Energy Efficiency through Under Floor Insulation
Floor insulation is probably one of the most important aspects that homeowners usually overlook. Sure, having aesthetically pleasing and durable floors is important, but what is equally important is them being comfortable to walk on no matter the temperature outdoors.
Adequate insulation can be a total game-changer when it comes to increasing the comfort of your home and reducing your energy consumption. So, if you own an old home, the chances are the floors are not properly insulated, which could be the cause of those hefty energy bills as well as pesky drafts.
Depending on the size of your property, the cost can go from a few hundred pounds to a couple thousand. The good news is that the UK government is offering a free under floor insulation grant of up to £7,500 to eligible and low-income households to cover the cost of underfloor insulation.
This means you can increase your house’s energy efficiency, lower energy bills, reduce carbon emissions, and enjoy under floor heating. No more cold feet when you make your morning cup of tea.
What Is Underfloor Insulation?
Underfloor insulation is the process of adding insulated materials in the gap under the floor, offering an extra thermal barrier. This helps keep your floors cool in summer and warm in winter while stopping drafts that come through gaps. So when heat tries to escape through the floors, the insulation will prevent this, and your house will stay warm throughout the year.
Your home could lose up to 20% of its heat through uninsulated floors. That’s like throwing away 20% of your heating bill! By investing in underfloor insulation, you’re not just making your home more comfortable with under floor heating; you’re also making a smart financial decision that will benefit you for years to come.
Why is Underfloor Insulation Important?
If your floors are already uninsulated or have very little insulation left, it is about time you invested in proper insulation. Doing so will not only keep your floors warm and comfortable to walk on, even barefoot, but you will also enjoy other benefits that you did not know existed. Here are a few reasons why underfloor insulation is extremely important.
Improve Indoor Air Quality
Underfloor insulation plays a huge role in improving indoor air quality and maintaining a healthier living environment all year long. Adding an extra layer between the gaps in the floor prevents moisture and dampness from seeping into the floorboards and causing mould, mildew, and other moisture-related issues. It helps maintain a dry and healthier living environment, which is an ideal living condition for people with allergies and respiratory problems.
Reduce Carbon Emissions
Insulating your underfloor means improving the energy efficiency of your house. This is because when floors are insulated, they minimise heat transfer, keeping the house warmer in winter and cooler in summer. As a result, you do not have to rely on your heating and cooling system that uses fossil fuels to operate. While it is recommended to upgrade your fossil fuel heating system as well to reduce energy consumption, insulating floors will definitely allow you to use them less than before. Therefore, you will use less energy, which directly translates to reducing your carbon footprint.
Save You Money
Underfloor insulation has more benefits than you can imagine. One great benefit is that you can get away with using your heating system less often, as the insulation will maintain a consistent temperature all the time. It keeps the heat trapped inside the house, improving its overall energy efficiency. This means you no longer have to pay a hefty energy bill every month just to keep your home warm or cool. So, whether you use your Free UFI grant or invest the money yourself, the insulation will pay for itself many times in its lifetime.
Increase Comfort
Drafts and cold spots on the floor can make the whole house feel chilly and uncomfortable. Well-insulated floors reduce the chance of drafts and cold spots near the floor, and this is especially true for older homes that have wooden floorboards. Proper insulation also makes your house soundproof, as it does not allow any unwanted outdoor noise to enter the house. This, as a result, makes the living environment inside the house more comfortable.
Increase Property Value
In the UK, properly insulated homes get a higher rating in Energy Performance Certificates (EPCs) like an A or B. Whereas uninsulated homes usually get a low grade like G. When your property is well-insulated, it gets one of two high grades, like an A or B. This indicates the lower energy consumption and higher energy efficiency of the home. This is important when you want to rent out or sell your home because people who want to rent or buy take these ratings very seriously. As a result, it increases the market value of your property compared to those houses with low EPC grade.
Types of Underfloor Insulation for Your Floor
Choosing the underfloor insulation for your home depends on various factors, such as the type of flooring, your budget, and insulation requirement. Here are common choices available for different floors:
- Suspended Timber Floor Insulation: If your home has wooden flooring, suspended timber floor insulation is the most suitable insulation for it. The materials used in this type of insulation usually include mineral wool, expanded polystyrene (EPS), polyurethane foam, and cellulose Insulation. This can reduce heat loss to almost 0%, preventing hot air from escaping through the floors. Plus, it stops any moisture from seeping into the wood floor, which can potentially cause structural damage.
- Solid Floor Insulation: While solid floors, also known as concrete floors, typically lose less heat compared to wooden floors, there is still insulation required to make sure the house is well-insulated and energy-efficient. The most common insulation materials for solid floors are rugs, poured concrete insulation, polyisocyanurate (PIR), mineral wool, extruded polystyrene (XPS), and expanded polystyrene (EPS). These materials make sure to trap the heat inside the house to keep it warm throughout the year, reducing the need to use more energy.
- Tiled Floor Insulation: Compared to solid floors and wooden floors, titled flooring is always a bit more challenging to insulate, whether you have ceramic, porcelain, granite, cement, or marble tiles. This is because the tiles are naturally colder underfoot, no matter the season. But this type of flooring is extremely durable and easy to maintain. So, the best types of insulation materials are rugs, radiant under floor heating systems, cork insulation, fiberglass batts or rolls, and polyurethane foam. These materials provide moisture resistance and increase the thermal performance of your house.
Are There Any Free Grants and Incentives Available?
If you don’t have enough private funding to invest in the underfloor insulation, the UK government is offering a free UFI grant of up to £7,500 under ECO (Energy Company Obligation) to encourage low-income households to improve the energy efficiency of their property. However, you need to check the eligibility criteria to receive the grant. To learn about the eligibility criteria, you can get more information about the grant on the Warmer Homes website.
You can also fill out the form here on the Home Energy Guide website, and an expert from our team will contact you to assess your property, identify problematic areas, and suggest insulation requirements accordingly. We will ensure that after the insulation, you receive a higher EPC grade and enjoy energy efficiency benefits for years to come.
