Why Are My Floors Cold?

Whether you have a solid, timber, or concrete floor, lack of proper insulation in a home’s floors can leave them cold, increase heat and energy bills, and generally make a home less comfortable. Installing insulation to your floors decreases heat loss from the floor into the ground and helps your house become more energy-efficient.

However, floor insulation must be installed correctly to yield optimal results. You should choose the right R-value based on your climate and local building code regulations. An R-value of at least 13 for underfloor insulation is recommended, according to the US Department of Energy.

How can you properly insulate your floors? In this article, we discuss some of the best insulation options and methods for floors to help you choose the right one.

Why Insulate Your Floors?

Floor insulation is the process of insulating a floor by adding an insulation material underneath your home’s floor joists or floorboards. Properly insulating your floors offers several benefits to homeowners, including:

1. Stop Heat Leakage

Floor insulation is made of materials that are highly effective at slowing down the flow of heat energy. Without proper insulation, heat can easily escape through your home’s flooring material. This makes it challenging to keep your building at a comfortable temperature, especially if it is extremely hot or cold outside. Installing insulation within your building helps slow down the transfer of heat, keeping indoor temperatures more comfortable.

2. Reduce Energy Bills

On average, heating and cooling costs account for around 46 percent of a home’s yearly energy bills. Uninsulated floors cause the conditioned air to escape more quickly, wasting the energy you’re spending your hard earned money on. Insulation helps your air conditioning and heating system to function more efficiently and effectively, helping you conserve energy and save on utility costs.

3. Decrease Moisture Damage

Most flooring materials, like wall-to-wall carpets, hardwood, and cork are susceptible to moisture damage. This can result in bigger problems such as mold and fungus growth. On the other hand, insulating your floors with moisture-resistant and anti-microbial insulation helps create a moisture barrier, stopping humidity from creeping into your building. It forms a barrier that’s particularly advantageous for houses with cold basements that lower temperatures indoors.

Effective Floor Insulation Materials

Let’s take a look at some of the best insulation materials that you can install in your home.

1. Spray Polyurethane Foam Insulation

Spray polyurethane foam insulation offers a quick and effective way of conserving energy and maintaining a more comfortable temperature within your house. It forms an air barrier that seals any openings and removes all air draughts. This effective combination of air seal and insulation creates an excellent system in comparison with other insulation materials or methods.

Even if there are any cracks in the floors, spray polyurethane foam insulation can effectively insulate them. That’s because the foam is sprayed on as a liquid and then quickly expands into foam, filling all corners and crevices. As spray foam insulation doesn’t sag, settle, or shrink, its effectiveness won’t decrease over time.

2. Fiberglass Insulation

Fiberglass insulation encompasses billions of tiny glass fibers that contain trapped air bubbles that slow down the flow of heat. These fibers are joined together with a binding agent and baked in an oven before slicing them into the right size and packaging them.

Fiberglass insulation is one of the most common types of insulation because it can be installed easily. It is an exceptional thermal insulator that also performs well as acoustic insulation. However, the effectiveness of fiberglass insulation depends on its thickness and R-Value.

3. Cellulose Insulation

Cellulose insulation contains cellulose cells that have natural insulating power. It is composed of shredded paper along with a fire-resistant chemical called borate. The paper is broken down into cellular fibers that offer insulation. This kind of insulation has a high R-value across all its types, making it very efficient in insulating your home’s floors. Moreover, cellulose insulation creates an exceptional seal to stop undesirable air leakage in or out of your home.

Manufacturers often make cellulose insulation by combining recycled newsprint, denim, and other materials. Therefore, it is an eco-friendly product to manufacture and discard. Plus, there aren’t many chemicals used in making cellulose insulation that could generate contaminants at any point in the insulation’s lifecycle.
