Exterior walls and ceilings often require a minimum amount of insulation, however, this is not the case with interior walls.
If you are sensitive to noise, get cold easily, and want to avoid a damp house then you should certainly consider it.
There are many benefits associated with insulating interior walls like sound reduction, a warmer house and therefore lower heating bills, and less moisture in your home.
Here's more on the 3 reasons why you might choose to insulate your interior walls and a look at how you can insulate them...
3 Reasons To Insulate Interior Walls (The Pros of Insulating Interior Walls)
Here are 3 reasons for you to insulate interior walls...
1. Sound Dampening
One of the main reasons why homeowners may choose to insulate their interior walls is to dampen the transfer of sound in between rooms.
For some this can be particularly helpful if some rooms inside your home are noisier than others, potentially causing disruption when you are attempting to enjoy a good night's sleep.
Although insulating a wall doesn’t completely prevent this transfer of sound, it can help to significantly reduce the sound that can be heard.
2. Reduction of heat loss and Improved Energy Efficiency
Another common reason that encourages many to insulate their interior walls is to reduce the amount of heat that is lost through these walls.
Doing so is of course going to reduce the amount of energy that you are using and as a result, you can enjoy reduced costs along with improved energy efficiency.
It is also particularly useful if you have unused rooms inside your home.
Without insulation, these rooms will continue to use unneeded heat, however, insulating will help to prevent the heat from transferring to these rooms.
3. Insulation can help to control moisture levels
Another benefit associated with interior wall insulation is the reduction in moisture levels.
Some rooms are exposed to more moisture than others, for example, those that are used for showering.
If this moisture is neglected it will remain in the walls and this can lead to a build-up of mold. Choosing to insulate these walls can help to avoid this issue.
