One of the most intimidating aspects of our renovation was the initial demolition. We modified our floor plan in only small ways, but we still had to tear out all of the drywall in our kitchen and modify a few of the studs. If you have limited experience with construction, most of this will sound foreign to you. I hope this post can help you understand the very basics of an interior wall. We will get into more detail in later posts.
An interior wall is comprised of two primary parts: the exterior shell
and the interior support
. The exterior shell is generally drywall in newer construction, but can be anything from wood planking to extremely thick plaster. For now we will assume that you have drywall in your house. The interior supports are generally constructed from wood 2x4s that are nailed together to form what we call wall studs, but they can also be constructed of metal. Further information below:
The exterior shell of a wall is most often made of drywall
. Drywall is a basically gypsum plaster (a type of cement) formed between two massive sheets of paper. Most drywall comes in 4′ x 8′ sheets. I will be writing a post on concrete in the future, but for now you should be aware that gypsum plaster is not very strong, especially when it comes to tension. Once you cut the paper on the outside of the drywall, it can be fairly easy to split it in half with your own hands. There are multiple ways to finish drywall. If you are starting demolition, be aware that there could be another coat of plaster covering the drywall, and this will often fall off in pieces.
The interior support of an interior wall is made from 2x4s, often pine but sometimes made of metal. The top and bottom of the wall supports are comprised of the Top Plate
and the Bottom
or Sole Plate
. The Wall Studs
are made from 2x4s that span the area between the top and bottom plates. Wall studs are often placed 16 inches apart (from center of stud to center of stud), but the distance can vary depending on the length of the wall and what is going to be between the walls. The purpose of the wall studs is to provide support for the drywall. The last parts of a basic interior wall are the fire blocks
. These are 2x4s that span between the wall studs around 4′ from the ground. These prevent any fire that may start in the bottom of a wall from rising up.
One thing to be aware of are the other elements that you will find within a wall. According to companies like https://home-proelectric.com/cambridge-electrical-panel-upgrades/
, electrical wiring and plumbing are between the wall studs in existing construction and you want to be sure you know what is behind any drywall before you tear into it, I’d recommend getting help from an expert in Furnace Repair in Twin Falls, ID from sites like an Electrical Services business. Remeber that when doing home projects like this one, it’s important to find yourself a home warranty program to protect your investment.
