If you’re looking for an effective way to keep your home warm during the cold winter months, insulation under your floors is a great option. Not only does it help keep the heat in, but it also helps reduce noise from creaking floors. However, before you purchase any insulation products, there are a few factors that you need to consider.
Firstly, take into account the size of your home and the type of flooring you have. Different types of flooring may require different types of insulation, so it’s important to do your research to ensure that you’re getting the right product for your needs. You should also consider the level of insulation you need, as this will depend on the climate you live in.
Another important factor to consider is the installation process. While some insulation products can be installed by homeowners, others may require the help of a professional. This is especially important if you have never installed insulation before or do not have the necessary tools.
If you’re still unsure whether insulation under your floors is the right choice for your home, ask yourself: Are you tired of cold feet during the winter? Are your energy bills consistently higher than you’d like them to be? Do you want to reduce noise from creaking floors? If you answered yes to any of these questions, then insulation for under floors might be just what you need to keep your home cozy and comfortable all winter long.

1. Ecofoil Heated Floor Insulation – Under Slab Solution.
EcoFoil's reflective foil insulation is the perfect solution for insulating heated floors installed under concrete slabs. Its reflective foil technology prevents heat from escaping into the soil and redirects it upwards where it belongs. This under slab insulation is lightweight, heavy-duty, and easy to handle, making installation quick and easy. It requires no special clothing or breathing equipment.
Without under slab insulation, heat will escape into the soil, reducing the effectiveness of your heated floor unit and making it more expensive. The thermal insulation reduces heat loss by 57% and provides a vapor and radon barrier, making it an ideal solution for your heated floors. The sheet is highly reflective and is bonded between two layers of polyethylene bubbles, which can withstand more weight than foam board. The air gaps above and below the sheet prevent radiant heat from escaping, making it more efficient than foam board.

Best Insulation For Under Floors FAQs
Can insulation be added to existing under floors?
Yes, insulation can be added to existing under floors. In fact, it is a common practice to add insulation to under floors in order to improve energy efficiency and reduce heating costs. The process involves removing the existing floor covering and laying insulation material between the joists or on top of the existing subfloor. The type of insulation material used will depend on the specific requirements of the building, such as the level of insulation needed and the type of heating system in use. Some common materials used for under floor insulation include fiberglass batts, spray foam, and rigid foam boards. It is important to consult with a professional to determine the best insulation material and installation method for your specific situation. Adding under floor insulation can also help to reduce noise transmission between floors and improve overall comfort in the building.
How can I properly install insulation under floors?
To properly install insulation under floors, there are a few steps you should follow. Firstly, you need to assess the type of insulation you will be using. There are different types of insulation, including fiberglass batts, spray foam, and rigid foam boards. Once you have chosen the type of insulation that is best suited for your needs, you need to ensure that the area is clean and free of debris. You should also check for any moisture problems.
Next, you need to measure the area that needs to be insulated and cut the insulation to fit. Be sure to leave a small gap around the edges to allow for expansion. Once you have cut the insulation to size, you can begin to install it.
Start at one end of the area and work your way across, pressing the insulation firmly into place. If you are using fiberglass batts, be sure to wear protective clothing and a mask to avoid inhaling fibers. Once you have installed the insulation, you can cover it with a vapor barrier to prevent moisture buildup.
Overall, proper installation of insulation under floors is crucial to improve energy efficiency and reduce heating costs. By following these steps, you can ensure that your insulation is properly installed and will provide the maximum benefit.
How much insulation is needed for under floors to be effective?
The amount of insulation needed for under floors to be effective depends on various factors such as the climate of the area, type of flooring, and the level of energy efficiency you want to achieve. Generally, a minimum of R-13 insulation is recommended for under floors in temperate regions, while colder regions may require R-19 insulation or higher. However, if you have a higher budget and want to achieve maximum energy efficiency, you can opt for more insulation. Additionally, the type of flooring also plays a significant role in determining the amount of insulation needed. For instance, hardwood floors require less insulation than carpeted floors. It's always best to consult with a professional insulation contractor who can evaluate your specific situation and recommend the best insulation option for your under floors to be both effective and energy-efficient.
What are the benefits of insulating under floors?
Insulating under floors has numerous benefits, both for the homeowner and the environment. Firstly, it helps to keep the house warmer in the winter by preventing heat loss through the floors. This reduces the need for heating and can lower energy bills. On the other hand, in the summer, insulation can help to keep the house cooler by preventing the transfer of heat from the ground. This can help to reduce the need for air conditioning, which also leads to cost savings.
Insulation also helps to reduce noise levels in the house by absorbing sound and preventing it from travelling through the floors. This is particularly important in multi-story buildings where noise can easily travel between floors.
Another benefit of insulating under floors is that it can help to prevent dampness and condensation. This is because insulation acts as a barrier against moisture, preventing it from seeping into the house and causing damage.
Overall, insulating under floors is an investment that can pay dividends in terms of cost savings, comfort, and environmental benefits.
What type of insulation is best for under floors?
When it comes to choosing the best insulation for under floors, there are several factors to consider. The main purpose of insulation is to prevent heat loss and reduce energy consumption, so the insulation material should have a high thermal resistance or R-value. The type of insulation that works best for under floors depends on the type of flooring and the climate of the area.
For wooden floors, the best insulation type is batt or roll insulation made of fiberglass, mineral wool, or cellulose. For concrete floors, rigid foam insulation boards are the most effective. Spray foam insulation is also a good option for both wooden and concrete floors.
Another important factor to consider is moisture resistance. The insulation material should be able to resist moisture to prevent mold and mildew growth. Additionally, it is important to ensure that the insulation is properly installed to avoid any gaps that may allow heat to escape.
In conclusion, the best insulation for under floors depends on the type of flooring and the climate of the area. It is important to choose insulation with a high thermal resistance, moisture resistance, and proper installation to ensure maximum energy efficiency.
