Floor Insulation: What Type Does Your Home Need?

People nowadays don’t understand how floor insulation can benefit their homes. It’s not just a case of preventing cold feet while you’re walking around the house.

About one-fourth of the heat in your home is lost because of poor insulation in the floor. But have you considered the consequences of that?

In the following paragraphs, we will explain what will improve with better insulation. We’ll also mention which material types you should look into.

Draughts don’t necessarily cause you to catch a cold. But they do weaken your immune system which allows for viruses to easily infect you.

If you get proper floor insulation, you will remove the source of the draught. Those spots are usually where your home loses a lot of heat.

The problem with some insulation materials is that they leave behind a lot of dust when installed. Fibreglass is of especially poor quality in that respect.

If you’ve used fibreglass insulation in your attic, your air conditioning unit could carry the dust throughout your home.

What you need is a material that is airtight and doesn’t end up forming dust due to ageing. Our SFUF under floor insulation acts as a barrier against air movement, whilst also blocking out water vapour.

Whilst were on the subject of product lifespan, we need to mention that the SFUF lasts for about 50 years.


As we said in the beginning, getting a good floor insulation solution is not just about keeping your feet warm.

Draughts are the primary cause of energy loss in the home. Why? Let’s say you have an air conditioning unit. ACs only move the air around the home to make it cooler or warmer, depending on your temperature setting.

If that cycle is disturbed by draughts, your AC will have a much harder time working. It will thus consume more energy in an inefficient way.

The same goes for heating units. Why stifle the performance of the system when you could easily improve your energy savings?

If you want efficiency for your floor insulation, we recommend SFUF MultiFoil. It can be used for the following:

  • Suspended ground floors
  • Suspended internal floors
  • Solid floors

Many homeowners end up getting too much insulation material and end up with a lot left over after an installation.

SuperFoil is great for any part of your home. Feeling a draught from the roof or through the walls? Go ahead and insulate those too.


Most of the time, yes. Properly insulating your floor can save you hundreds of pounds a year, depending on the size of your house or flat.

Of course, if you have neighbours above and below your flat, you might not need floor insulation at all. If you live in a two-story building, you may only need to insulate the first floor. The floor above will benefit from the heat below.

Don’t rely on that factor in your decision, however. Your neighbours could have poorly insulated flats, and that will not help you at all.
