Heat Lost Through An Uninsulated Floor: The Real Story
The housing stock in the UK is built to retain some heat, but construction materials are not good enough to retain it all.
A good proportion of the heat, paid for by homeowners all over the UK, is lost. That means that for the average gas and electricity bill of £1,1138 a year, a lot of money is being spent without any benefits to a household.
The locations of the heat loss are spread throughout a property, with no single area being responsible for the entirety of it. The main problem areas are walls and windows, the loft, roof and the floor.
Estimates on the exact heat loss in these areas vary, with the walls often stated to be responsible for around 35% to 50% of heat loss and the roof for 20% to 25% of the heat loss. But how much heat is lost through an uninsulated floor?
We’re going to be taking a look at the kind of heat loss that you can expect through the floor and what you can do to help your home retain as much of it as possible.
Heat Loss and Flooring: The Real Story
There are two standard types of flooring in UK homes, known as solid flooring and suspended flooring. Which type of flooring often depends on the age of the property.
For suspended flooring, there is the benefit of additional damp protection, as the flooring is raised off the ground. However by raising the floor, ample room for draughts is created, making the flooring cold.
For solid flooring, damp can be an issue, as the flooring is directly on the ground. However, there is no room for draughts, so the flooring may be warmer.
While the two flooring types are very different, the general estimated heat loss for all flooring is around 10%. This figure is a lot lower than the loft or walls, but still plays a key role in the amount of heat that a property is losing.
For floor insulation in suspended flooring, spray foam can be installed under the floorboards to stop draughts and heat loss without causing the flooring to suffer from reduced damp protection
Protecting Against Heat Loss – The Thermal Envelope
The walls, roof, and floor of a property all come together to form what is known as the thermal envelope. This is what is designed to prevent the loss of heat in the winter and the gain of heat in the summer - essentially the heat transfer of a property.
An uninsulated house doesn’t have an effective thermal envelope, so heat can transfer easily between the walls, roof, and floors. To solve the problem of too much heat transfer, the thermal envelope needs to be improved throughout.
This is something that is normally achieved by the addition of an insulation material. Insulation can be installed inside the walls, under the roof and under the floor to reduce heat transfer in the summer and winter.
The effectiveness of spray foam means that the reduction of heat transfer will be significant, which in turn, will lead to a great reduction in monthly and yearly energy expenditure – improving the energy efficiency of your home and reducing your energy bills
The Best Insulation for Heat Retention
Spray foam insulation is one of the best materials to improve the thermal envelope of a house, because it can be used to tackle all areas of a property effectively. You can install spray foam under the roof, between the walls and under (or on) the floor with ease.
For floor insulation in suspended flooring, spray foam can be installed under the floorboards to stop draughts and heat loss without causing the flooring to suffer from reduced damp protection.
For floor insulation in solid flooring, spray foam can be installed on the floor before new flooring material is added to reduce the heat loss and assist with damp protection.
The effectiveness of spray foam means that the reduction of heat transfer will be significant, which in turn, will lead to a great reduction in monthly and yearly energy expenditure – improving the energy efficiency of your home and reducing your energy bills.
