Everything You Should Know about Floor Insulation

If you’re thinking about starting a home improvement project, you might want to consider insulating your floor. By installing insulation, you’ll make your home warmer during the winter, which means you’ll cut back on your energy bills. 

Floors at ground level can be quite cold in winter, and insulating them is always a good idea. The floors on higher levels don’t need to be insulated if the upstairs rooms are being heated. 

But if these rooms are not heated, you could benefit from installing floor insulation. So, if you want to make your toes toasty and start a floor insulation project, make sure you keep on reading.

Costs and savings

If you already have wall and roof insulation, you might think there’s no need to insulate your floor. However, even up to 15% of the heat in a room can escape through uninsulated floors. 

Therefore, installing floor insulation is a guaranteed way to staying warm during the cold winter months. Moreover, if warm air doesn’t escape from your home, you’ll need less energy to heat the entire place and this will definitely help you save money. 

And if you know how to install it yourself, floor insulation will pay off in about two years.

Floorboard insulation

If you have a suspended floor, you’ll need to insulate your floorboards. And the easiest way to do so is from underneath. So, if you have access to your floor from your basement or cellar, insulating your floor is going to be a real piece of cake. 

When insulation is installed from underneath, you have to secure it with netting stapled to or draped between the joists. Still, if you can’t access your floorboards from underneath, you’ll have to do it from the top. 

This is a bit more time-consuming option since it involves lifting your floorboards and fitting the insulation between the joists.

Solid floor insulation

Even though less warm air escapes when you have a solid floor, such as a concrete floor, you can still benefit from installing more insulation. This is usually done by laying a new layer of rigid insulation on your floor. 

Once you do that, you should cover the insulation with chipboard before you lay your desired floor covering. Also, when insulating solid floors, insulation can be placed either directly on top of the existing layer or installed in the form of a floating floor

You can also do this on your own, but bear in mind that insulating a solid floor is more difficult than insulating floorboards.

Tiled floor insulation

We all know that tiled floors tend to be quite cold. This is the case because the material does not retain the heat very well. Because of this, there’s really not much you can do to make your tile floor more energy-efficient. 

Of course, adding insulation to a tiled floor is possible before the tile is installed. But, when trying to add insulation to a room when tiles are already installed, the only thing you can do is check for any leaks and fix them as soon as possible. 

Make sure you also check both the skirting boards and the grouting between the tiles.

Rugs and carpets 

Having rugs or carpets on your floor is also a great way to make a place warmer. On top of that, having a floor covering will also help you block off draughts. 

Even though these won’t solve all of your problems, it’s always recommended that you place carpets or rugs on your floor. You can go for carpets in the rooms where you want the entire floor covered, while rugs are a perfect option for spaces where you want it partially covered. 

Area rugs can serve as a perfect insulator between the floor and your feet, and getting a couple of these is always a good idea.

Insulating the floor in your home may be just the project your home needed. Try doing it yourself or have experts do it for you, and you’ll be guaranteed to keep your home warmer during cold winter months and spend less on your energy bills.
