What is the Best Insulation for Floors?

Summertime is a good time to insulate your home if you want to feel more comfortable. Floor insulation is the process of insulating a floor by adding an insulating material beneath the house’s floorboards, which reduces heat loss from the floor into the ground. It also regulates the temperature, which helps control the temperature during the summer and is also great for keeping warm once the winter season rolls in. Floor Insulation is also the perfect solution to prevent droughts that may come through the house’s floorboards. At this point, you might be asking yourself – what is the best insulation for under floors? Read on to find out!

What is the Best Insulation for Floors?

Process

Before installing floor insulation in your home, you must thoroughly observe the floor type you currently have because this will significantly influence what kind of insulation will be best for your house.

There are two main ways to determine what kind of floor you have. If you have a basement or cellar in your house, you might consider taking a look at the ceiling and seeing if you have joists and undersides of the floorboards. If it does, then you might have a suspended timber floor. This type of floor is common if you have ventilation bricks on the outside of your house below the floor level. If ever you cannot access the space underneath the floors, then try lifting the corner of your carpet and underlay of the house for more access and observation regarding the floor type.

After determining the type of floor you have, you can have a conversation with the worker about how it will be conducted, what type of insulation is perfect for your house’s floor, and its building regulations.

Here are the following layers that are processed when installing floor insulation:

Concrete slab

If you want to have a qualitative floor, then the concrete slab method is for you. It is a reinforced concrete slab at least 4 inches in size. The concrete slab holds back dampness and stabilizes the floor, preventing vermin from attacking the insulation.

Construction foil and Insulation

This is done when a foil is placed directly onto the concrete and will offer extra protection against dampness. After that, the insulation is applied onto the construction foil loosely.

Pipes and screed

The pipes are required to be in central heating or floor heating before the screed can be put into place. The whole part can be finished with a screed layer that usually has a thickness of at least 3.15 inches in size.

Types of Insulation Floors

Insulation Boards

Insulations boards or EPS sheets are a material that is an expanded polystyrene sheet. It is one of the best-known floor insulation materials because EPS sheets are easy to install and have a high insulation value. It is evenly fixed on the ground when installed and is pressure-resistant, making sure that the floor will not crack nor collapse.

Polyurethane Spray

Polyurethane spray has one of the best thermal conductivity values out of all the floor insulation materials. It has an excellent solid seal and usually excludes holes or irregularities. The advantage of this is that Polyurethane spray is a free choice of floor insulation and has a quick installation.

Insulating Screed

Insulating screed is a combination of cement and insulation material. The insulation material exists because of polystyrene granules that have a diameter of 0.10 to 0.25 inches. An insulation screed is usually combined with another form of insulation material to get a good insulation value.

Advantages of Floor Insulation

Floor insulation ensures that you will have the average comfort temperature (20 degrees Celsius/68 Fahrenheit) in your home. A non-insulated floor usually has a temperature of around 11 degrees, while an insulated floor can make the temperature rise to a good 20 degrees. A study showed that the combination of ambient temperature and floor temperature affects comfortability. The research showed that a mismatch between floor temperature (14 degrees( and ambient temperature (24 degrees) can make people uncomfortable, while similar temperatures (20 degrees and 21 degrees) between the two make people feel the most comfortable.
