Is There Insulation Between Floors?

Can you insulate between floors? If you wonder whether there is between-floor insulation, the answer is yes—there is! After all, this is pretty popular, although not every house plans to insulate its floors in between.

What is the use of this insulation? The answer is pretty basic. You heard the name insulation, and that’s what it works for: to insulate the rooms. This is considered one of the best ways to prevent heat loss from room to room, enhancing energy efficiency.

It also serves as sound insulation, reducing noise transfer between different levels of your home, which is particularly beneficial in multi-story buildings.

Despite being said as one of the most effective ways to prevent heat loss, it doesn’t mean you should insulate your floors. According to some sources, most heat loss happens through the roof. That makes floor-through heat loss accounts for only 10-20% of the heat loss occurring in your house.

Though the number is pretty low, you can always insulate your floors in between after consulting a professional.

Should You Insulate Between Floors?

Again, the answer is this one: it depends on your situation. If you think your house often loses heat relatively quickly, you may consider insulating your floors. This would be excellent, especially if you are facing a cold winter and your house is affected pretty much.

In addition, you can insulate your floors in between if your budget is well-prepared. Adding insulation may cost you a fortune, especially if you are adding insulation to an already-built house.

If this happens, you (along with a professional) will need to reevaluate your house structure to decide what’s best for your house. After all, adding insulation is an optional choice—and consulting with a professional will help you save money if your house doesn’t need it.

To help you decide, we have summarized the pros and cons of insulating between floors in the explanation below.

Pros and Cons of Insulation Between Floors

How will floor insulation affect your house? Before you decide to insulate your house, you can read the pros and cons of insulating floors in between below.


  1. You have a warmer room

If your house is a two-story, adding insulation between your basement and first floor will make your room way warmer. Hence you will be readier for the winter.

  1. You can also save the space

If the heater makes your room look narrow, then insulation can help you to flee from this. Moreover, the insulation is hidden (between the floors). That said, your room will look more spacious with insulation.

  1. Less moisture on your floor

Heat cannot pass with the insulation installed. This means you will also have less moisture trapped on the floor.


  1. You may risk having the insulation wet

This may be caused by the leaking pipes which connect one room to another. If your insulation gets wet due to a leakage, you may have the insulation prone to mold.

  1. Difficult to install

Installing insulation will be more difficult if installed on an already-established building. This is because you need to redo the building to install it.

Well, those are the pros and cons of insulation between floors. Hopefully, this article helps you decide the best house option.
