In the cold months of the year, we all want to stay warm in our homes, but sometimes it seems like no matter how high we set the thermostat, we are cold. If that is your case, then you might need to take a closer look at your insulation.
The measurement used to denote how well a material insulates is called R-Value. To make matters somewhat more complicated, however, a wall might have a different R-value as a whole than the insulation that is installed in it. Usually, this will be due to situations that decrease the insulations effectiveness in one way or another. If the insulation has been compressed in some spots, this can lead to it being less effective. Also, if there is damage to the wall, such as a hole or a crack through which the air from the outside leaks in, this too will lower the insulations effectiveness. Using an infrared camera, you will be able to find the areas of the wall that are cooler, which will let you know where the problem lies.
