Floor insulation can help you save on your energy bills and reduce your CO2 emissions. The ground floor accounts for around 10% of heat loss of the average home.
Floor insulation, different options for different floors:
Except if they are above an unheated space (i.e. a garage) your upstairs rooms would not need to be insulated.
1. Floorboard insulation for suspended floors
Floor insulation under the floorboards of your ground floor can save you about £60 each year. If you can’t access the floorboards from underneath from a cellar or a basement, these will need to be lifted. Once this is done, the insulating material, such as mineral wool is laid between the joists. If you are good at DIY, you can do it yourself, you will find the materials in a large DIY store. If not, use a professional installer.
2. Skirting board insulation
To reduce the heat loss from your ground floor you can seal the gaps between floors and skirting boards. Fill the gaps with a tube of sealant. It is a cheap and easy solution and sealant is cheap and available in most DIY stores.
3. Solid floor insulation
A new home is likely to have a solid concrete ground floor. Solid floors lose less heat than suspended floors. It is worth insulating solid floors if they need to be replaced. A rigid insulation can be laid on the solid floor and the floor covering will sit on top of it. Please note that this method raises the floor level so electrical sockets may need to be refitted and doors may need to be trimmed.
