What is Underfloor Insulation?
About 10 percent of the heat loss in any living space is through the floor/ground. Floor insulation is an effective and simple way to keep your home warm during cold seasons and reduce the electricity bills. The use of underfloor insulation reduces heat loss through the floor to a great extent and keeps your living space warmer for a longer duration.
Whether you have a concrete floor or a wooden suspended floor, improving the insulation of your floor could help you save up to an amount of £70 per year.
Before going further about underfloor insulation, the type of floor you have must be determined. There are 2 ways to do so;
1) If your place has a cellar or basement then some wooden joists must be visible to you and from below you might be able to see the undersides of the floorboards. If so, your place has a suspended timber floor. You are likely to have the same type of floor if you have ventilation bricks below the floor level outside your house.
2) If the underneath of the floor is not accessible to you, you will have to lift the carpet from a corner and underlay.
How does it work?
With underfloor insulation, you are not just kept warm during the winter, but your place stays cool during the summer. Underfloor insulation does not work by trapping heat, instead, it reduces the loss of heat. This results in a controlled airflow, where warm air doesn’t get in during the summer and cold air doesn’t get in during the wintertime.
Your home can be thought of like a thermos flask, with underfloor insulation. It keeps the cool air cool and warm air warm. Just as a thermos flask controls the temperature of what’s inside it, your floor insulation gives more control over your home’s airflow.
In underfloor insulation, a thermal barrier is provided in the room under the floor and the outside environment. This is very important as the common materials used for flooring such as ceramic tiles, timber floorboards, laminate, etc. have very poor insulating properties.
Types of Underfloor Insulation
There are different types of underfloor insulation, each type uses different materials with specific properties and purpose. So it is very important to choose carefully the type of underfloor insulation your home needs. The commonly used types of underfloor insulation are:
· Insulation Boards
· Polyurethane spray
· Insulating screed
Expanded polystyrene sheets also known as ESP sheets are one of the best materials that can provide good insulation. They are very easy to install and have a high insulating value. This insulating material must be installed on an even ground which is why priming the surface before installation is very important. The insulation boards must also possess resistance to pressure so that the floor won’t collapse or crack
Polyurethane spray is another commonly used underfloor insulation material. It seals off any irregularity or holes on the surface quickly. This insulation requires a professional to do the work as it requires special protective gear. This spray insulation is slightly expensive compared to board or sheet insulations. Usually, an insulated board is installed by the homeowners, on which a polyurethane spray is used to completely seal the flooring off.
Insulating screed is made of combining materials like cement and other insulating materials. These insulating materials usually comprise polystyrene granules with a diameter of 0.1 to 0.25 inches. Insulating screed is usually combined with other materials to offer more insulation and for sealing the floor perfectly.
Spray Foam Underfloor Insulation
There are 2 different materials that are commonly used for underfloor insulation. They are
Fiberglass Underfloor Insulation
Fiberglass is a popular choice among builders and homeowners when it comes to floor insulation.
Rigid Foam Underfloor Insulation
Rigid foam insulation is another popular choice as it is easy to fit in most cases. Let’s understand why it’s a popular choice
· Like fiberglass, rigid foam insulation doesn’t wrap or compress over time.
· Rigid foam is capable of rejecting moisture, which makes it a better choice for floors made of natural hardwood, that are prone to attacks by mold and stain
· Rigid foam insulation can be used with a radiant heat flooring component. This ensures you have the warmest flooring possible
Other materials of underfloor insulation include blankets, rock mineral wool, rigid boards, etc.
Benefits of Underfloor Insulation
Underfloor insulation is all about good results and making smart choices for a building project or home. Here is why you should install new floor insulation:
1. Floor insulation helps you to prevent heat loss through the floors
Though insulation won’t make your home floors feel warmer, as it’s the job of radiant heat to do so, with insulation less warm air will escape out through the floor, keeping your room warm for a longer time.
2. Insulation will keep you cool during hot climates
We all know that hot air rises. Insulation helps you to put a barrier between the floor and the ground beneath you, helping you to maintain a comfortable environment inside your home.
3. Drafts can be dramatically reduced by Insulation
This is a factor to notice for homes built above the ground or have a crawlspace. Insulation helps to fill potential air holes and keep the air from outside from entering your interior space
4. An effective moisture barrier is created between your floor and the outside world
Floors of your homes, especially hardwood floors are highly susceptible to moisture levels. Adding a layer of underfloor insulation can help to prevent your floorboards from staining your wood or warping
5. Insulation can help to avoid the freezing of pipes on very cold winter nights and days
Insulation can provide extra protection to the plumbing below your floor, from extreme cold weather and add to its durability
6. Floor insulation – a great improvement in spaces like a basement or garage
While installing full insulation to your place will be more effective, just adding floor insulation can help you save a lot and not bring a dent in your bank account.

There are some grants and government eco schemes available for underfloor insulation that can dramatically reduce the costs. If you are eligible, these schemes pay a certain percent of your total home insulation costs.
If your house has suspended wooden floors (and not the concrete floors) you might qualify for a grant for insulating below them.
If you qualify for an underfloor insulation grant, there is a chance for you to qualify for a grant to replace your gas mains central heating boiler which is not working. This comes as a part of a new Dual Measures ECO Grant Scheme.
