How To Add Insulation To An Existing Home

If your heating and air conditioning bills is getting out of hand, it’s possible that you may not have enough insulation in your house. Insulating your house is one of the most effective ways to reduce your overall energy costs. Having insulation will maintain your ideal temperature in your home all year round, preserving it from cold in winter and hot temperatures in summer. Usually, insulation is already incorporated into the house while it’s being built. Fortunately, there is a way to add insulation to the walls of existing homes that require it. 

If you’re currently freezing in your house, you should consider hiring a contractor to install insulation–better yet, visit knaufinsulation.com.au. However, before hiring a professional contractor, continue reading this article to get an idea about the installation process. 

 

  • Learn Which Areas Need Insulation

You might be keen to insulate your house, but do you know where to begin? If you’re not sure where to start, these are the key locations to insulate in your house:

  • Attic – The most important place in the home to insulate. This is mostly due to the fact that heat naturally rises, which means that the attic will retain a large portion of the heat produced in the house. 
  • Walls – Since air can escape through walls, it’s better to insulate them as well. Insulating the interior and exterior walls serves as a barrier between the inside and outside of your living area, which eliminates drafts. Another advantage of insulating walls is that it provides privacy by suppressing sounds.
  • Floors – Despite the fact that heat rises, a significant amount of conditioned air can still be lost when they travel through floors. This is relevant for floors over unheated spaces such as garages or basements. Insulated flooring can diminish noise, especially in multi-level homes where occupants dwell on various floors.
  • Ceilings – Because heat rises, your house also loses heat through its ceilings in the wintertime. In the summer, this part of your home will be quite hot. Insulating your ceilings can moderate these thermal swings. Not only that, but insulation also keeps condensation from collecting on ceilings thereby causing moisture-related problems like mold.
  • Basement – This is one area of the house where insulation is neglected most of the time, though it provides significant benefits to a homeowner when insulated. Insulation will produce immediate warmth to this section of your home. Furthermore, insulation protects against moisture, so you won’t have to bother with mold or bugs.

Once you know which areas you’ll be insulating, it’s time to decide which type of insulation you’ll be applying.

  • Decide Which Type Of Insulation You Need For Your House

After you evaluate the areas you’ll be insulating, be familiar with the types of insulation that are usually used so you’ll know what’s best for your home. These include fiberglass, cellulose, mineral wool, and foam. 

  • Fiberglass – This consists of fine glass fibers. Fiberglass is the most common type of insulation because it is naturally resistant to fire. It is installed in between walls, floors, and ceilings. Fiberglass is an excellent choice for those on a budget or who want to DIY since it’s affordable and very easy to install.
  • Cellulose – Composed of paper fiber, these tiny substances work together to produce an insulating material that can be applied to any part of the house without hindering the structure or finish. However, unlike fiberglass, it’s more flammable since it’s made from paper.
  • Mineral Wool – Similar in appearance to fiberglass, mineral wool is a thick, loose-fill insulation. There are two types of wool mineral insulation: one is composed of natural stone fibers like molten basalt or diabase, while the other type is created by spinning slag. Many contractors recommend it since it provides noise insulation and is not flammable.
  • Foam – There are other forms of foam insulation, but spray foam is the most popular one in home insulation. Spray foam is a spray-type insulation ideal for filling openings and gaps. This may include areas around power outlets and fixtures, as well as the spots where the walls, windows, and doors are. Spray foam maintains its form, meaning it will never compress or sag in the long run.

Keep in mind that the best insulation for your house depends on the weather conditions and the structure of your home. Also, it’s possible for different areas of the house to have different types of insulation. 

  • Apply Where It Is Needed

Now that you know which places to insulate and what type of insulation should be used, apply insulation where needed. For example, to add insulation to any external wall, holes must be drilled between the existing wall’s frame. Then, apply spray foam using a spray foam gun, cellulose, or any other type of insulation of your choice into the cracks and crevices to fill them. As you can see, this is a task you would employ a contractor for. Yet, if you have the necessary knowledge and tools, you can do it yourself.

Conclusion

Now that you’re equipped with the knowledge of making your house comfortable and heated through insulation, you’ll be able to enjoy a cozier home all year and your budget will recognize the change as well.
