Your home’s insulation is a key factor behind why your home’s temperature fluctuates with the seasons. It’s a common misconception that insulation simply helps your home retain heat. If this were true, it would explain the hot summers, but you would expect to avoid drastic drops in temperature in the winter. Conversely, a lack of insulation might lead to a very cold home in the winter months but avoid overheating in warmer temperatures.
But you don’t just experience a home that is either too warm in the summer or too cold in the winter. It’s both. So what’s really going on? And how does insulation actually work? Insulation slows heat transfer. It reduces the rate at which energy is transferred through your walls, floors, and ceiling. This means the warm temperatures outside are slower to seep into your home in the summer, and in the winter, the indoor heat is slower to escape. One of the most popular benefits of insulation is that it can save money on energy bills. It is, therefore, mostly discussed in terms of preventing heat escape in the winter. This is why it may be misconstrued that insulation simply traps heat or keeps a property warm.
