Our information and advice on floor insulation

Did you know that insulating under your floor is a great way to keep your property toasty warm, whilst also working to reduce your heating costs? There are a number of underfloor insulation options available, all of which work to keep that precious heat in your home. Read on to find out more about the underfloor insulation options available, and why you should consider underfloor insulation.

What is underfloor insulation?

Approximately 10% of the heat we lose in our homes is lost through the ground floor. This is why it is so important to insulate your home if you want to cut your energy bills and keep your home toasty warm, even in the harshest of winters. 

Underfloor insulation works to fill the gap below your floor on the ground floor of the house to ‘keep the heat in’ your home. This works by using insulation materials to fill in the areas of empty space where you could be losing up to 10% of your home’s heat.

Is it worth insulating under your floorboards?

For most homes, the answer is a resounding yes.

If you’re asking yourself if it is worth insulating under your floorboards, you need to consider how much of your home’s heat is lost through uninsulated areas such as underfloor space or in the loft. When this happens, you are essentially throwing money away by failing to trap the heat inside your home, so on those cold winter days when you have the heating cranked up high; you’re letting precious pounds escape.

Older houses with suspended floors and floorboards have a void under the floorboards. Here, you are likely to lose heat through the floor, however in homes with solid concrete floors this problem is less apparent. In homes with concrete floors, often built from the 1930s onwards, concrete floor insulation can be installed directly on top of the floor with a thin layer of solid insulation. 

It is worth nothing here that solid insulation on concrete floors is only really viable to install on new builds/extensions. This is because when the void has been filled in with concrete, it’s about 6 inches thick.

What other areas of your home can you insulate?

Underfloor heating is a great way to save money and to keep your home warm. However, there are other insulation options available with the ECO Home Grant to keep your house warm, even in the depths of winter. One option is loft insulation, which can help you to save approximately 25% of the warmth lost from your home. Find out more about loft insulation here. 
Another insulation option is wall insulation, which can help you to save considerable amounts of money over the long term. This includes cavity wall insulation which is suitable for most homes built after 1930, or solid wall insulation which works to insulate the outer wall of your home. Find out more about wall insulation on the ECO home grant.
