The Aspects of Insulating Interior Walls


There are many pros when it comes to insulating interior walls, regardless of what type of insulation you should use. While there are many pros, the cons are few, boiling down to basically the time, money, and hassle spent during the process. But, what are the pros to insulating your interior walls?






The air in your house can become humid, with droplets of moisture hanging heavy in the air. This doesn’t only feel uncomfortable in higher amounts, but it also can cause damage to your home. Humidity can sometimes accumulate inside the wall. This accumulation may result in fungus, mildew, leakages, and more. One these issues occur, your home’s very structure is at risk, and you’ll have to hire professionals to come out and remediate the issues.


When you have proper insulation, your home is less likely to swing wildly with humidity and temperature. A well-insulated home will have better temperature and humidity regulation, remaining at safe levels year-round. Insulating interior walls within your home may have a bigger impact than you’d think. 




If you live in an area that has differing seasons and weather, you may find that the temperature inside your home is affected by the outdoors. While this is true anywhere, those who live where temperatures reach extremes will notice this shift more. When your home is properly insulated, you’ll find that the temperature remains more stable.

This means that your heating and cooling systems won’t have to work as hard or as long to remain at consistent temps, saving electricity, making it energy efficient, and lowering energy costs. A stable temperature can also help reduce damage to your home caused by temperature shifts. Insulating interior walls helps to regulate temperatures greatly, keeping your home comfortable all year round. 





Insulation hinders sound waves, especially high-frequency waves, lowering the amount of sound that travels from one wall to another. Insulating interior walls are beneficial if you have a big lively family, or even if you just value your privacy. It will provide everyone with a peaceful private environment away from all hustle and bustle. Your neighbors may also appreciate it if your home is well-insulated, as noise can travel outwards just as easily. Insulating interior walls is exceptional for noise reduction. 



Insulation can add an extra layer of fire protection. However, the insulation used must be fire-retardant to provide any extra protection. For this purpose, it’s also best to use fire-resistant drywall, which increases the wall’s fire rating to a minimum of 1 hour, which is up from the 30-minute rating that you’ll get with the standard ½ inch drywall.



Choosing the right insulation matters, and there are many different types. For example, if you’re looking for sound-deadening purposes, fiberglass, batt insulation, cellulose, spray foam, and rock wool are best. Fiberglass is the most DIY-friendly but does require the wall studs to be exposed for installation.

Cellulose is the least invasive approach to insulating pre-existing walls. While it’s recommended that you hire a professional to help when insulating interior walls, you’ll still want to consider the following when choosing which insulation works best for you:


Is it of good value?

Does it have a good lifespan?

Does it have good thermal resistance?

Is it fire-retardant?

Is the material overall safe for your health?


There are many valuable reasons as to why you should insulate both your interior and exterior walls. You’ll protect your home, make it safer, and more comfortable. You’ll also likely save money on heating and cooling costs, among many other reasons.

While there are plenty of valid reasons as to why you should look into insulating interior walls in your home, there are also a few reasons as to why you may avoid it, such as:




A significant factor that makes people prefer not to bother with insulating interior walls is the possible disruption and damage that it could cause. Depending on the type used, insulation may disrupt your home greatly, for this reason, many avoid insulating the interior of their home.




Insulation inside walls could make repairs slightly more complicated. This is due to the fact that there will be more to work around within the wall. However, any professional should be able to navigate this quite easily.




Insulating interior walls takes time, and while it’s possible to do it yourself, you may find that it’s easier to hire a team of professionals to do it for you. Many people put off insulating their interior walls due to the fact it will take time and is a bit of a hassle. By hiring professionals, you’ll cut the hassle and the time spent significantly.


When you insulate your walls, you’re protecting your home both on the outside and the inside. Insulation regulates temperatures, reduces noise, and reduces fire risk. Your home will be more comfortable and safer when the interior walls are insulated. While doing so may cost time and money, it’s often a worthwhile investment that has the potential to increase the longevity of your home greatly.
