Is It Worth Insulating Under Floorboards?

advantages-and-disadvantages-of-sip1_3.jpg

Does the floor in your sitting room tend to get really cold? Are you having trouble heating up the floor? Well, one of the reasons your floor is getting cold is because the floor is one of the paths that heat leaves your home by.

The majority of heat loss occurs through the roof. However, some 10 to 20 percent of heat loss is due to your floor.

We do not take it into account the draughts coming up through the floor.

So, if you are wondering is it worth insulating under floorboards, the answer is yes. And we will try to answer why.

Let’s start by mentioning a few things. First and foremost, adding extra insulation to your floor must comply with the relevant building regulations for where you live.

If required, a reputable installer will arrange this on your behalf.

Check Your Floor Type

One of the aspects you need to consider for is it worth insulating under floorboards in the type of floor you have. For example, older homes have suspended timber floors, which can be insulated by lifting the floorboards, and laying insulation between the joists.

New homes, on the other hand, usually have a ground floor made of solid concrete. You can add insulation on top, or replace the floor and insulate underneath.

If you do not have access to the space underneath your house, lift a corner of the carpet and underlay, and conduct a spot inspection.

When there is another flat beneath you, usually you do not need insulation under the floorboards. That is, when someone lives in that apartment. If the said apartment is empty, it draws heat from your apartment.

Floor insulation can last for more than 20 years. You are not just saving money, but you are reducing draughts as well, making for cosier conditions inside!

How Insulation Saves You Money

In the end, it all comes down to cash-and how much of it you save. We add insulation to reduce our energy bills. Every inch of insulation you add to your house helps.

Simple calculations say that when you add insulation under the floorboards you can save between £40 and £70 per year. Yes, that might not sound like a lot of money, but think of it long-term. 

If your floors are above heated spaces, such as the living room, you do not need to insulate the upstairs rooms.

However, if the floor is above unheated space, like the garage for example, you need insulation. If not, you are losing heat and your hard-earned cash.

How To Insulate With Spray Foam

Due to its expansive nature, spray foam is the ideal material for insulating under floorboards. In fact, you can use spray foam to fill any cavity, regardless of size or shape-something which traditional materials are unable to offer.

For your underfloor installation, you need an expert technician. Look for a technician and company with full BBA accreditation. This way, you can rest assured that your spray foam installation is completed to the highest standard, by an informed and experienced expert.

Spray foam does not allow any allergens through, making for an all round, healthier home.
