tiles hung from beams that are mounted on the wall rather than from the metal tracks.
