A better understanding of the basement insulation processes will help you to approach the question of your foundation’s waterproofing and heat preservation in a more professional and knowledgeable way. On this page, we are going to talk about basement insulation in detail and will explain why it may be an important step to take.
Approximately 20% of a house’s heat loss stems from the foundations. Those areas of our homes are frequently not isolated, suffer from excess moisture and water, and feature various cracks and leaks. The basement is a sort of a separator between your home’s living space and the cold soil. Therefore, it is quite logical that this is the coldest space in our houses.

As a result, you have to pay more money for the utilities to make your foundation warmer. This money is spent in vain, as the basement will be cold and wet until the proper actions are taken. The best way to waterproof your basement and preserve the heat is to choose one of the available basement insulation methods.
Basement Floor Insulation
Your foundation insulation could be approached both as a set of complex measures and individual solutions for its certain parts. The final choice would depend on your budget as well as the problems identified in your basement. Sometimes, you might consider insulating your floor separately.
Why Is Basement Floor Insulation Important?

While insulating your basement floors might not be as effective as insulating the walls, it is still an important step to take. There are three main components contributing to the importance of basement floor insulation.
- Heat loss prevention
- Excess moisture protection
- Comfort and a neat look

What Are Floor Insulation Options?
There are a few options for basement cold room insulation that you can choose from. Your final choice will depend on certain factors, in particular the height of your basement space.
Ceiling Height Is Not A Problem
If you are not concerned about the height of your basement walls and have enough space in your basement, you are lucky. The best way to insulate the floor is to place a polyethylene sheet over the concrete floor. This layer will serve as a vapor barrier – one of the most effective waterproofing products. A layer of rigid foam insulation is applied over it. The method is reliable and safe; however, it will take up to three inches of your basement’s height.
Ceiling Height Is Not Enough
If you cannot afford to allocate three inches of your basement floor space height for insulation, there is another solution for you. Special subfloor systems consist of rigid foam insulation combined with a compact vapor barrier and a subfloor material. This product comes in a compact panel that still does its insulation job while being much lower than the original insulation set.
If you are not sure what method to choose, consult with your waterproofing company. We will be happy to assist you with this at No Water System Experts.
Basement Ceiling Insulation
The insulation of the basement ceiling is as important as the one on the floor. Of course, if you insulate the floors, the ceiling insulation might not be necessary. If you still decide to perform it, you might be interested in the types of ceiling insulation available in the market.
Blanket Insulation
The “blankets” are made of fiberglass, mineral wool, and cotton or cellulose. Those materials come in batts and rolls, which your contractor will attach to the ceiling. This is by far the most popular and traditional way to insulate your foundation.
Paper-facing Insulation
Another alternative to insulating your basement is peeling off the special paper around the edges and using it to fill in the joists in your ceiling. This type of insulation is not perfect. If you experience moisture issues in your basement, we do not recommend using paper-facing insulation. Instead of protecting your basement from moisture, the paper may accumulate and become a great environment for mold.
Spray Foam Insulation
Spray foam insulation for the basement ceiling might be the best solution for your foundation. It does a great job insulating the basement, preserving the heat, and protecting the house from excess moisture. At the same time, it is simple and quick.
