Benefits Of Insulating Interior Walls

Insulation is an excellent approach to increasing your home’s overall livability, efficiency, and utility. The advantages of insulation are various, and they are mostly dependent on the type of insulation you intend to install on your interior walls.

Interior insulation can also improve the seclusion of spaces such as bathrooms. If your house has thin walls or you have a boisterous population, insulating inside walls is a terrific idea. Insulation has the advantage of delivering all of these benefits while also being simple to install.

However, not all insulation is created equal.

Energy Efficiency

Insulation for inside walls works similarly to insulation for outer walls. It slows the flow of heat from one room to the next. Outside air will easily enter your home without internal insulation, causing the temperature of your rooms to fluctuate to uncomfortable levels.

Temperature changes will make your HVAC unit work more to bring your home to the set temperature, raising your utility cost. The temperature changes in each room of your home will be reduced with interior insulation.

Better Resistance Against Cold

If you live in a cold climate, insulation is a must-have. Insulation keeps your utilities safe and allows them to work even in cold weather. Lofts and foundations are typically insulated for cold resistance.

Fire-Resistant

When a fire breaks out in your house, the speed it spreads might be the difference between life and death for you and your family. The spread of flames is slowed by fire-resistant wall insulation, which keeps the fire limited to a smaller area, giving you more time to flee.

It also guards against more serious damage to your home and possessions. Despite this, insulating systems constructed from these materials can attain a fire rating of about average. The safer option is loose-fill. Paper, which burns easily and spreads flames, is frequently found on batts.

Moisture Control

Regular activities such as cooking, cleaning and showering produce moisture in your home. Mold, rot, mildew, and water stains might result if this moisture condenses in your walls. Mold and mildew are dangerous to your family’s health.

Moisture gathering can be reduced by insulating your internal walls. Vapor-resistant membranes can be applied to your insulation to keep condensation at bay. You can assist control this moisture by choosing an insulating solution with a vapor barrier. This will assist prevent the growth of harmful mold and mildew in your walls.

Increase Your Property Value

Party walls, or interior walls that divide individual living spaces into duplexes or flats, are typically insulated to reduce sound and thermal transfer and prevent fire from spreading from one side of the wall to the other.

The insulation and the drywall, tape, and compound used to build the wall must all be fire-rated in this situation. Check with your local building authority before erecting or changing a party wall.

A permit may be required, and a code enforcement officer will inspect the wall to ensure that it meets fire code requirements.

The Common Types Of Insulation

When it comes to insulating your interior walls, there are various options to consider. Let’s look at some of the more common and less common types of insulation.

Cellulose

Cellulose insulation is created from plant-based fibers and is perhaps the oldest insulator available. When someone talks about cellulose insulation nowadays, they usually refer to a type of insulation manufactured from recycled newsprint.

The paper is finely ground, the dust is removed, and a fire retardant is added. The remaining fibers can be blown in either loosely or densely. Because loose-fill might settle and leave gaps in your insulation, dense packing is ideal.

Fibreglass

Fiberglass is a lightweight material that is simple to install. You can buy it in the form of batts or rolls or have it blown into your walls. Fiberglass is a common insulation solution due to its low cost. Some folks, however, are concerned about the formaldehyde used in the procedure and the long-term health dangers that come with having it in the house.

Polystyrene

Polystyrene, or Styrofoam, is a good insulator. Because of the increased R-value, less insulation is required. It is delivered in rigid boards, making installation a breeze. While polystyrene may not appear to be very environmentally friendly at first look, the energy savings can help you lower your carbon footprint significantly.

Mineral Wool

Mineral wool is not to be confused with sheep’s wool. Industrial slag or basalt is used to make mineral wool. The materials are heated to a molten state and then spun into fibers, similar to fiberglass.

The R-value and installation process are comparable to fiberglass. Mineral wool is available in batts and rolls as well.

Final Thoughts

There are numerous reasons to insulate the inside walls of your home. While your minimal local criteria may not need inside insulation, no one wants to live in a home that only meets the bare minimum. Interior wall insulation makes your home more comfortable and safer by regulating temperatures, minimizing noise, and lowering your fire risk.

The majority of common insulation materials perform well in interior walls, but learning about the benefits and drawbacks of each can help you choose the one that best suits your needs.
