Common Misconceptions About Cold Floors

Understanding the factors that contribute to a cold floor can help you resolve the problem and lead to added comfort and savings on your energy bills. This article explores some common myths about cold floors and details one of the most effective ways to address the issue.

Myth #1: If The Floor Is Sealed, It Won’t Get Cold

Let’s say that someone has been putting up with a cold floor for quite some time. While it hasn’t really been an issue in summer, it is always noticeable during the colder months of the year. Then one day they discover that there are several gaps in their flooring. At this point in time it would be a fair assumption for the homeowner to make that this must be why the floor is cold, so they set out to address the issue and seal up all the gaps in the floor. However, the truth is that while cracks in the floor do exacerbate the problem, and sealing gaps will improve the situation to a small extent, it won’t entirely solve the problem.

Myth #2: The Floor Is Cold Because Hot Air Rises

Yes, hot air rises, but this does not explain why the floor is cold. Materials lose their heat when they come into contact with something that is colder than themselves and which is conducive to heat transfer. Underfloor insulation provides the necessary barrier between the floor and the cold, outside air. Insulation slows down the transfer of heat, causing the flooring material inside to retain its heat, making it more comfortable during cold weather.

How Can Underfloor Insulation Reduce Energy Bills?

In winter, we generate warmth inside the home. Our thermostat recognises when the house has reached a set temperature and the heater is automatically switched off. The warmth stays in a well-insulated house even after the heater has turned itself off. However, up to 20% of heat can be lost through an uninsulated floor in winter. This means that the heating system has to keep on generating heat to maintain the desired temperature. The result is a higher energy bill. Heat can escape through the floor material itself, while cracks and gaps can allow cold air to enter. By sealing the gaps and installing insulation directly under your floor, you address both of these “leaks”.

Installing Underfloor Insulation in Existing Homes

Installing underfloor insulation can be a challenging task, depending on a number of factors. The most obvious challenge is the space underneath the floor of the house which is often limited. It requires a certain level of fitness to install underfloor insulation, with installers often lying on their backs for prolonged hours. While it may be possible to do it yourself, there is also the option of booking a professional installer to do the job for you.
