It’s common among homeowners to assume that insulation is only relevant in winter. It’s created to keep the heat in when you’re spending money on warming your home, right? Well, yes, but it’s also essential for keeping the heat out in summer. People who live in warmer climates might be inclined to ignore the need for insulation, but it’s every bit as important in the heat as it is in the cold. Here’s everything you need to know.
How does insulation work?
Okay, first things first, let’s try to understand how insulation and heat transfer work. The fabric of insulation tends to be full of tiny air bubbles within its structure. These air bubbles make the perfect insulator, and stop heat transferring. This heat transfer is stopped in either direction, meaning that either heat coming in or out of the home is stopped in is tracks. That means, when the sun is beaming down on the roof of your home, the insulation in your loft is actually stopping most of it from making its way into your home. When a home gets warm during the summer, it tends to be from air moving in through windows and doors, and sunlight directly on windows. The insulation in the roof actually helps to cut most of it out. Foil insulation also has the same effect, but works in a different fashion. The foil is obviously very reflective, and this means it sends heat back the way it came, whether it’s back downwards into the home in winter, or back upwards towards the roof in summer.
Why does it help?
Well, the most obvious answer here is that it keeps the home more comfortable and the costs low. Whatever means you choose to heat your home, whether it’s log fire, gas central heating, or domestic gas oil such as from New Era Fuels, you’re keeping the cost of fuel down. When you require less fuel from your home, you don’t have to spend as much on oil, gas, or coal. In the summer, whether you’re running fans or air conditioning, these systems have to work harder to cool a home with less insulation. The more heat that comes in from outside, the harder these systems have to work, and the more money you have to spend on electricity to power them.
How can we maximise the use of insulation?
When your walls and roof are properly insulated, how can you maximise its effect in warmer weather? Well, the only other way for the heat from the sun to get into your home is through the windows, so using blinds, drapes, or even net curtains can seriously minimise this effect. The most important thing to remember is to optimise air circulation. At night, open all windows to move the warmer air outside, and close them and the blinds once the sun comes up. If the insulation in your home is of high enough quality, it should keep your ambient temperature at a comfortable level.
Remember, insulation is for life, not just for winter!
