How To Insulate Basement Walls: The Easy Way
When you think of insulation, fluffy yellow fibreglass rolls are likely to come to mind. Yet despite the widespread belief that this fibrous material provides adequate protection against heat loss, this simply isn’t the case-especially in terms of your basement.
Over time, traditional insulation materials lose their efficacy, with gaps between fibres creating serious cause for concern, not only in terms of your comfort, but also in terms of your costs.
Although basements are mostly utilised for storage, with the addition of adequate insulation, they can be instantly transformed into a habitable room to relax in. Here’s how…
Why Insulate In The First Place?
Moisture and mould are not the only reasons why you need insulation in your basement. There are many reasons that contribute to the fact that you need insulation in the basement.
But first and foremost, your basement is costing you money. You lose a lot of heat through the basement. Adding insulation will provide a great payback and return of investment. To understand how you lose heat, you need to look at the way heat works.
Basically, the second law of thermodynamics says that heat travels from hot areas towards cold, and never the other way around. To put it simply, a cup of coffee will always go cold, and a cup of ice cream will always melt. This second law of thermodynamics is also responsible for higher than average bills.
When your home is not properly insulated, the hot air from inside will travel outside (towards the colder area). There are three forms of heat transfer: conduction, convection, and radiation.
Without going deep into science, the simple answer is that you need insulation to prevent the heat from your home travelling outside.
Or even more importantly, if the basement is not insulated, it will eventually draw energy and heat from your living space, firstly towards the basement, and ultimately, towards the outside.
Insulating the basement will increase the walls longevity. An insulated basement has an optimal energy efficient rating. Installing insulation will lock the expensive and conditioned air and block outdoor temperatures. Without insulation, your basement walls will see a buildup of moisture, and eventually, mould.
Give Moisture Its Marching Orders-For Good!
One of the biggest challenges with how to insulate basement walls is moisture. When it comes to basement walls insulation, moisture is a big problem.
Insulation should and will provide a solution for the moisture problem. However, the mistake you need to avoid is installing insulation on moisture. If you have serious moisture infiltration, your first step towards how to insulate basement walls is to fix the moisture problem. Once you fix the problem, you can apply insulation. Otherwise, the effects would go to waste. But if you hire a professional and certified contractor, the company will warn you about the moisture problems, and help you eliminate before installing insulation.
Basement Insulation: 3 Main Materials
There are three common types of insulation people use for basement walls. Those are mineral fiberglass, wool, or spray foam.
Fibreglass comes in batts that are rolls or blankets made from mineral fibres. Considered one of the cheapest insulation materials, fibreglass comes with its own set of downsides. It is worth considering the disadvantages of fibreglass before opting for it as an insulation material.
Mineral wool is another popular insulation material. But same as fibreglass, it has some disadvantages, mainly that you need a lot of space. Using mineral wool insulation will tighten up your space. And if you are looking for a high impact resistant system, mineral wool is not one.
Spray foam is the third popular material, one that is gaining popularity recently. It can be sprayed into empty cavities to fill the entire space. The best part of spray foam is that you achieve higher R-value with less thickness.
Advantages Of Basement Insulation
There are two ways for how to insulate basement walls. You can use outdoor and indoor insulation. Today, we are talking about interior basement walls insulation, so let’s take a look at some of the benefits of this method of heatproofing:
- Interior basement walls insulation integrates more smoothly with the construction schedule
- You do not need to think how to protect the above-grade portion of the exterior basement insulation
- It is easy to provide uninterrupted connection between the below-slab insulation and the wall insulation
- It can be installed after the building is dried
Final Conclusion: Best Basement Insulation Option Overall
As we hinted previously, spray foam is widely considered to be the best option for how to insulate basement walls not only for the dictates of today, but also the demands of tomorrow.
Spray foam has an expansive nature, and because of its nature, it can cover a large space with less material. Once sprayed, the foam can expand to 100 times its original volume. When you look at the R-value chart, spray foam outperforms all other types of insulation by wide margins.
The expansive nature of the spray foam allows it to create an airtight seal. It is the only insulation material that can fill all cracks and holes in your wall. All other types of insulation always leave something behind.
But with spray foam, sealing cracks is easy. Because of that, spray foam prevents air-leaks-the biggest reason for heat loss.
The air-tight seal of spray foam makes it the most powerful insulator on the market. As such, spray foam can easily provide energy savings in the range of between 30-50%.
Most importantly, when it comes to basement walls, spray foam takes care of one of the biggest problems, and that is moisture. Sealing holes and cracks prevent moisture from entering the home. And because it is composed of an inert polymer, spray foam does not provide a source of food for mould and bacteria.
The big reason for considering spray foam for your basement walls insulation is longevity. Spray foam has an indefinite lifespan. Most companies even offer a guarantee of 20+ years. And during all that time, spray foam will perform at optimal level, without ever sagging or settling.
